Atlas V to Launch NASA's TDRS-M Mission

Rocket/Payload: A United Launch Alliance Atlas V 401 configuration vehicle will launch the Tracking Data Relay System (TDRS)-M payload for NASA. Date/Site/Launch Time: Thursday, Aug. 3, 2017, from Space Launch Complex-41 at Cape Canaveral Air Force Station, Florida. Live Broadcast: Stay tuned for how you can watch live. Mission Description: The addition of TDRS-M to the Space Network (SN) will provide the ability to support space communication for an additional 15 years. The network consists of TDRS satellites that transmit data to and from ground stations on Earth for NASA missions and expendable launch vehicles. Without the Space Network, scientists, engineers and control room staff would be unable to readily access data from missions like the Hubble Space Telescope and the International Space Station. Launch Notes: This launch will be ULA's fifth of 2017 and 120th overall. A ULA Atlas V also launched TDRS-K mission in 2013 and TDRS-L in 2014. This mission will mark the 72nd Atlas V rocket since its inaugural launch in 2002. Launch Updates: To keep up to speed with updates to the launch countdown, dial the ULA launch hotline at 1-877-852-4321 or join the conversation at www.facebook.com/ulalaunch (https://www.facebook.com/ulalaunch), twitter.com/ulalaunch (https://twitter.com/ulalaunch) and instagram.com/ulalaunch (https://instagram.com/ulalaunch).

The next addition to NASA's Tracking and Data Relay Satellite (TDRS) System has arrived in Florida to begin processing for its August launch. The TDRS-M satellite, secured in a shipping container, was delivered Friday aboard a cargo aircraft that touched down at Space Coast Regional Airport in Titusville, Florida, near the agency's Kennedy Space Center. The spacecraft then was transported to the Astrotech Space Operations facility to begin preparations for launch aboard a United Launch Alliance Atlas V rocket.
TDRS-M will expand the capabilities of NASA's Space Network to support space communication for an additional 15 years. The network consists of TDRS satellites that transmit data to and from ground stations on Earth for NASA missions and expendable launch vehicles. The Space Network allows scientists, engineers and control room staff to readily access data from missions like the Hubble Space Telescope and the International Space Station.
Boeing Space and Intelligence Systems of El Segundo, California, built TDRS-M. NASA's Space Communications and Navigation Program, a part of the Human Exploration and Operations Mission Directorate at NASA Headquarters in Washington, is responsible for the TDRS network. Launch management of the Atlas V launch service for TDRS-M is the responsibility of the mission directorate's Launch Services Program at Kennedy.

CAPE CANAVERAL — A space-bound NASA satellite was hauled aboard a military transport aircraft from a Southern California factory to the launch site in Florida on Friday and its United Launch Alliance Atlas 5 rocket booster arrived by sea from the manufacturing plant in Alabama today.

The Tracking and Data Relay Satellite-M, or TDRS-M, is scheduled for launch Aug. 3 at 9:02 a.m. EDT (1302 GMT) from Cape Canaveral.

"The team is getting jazzed," TDRS Project Manager Dave Littmann said in a phone interview Friday.

"We are currently on track for an Aug. 3 launch date."

The craft was flown from Boeing's Satellite Development Center in El Segundo, California, to the Space Coast Regional Airport in Titusville, the town neighboring NASA's Kennedy Space Center in Florida.

The Boeing C-17 Globemaster III aircraft, operated by Air Mobility Command, flew a red-eye trek from Los Angeles International Airport across the country, touching down in Florida at 6:30 a.m.

Snug in its protective shipping container, the communications spacecraft was taken to the commercial Astrotech payload processing campus for the start of the launch campaign.

The satellite will undergo final testing, the loading of its in-space maneuvering fuel and encapsulation the rocket's nose cone while at Astrotech.

Meanwhile, the ocean-going Delta Mariner cargo ship delivered the Atlas 5's booster stage and Centaur upper stage to Port Canaveral today after an 8-day journey from ULA's production factory in Decatur, Alabama.

The vessel traversed 270 miles up the Tennessee River, 60 miles on the Ohio River and 646 miles down the Mississippi River. The trek then covered 815 miles through the Gulf of Mexico and around to Florida's east-central coast to the Cape, arriving at about 2:30 p.m.

The two-stage rocket will be stacked aboard the mobile launch platform at the Vertical Integration Facility in the coming weeks.

The TDRS-M satellite was built to provide follow-on and replacement capacity to maintain and expand NASA's Space Network communications infrastructure.

Operating from geosynchronous orbit 22,300 miles above Earth, TDRS-M will supply high bandwidth telecommunications services for data-relay and tracking low-Earth orbiting user spacecraft and launch vehicles, including the Hubble Space Telescope, the International Space Station and NASA's science observatories.

This spacecraft is the third and final built by Boeing under the third generation of TDRS satellites, joining TDRS-K launched in 2013 and TDRS-L in 2014 by the Atlas 5.

They are joined in orbit by the Boeing-built TDRS-H, I and J launched in 2000 and 2002 aboard Atlas 2A rockets for the constellation's second generation.

Four of the original generation, built by TRW and launched by space shuttles between 1983 and 1995, remain useful in orbit as well.

The TDRS satellites are clustered in three zones — the Atlantic, Pacific and Indian Ocean regions — to cover the entire globe with near-continuous communications.

The system was started in 1973 and saw its first satellite launched in 1983 to phase out and replace NASA's global grid of ground stations that severely limited contact with shuttle missions and unmanned spacecraft.

CAPE CANAVERAL — With the Atlas 5 rocket that will boost it into space now assembled and waiting, a $408 million NASA communications satellite is in final preparations for its science data relay mission.

The Tracking and Data Relay satellite-M, or TDRS-M, will be carried aloft by United Launch Alliance on Aug. 3 from Complex 41 at Cape Canaveral Air Force Station in Florida. A 40-minute morning launch window opens at 9:02 a.m. EDT (1302 GMT).

Built by Boeing, the geosynchronous spacecraft will act like a relay station 22,300 miles above Earth to receive telemetry, voice, video and scientific data from lower orbiting platforms — like the International Space Station and Hubble Space Telescope — and beam the signals to a central ground hub.

The satellite will become the 12th TDRS placed in space since 1983 and extend the constellation well into the 2020s, providing near continuous connectivity to spacecraft that would otherwise be in range of ground stations 15 percent of each orbit.

TDRS-M, standing 27 feet tall, currently resides at the Astrotech satellite processing facility in Titusville, Florida, having been fueled to its launch mass of 7,610 pounds.

It was shown to the news media today.

The craft arrived in Florida on June 23. Functional testing of the satellite bus, payload and propulsion system was completed by July 6 and propellant load wrapped on on Tuesday, July 11.

"We are right on schedule," said Paul Buchanan, TDRS deputy project manager.

The next step will occur next week when the craft is encapsulated in the Atlas 5 rocket's 14-foot-diameter, 42-foot-tall aluminum payload shroud that will protect the delicate satellite for the trek out of the atmosphere.

Then, the payload will be hauled through Kennedy Space Center to the Vertical Integration Facility at Complex 41 for lifting and mating to the launch vehicle on July 25.

The rocket arrived by sea on June 26, sailing into Port Canaveral from the manufacturing plant in Decatur, Alabama, aboard the Delta Mariner cargo ship.

On Wednesday, July 12, United Launch Alliance workers began stacking the two-stage Atlas 5 rocket, designated AV-074, by erecting the first stage aboard the mobile launch platform parked inside the VIF.

The combined interstage, Centaur upper stage and boattail of the fairing, all pre-integrated together off-site, was hoisted atop the first stage earlier today.

With the basic buildup complete, initial power-on testing begins tomorrow.

The 191-foot-tall rocket will be wheeled to the pad on Aug. 1 at 9 a.m.

No word on how this will impact the August 3rd launch target. A power up may be required to test the satellite which could delay encapsulation at least a week.

The AtlasV has been delivered to SLC-41 and into the vertical integration facility (VIF) for mating with the TDRS-M payload.

 July 16, 2017 (http://spaceflight101.com/atlas-v-tdrs-m/tdrs-m-launch-date-in-question-after-potential-damage-to-satellite/)

The launch date of NASA's TDRS-M communications satellite was called into question on Friday when the 3,450-Kilogram satellite suffered possible damage to one of its critical antennas during final processing work in preparation for launch atop an Atlas V rocket to reinforce the agency's Tracking and Data Relay Satellite System in charge of keeping astronauts on ISS and numerous NASA satellites connected to the ground.

TDRS-M is the final planned third-generation TDRS satellite, tasked with relaying data to and from low-orbiting spacecraft like ISS, the Hubble Space Telescope and some 40 NASA science missions plus satellites for other U.S. government agencies, aircraft, balloons and remote outposts in Antarctica. Conceived in 1973, the TDRS System became operational in the 1980s, allowing constant contact between Mission Control and astronauts on NASA's Space Shuttles and the International Space Station. Going through three generations, TDRSS steadily increased its data rates to deal with an ever-increasing volume of data collected by orbiting spacecraft.

