A powerhouse communications satellite owned by Inmarsat has been fueled for liftoff on a SpaceX Falcon 9 rocket Monday fr om the Kennedy Space Center in Florida on a mission to provide broadband links for passengers and crews aboard ships and airplanes, while ground crews are loading space station-bound supplies into a commercial Dragon cargo capsule and preparing a Bulgarian telecom for launch on two other SpaceX boosters by mid-June.

Спойлер

The launch for London-based Inmarsat on Monday is the first of four SpaceX missions slated to blast off by the end of June fr om launch pads in Florida and California. The quick launch cadence, if achieved successfully, put a dent in SpaceX's backlogged manifest, which officials say stands at 70 missions worth more than $10 billion, figures that apparently include the company's lucrative contract to develop a human-rated spaceship to ferry astronauts to the International Space Station.

Since arriving at the Florida launch base last month, the Boeing-built Inmarsat 5 F4 communications station was filled with 5,372 pounds (2,437 kilograms) of hydrazine and nitrogen tetroxide propellants during a four-day procedure inside SpaceX's payload processing facility at Cape Canaveral.

Technicians lifted the spacecraft on the Falcon 9's payload adapter, made by Ruag Space in Sweden, ahead of encapsulation this week inside the rocket's composite payload fairing.  The adapter is fitted with a ring connecting the Inmarsat 5 F4 spacecraft to the Falcon 9's second stage.

Meanwhile, SpaceX workers inside the Falcon 9 hangar at nearby launch pad 39A were mounting the two-stage booster on a mobile transporter-erector Wednesday. SpaceX intends to roll out the rocket to pad 39A for a customary fueling test and a hold-down engine firing as soon as Thursday.

The Falcon 9's Merlin 1D main engines will ignite for more than three seconds as clamps keep the rocket grounded. Engineers plan to analyze the performance of the rocket before clearing it for liftoff Monday.

After the hotfire test, crews will return the Falcon 9 to the hangar at the southern perimeter of pad 39A, wh ere the Inmarsat 5 F4 satellite and the rocket's nose fairing will be attached. The rocket's final rollout to the historic launch complex, previously used by Saturn 5 moon rockets and space shuttles, is expected Sunday or early Monday.

The 50-minute launch window Monday opens at 7:20 p.m. EDT (2320 GMT).

The heavy weight of Inmarsat 5 F4 — more than 13,000 pounds, or around 6 metric tons — will prevent the Falcon 9 rocket's first stage booster from attempting a landing on SpaceX's recovery vessel in the Atlantic Ocean. The booster is not expected to launch with landing legs, grid fins, or other hardware needed for descent maneuvers.

Inmarsat 5 F4 will deploy into an oval-shaped geostationary transfer orbit, with a low point a few hundred miles above Earth and an apogee tens of thousands of miles in altitude. The craft's on-board hydrazine-fueled engine will circularize its orbit at an altitude of nearly 22,300 miles (around 35,800 kilometers) over the equator.

Monday's launch will be the sixth SpaceX mission this year. The company's founder and chief executive, Elon Musk, said in late March that SpaceX planned between 20 and 25 rocket flights in 2017, aiming to average missions every two weeks or so.

The rapid-fire launch campaigns have long been promised by SpaceX, but two rocket failures in June 2015 and September 2016 grounded the company's missions for months, combining to set back its manifest by nearly one year.

Shorter delays stemming from satellite issues, rocket production bottlenecks, and the difficulty of scheduling launches to the International Space Station have also stricken SpaceX. NASA must weigh the readiness of station astronauts and other missions heading to the orbiting research outpost when approving launch dates for SpaceX's Dragon supply ships.

But SpaceX now has a surplus of customers with payloads ready for launch.

Managers from the launch company's biggest commercial client, Iridium, said last month that half of the firm's 81 next-generation communications satellites have been constructed by Thales Alenia Space and Orbital ATK at a factory in Arizona. The first batch of 10 Iridium Next spacecraft were launched into orbit a few hundred miles above Earth in January on a Falcon 9 rocket, and the rest await Falcon 9 rides into orbit from Vandenberg Air Force Base in California promised by SpaceX every two months beginning June 29.

