TDRS K [Boeing BSS]
NASA sel ected Boeing in December 2007 to built the next generation of TDRS (Tracking & Data Relay Satellite) data relay satellites. The TDRS-K satellite will be ready for launch in 2012, and TDRS-L will be ready for launch in 2013.
This contract includes the design and manufacturing of the TDRS-K series satellites as well as upgrades to NASA's TDRS system ground terminals.
The satellites incorporate a modern design based on flight-proven performance. The three previous TDRS satellites were based on Boeing 702-class electronics, which are still the standard for the newest spacecraft Boeing is building today. Additionally, Boeing has modernized the technologies in the payload, power and propulsion subsystems to current state-of-the-art technologies being used in other Boeing-built spacecraft.
A pair of 15-foot-diameter, flexible mesh antenna reflectors fold up for launch, then spring back into their original cupped circular shape on orbit. These steerable, single-access antennas can simultaneously transmit and receive at S-band and either Ku- or Ka-band, supporting dual independent two-way communication. The selection of Ku- or Ka-band communications is done on the ground.
In addition, an S-band phased array antenna can receive signals fr om several spacecraft at once, while transmitting to one.
Two more satellites are currently planned. The option for the third satellite, TDRS-M, was exercised in November 2011.

Countdown to TDRS-K Launch: December 6, 2012ЦитироватьThe TDRS Project is building three space communications satellites that are part of a follow-on spacecraft fleet that will replenish NASA's Space Network. The TDRS Project Office at Goddard Space Flight Center manages the TDRS development effort. TDRS is the responsibility of the Space Communications and Navigation (SCaN) office within the Human Exploration and Operations (HEO) Mission Directorate at NASA Headquarters in Washington D.C. Operations of the network is the responsibility of the Space Network Project at Goddard.
In December 2007, NASA signed a contract for Boeing Space Systems to build two, third generation TDRS spacecraft for launch in 2012 and 2013. An option for a third TDRS spacecraft was executed in 2011. Within the contract were the required modifications that will enable the White Sands Complex ground system to support the new spacecraft.
The December 2012 launch of TDRS-K will begin the replenishment of the fleet through the development and deployment of the next generation spacecraft. These satellites will ensure NASA's Space Network continues to provide around-the-clock, high throughput communications services to NASA's missions and serving the scientific community and human spaceflight program for years to come.

SPACEFLIGHT NOW
Posted: January 3, 2013
Cape Canaveral's 2013 launch season began taking shape today as technicians started assembling the Atlas 5 rocket for the year's first Space Coast mission -- delivery of a NASA communications satellite into orbit on Jan. 29.