TDRS-M is intended to deliver follow-on and replacement capacity to maintain and expand NASA's Space Network and ensure a continuation of services through the end of the 2020s when the International Space Station is expected to be retired. The TDRS satellites operate from Geostationary Orbit, 35,800 Kilometers in altitude with craft stationed over the Pacific, Atlantic and Indian Ocean to cover the entire planet and all orbital altitudes with three satellites in active duty and several previous generation craft still in a holding pattern to be called into action at a moment's notice.

Gearing up for a planned August 3 launch, TDRS-M arrived at the launch site on June 23 after a cross-country flight from Boeing's California facility to the Space Coast Regional Airport in Titusville. Taking up residence at the Astrotech processing facility in Titusville, TDRS-M planned to go through a set of final stand-alone tests and complete fueling for flight followed by encapsulation in the four-meter Atlas V payload fairing to be ready for its move to the launch pad at Space Launch Complex 41 at Cape Canaveral Air Force Station.

Reporters had a chance to visit TDRS-M (http://spaceflight101.com/atlas-v-tdrs-m/photos-nasas-tdrs-m-satellite-during-final-processing/) on Thursday before final work commenced on Friday to place the satellite onto its payload adapter prior to encapsulation next week. A mishap during Friday's operations may have caused damage to the satellite, NASA confirmed in a statement.

"NASA and Boeing are reviewing an incident that occurred during final spacecraft closeout activities on the Tracking Data Relay Satellite (TDRS-M) mission at Astrotech Space Operations in Titusville, Florida, on July 14, involving the Omni S-band antenna," the agency said in a statement issued on Saturday.

"The mission team is developing a plan to assess flight acceptance and the schedule forward. These additional activities are under evaluation for a planned TDRS-M launch Aug. 3, 2017, on an Atlas V rocket from Cape Canaveral Air Force Station in Florida."

Whether the August 3 launch date can be kept will depend on the scope of testing required to fully evaluate the antenna in question as well as the work needed if damage is detected.

The Omni S-Band antenna extends from the satellite's Earth-facing side (pointed up during processing & launch) and has the critical function of providing tracking, telemetry and commanding functions for the TDRS satellite, even if not pointing directly to Earth in case of an onboard anomaly. Other antennas on the TDRS satellite include two 4.6-meter steerable mesh antennas that deliver S/Ku/Ka-Band high-data-rate services to ISS, Hubble and various science satellites and an S-Band phased array antenna on the Earth-facing panel for multi-access lower data-rate communications with up to five missions at the same time.

Assembly of the Atlas V rocket slated to launch the TDRS-M mission was completed earlier this week – starting with the rollout of the Common Core Booster first stage that made its way to SLC-41 on Wednesday to be installed on the Mobile Launch Platform inside the Vehicle Integration Facility. The Centaur upper stage followed the next day to finish the two-stage Atlas V 401 stack for a set of testing activities prior to the installation of the encapsulated satellite that would clear the way for integrated testing ahead of rollout to the pad the day before liftoff.

WASHINGTON — NASA is continuing to investigate an incident during launch preparations for a communications satellite that threatens to delay its launch next month.

In a July 20 statement, NASA said it and spacecraft manufacturer Boeing were reviewing plans to replace an omnidirectional S-band antenna on the Tracking and Data Relay Satellite (TDRS) M spacecraft. That antenna was apparently damaged July 14 during final closeout activities at an Astrotech Space Operations payload processing facility in Titusville, Florida.

TDRS-M was, at the time of the incident, being prepared for encapsulation into a payload fairing and installation onto a United Launch Alliance Atlas 5 rocket. That rocket is scheduled to launch from Cape Canaveral, Florida, Aug. 3.

NASA, in both the July 20 update on the status of TDRS-M and the original July 15 statement about the processing incident, said that launch date remained under review. "An integrated launch team is assessing the Aug. 3 launch date," NASA said in the July 20 statement, and did not state when a decision about either proceeding with or delaying the launch would be made.

Complicating that process is a separate and unrelated issue with ground support equipment for the spacecraft at the launch pad. NASA said it was "evaluating a possible electrostatic discharge event" affecting that equipment, but did not elaborate on the severity of the problem.

The TDRS-M satellite is equipped with two S-band omnidirectional antennas, located on the forward and aft sides of the spacecraft. Those antennas are used for tracking, telemetry and command of the satellite itself.

The geostationary orbit satellites are also equipped with two parabolic antennas for Ka-, Ku- and S-band communications, a phased-array antenna that supports multiple S-band users and a dedicated space-to-ground antenna. Those antennas support communications with the International Space Station, Hubble Space Telescope and other satellites in Earth orbit.

TDRS-M is the third and final satellite in a series built by Boeing under a NASA contract awarded in 2007. The contract originally included two satellites with options for two more. NASA executed the option for just one of the two additional satellites. TDRS-K, now known as TDRS-11, launched in January 2013 and TDRS-L, now TDRS-12, launched one year later.

NASA, Boeing and United Launch Alliance (ULA) are reviewing a new launch date in August for the agency's Tracking and Data Relay Satellite (TDRS-M). NASA and Boeing need additional time to replace the spacecraft's Omni S-band antenna at Astrotech Space Operations in Titusville, Florida. A separate possible ground support equipment issue at Astrotech still is being assessed. TDRS-M will launch on a ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida. It is the latest satellite in a fleet of satellites supporting the space segment of the NASA's Space Network.

ЦитироватьTDRS-M given priority over CRS-12 Dragon as launch dates realign
July 26, 2017 by Chris Gebhardt

Launch delays are sometimes part of the equation in determining when specific missions launch in relation to each other. Sometimes, those delays occur to missions for the same agency, as is now the case with TDRS-M and CRS-12. With replacement operations to the TDRS-M omni antenna underway, NASA/United Launch Alliance has requested 10 August for the TDRS-M launch and SpaceX has requested 14 August for the CRS-12 Dragon launch to the International Space Station.

TDRS-M:

Спойлер

Determining mission priority for two missions for a single agency, as is now the case for TDRS-M and the CRS-12 Dragon resupply mission to the Station, can be somewhat tricky.

(https://img.novosti-kosmonavtiki.ru/209203.jpg)

Sometimes, launch contracts drive the priority decision.  Other times, the immediate need for a particular mission or its impact on subsequent missions/events drives which one gets priority. Still other times, the agency providing the launch vehicle and the launch service is instrumental – based on their own schedules and needs – in determining priority.

As the increasingly busy launch schedule off the Eastern Range in Florida (https://www.nasaspaceflight.com/2017/03/air-force-reveals-48-launches-year-cape/) this year has proven, all companies involved in the launch business are more than willing to negotiate launch dates with each other and to act as good neighbors when delays occur – which happen to every launch provider.
 
In the particular case of TDRS-M and CRS-12, priority determination came down to an assessment of the Omni antenna replacement on TDRS-M – an antenna that was damaged during final processing at the Astrotech facility in Titusville (https://www.nasaspaceflight.com/2017/07/tdrs-m-under-review-pre-launch-incident/).  That antenna replacement schedule revealed a No Earlier Than (NET) launch opportunity on 10 August 2017 on a United Launch Alliance Atlas V rocket (https://www.nasaspaceflight.com/?s=Atlas+V).

The issue then became that 10 August was the already requested and range approved launch date for the CRS-12 Dragon as well as the launch date the ISS Program (https://www.nasaspaceflight.com/?s=Space+Station) had for crew scheduling and an upcoming Russian EVA on the Station.

Nonetheless, as both missions are NASA flights, the agency had the ability to internally determine which mission had priority over the other. Given an identical NET launch dates for both missions, NASA opted to prioritize TDRS-M over CRS-12.

(https://img.novosti-kosmonavtiki.ru/209202.jpg)

As noted to the NASA Advisory Council (NAC) (https://www.nasaspaceflight.com/?s=NASA+Advisory+Council) yesterday by Greg Williams, Deputy Associate Administrator for Policy and Plans in NASA's Human Exploration and Operations Mission Directorate, replacement of the Omni antenna on TDRS-M occurred Monday at the Astrotech facility, with full up testing of the antenna now underway.

Replacement of the antenna is a positive step toward the requested 10 August launch of TDRS-M – even though NASA has yet to publicly announce that as the target launch date.

Nevertheless, according to Range information acquired by NASASpaceflight.com and available in L2, on Tuesday ULA requested 28 July for the MDR (Mission Dress Rehearsal) of the Atlas V and 10 August for launch of TDRS-M in a widow extending from 08:35 to 09:15 EDT (12:35 – 13:15 GMT/UTC).

Nonetheless, NASA is leaving open the possibility of a further slip to TDRS-M pending final antenna replacement testing. Should the satellite incur an additional delay, NASA will reevaluate which mission has priority – a discussion, should it become necessary, that will have an added element to the equation: the fact that CRS-12 Dragon has to launch at least two days before an upcoming 17 August Russian EVA at the Station or be delayed until "several days after" that EVA is complete.