Intelsat officials said in an April 27 conference call with investors that the Boeing-made Intelsat 35e communications satellite, the fourth in the operator's new-generation "Epic" high-throughput relay satellites, is scheduled for a Falcon 9 launch in late June from Florida.

But first comes three Falcon 9 flights with launches targeted for Monday, June 1 and June 15.

The fourth member of Inmarsat's Global Xpress network, a $1.6 billion, four-satellite update to the operator's geostationary fleet, will add back-up capacity and new business opportunities to the London-based company's constellation following its launch Monday.

Based on the Boeing 702HP satellite bus, Inmarsat 5 F4 joins three nearly identical spacecraft successfully orbited on three Russian Proton rockets from 2013 through 2015 under the auspices of International Launch Services, a U.S.-based, Russian-owned launch services provider.

The first three Inmarsat 5-series satellites are parked in geostationary orbit at positions around the globe. The first Global Xpress satellite is positioned to cover Europe, the Middle East and Africa, the second is over the Atlantic Ocean and the Americas, and a third Inmarsat 5 satellite launched in August 2015 provides coverage to the Asia-Pacific and Australia.

Rupert Pearce, Inmarsat's CEO, said May 4 that Inmarsat 5 F4 will probably begin service over Europe, supplementing the Inmarsat 5 F1 satellite's coverage there.

Pearce said there is a "strong business case" for locating the new satellite over Europe, but he said Inmarsat has not solidified its plan for Inmarsat 5 F4.

"Because it's not needed (for) complete global coverage, the role of Inmarsat 5 F4 could change through its life," said Tony Bates, Inmarsat's chief financial officer, in a May 4 quarterly conference call with investment analysts. "And obviously, they are for in-orbit redundancy, which would lim it it if it was needed for that purpose. But otherwise, it can go off to discrete business opportunities that may differ during its life."

The major customers for the Global Xpress network — Inmarsat's fifth-generation fleet — include airlines, which use satellite links for safety and passenger entertainment, the maritime industry, oil and gas platforms, media companies, and the military.

Boeing is responsible for selling Global Xpress services to U.S. government and military users.

Each Inmarsat 5-series satellite carries 89 fixed and steerable spot beams in Ka-band. The company's earlier satellites broadcast in L-band, but Inmarsat switched to Ka-band for the Global Xpress system, offering improved downlink communications speeds to 50 megabits per second, with up to 5 megabits per second on the uplink side.

Inmarsat 5 F4 was originally supposed to launch in 2016 on a SpaceX Falcon Heavy rocket, a triple-core booster formed by three Falcon 9 first stages. But the heavy-lifter still has not flown, and Inmarsat transferred the Inmarsat 5 F4 launch to a smaller Falcon 9, forcing SpaceX to forego recovery of the first stage booster on the coming flight in order to lift the Global Xpress satellite into orbit.

The Falcon 9 has been hoisted vertical at launch complex 39A at the Kennedy Space Center in readiness for a test of its nine Merlin first-stage engines. The rocket was in position at approximately 5am EDT (0900 GMT).

SpaceX has not released a time for today's static fire test at pad 39A, but loading of the two-stage Falcon 9 with super-chilled RP-1 and liquid oxygen propellants should begin at about T-minus 70 minutes.

Venting of oxygen vapors should be visible around the rocket in the final hour before ignition, and the strongback support structure next to the Falcon 9 will retract 1.5 degrees from the vehicle in the final few minutes of the countdown.

ЦитироватьFalcon 9 readies for Static Fire test ahead of Inmarsat 5 F4 mission
May 11, 2017 by Chris Gebhardt

SpaceX is set to demonstrate for a second time just how short a turnaround it can accomplish at LC-39A with Thursday's planned static fire of the Falcon 9 that is set to launch the Inmarsat 5 F4 satellite Monday afternoon.  As preparations for that mission continue, the flight two slots down on the manifest, the mid-June launch of BulgariaSat 1, has now been announced and confirmed as the next mission to make use of a flight-proven Falcon 9 core stage.
 