The United Launch Alliance-made rocket will haul the Tracking and Data Relay Satellite K (TDRS K) to space to reinforce NASA's communications network that routes voice calls, telemetry streams and television signals fr om the International Space Station, as well as science information from the Hubble Space Telescope and other orbiting spacecraft.
Liftoff is targeted for Jan. 29 during a 40-minute launch window opening at 8:52 p.m. EST (0152 GMT) from the Cape's Complex 41.
Putting the two-stage rocket together got underway this morning as ULA workers brought the bronze-colored first stage to the Vertical Integration Facility for stacking operations.
By late morning, the booster was secured aboard its mobile launcher, anchored on small supports that protrude from the platform. At liftoff, explosive bolts free the rocket and those supports will retract into the platform walls as the vehicle powers its way off the pad on 860,000 pounds of thrust.
Known as the Common Core Booster, the stage was pulled by a semi-truck up the road from the Atlas Spaceflight Operations Center high bay to the 30-story VIF building wh ere workers attached lifting cranes. The 106.6-foot-long stage was rotated vertical, then maneuvered into the building and stood upright on the mobile platform.
The stage is equipped with a dual-nozzle RD-180 main engine that will burn kerosene fuel and supercold liquid oxygen during the initial minutes of flight.
Upcoming will be installation of the interstage adapter that tappers the 12.5-foot diameter first stage to the 10-foot-wide Centaur upper stage.
The cryogenic upper stage will be hoisted atop the interstage tomorrow to complete the basic buildup of the Atlas 5.
Centaur's single RL10 engine, fueled by liquid hydrogen and liquid oxygen, will perform the necessary burns to achieve orbital velocity and then shape the orbit for deployment of TDRS K.
The stage is 41.5 feet in length and also houses the navigation unit that serves as the rocket's guidance brain.
The rocket is known as the 401 configuration of the multi-varient Atlas 5 family, which is tailored with strap-on solid boosters and different sized nose cones to match the cargo's mass and size.
For TDRS K, however, the plain two-stage launcher with no solids will provide ample performance to carry the Boeing-built satellite to orbit.
The spacecraft arrived from the Boeing factory on Dec. 18 and has since undergone preflight electrical testing at the Astrotech processing facility in Titusville. The loading of maneuvering fuel is scheduled for this weekend.
The satellite will be encapsulated in the rocket's nose cone on Jan. 15 in preparation for delivery to the VIF and mounting atop the Centaur on Jan. 17 to finish assembly of the 19-story-tall launcher.
ULA and its customers have opted to delete the countdown dress rehearsals for 401 vehicles at the Cape, condensing the prelaunch timelines for such rockets, except for planetary missions.
Rollout to the launch complex occurs the day before liftoff as the 1.4-million pound platform rides the rail tracks 1,800 feet from the VIF to the pad.
The seven-hour countdown begins at 1:52 p.m. EST on launch day, leading to cryogenic liquid oxygen and liquid hydrogen fueling operations starting at 6:59 p.m. for a planned blastoff at 8:52 p.m. EST, as the launch window opens for the first Atlas launch of the year and the 35th overall since 2002.

Centaur First Main Engine Cutoff
A successful first burn for the Centaur stage ended on time with engine cutoff. Centaur and TDRS-K are in a highly elliptical, 113-by-13,402-mile orbit for this one-hour, 22-minute coast phase. The coast phase ends with the final burn of the Centaur engine to deploy TDRS-K.
The TDRS-K spacecraft will be released from the Centaur into a transfer orbit; it will take another 10 days to reach its proper orbit. It will take another three months, approximately, to test and calibrate the spacecraft. Once it passes an acceptance review, it's ready to move to its preferred location.

MONDAY, FEBRUARY 4, 2013
NASA's newest communications relay satellite, launched fr om Cape Canaveral last Wednesday, has begun maneuvering itself towards geosynchronous orbit over the Pacific Ocean. The Boeing Co. designed and built the Tracking and Data Relay Satellite K for NASA and is controlling the spacecraft during its early days in orbit.
A United Launch Alliance Atlas 5 rocket carried TDRS K into a geosynchronous transfer orbit, an elliptical type of orbit that is the customary drop off point for spacecraft bound for a parking spot about 22,300 miles above Earth. The launcher released the payload into the preliminary orbit with a high point of 22,245 statute miles, low point of 2,680 statute miles and inclination of 25.6 degrees.
From there, Boeing satellite controllers will reduce the inclination and raise the low point to circularize it into a geosynchronous orbit wh ere TDRS K can match Earth's rotation and appear parked at 150 degrees West longitude, the planned location of in-space testing and checkout.
The first of five firings of the satellite's onboard engine was successfully accomplished on Sunday, said John Leuer, the TDRS K program director at Boeing Space and Intelligence Systems.
"TDRS K is performing well on-orbit," he said.
The satellite stood 26 feet tall and weighed over 7,600 pounds at launch, including 3,700 pounds of maneuvering fuel loaded inside the craft. Once fully deployed in space, TDRS K's solar wings will stretch 69 feet tip-to-tip to generate 3,220 watts of power and charge internal nickel-hydrogen batteries.
The primary physical feature of the satellite is two 15-foot-diameter flexible graphite mesh antenna dishes that were folded like taco shells for launch, then successfully sprung into shape once released in orbit.
"The 15 ft diameter Single Access antenna reflectors are now unfurled," Leuer said.
The antennas offer gimbal tracking of targeted spacecraft flying beneath the satellite, providing high-gain communications to the station, Hubble and other craft for vital contacts and data dumps.
After finishing the orbit-raising activities later this week, the spacecraft's full appendages will be deployed, starting with one solar array, then the booms holding the Single Access antennas fold out, the other solar wing extends, the forward Omni swings into place and the space-to-ground antenna is positioned.
Once the satellite undergoes three months of testing at 150 degrees West, NASA will "take the keys" from Boeing and drift the craft to its operational location at 171 degrees West for the start of a 15-year service life later this spring.
"With this launch, NASA has begun the replenishment of our aging space network," said Jeffrey Gramling, NASA's TDRS project manager. "This addition to our current fleet of seven will provide even greater capabilities to a network that has become key to enabling many of NASA's scientific discoveries."