ЦитироватьTDRS-M Flight Ready, Aug. 18 Launch Date Approved
Posted on August 7, 2017 at 5:39 pm (https://blogs.nasa.gov/tdrs/2017/08/07/tdrs-m-flight-ready-aug-18-launch-date-approved/) by Anna Heiney (https://blogs.nasa.gov/tdrs/author/aheiney/).

The Omni S-band antenna on NASA's Tracking and Data Relay Satellite (TDRS-M) has been successfully removed and replaced at Astrotech Space Operations in Titusville, Florida. An unrelated electrostatic discharge incident has also been resolved, and launch processing has resumed.  The spacecraft has been moved from the fueling stand and is now mated to the launch vehicle adapter as part of integrated operations with ULA.

The TDRS-M spacecraft is flight ready, and the Eastern Range has recently approved Aug. 18 as the launch date. NASA, Boeing, and United Launch Alliance (ULA) are targeting a 40-minute launch window that would open at 8:03 a.m. EDT. TDRS-M will launch on an ULA Atlas V rocket from Cape Canaveral Air Force Station in Florida.

NASA's Tracking and Data Relay Satellite-M (TDRS-M) has passed two more milestones as preparations continue toward liftoff. Launch of the newest addition to the agency's TDRS constellation is slated for Aug. 18 at 8:03 a.m. EDT from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

Processing activities at the Astrotech payload processing facility in nearby Titusville wrapped up with the TDRS-M spacecraft safely encapsulated in the payload fairing that will protect it through the early minutes of liftoff. The fairing arrived at the launch complex Aug. 9 after an early morning move from Astrotech. Now in position atop the United Launch Alliance Atlas V rocket, the vehicle and spacecraft will undergo additional testing ahead of launch.

ЦитироватьPhotos: Atlas 5 rocket assembled to launch data relay satellite for NASA
August 12, 2017 (https://spaceflightnow.com/2017/08/) Justin Ray (https://spaceflightnow.com/author/justin-sfn-ray/)

A United Launch Alliance Atlas 5 rocket that will boost NASA's Tracking and Data Relay Satellite-M, or TDRS-M, into space arrived at Cape Canaveral on June 26 aboard the Delta Mariner cargo vessel from the production factory in Alabama.

Flying in its basic two-stage configuration with no strap-on solids, the Atlas 5 was stacked aboard a mobile launch platform at the Cape's Vertical Integration Facility on July 12 and 13.

The pre-flight assembly process saw the first stage erected, followed the next day by the integrated interstage, Centaur upper stage and boattail.

TDRS-M was encapsulated in the rocket's nose cone at the Astrotech payload processing complex in early August, then transported through Kennedy Space Center and over to the VIF for hoisting atop the Atlas 5 on Aug. 9.

Liftoff is scheduled for Aug. 18 at 8:03 a.m. EDT (1203 GMT).

The U.S. Air Force 45th Weather Squadron has issued today's launch weather forecast. Meteorologists continue to predict a 70 percent chance of "go" weather at liftoff time, with thick clouds and cumulus clouds the primary concerns.

The Atlas V rocket is on the move this morning, making the short trek from the launch complex's Vertical Integration Facility, wh ere it was stacked and tested ahead of the flight, to the launch pad. The rollout is the final preflight move for the rocket and spacecraft, which will finish out the day in position for launch on Friday morning.

First motion has occurred and the Atlas 5 rocket's rollout to the launch pad is underway for Friday's liftoff.

The United Launch Alliance Atlas 5 rocket with the TDRS-M spacecraft aboard moved to the launch pad this morning for liftoff Friday to replenish NASA's data-relay infrastructure in space.

Спойлер

With the Tracking and Data Relay Satellite-M mounted atop the two-stage launcher, the 191-foot-tall rocket was rolled out from the vertical assembly building to the pad at Cape Canaveral's Complex 41.

Liftoff is scheduled for 8:03 a.m. EDT (1203 GMT) to deliver the 7,610-pound payload into an optimized high-perigee geosynchronous transfer orbit.

"This is a communications satellite. What is special is the comm it transports is primarily from our astronauts on space station. In that regard, it makes it unique and important," said Tim Dunn, the NASA launch director for TDRS-M.

The Atlas 5 began its third-of-a-mile trek to the launch pad with first-motion at 9:08 a.m. EDT (1308 GMT), arriving atop Complex 41 at 10 a.m. The first stage will be filled with 25,000 gallons of RP-1 fuel, a highly-refined kerosene, later today.

After a crew rest day Thursday to sync with the early morning launch, countdown clocks begin ticking just after 1 a.m. o Friday.

It will be the third time a TDRS has been launched by the Atlas 5 and sixth for the overall Atlas program.

The 401 version of the Atlas 5 will do the lifting this time. It has flown 36 times in the past 15 years, including 9 times for NASA's Launch Services Program.

Flying again on a well-understood launch vehicle eases some of the workload for LSP engineers and analysts to ensure the critical national asset gets into space successfully.

"It is generally smoother work because we can reuse a lot of the analysis that we have done for TDRS-K and TDRS-L on a 401, but it is the same level of technical rigor that we apply. We do reperform the thermal analysis, dynamic analysis, certainly the trajectory analysis. So on one hand, it's almost like a standalone mission, but we understand the 401," Dunn said.

Weather forecasters give a 70 percent chance of good conditions for launch.

The United Launch Alliance Atlas 5 rocket was transferred fr om its assembly building to the pad at Cape Canaveral's Complex 41 today for Friday's launch of NASA's Tracking and Data Relay Satellite-M that directly supports the International Space Station and various science missions.

Спойлер

Liftoff is planned for 8:03 a.m. EDT (1203 GMT).

The rocket was wheeled out aboard a mobile launcher platform, emerging from the hangar wh ere the rocket's two stages and the payload were stacked over the past month.

The slow drive from the 30-story Vertical Integration Facility to the launch pad used a pair of specially-made "trackmobiles" to carry the rocket's 1.4-million pound launching platform along rail tracks for the 1,800-foot trip.

The rocket is flying in the 401 vehicle configuration. The version features two stages, a four-meter-diameter nose cone and no solids. It is powered off the launch pad by an RD AMROSS RD-180 main engine. The Centaur upper stage has an Aerojet Rocketdyne RL10C-1 cryogenic engine.

Weather forecasters have improved the chances of acceptable liftoff conditions to 80 percent, with only a slight concern about cloud thickness.

"The spacecraft, Atlas 5 rocket and all Range equipment are ready, and the combined government and contractor launch team is prepared to launch TDRS-M -- a critical national space asset for space communications," NASA launch director Tim Dunn said at this morning's pre-launch news conference.

Clocks begin ticking at 1:13 a.m. EDT with power up of the Atlas and Centaur stages. Fueling the vehicle with cryogenic liquid oxygen and liquid hydrogen begins around 6 a.m.

"We rolled the vehicle out to the pad yesterday," said Scott Messer, ULA program manager for NASA missions. "So at the moment, the vehicle is just sitting over there waiting for us to get there this evening and begin the processing."

The historical odds of TDRS-M launching on the first try are 77 percent, based on the Atlas 5's previous countdowns over the past 15 years.

Of the 71 launches of Atlas 5 to date:

[/li]
• 38 have gone at opening of window on first attempt
• 17 went on first attempt but slipped later into the window
• 13 missions had scrubs (6-Technical, 4-Weather, 3-Range)
• 3 missions had more than one scrub
  

"It's a thrill for me personally to be here, just one day from the launch of this great TDRS satellite, which is a critical asset for the United States of America and all of space." Messer said.

Clocks are picking up the seven-hour sequence of work that will prepare the booster, payload and ground systems for blastoff at 8:03 a.m. EDT (1203 GMT).

The launch team will begin powering up the rocket to commence standard pre-flight tests. Over the subsequent few hours, final preps for the Centaur's liquid oxygen and liquid hydrogen systems will be performed, along with a test of the rocket's guidance system and the first stage propulsion and hydraulic preps, internal battery checks and testing of the GPS metric tracking system used to follow the rocket as it flies downrange, plus a test of the S-band telemetry relay system.

A planned hold begins when the count reaches T-minus 2 hours. Near the end of the 15-minute hold, the team will be polled to verify all is in readiness to start fueling the rocket for launch.

Supercold liquid oxygen begins flowing into the Centaur upper stage, followed by the first stage filling. Liquid hydrogen fuel loading for Centaur will be completed a short time later.

A final hold is scheduled at the T-minus 4 minute mark. That 15-minute pause will give everyone a chance to finish any late work and assess the status of the rocket, payload, Range and weather before proceeding into the last moments of the countdown.

The launch window today lasts 40 minutes to 8:43 a.m. EDT (1243 GMT).

"This will be the 72nd launch of an Atlas 5 vehicle, and of those 37 have been the 401 configuration. It has definitely been the workhorse of the family," said Scott Messer, ULA program manager for NASA missions.

Console operators have reported READY status during the pre-fueling readiness poll. The ULA launch director also voiced his approval for moving forward with the countdown today.

The loading of nearly 66,000 gallons of cryogenic liquid oxygen and liquid hydrogen into the Atlas 5 rocket will be getting underway a short time from now.