Inmarsat 5 F4 static fire:

Coming an impressive 10 days after the launch of the NROL-76 mission for the National Reconnaissance Office (https://www.nasaspaceflight.com/2017/04/spacex-falcon-9-first-nro-mission-nrol-76/), SpaceX is set to bring fire to LC-39A again for the static fire of the Inmarsat 5 launch campaign.

Спойлер

(https://img.novosti-kosmonavtiki.ru/209120.jpg)

The static fire will tie the shortest turnaround the pad has seen for SpaceX at just 10 days between a launch and a static fire (https://www.nasaspaceflight.com/2017/05/spacex-launch-cadence-new-goals/), with an anticipated – and only once seen before – 14 days between two launches.

That record was set with the 14 day turnaround at SLC-40 in September 2014 – between the AsiaSat 6 launch on the 7th and the CRS-4 mission on the 21st.

Documentation in L2 shows that the time between Echostar XXIII and SES-10 could have been even shorter, at just 12 days fr om launch to launch; however, range shuffling with the continuously-delayed Atlas V for the Orbital ATK OA-7 (https://www.nasaspaceflight.com/2017/04/atlas-v-oa-7-cygnus-launch-iss/) mission pushed SES-10 out of its range approved 27 March date, with the launch eventually falling on 30 March.
 
After SES-10 (https://www.nasaspaceflight.com/2017/03/spacex-historic-falcon-9-re-flight-ses-10/), a two week delayed due to the NRO's secretive payload precluded SpaceX from repeating its rapid turnaround efforts with the NROL-76 mission, though it is understood and documented in L2 that Pad-A and the TEL (Transporter/Erector/Launcher) were ready to support the NRO launch in its original mid-April slot (https://www.nasaspaceflight.com/?s=LC-39A).

Importantly for SpaceX, this soon-to-be repeated two week turnaround between missions is crucial to launching the myriad of satellites currently in the company's full manifest.

Pointedly, the ability for SpaceX to perform this kind of short turnaround is due in large part to a change in the TEL retract sequence that occurs at T0.

(https://img.novosti-kosmonavtiki.ru/209171.png)

At SpaceX's other launch pad, SLC-40 at the Cape Canaveral Air Force Station, the TEL retracted slowly from the Falcon 9 at T0, resulting in damage to several of the TEL umbilicals from the Falcon 9's exhaust plume that necessitated timely replacement and repair operations between missions.

For Pad-A, SpaceX adopted a new "throwback" procedure for the TEL, which quickly moves it away from the rising Falcon 9 to protect its umbilicals (https://www.nasaspaceflight.com/2017/01/dragon-pulls-rank-lc-39a-readiness-spacex/).

This "throwback" procedure has been praised by the company as immensely successful in eliminating the timely turnaround efforts needed for the TEL between missions – as is now being fully re-demonstrated with the 10 day period between the NROL launch and Inmarsat 5's static fire.

(https://img.novosti-kosmonavtiki.ru/209172.png)

For Inmarsat 5, the Falcon 9 rocket and its mated second stage will be rolled to the launch pad and hoisted to vertical on Wednesday afternoon, after which final connections to Pad 39A's propellant, electrical, and data systems will be made.

As with Echostar XXIII, the Inmarsat 5 Falcon 9 is expected to look slightly different than what we have come to know as the traditional Falcon 9.

Inmarsat 5's mission profile denotes the need to fly the Falcon 9 in its expendable configuration and the vehicle will therefore not sport any landing legs and will not attempt an ocean landing on the ASDS (Autonomous Spaceport Drone Ship) Of Course I Still Love You (https://www.nasaspaceflight.com/?s=Of+Course+I+Still+Love+You).

(https://img.novosti-kosmonavtiki.ru/209060.png)

As with standard static fire procedures, roadblocks and Emergency Operations Command (EOC) will be established to prevent access to Pad 39A and to assist with recovery efforts in the unlikely event of a static fire mishap.