NASA ACCEPTS THIRD GENERATION TDRS INTO NETWORK
NASA has accepted ownership of its newest Tracking and Data Relay Satellite (TDRS) from Boeing after successfully completing in orbit testing. TDRS-K, will be renamed TDRS-11 upon entry into service.
This is a major step in replenishing an aging TDRS fleet which is essential in providing communications to support space exploration," said Badri Younes, deputy associate administrator for Space Communications and Navigation at NASA Headquarters. "We look forward to the launch of two additional satellites in the next few years to complete the replenishment program."
The TDRS fleet provides communications support to an array of science missions, as well as several launch vehicles. The network has provided critical real-time communication with NASA's human spaceflights since early in the Space Shuttle Program. TDRS network operations continue to provide support for International Space Station activities.
"The acceptance of this spacecraft is the result of many years of hard work by dedicated team members at NASA and Boeing," said Jeffrey Gramling, TDRS project manager at NASA's Goddard Space Flight Center in Greenbelt, Md. "This next generation of spacecraft ensure network continuity for at least another decade."
Goddard is home to the TDRS Project Office, which is responsible for the development and launch of the communication satellites. The Boeing Company headquartered in Chicago, Ill., is the private contractor for the TDRS K, L and M satellites. TDRS is the space element of NASA's Space Network, providing the critical communication lifeline for NASA missions. NASA's Space Communications and Navigation Program, part of the Human Exploration and Operations Mission Directorate at the agency's Headquarters in Washington, is responsible for NASA's Space Network.
The TDRS fleet now consists of eight satellites with ground stations at White Sands, N.M. and Guam. NASA's upgrade to the network includes modifications to those ground terminals.
The TDRS Project was established in 1973 to provide continuous communications to NASA's critical low Earth-orbiting science and human spaceflight missions. When TDRS-1 was launched from space shuttle Challenger in 1983, TDRS spacecraft were the largest, most sophisticated communication satellites ever built. TDRS-1 provided NASA an exponential increase in data rates and contact time communicating with spacecraft.
NASA continued adding TDRS spacecraft (the first seven were built by TRW, later to become Northrop Grumman) until 1995. TDRS-2 was lost during the Challenger accident in 1986. From 2000 to 2002, NASA added three spacecraft to the fleet, establishing the second generation. The H, I, and J, satellites were built by Hughes (later to become Boeing) and continue to operate along with members of the now aging first generation. TDRS-1 was retired in 2010 and TDRS-4 in 2011.
On Jan. 30, TDRS-K was launched aboard an Atlas V rocket from Cape Canaveral Air Force Station in Florida. Before this year's launch it had been 10 years since NASA last added a TDRS to the network. These next-generation satellites are being built at Boeing's Space & Intelligence Systems in El Segundo, Calif.
TDRS-K, L, M, together with the other spacecraft that continue to operate well beyond their design life, will ensure NASA's critical missions will be supported into the 2020's. The launch of TDRS-L is slated for January 2014 and TDRS-M will be ready for launch in December of 2015.