T-minus 2 hours and counting! The launch countdown has resumed for today's flight of the Atlas 5 rocket to deploy NASA's TDRS-M spacecraft that will operate 22,300 miles above Earth to relay vital communications to and from the International Space Station, Hubble Space Telescope and other satellites.

Clocks have one more built-in hold planned at T-minus 4 minutes. During that 15-minute pause, the final "go" for launch will be given. All remains targeted for liftoff at 8:03 a.m. EDT (1203 GMT) from Cape Canaveral's Complex 41.

In the next couple of minutes, chilldown thermal conditioning of the mobile launch platform upon which the rocket stands will begin. This is meant to ease the shock on equipment when supercold cryogenic propellants start flowing into the rocket.

Filling of the Centaur upper stage with about 4,150 gallons of liquid oxygen has begun at Cape Canaveral's Complex 41 following the thermal conditioning of the transfer pipes.

The liquid oxygen -- chilled to Minus-298 degrees F -- will be consumed during the launch by the Centaur's single RL10 engine along with liquid hydrogen to be pumped into the stage a little later in the countdown. The Centaur will perform two firings required to propel the TDRS-M spacecraft into the desired orbit today.

Now 60 minutes from liftoff. Today marks the 72nd flight for Atlas 5, born of the Air Force's competition to develop next-generation Evolved Expendable Launch Vehicles. In its previous 71 missions since debuting in August 2002, the Atlas 5 has flown 26 flights dedicated to the Defense Department, 17 commercial missions, 14 for NASA and 14 for the National Reconnaissance Office.
"NASA has a terrific record flying on Atlas 5. We've successfully launched 14 missions on this magnificent rocket -- missions to Pluto, Jupiter, the Moon, the Sun, radiation belts, three spacecraft to Mars, Asteroid Bennu, as well as two previous TDRS spacecraft. TDRS-M will be the 15th NASA mission on Atlas 5 and the 72nd Atlas 5 overall," said NASA launch director Tim Dunn.

Today's launch uses the 401 version of the Atlas 5 rocket, generating the necessary power to lift the TDRS-M spacecraft into a customized high-perigee geosynchronous transfer orbit.

Спойлер

It is the workhorse configuration of the Atlas 5, and is distinguished by two stages, a four-meter-wide nose cone, no side-mounted solid boosters and a single-engine Centaur upper stage.

The United Launch Alliance Atlas 5 rocket will come off the pad on 860,000 pounds of thrust produced by the RD-180 main engine.

Today's version, with the medium-length nose cone, stands 191 feet tall.
The 401 has flown 36 times before.

Final Mission in Series Completes Third Generation Space Communication Satellites

Atlas V TDRS-M Mission Overview (http://www.ulalaunch.com/uploads/docs/Mission_Booklets/AV/MOB_TDRSM.pdf)

Cape Canaveral Air Force Station, Fla., (Aug. 18, 2017) – A United Launch Alliance (ULA) Atlas V rocket carrying the NASA's Tracking Data and Relay Satellite-M (TDRS-M) lifted off from Space Launch Complex-41 Aug. 18 at 8:29 a.m. EDT. The TDRS-M is the third and final mission in the series of these third-generation space communication satellites to orbit, as part of the follow-on fleet being developed to replenish NASA's space Network.

Спойлер

"ULA uses the TDRS system as a primary means of receiving and distributing launch vehicle telemetry data during every flight. In fact, the TDRS-K and TDRS-L spacecraft, launched by ULA in 2013 and 2014 tracked today's launch" said Laura Maginnis, ULA vice president of Government Satellite Launch. "We are absolutely honored to have delivered this core NASA capability and critical national resource for our country."

All six of the newest TDRS satellites have been delivered to orbit on Atlas V vehicles.

This mission was launched aboard an Atlas V 401 configuration vehicle, which includes a 4-meter extended payload fairing. The Atlas booster for this mission was powered by the RD AMROSS RD-180 engine, and the Centaur upper stage was powered by the Aerojet Rocketdyne RL10C engine. This is ULA's 5th launch in 2017 and the 120th successful launch since the company was formed in December 2006.

"Congratulations to our entire ULA team and mission partners at NASA on another successful launch that will enable so many to explore and operate in space," said Maginnis.

The Tracking and Data Relay Satellite System (TDRSS) is a space-based communication system used to provide tracking, telemetry, command and high-bandwidth data return services. Microwave communications equipment and gimbaled antennae are the primary payload of each TDRS. The system is capable of providing near continuous high-bandwidth telecommunications services for Low Earth orbiting spacecraft and expendable launch vehicles including the International Space Station.  

With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 115 satellites to orbit that aid meteorologists in tracking severe weather, unlock the mysteries of our solar system, provide critical capabilities for troops in the field and enable personal device-based GPS navigation.

NASA's Tracking and Data Relay Satellite-M (TDRS-M), which is the third and final in a series of next generation communications satellites, has successfully been placed into orbit following separation from an United Launch Alliance (ULA) Atlas V rocket. TDRS-M launched Friday at 8:29 a.m. EDT from the Cape Canaveral Air Force Station in Florida.

Ground controllers report the satellite is in good health at the start of a four-month checkout in space by its manufacturer, Boeing. NASA will conduct additional tests before putting TDRS-M into service early next year. When ready, TDRS-M will become part of NASA's Space Network (https://www.nasa.gov/directorates/heo/scan/services/networks/txt_sn.html) providing navigation and high-data-rate communications to the International Space Station, NASA's Hubble Space Telescope, rockets and a host of other spacecraft.

Спойлер

"The TDRS fleet is a critical connection delivering science and human spaceflight data to those who can use it here on Earth," said Dave Littmann, the TDRS project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "TDRS-M will expand the capabilities and extend the lifespan of the Space Network, allowing us to continue receiving and transmitting mission data well into the next decade."

The mission of the TDRS project, established in 1973, is to develop, launch and deliver data communications relay spacecraft to support NASA's Space Network, which provides high-data-rate communications and accurate navigation. The TDRS-M spacecraft is effectively identical -- in both function and performance -- to the TDRS-K and -L spacecraft launched in 2013 and 2014, respectively.

The TDRS fleet (https://www.nasa.gov/directorates/heo/scan/services/networks/txt_tdrs.html) began operating during the space shuttle era with the launch of TDRS-1 in 1983. Of the TDRS spacecraft launched to date, only two have been retired and five of the nine operational satellites have exceeded their design life and continue to provide essential communications and navigation services.

Boeing conducted spacecraft integration and testing earlier this year at its satellite factory in El Segundo, California. After testing and confirming the spacecraft was ready for shipment, launch processing began following TDRS-M's arrival (https://www.nasa.gov/image-feature/tdrs-m-arrives-in-florida) in Florida June 23.

NASA's Space Communications and Navigation program, known as SCaN (https://www.nasa.gov/directorates/heo/scan/index.html), is part of the Human Exploration and Operations Mission Directorate at the agency's Headquarters in Washington, and is responsible for the Space Network. The TDRS project office at Goddard manages the TDRS development program. Management of the launch service for TDRS-M is the responsibility of NASA's Launch Services Program based at the agency's Kennedy Space Center in Florida. ULA provided the Atlas V rocket launch service.

TDRS-M satellite enables continued communication with International Space Station, Hubble Telescope

CAPE CANAVERAL, Fla., Aug. 18, 2017 – The sixth and final Boeing [NYSE: BA] Tracking and Data Relay Satellite (TDRS), launched today, will enhance NASA's space communications network when the satellite becomes fully operational early next year.

TDRS-M is the latest satellite in NASA's TDRS constellation and will provide high-bandwidth communications to spacecraft in low-Earth orbit. The TDRS network enables continuous communication with the International Space Station, the Hubble Space Telescope, the Earth Observing System and other programs supporting human space flight.

Спойлер

This is the sixth TDRS satellite Boeing has built for NASA, the first of which was delivered in 2000. After reaching its final orbit, the satellite will undergo testing and checkout before being declared operational.

"This TDRS-M milestone is another step forward in Boeing's commitment to developing technologies to support future NASA near-Earth, moon, Mars and deep space missions – and to do so affordably, drawing on our 40-plus years of strong Boeing-NASA partnership," said Enrico Attanasio, executive director, Department of Defense and Civil Programs, Boeing Satellite Systems.

Boeing has provided space communication services to NASA for more than four decades, and has been NASA's sole provider of tracking and data relay satellites since 1995.

 August 18, 2017 (http://spaceflight101.com/atlas-v-tdrs-m/photos-atlas-v-takes-to-the-skies-with-tdrs-m-data-relay-satellite/)

A United Launch Alliance Atlas V 401 rocket lifted of from Cape Canaveral's Space Launch Complex 41 at 12:29 UTC on August 18, 2017, carrying into orbit NASA's TDRS-M satellite, set to join the Tracking and Data Relay Satellite System supporting the International Space Station, the Hubble Space Telescope and dozens of NASA science missions orbiting the Earth.