As with the previous static fires (https://www.nasaspaceflight.com/?s=static+fire) from Echostar XXIII through NROL-76, Pad 39B will remain open to workers at the Kennedy Space Center during the static fire.

While a specific window for Thursday's static fire is not yet known, the event is understood to be targeting an 0800 to 1200 EDT window – though as with previous static fires, that window can be adjusted day of.

For the static fire, the Falcon 9's first and second stages will be completely filled with propellant as the launch team conducts what is essentially a full-up Wet Dress Rehearsal practice countdown, going through every step and procedure that will be used on launch day.

(https://img.novosti-kosmonavtiki.ru/209160.jpg)

When the count reaches T-3 seconds, the "start" command for the nine Merlin 1D engines at the base of the Falcon 9 first stage will be sent, with chamber ignition occurring at T-2 seconds.

The Falcon 9 engines will then run for three seconds, as is standard for static fires, before engine shutdown is commanded and safing of the vehicle occurs.

The engine firing and shutdown sequence not only allows SpaceX to gather valuable data about the entire rocket's performance – guaranteeing it is ready for liftoff – but also gives the launch team the opportunity to practice shutdown and safing operations of the Falcon 9 should that occur during the actual countdown.

Following static fire, the Falcon 9 will be de-tanked, returned to horizontal, and rolled back into the Horizontal Integration Facility (HIF) at Pad-A (https://www.nasaspaceflight.com/?s=HIF) wh ere it will then be mated with its Inmarsat 5 F4 payload.

At this time, liftoff is slated to occur on Monday, 15 May 2017 during a launch window of 1920 – 2010 EDT (2310 – 0010 GMT – Monday into Tuesday).

Ten days after the last liftoff fr om historic launch pad 39A in Florida, another SpaceX Falcon 9 rocket ignited its Merlin main engines for several seconds in a hold-down firing Thursday ahead of a planned expendable flight next week with an Inmarsat communications satellite.

The two-stage rocket was filled with super-chilled, densified RP-1 kerosene and liquid oxygen propellants in a mock countdown Thursday. SpaceX engineers monitored the computer-controlled countdown as the rocket's engines were primed and fuel tanks pressurized for ignition.

Nine Merlin 1D engines fired for around three seconds at 1645 GMT (12:45 p.m. EDT) as clamps restrained the launcher at pad 39A. A plume of exhaust rushed out the flame trench to the north of the seaside facility at NASA's Kennedy Space Center.

SpaceX was expected to confirm on Twitter that the customary preflight test, called a static fire, was successfully accomplished. Engineers will look at data on the performance of the engines before convening a launch readiness review ahead of a planned blastoff Monday evening.

Спойлер

The next step in the launch campaign will be the removal and rollback of the Falcon 9 rocket to SpaceX's hangar about a quarter-mile to the south of pad 39A. The structure is built on top of the crawlerway wh ere Saturn 5 moon rockets and space shuttles traveled before climbing into orbit.

The Inmarsat 5 F4 satellite, a Boeing-built craft designed to link airplanes and ships via broadband, inside SpaceX's payload fairing will be rotated on its side and connected with the Falcon 9 inside the hangar this weekend.

Owned by London-based Inmarsat, the satellite will join a fleet of three other relay platforms in geostationary orbit providing global broadband connectivity to airliners, business jets, maritime vessels, oil and gas industry users, and military units.

Inmarsat ordered the satellite from Boeing in 2014 as a spare for the Global Xpress network. At the time, Inmarsat projected Inmarsat 5 F4 to cost between $220 million and $250 million.

After a check of the mechanical and electrical interfaces between the launcher and the Inmarsat 5 F4 satellite, SpaceX ground crews will transfer the Falcon 9 horizontally back up the ramp to pad 39A on Sunday or early Monday. Hydraulic pistons will hoist the 229-foot-tall (70-meter) rocket vertical for Monday's countdown.

The launch window Monday opens at 7:20 p.m. EDT (2320 GMT) and extends for 50 minutes. The Falcon 9 will head east from the Cape Canaveral spaceport to place the Inmarsat satellite into an elliptical geostationary transfer orbit with reaching tens of thousands of miles above Earth.