Powering away from Florida's Space Coast with its RD-180 engine, Atlas V fired its first stage for four minutes before the Centaur upper stage took over for an initial 13.5-minute burn followed by 90 minutes of passive coasting prior to a brief re-light of the upper stage to inject the 3.5-metric ton satellite into a Geostationary Transfer Orbit.

 August 18, 2017 (http://spaceflight101.com/atlas-v-tdrs-m/videos-atlas-v-blasts-off-from-florida-with-tdrs-m-satellite/)

United Launch Alliance Atlas V 401 rocket lifted of from Cape Canaveral's Space Launch Complex 41 at 12:29 UTC on August 18, 2017, carrying into orbit NASA's TDRS-M satellite, set to join the Tracking and Data Relay Satellite System supporting the International Space Station, the Hubble Space Telescope and dozens of NASA science missions orbiting the Earth.

Powering away from Florida's Space Coast with its RD-180 engine, Atlas V fired its first stage for four minutes before the Centaur upper stage took over for an initial 13.5-minute burn followed by 90 minutes of passive coasting prior to a brief re-light of the upper stage to inject the 3.5-metric ton satellite into a Geostationary Transfer Orbit.

TDRSS builds a critical life line for astronauts aboard the International Space Station, delivers images fr om the Hubble Space Telescope and NASA's flagship Earth Observation Missions, and over 40 other scientific satellites as well as national security assets, aircraft and remote research stations in Antarctica. TDRS-M, the newest communications relay hub, will join the constellation as the final member in the third generation of TDRSS satellites, providing a boost in overall network capacity to handle ever-growing user demands, and ensure TDRSS can remain in service until the Space Station's expected retirement.

Atlas V – flying for the fourth time this year – thundered off fr om Space Launch Complex 41 at 12:29 UTC, 8:29 a.m. local time, rising into clear skies under the power of its two-chamber RD-180 engine that powered the vehicle until the first stage dropped away just over four minutes into the mission.

Assuming control of powered flight, the trusted Centaur upper stage was tasked with a customized mission profile to deliver TDRS-M to an optimized drop-off point – requiring a lengthy initial burn of over thirteen and a half minutes followed by a one-and-a-half-hour coast phase to set up for a short but critical re-start that lifted the 3.5-metric-ton satellite into its target Geostationary Transfer Orbit.

Loaded springs pushed the spacecraft away fr om the Centaur upper stage one hour and 54 minutes after Friday's launch and the craft checked in with ground stations to set the stage for a ten-day climb into Geostationary Orbit wh ere its velocity will match that of Earth's rotation to allow the satellite to remain in a fixed position in the sky. TDRS-M will be re-named TDRS-13 upon reaching operational status around five months after launch, entering the constellation over the Atlantic to deliver additional capacity to deal with growing user demands.

The Tracking and Data Relay Satellite System (TDRSS) was established in the 1980s after NASA identified the need for near-constant coverage of the Space Shuttle's orbit to remain in touch with the astronauts on board. Before TDRSS, NASA used a series of ground stations that only provided sporadic coverage, considered sufficient for robotic probes and satellites but making for some tense gaps in communications during the early Mercury and Gemini missions.

TDRSS functions by deploying a series of communication relay satellites in three locations in Geostationary Orbit, over the Atlantic (TDRS-East), Pacific (TDRS-West) and TDRS-Z over the Indian Ocean, covering what is known as the Zone of Exclusion – a small blind area between the eastern and western satellites. Featuring different antennas, the satellites relay data from lower-orbiting spacecraft to ground terminals in Guam and New Mexico from wh ere data is routed to the respective users.

The most prominent user of TDRSS is the International Space Station, using high-rate communications to beam down a plethora of video and data feeds from dozens of scientific experiments on the inside and outside of the complex while low-rate communication links are used to provide a near-continuous voice link between Mission Control and the crew. TDRS also provides standard-of-living services for the crew like video-conferencing with their families, TV uplink and Internet access, using TDRS as a relay from the ground to a LEO spacecraft.

Beyond ISS, TDRSS supports other NASA flagship missions like the Hubble Space Telescope and the Landsat program that has kept watch over Planet Earth for over four decades. All in all, TDRSS is relied on by dozens of NASA missions and other users like the Department of Defence to keep in contact with some of its classified space assets.

A total of 13 TDRSS satellites were launched since 1983 – six of seven first generation satellites were successfully orbited by the Space Shuttle (one was lost in the Challenger accident), three second-generation satellites were lifted by Atlas IIA rockets and three third-generation satellites launched between 2013 and 2017. TDRS-M joins nine satellites that remain in service, seven as part of the active constellation and two older ones are in a position to be called upon as spares.

TDRSS 3rd Generation – Image: NASA

In addition to covering satellites in orbit, TDRSS also relays communications for aircraft, balloons and remote ground stations as well as rockets on their way into orbit. In fact, Friday's TDRSS launch was supported by TDRS-12 that made its way into orbit on an Atlas V three years ago and this time covered the first Centaur burn while TDRS-7 provided communications in the later stages of flight when Centaur was over the Indian Ocean.

The three third-generation TDRSS satellites are essentially carbon copies with TDRS-M being the 76th and final Boeing BSS-601HP satellite to leave Earth. Once among the most popular communications satellite platforms, BSS-601 has been replaced with the much-improved 702 series but NASA decided in 2007 when ordering TDRS-K and L to stick with the well-proven 601 platform and TDRS-M was ordered in 2011 to follow suit.

TDRS-M, often likened to certain kinds of florals or cocooned insects with its antennas and appendages stowed, weighs in at 3,454 Kilograms and stands 8 meters tall when packed for launch. Once in orbit, the craft will deploy a pair of power-generating solar arrays, two 4.6-meter mesh antennas for single-access, high-rate links, a 1.9-meter antenna facilitating the space-to-ground-link and a phased array on the Earth-facing side will provide multi-access links to several spacecraft at the same time. Each single-access antenna supports one spacecraft at a time, typically the ISS (when in view) and one other craft – used for high-data rate burst downlink of stored onboard data.

Single-access services are available in three bands – Ku/Ka-Band is employed for very high data rates up to 800 Mbit/s for the return link and S-Band rates can be as high as 25 Mbit/s. Multi-access allows each TDRSS satellite to receive and send data to up to five other satellites at the same time.

TDRS-M comes with a price tag of $289 million, awarded to Boeing under a fixed-price contract as NASA exercised its option for a third satellite, foregoing an additional option for a possible TDRS-N. The craft's launch contract was awarded to ULA in 2015 for $132.4 million.

Friday's launch of Atlas V AV-074 was preceded by a smooth countdown for the workhorse launcher, starting just after 1 a.m. local time to power up the two-stage rocket and press into a lengthy testing operation to verify all systems were in readiness for the mission. Range instrumentation was set up and radio checks with Atlas V were performed around the L-4-hour mark followed by the final close outs at the launch complex to clear the way for fueling.

Cryogenic tanking picked up when the countdown resumed from a 15-minute pause at the T-2-hour mark to load Atlas V with Liquid Oxygen oxidizer and Liquid Hydrogen fuel. 94,600 liters of Rocket Propellant 1 had been filled into the first stage after Wednesday's rollout, leaving only the supercold cryogenics to be loaded during the count – a sequence taking 90 minutes.

>> Atlas V Launch Vehicle Overview (http://spaceflight101.com/spacerockets/atlas-v-401/)

Tanking was by the book as the first stage received some 185,000 liters of the -183°C oxidizer while the second stage was loaded with 15,700 liters of LOX and 48,100 liters of the even colder LH2, stored at -253°C.

With all tanks in topping and a refined version of the flight profile uploaded to Atlas V, the vehicle entered some final preparations for automated countdown while TDRS-M switched to battery power to be ready for its climb to orbit.

The launch had to be pushed into the day's launch window opening at 12:03 UTC due to an anomalous condition on the RL-10C engine of the Centaur upper stage that was slow to reach the required temperature on its oxidizer turbopump. The issue was traced back to a ground support line and teams adjusted the engine's chilldown pressures to coax the pump temperature into the desired range. This delayed liftoff by 26 minutes.

With issues resolved and excellent weather, all support stations provided a unanimous GO to allow Atlas V to enter the fast-paced four-minute auto sequence to pressurize its tanks, arm the Flight Termination System, switch to battery power and take over control from ground systems for the final automatic checks leading up to engine start.

The Russian-built RD-180 ignited at T-2.7 seconds in a carefully controlled sequence to reach a launch thrust of 390 metric-ton-force to lift the 335-tonne vehicle off its pad. Computers verified RD-180 was running smoothly before releasing the 58-meter tall Atlas V rocket to begin its climb into orbit.

With no Solid Rocket Boosters, Atlas V made the typical graceful liftoff – gimbaling the two nozzles of the RD-180 to keep the rocket in a vertical posture for the first 18 seconds of the mission. The NPO Energomash engine showed stable performance as Atlas V swung to the south-east, pitching and rolling to begin its trek toward Geostationary Transfer Orbit.

Atlas V pushed through the sound barrier after eighty seconds, encountered Maximum Dynamic Pressure at T+1:32 and had shed half its liftoff weight two and a half minutes into the flight as the RD-180 continued guzzling down 1,150 Kilograms of propellant per second.

BECO, Booster Engine Cutoff, was called four minutes and two seconds after liftoff with RD-180 gradually throttling back in the closing seconds of its burn to lim it acceleration on the vehicle. Cutting charges separated the spent Common Core Booster and the 32.5-meter long first stage was pushed clear of Centaur by eight small retrorockets.

Performance on the CCB was noted as near-nominal, within pre-flight predictions.

The trusted Centaur upper stage – conducting its 243rd mission – immediately headed into purging of its reaction control system and pre-started the RL-10C engine before ignition four minutes and 18 seconds into the flight. Just eight seconds later, Atlas V split open and dropped its payload fairing as the vehicle had reached the tenuous upper atmosphere were aerodynamic forces could no-longer hurt TDRS-M's delicate mesh antennas.

Centaur conducted a lengthy first burn, firing the 10,400kgf RL-10 engine for just over 13 and a half minutes to reach an elliptical Parking Orbit as part of a customized mission design. The burn went by the book and Centaur settled down in an orbit of 183 by 25,680 Kilometers, 27.0° for a coast phase of 90 minutes.

The coast phase was extended over past TDRS missions on Atlas V to optimally use the recently-introduced RL-10C engine and reach the best possible injection orbit. In essence, extending the coast by eight and a quarter minutes bought the satellite an additional two years of service life by delivering it to a higher-energy injection orbit and so save fuel on the climb into GEO.

While coasting, Centaur finished its Atlantic-crossing, flew over Sub-Saharan Africa & Madagascar and then headed out over the Indian Ocean as it gained altitude – targeting the second burn slightly over the halfway-point up to the high-point of the Parking Orbit. Re-start of Centaur was confirmed one hour and 48 minutes into the flight and the burn ran the expected 56 seconds. Navigation data from the upper stage showed an injection orbit of 4,644 by 35,790 Kilometers, 26.23 degrees – very close to the target 4,640 x 35,788km, 26.2° orbit.

TDRS-M Deployment – Image: NASA

TDRS-M separated from Centaur one hour and 54 minutes into the flight and checked in with a tracking station in Australia just over a minute after deployment, sending back status telemetry to confirm its health in orbit. Engineers will conduct detailed tests of the satellite before beginning a series of apogee-maneuvers with its R-4D engine to spiral up from its elliptical drop-off point into the Geostationary Belt over the equator to begin five months of testing ahead of at least 15 years of active service.

Friday's launch was the 72nd for the Atlas V since its inauguration in 2002 and the 120th mission for United Launch Alliance. It was the 37th flight of the Atlas V 401 variant, the 50th of the Atlas V 400 series and the 59th Atlas V from Cape Canaveral. It also marked the 654th launch of a vehicle named Atlas, going back to the early days of space flight in 1957.

ULA fans will not have to wait another four months for the next mission as a series of launches is lined up before the end of the year, involving Atlas V, Delta IV and Delta II vehicles. The next missions on the manifest are two secretive deliveries for the U.S. National Reconnaissance Office in September from Florida and California, pending readiness of the payloads.

ЦитироватьAerojet Rocketdyne Supports Launch of Satellite for NASA's Space Network

SACRAMENTO, Calif., Aug. 18, 2017 (GLOBE NEWSWIRE) -- Aerojet Rocketdyne, Inc., a subsidiary of Aerojet Rocketdyne Holdings, Inc. (NYSE:AJRD), successfully supported the launch of the latest Tracking and Data Relay Satellite (TDRS-M) for NASA's Space Network. The mission was launched from Cape Canaveral Air Force Station in Florida aboard a United Launch Alliance Atlas V rocket. Aerojet Rocketdyne propulsion systems on the Atlas V included the RL10C-1 upper-stage engine, six helium pressurization tanks, and 12 Centaur upper-stage Reaction Control System (RCS) thrusters. The TDRS-M satellite carries an Aerojet-Rocketdyne R-4D 100 lbf bipropellant engine for moving the satellite from its launch tip-off into geosynchronous orbit.

"The Space Network is vital for scientists, engineers and control room staff to access data from Earth-orbiting satellites, most notably the International Space Station and the Hubble Space Telescope," said Aerojet Rocketdyne CEO and President Eileen Drake. "It's a privilege to know our propulsion systems have once again been called upon to deliver the TDRS satellites into orbit with 100 percent mission success, enabling the continuation of scientific exploration for years to come."

Aerojet Rocketdyne's RL10C-1 upper-stage engine ignited after separation of the first stage to place the payload into orbit, helped by the Centaur RCS thrusters and pressurization tanks. The RL10C-1 delivers 22,890 pounds of thrust to power the Atlas V upper stage, using cryogenic liquid hydrogen and liquid oxygen propellants.

The RL10C-1 was developed from the RL10 family of upper-stage engines, which has accumulated one of the most impressive track records of accomplishments in the history of space propulsion. More than 480 RL10 engines have supported launches over the last 50 years, playing a vital role in placing military, government and commercial satellites into orbit, and powering scientific space probes on every interplanetary mission in our solar system.

The 12 MR-106 RCS thrusters are assembled in four rocket engine modules and provide pitch, yaw and roll control for the Centaur upper stage as well as settling burns prior to firing the RL10C-1 engine.

ARDÉ, a subsidiary of Aerojet Rocketdyne based in New Jersey, manufactures the pressure vessels on the first and second stages of the launch vehicle.

The Space Network was established in the early 1980s to replace NASA's worldwide network of ground tracking stations. It consists of a constellation of geosynchronous satellites, known as TDRS, which transmit data to and from ground stations on Earth for NASA missions and other orbiting satellites, including the International Space Station and the Hubble Space Telescope. According to NASA, the addition of TDRS-M will enable the Space Network to support space communication well into the next decade. With the TDRS-M, there are now 10 TDRS spacecraft in orbit around Earth.

Aerojet Rocketdyne is an innovative company delivering solutions that create value for its customers in the aerospace and defense markets.

ЦитироватьAtlas 5 rocket delivers NASA data router into space for astronauts and satellites
August 18, 2017 (https://spaceflightnow.com/2017/08/) Justin Ray (https://spaceflightnow.com/author/justin-sfn-ray/)

CAPE CANAVERAL — Bulking up NASA's constellation of tracking stations in the sky that provides critical links between orbiting spacecraft and ground control, a United Launch Alliance Atlas 5 rocket successfully deployed a new communications hub in space today.

NASA's Tracking and Data Relay Satellite series, a program that revolutionized mission operations for U.S. human spaceflight and robotic craft, is now in its fourth decade and this morning orbited its 12th satellite.

"TDRS is a critical national asset have because of its importance to the space station and all of our science missions, primarily the Hubble Space Telescope and Earth science missions that use TDRS," said Tim Dunn, NASA's TDRS-M launch director.

With its main engine running at full throttle, the Atlas 5 booster lifted off at 8:29 a.m. EDT (1229 GMT) fr om Complex 41 at Cape Canaveral.

The 191-foot-tall rocket, generating 860,000 pounds of thrust, aimed eastward and accelerated out of the atmosphere with NASA's TDRS-M spacecraft.

Within just five minutes, the rocket had shed 92 percent of its liftoff weight and transitioned to the high-energy Centaur upper stage.

An elliptical parking orbit was achieved within 18 minutes of takeoff, beginning a 90-minute quiescent coast higher through space to reach the optimum conditions for the second burn by Centaur.

That minute-long boost over the Indian Ocean propelled the 7,610-pound payload into a customized high-perigee geosynchronous transfer orbit.

The spacecraft was deployed by the launcher at T+plus 1 hour, 53 minutes to cheers and handshakes all around.

"Obviously, there is a lot of relief on the team right now, a lot of celebration, a lot of excitement. I love spacecraft separation. It is the best part of a launch campaign," said Dunn.

"So many hours are spent getting to this exact point when you know you have a healthy satellite that just separated fr om the launch vehicle about to go do its mission that it was intended for."

It marked the 143rd consecutive successful Atlas program launch spanning more than two decades, the 72nd for an Atlas 5 and the 120th for United Launch Alliance.

What's more, it was the 15th NASA use of the Atlas 5 and 28th mission conducted by ULA for NASA, all done successfully.

The Centaur, with its job completed, was expected to fire its engine later to reach a safe disposal orbit with a perigee above the usable low-earth orbit regime and apogee beneath the geosynchronous belt to guard against orbital debris.

Contact was established with TDRS-M, allowing controllers to determine that the satellite was healthy following arrival in space. The craft was the 76th and final to be built on Boeing's 601 satellite design, and it's successful launch was the 68th for the program dating back 25 years.

The first order of business for TDRS-M will be severing the straps that held the craft's two 15-foot-diameter graphite composite mesh antennas partially curled like taco shells to fit within the rocket's nose cone for launch.

"We need them unfurled and full shape to provide the RF performance for the communications services that our mission is founded upon. So one of the first things that happen after we release fr om the Centaur is we cut the furling straps and unfurl our reflectors It will take a period of a month or so to what we call 'relax' and return to their original shape to give us the full performance," said Dave Littmann, NASA's TDRS project manager.