Inmarsat 5 F4's on-board thrusters will guide the satellite to a perch in circular orbit around 22,300 miles (35,800 kilometers) over the equator.

The upcoming mission will be the sixth SpaceX launch of the year, and the fifth Falcon 9 flight from pad 39A since Feb. 19. It will mark the 99th liftoff from the storied launch complex, which entered service in the Apollo era and hosted the majority of space shuttle launches, including the first and last departures of NASA's winged spaceships.

Monday's launch will be the 34th flight of a Falcon 9 rocket overall since SpaceX's commercially-developed booster debuted in June 2010.

The most recent Falcon 9 mission lifted off from pad 39A on May 1 with a top secret payload for the National Reconnaissance Office, the U.S. government's secretive spy satellite agency.

The official weather outlook issued this morning by the U.S. Air Force indicates an 80 percent chance of favorable conditions during Monday evening's launch window.

"Winds will remain onshore Monday, pushing most sea breeze cumulus clouds inland," meteorologists at the Air Force's 45th Weather Squadron wrote in today's forecast. "There is a slight chance of afternoon storms near Florida's Big Bend, which could shed anvil cirrus back over towards the Space Coast.

"The primary weather concerns are cumulus clouds associated with onshore flow and anvil clouds from inland storms. Maximum upper-level winds will be from the west-northwest at 55 knots near 45,000 feet."

Conditions at launch time are predicted to by mostly sunny with isolated rain showers, with a few clouds at 2,500 feet and scattered clouds at 25,000 feet. Winds should be from the east at 12 to 17 mph, and temperature at launch time will be around 77 degrees Fahrenheit.

Monday's launch window opens at 7:20:46 p.m. EDT (2320:46 GMT) and extends for 50 minutes.

The Boeing-made Inmarsat 5 F4 communications craft... will launch from NASA's Kennedy Space Center aboard a 229-foot-tall (70-meter) Falcon 9 booster at 2321 GMT (7:21 p.m. EDT) Monday, the opening of a 49-minute launch window.

Спойлер

...

SpaceX's launch conductor will poll the launch team at 2208 GMT (6:08 p.m. EDT) for a "go" to begin loading super-chilled, densified propellant into the Falcon 9 rocket. RP-1 kerosene should be pumped into the Falcon 9 beginning at 2211 GMT (6:11 p.m. EDT), followed by cryogenic liquid oxygen at 2236 GMT (6:36 p.m. EDT).

The propellants will continue flowing into the rocket until the final few minutes of the countdown, when the Falcon 9 will switch to internal battery power and its tanks will be pressurized for liftoff.

The Falcon 9's computers will command nine Merlin 1D engines to ignite at the base of the rocket at T-minus 3 seconds. Following an automated health check, the launcher will climb away from pad 39A with 1.7 million pounds of thrust, veering to the east over the Atlantic Ocean.

...

The Falcon 9's first stage engines will fire until T+plus 2 minutes, 45 seconds, and then the 14-story booster will fall away from the rocket's upper stage around four seconds later. A single Merlin 1D engine, fitted with an enlarged nozzle for better efficiency in the airless vacuum of space, will start up at T+plus 2 minutes, 56 seconds, delivering 210,000 pounds of thrust for nearly six minutes to steer into a preliminary orbit.

The rocket's nose cone, a composite fairing that shields the satellite during the first few phase of flight, will drop away from the Falcon 9 during the second stage burn at T+plus 3 minutes, 35 seconds.

After shutdown of the second stage engine, the rocket and the attached Inmarsat 5 F4 satellite will speed across the Atlantic Ocean, flying over Cape Verde before firing its engine again near the equator at T+plus 26 minutes, 59 seconds.

Franci said the 56-second engine firing is designed to push the telecom payload into a "supersynchronous" transfer orbit, with an apogee, or high point, above the satellite's 22,300-mile-high (35,800-kilometer) final operating position.