While giving the antennas time to relax, orbit-raising maneuvers using the satellite's onboard main engine will be conducted over the next two weeks to achieve a circular geosynchronous orbit over the equator.

"We need about five burns that will take us from the drop-off spot to the geosynchronous location wh ere we will be operating the spacecraft for its lifetime," Littmann said.

"From there, we go through the deployments. We unfold the solar arrays and deploy our antennas — those unfurled big reflectors and the Space-to-Ground Link antenna, it's smaller but still critical to the mission. The SGL is the lifeline to the ground. That process takes 3-5 days."

If all goes well, control of the satellite will be handed from Boeing's facilities in California to NASA's White Sands Complex in New Mexico about three weeks after launch to begin on-orbit checkout.

"The government hasn't accepted the spacecraft yet. All of the on-orbit testing (is done) from the White Sands Complex with a Boeing team to check the spacecraft out — the bus and the payload — to make sure all of our RF communications services are ready. About four months after launch, in January or so, we will look to schedule an On-Orbit Acceptance Review to review all of the data accumulated   from the test program and determine, hopefully, that the government is in position to accept the spacecraft from Boeing. For the whole period to that point the spacecraft is Boeing's responsibility," Littmann said.

All of that testing will occur with the satellite parked over 150 degrees West longitude. Once NASA takes acceptance of the craft, the agency's Space Network assumes ownership, performs its own one-month checkout and then repositions the asset, likely over the Atlantic Ocean Region, Littmann said.

The $408 million TDRS-M was built and launched with the sole purpose to extend the useful life of NASA's constant communications infrastructure, supporting the astronauts around-the-clock aboard the International Space Station, supplying contact with the Hubble Space Telescope and transmitting the data from almost 40 science spacecraft studying Earth's environment and space.

"The (TDRS-M) spacecraft continues our ability to provide a data path for communications and tracking services from all of the different users out there in orbit today from human spaceflight component of NASA to robotic missions," Littmann said.

Looking down from the vantage point of geosynchronous orbit, the TDRS network receives signals from vehicles like the space station flying at a mere 250 miles above Earth and routes the telemetry, voice, video and science information to a dedicated ground terminal for delivery to Houston.

No matter wh ere the space station is located at any given moment, TDRS has the outpost in sight for the two-way communications.

"It works really well...We are almost spoiled now with how much communication we have. It really makes the science output and the ability to operate space station as miraculous as it is," said astronaut Stephen Bowen.

The TDRS system was born in 1973 to keep astronauts and satellites in constant contact with mission controllers, closing the substantial gaps every orbit as spacecraft passed into and out of range of ground stations scattered around the globe.

When TDRS first became operational in late 1983, the initial space shuttle mission to use the system relayed more information to the ground during its 10 days in orbit than in all 39 previous American manned spaceflights.

Relying on dispersed ground stations was a costly requirement and subjected the sites' operators to dangerous conditions in far-off countries, yet the system provided only 15 percent communications capability per orbit.

NASA currently has 7 operational TDRS satellites — two launched by the space shuttle in 1993 and 1995 and five Atlas-launched birds from 2000 to 2014, plus two aged shuttle-era craft from 1988 and 1991 now held in reserve with diminished capabilities.

"We need at least 6 active spacecraft and one active spare, so we need at least 7 spacecraft to be ready to meet all of our mission requirements. The first generation has some residual capability, (but) TDRS-M is so critical," said Badri Younes, deputy associate administrator for Space Communications and Navigation at NASA Headquarters.

A successful TDRS-M extends the projected life of the constellation to the mid-2020s.

While TDRS got its start by supporting space shuttle missions, today's network is even busier with the space station that's been continuously staffed for nearly 17 years.

"The thing we saw during the shuttle era was that when a shuttle would go up on a mission, the load on the TDRS system was extremely high. But once it landed that spike in the load would dissipate. We would see the spikes mission by mission," Littmann said.

"What we see today is a little different because those spikes are no longer there, but with the space station being in continuous coverage wh ere we have astronauts 24/7 in orbit. TDRS serves the human spaceflight community in that manner, the comm to the space station is more continuous.

"The spikes have changed to a continuous level to support the International Space Station activities, as well as TDRS developed additional capabilities over the years that it now tracks and provides telemetry for various launch vehicles. That's been added to the mix. The overall usage has remained."

The Atlas 5 rocket that launched TDRS-M, for example, used the constellation's K and L satellites to relay data back to the Cape this morning. Delta 2 and Delta 4 rockets and Orbital ATK's Minotaur 4 rely on TDRS too.

TDRS-M completes the third generation of spacecraft constructed for the Tracking and Data Relay Satellite System as we know it today. What comes next is being debated, including possibilities of a "technology refresh" by adding laser communications to the follow-on program.

However, there is no rush to field the next era of relay satellites. The current TDRS fleet is expected to operate well into the next decade.

Only two of the six shuttle-launched TDRS satellites have been retired, the rest are functional more than 25 years since their deployment and outliving their design lives by exceptional margins.

"Just because the 15 years comes to end doesn't mean we stop operating the spacecraft. Like your electronics or laptop at home, you use it until it doesn't work anymore," said Paul Buchanan, TDRS deputy project manager.

For NASA's Launch Services Program, the team has seven high-profile launches scheduled over the next year, including missions to Mars and the Sun, two weather satellites and a planet-hunter.
-Delta 2/JPSS-1 is NET Nov. 9 at 2:48 a.m. local from Vandenberg
-Pegasus/ICON is Nov. 14 at 10:28 a.m. Eastern from Kwajalein
-Atlas 5/GOES-S is March 1 at 5:01 a.m. at Cape
-Falcon/TESS is NET March 20 at Cape
-Atlas 5/InSight is May 5 at 4:10 a.m. local from Vandenberg
-Delta 4-Heavy/Parker Solar Probe is July 31 at 10:07 a.m. at Cape
-Delta 2/IceSat-2 is Sept. 12 at 5:45 a.m. local from Vandenberg

The next two United Launch Launch Alliance Atlas 5 flights will deploy critical-but-classified security payloads for the U.S. National Reconnaissance Office.

NROL-42 will fly from Vandenberg Air Force Base in California using a powerful 541-configured rocket with four side-mounted solid-fuel boosters and NROL-52 occurs from Cape Canaveral on a 421 with two solids.

The constellation of satellites charged with maintaining critical communications between NASA's Space Network and Earth-orbiting spacecraft is about to be expanded by one.

Joining the Tracking and Data Relay Satellite (TDRS) System is TDRS-M, the third and final in a series of third-generation TDRS spacecraft that have taken their places in orbit in recent years. TDRS-M launched this morning aboard a United Launch Alliance (ULA) Atlas V rocket with a liftoff at 8:29 a.m. EDT from Cape Canaveral Air Force Station's Space Launch Complex 41.

With light winds, few clouds and temperatures in the low 80s, weather posed no threat to launch. The countdown proceeded smoothly throughout the early morning hours and into propellant-loading operations, when engineers noted an issue with the Centaur upper stage's liquid oxygen (LOX) chilldown system.

"As we were chilling the Centaur engine down, we noticed one of the chilldown parameters on the thermal conditioning for the LOX side was not quite getting cold enough" in time to permit liftoff at 8:03 a.m., when the 40-minute launch window opened, NASA Launch Manager Tim Dunn explained.

The team methodically worked to resolve the issue while maximizing that window of opportunity, and the issue was resolved in time for launch officials to set up for a successful liftoff at 8:29 a.m.

TDRS-M's predecessors, TDRS-K and TDRS-L, also launched on Atlas V rockets from the same launch complex in January 2013 and January 2014, respectively. Today's launch marked the 72nd liftoff of an Atlas V.

More than an hour and a half after launch, the TDRS-M spacecraft separated from the rocket's Centaur upper stage, heralding the end of the launch effort and the mission's beginning. Following several months of calibration and testing, TDRS-M will be renamed TDRS-13, and it will be eligible to begin supporting NASA's Space Network.

"Spacecraft separation is the best part of the launch campaign," Dunn said. "So many hours are put into getting to this exact point when you know you have a healthy satellite that just separated from the launch vehicle, about to go do its intended mission."

CAPE CANAVERAL — NASA's new communications satellite, launched to a preliminary orbit August 18, has ascended to geosynchronous altitude more than 22,000 miles up, deployed its giant antennas and extended twin solar arrays to begin in-space commissioning.

https://www.youtube.com/watch?v=T-JI70F0-DE (https://www.youtube.com/watch?v=T-JI70F0-DE)
The $408 million Tracking and Data Relay satellite-M, was successfully lofted to a high-perigee geosynchronous transfer orbit by United Launch Alliance's Atlas 5 rocket from Cape Canaveral less than two weeks ago.

It then performed a series of orbit-raising maneuvers with its 100-pound thrust engine that boosted its highly elliptical orbit — roughly 2,888 statute miles at its closest approach to Earth to 22,230 statute miles at apogee with 26.1 degrees inclination — to a circular orbit.

The burns systematically raised the perigee to:
 – 6,568 miles at 17.6 degrees
 – 13,679 miles at 10.6 degrees
 – 19,918 miles at 7.7 degrees
 – 21,934 miles at 7.2 degrees
 – 22,204 miles at 7.1 degrees

After reaching a good orbit Monday, the craft spent Tuesday extending its power-generating solar panels that had been stowed against the satellite's main body for launch. TDRS-M now has a wingspan of 69 feet tip-to-tip.

Also, the booms holding the two 15-foot-diameter graphite composite mesh antennas were unfolded and the Space-to-Ground Link antenna was unlocked and re-positioned for use.

The current orbital slot is 150 degrees West longitude, over the Pacific, for checkout. Control of the satellite is being handed from Boeing's facilities in California to NASA's White Sands Complex in New Mexico for the start of on-orbit testing.

Commissioning will continue through January by Boeing engineers to demonstrate the spacecraft is functioning properly before NASA accepts ownership.
 
TDRS-M is the 12th and final Tracking and Data Relay satellite of the current era to be launched since 1983. Its addition to the existing 7-satellite constellation will ensure the system's viability into the mid-2020s at least.

TDRS provides constant communications between Earth-orbiting spacecraft and ground controllers, supporting round-the-clock operations of the International Space Station, plus data relay functions from the Hubble Space Telescope and nearly 40 scientific observatories.

NASA's TDRS-M satellite this week reached its high-altitude perch in Geosynchronous Orbit and completed all major deployment events on its solar arrays and antennas in preparation for a multi-month commissioning phase before entering an active role within the agency's Tracking and Data Relay Satellite System.

TDRS-M is the 13th TDRSS satellite to reach orbit and the third and final in the program's third generation that offers greater capacity than its predecessors to respond to growing communication demands, supporting 40+ NASA missions as well as other government satellites, commercial launch vehicles and airborne assets.

The 3,500-Kilogram satellite took flight at 12:29 UTC on Friday, August 18 atop an Atlas V 401 rocket blasting off fr om Cape Canaveral Air Force Station.

TDRS-M received a smooth ride atop the Atlas V workhorse that checked off its 72nd mission success – firing its RD-180-powered first stage for four minutes before the trusted Centaur upper stage took over for a customized two-burn mission design with a long 13.5-minute first burn into an initial orbit peaking 25,700 Kilometers in altitude followed by one and a half hours of passive flight to gain altitude ahead of a 56-second engine re-light to boost TDRS-M into its intended Geosynchronous Transfer Orbit.

Setting out on its mission, TDRS-M checked in with ground stations for a series of health checks that confirmed the Boeing-built satellite had arrived in orbit in excellent condition and was ready for its climb from an elliptical transfer orbit up to its operating post 35,800 Kilometers above the planet.

Tracking data provided by the Joint Space Operations Center showed the satellite in an initial orbit of 4,647 by 35,753 Kilometers at an inclination of 26.21°. Before starting its climb, the satellite freed up its two-large mesh antennas to take their parabolic shape while still remaining in the stowed configuration on the forward-facing side of the satellite.

Within three days of launch, TDRS-M had completed the first firing of its R-4D apogee engine, lifting the low point of the orbit to 10,560 Kilometers and shaving nine degrees off its orbital inclination.

The next apogee maneuver raised the orbit's low point to 22,000 Kilometers and decreased the inclination to 10.6 degrees and was followed by another firing that brought the perigee to 32,050 Kilometers and further reduced the inclination to 7.7 degrees. Another main engine firing placed the satellite in a 35,290 by 35,786-Kilometer orbit, inclined 7.11 degrees – leaving only some fine-tuning to be completed to reach a synchronous orbit in tune with Earth's rotation.

NASA announced on Monday that TDRS-M had achieved its planned GSO location and tracking data showed it in an orbit of 35,776 by 35,802 Kilometers, 7.0° at a position of 149.5 degrees west.

Having arrived in its planned checkout location, the 8.14-meter tall satellite began a complex deployment sequence. TDRS-M successfully deployed one of its 7.6-meter long solar arrays followed by the two 4.6-meter diameter single-access antennas each of which will be tasked with tracking a lower-orbiting spacecraft to provide a high-speed link in S/Ku/Ka-Band to relay vast amounts of data to the respective mission control centers. Afterwards, the satellite deployed its second solar array, the 1.9-meter Space-to-Ground Link Antenna and the omni-S-Band antenna that carries telemetry and commands for the TDRS satellite itself. All deployments went by the book, NASA reported, allowing TDRS-M to head into its four-to-five-month commissioning phase.

When commissioning is complete and the satellite is ready for service, it will be re-named TDRS-13 and drift into its initial operational location over the Atlantic coverage area to provide expansion capacity and TDRSS service extension through the 2020s to ensure the system can remain at full capacity through the International Space Station's planned lifetime.

TDRSS functions by deploying a series of communication relay satellites in three locations in Geostationary Orbit, over the Atlantic (TDRS-East), Pacific (TDRS-West) and TDRS-Z over the Indian Ocean, covering what is known as the Zone of Exclusion – a small blind area between the eastern and western satellites. Featuring different antennas, the satellites relay data from lower-orbiting spacecraft to ground terminals in Guam and New Mexico from wh ere data is routed to the respective users.

The most prominent user of TDRSS is the International Space Station, using high-rate communications to beam down a plethora of video and data feeds from dozens of scientific experiments on the inside and outside of the complex while low-rate communication links are used to provide a near-continuous voice link between Mission Control and the crew. TDRS also provides standard-of-living services for the crew like video-conferencing with their families, TV uplink and Internet access, using TDRS as a relay from the ground to a LEO spacecraft.

Beyond ISS, TDRSS supports other NASA flagship missions like the Hubble Space Telescope and the Landsat program that has kept watch over Planet Earth for over four decades. All in all, TDRSS is relied on by dozens of NASA missions and other users like the Department of Defence to keep in contact with some of its classified space assets.

TDRSS offers single-access services for data-intensive missions and a phased array on the satellite's Earth-facing side will provide multi-access links to several spacecraft at the same time. Each single-access antenna supports one spacecraft at a time, typically the ISS (when in view) and one other craft – used for high-data rate burst downlink of stored onboard data.

Single-access services are available in three bands – Ku/Ka-Band is employed for very high data rates up to 800 Mbit/s for the return link and S-Band rates can be as high as 25 Mbit/s. Multi-access allows each TDRSS satellite to receive and send data to up to five other satellites at the same time.

NASA has begun operating the last satellite of its kind in the network that provides communications and tracking services to more than 40 NASA missions, including critical, real-time communication with the International Space Station (http://www.nasa.gov/station). Following its August launch (https://www.nasa.gov/press-release/nasa-successfully-launches-latest-communications-satellite) and a five-month period of in-orbit testing, the third-generation Tracking and Data Relay Satellite (TDRS), referred to as TDRS-M until this important milestone, was renamed TDRS-13, becoming the tenth operational satellite in the geosynchronous, space-based fleet.

"With TDRS-13's successful acceptance into the network, the fleet is fully replenished and set to continue carrying out its important mission through the mid-2020s," said Badri Younes, NASA's deputy associate administrator for Space Communications and Navigation at NASA Headquarters in Washington. "Now, we have begun focusing on the next generation of near-Earth communications relay capabilities."

The 10 TDRS spacecraft comprise the space-based portion of the Space Network (https://www.nasa.gov/directorates/heo/scan/services/networks/sn), relaying signals from low-Earth-orbiting missions with nearly 100 percent coverage.

"The acceptance of this final third-generation TDRS into the Space Network is the result of many years of dedication and hard work by the TDRS team," said Dave Littmann, the TDRS project manager at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "As a result, critical space communication and tracking services that enable NASA human spaceflight and scientific discovery will continue well into the next decade."

​TDRS-13 launched on Aug. 18, 2017, aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida. Built by Boeing in El Segundo, California, TDRS-13 and its nearly identical third-generation sister spacecraft are performing well. TDRS-K and -L launched in 2013 and 2014, respectively.

NASA established the TDRS project in 1973, and the first satellite launched 10 years later, providing NASA an exponential increase in data rates and contact time communicating with the space shuttle and other orbiting spacecraft, such as the Hubble Space Telescope. Since then, NASA has continued to expand the TDRS constellation and advance the spacecraft capabilities.

"NASA looks forward to the future, developing even better ways to meet missions' communications needs," said Younes. "We will leverage NASA's success in optical communications and other innovative technologies, as well as significantly increase our partnership with industry, as we envision a shift to increased reliance on commercial networks for most, if not all, of our communications needs in the near-Earth environment."

Goddard is home to the TDRS project, which is responsible for the development and launch of these communication satellites. Boeing, headquartered in Chicago, Illinois, is the private contractor for the third-generation TDRS spacecraft. TDRS is the space element of NASA's Space Network, providing the critical communication and navigation lifeline for NASA missions. NASA's Space Communications and Navigation (SCaN) program, part of the Human Exploration and Operations Mission Directorate at the agency's Headquarters in Washington, is responsible for NASA's Space Network.