Parameters for the target orbit are not available, he said, because the upper stage engine is programmed to keep firing until it is almost out of fuel, a technique rocket engineers call a "minimum residual shutdown." The tank-draining burn is intended to ensure the Inmarsat 5 F4 satellite goes into as high of an orbit as possible, reducing the work the craft's own thrusters need to do in the coming months.

Deployment of the satellite from the Falcon 9's upper stage is scheduled for T+plus 31 minutes, 48 seconds.

Around a half-dozen orbit-adjustment firings by the satellite's hydrazine-fueled thruster are planned in the first couple of weeks after launch, followed by the extension of Inmarsat 5 F4's solar panels May 28 to a wingspan of 133 feet — more than 40 meters — wider than the wingspan of a Boeing 737 passenger jet, Franci said.

Then the satellite's xenon-ion maneuvering jets will take over to fine-tune its path around Earth, settling in a circular orbit directly over Earth's equator by mid-August. If the Falcon 9 can boost the craft into a higher-than-expected orbit, several weeks could be shaved off the orbit-raising schedule, according to Franci.

...

Inmarsat 5 F4 should be operational around the end of this year, and its first job will likely be to grow Inmarsat's broadband network load over Europe, the Middle East, North Africa and the Indian subcontinent, Franci said.

ЦитироватьFalcon 9 launch timeline with Inmarsat 5 F4
 May 14, 2017 (https://spaceflightnow.com/2017/05/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

SpaceX's Falcon 9 rocket is set for liftoff from Cape Canaveral early Thursday, heading due east over the Atlantic Ocean to deliver the Inmarsat 5 F4 communications satellite into orbit 32 minutes later.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 39A at NASA's Kennedy Space Center in Florida at 7:21 p.m. EDT (2321 GMT) Thursday at the opening of a 49-minute launch window.

Спойлер

Perched atop the rocket is the Inmarsat 5 F4 communications satellite, a spacecraft made by Boeing, ready to join Inmarsat's Global Xpress network providing broadband connectivity to airline passengers and maritime crews. The rocket will place the satellite into a high-altitude "supersynchronous" transfer orbit.

The timeline below outlines the launch sequence for the Falcon 9 flight with Inmarsat 5 F4. On this mission, SpaceX does not plan to attempt a recovery of the rocket's first stage booster due to the high performance required to place the heavy Inmarsat 5 F4 spacecraft into a high-altitude orbit.

The Falcon 9 does not carry landing legs or grid fins, which are not required for the expendable mission.

The official U.S. Air Force launch weather forecast has improved, now indicating a 90 percent chance of acceptable conditions for liftoff this evening.

The concern with anvil clouds blowing east over Kennedy Space Center from inland thunderstorms has diminished, and forecasters will primarily be monitoring cumulus clouds coming onshore from the Atlantic Ocean.

"Sunny skies and northeasterly surface winds are making for a pleasant day in Central Florida," forecasters wrote. "Winds will become more easterly and pick up a bit over the Space Coast as the sea breeze gets going this afternoon. The sea breeze cumulus clouds will remain mostly shallow due to dry air aloft over the spaceport.

"The primary concern for launch today is a rogue, deeper cumulus cloud associated with onshore flow. Max upper-level winds will be from the west at 55 knots near 45,000 feet."

At launch time, the outlook calls for a few clouds at 2,500 feet, easterly winds of 15 to 20 mph, and a temperature of around 77 degrees Fahrenheit.

ЦитироватьPhotos: Falcon 9 rocket, fourth Inmarsat 5-series satellite prepared for launch
May 15, 2017 (https://spaceflightnow.com/2017/05/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Engineers fr om SpaceX, Boeing and Inmarsat spent the last few weeks preparing a Falcon 9 rocket and the Inmarsat 5 F4 communications satellite for liftoff from NASA's Kennedy Space Center in Florida.

Спойлер

Since the satellite arrived at Cape Canaveral from its Boeing factory in Southern California last month, technicians filled it with 5,372 pounds (2,437 kilograms) of hydrazine and nitrogen tetroxide propellants, fastened it inside the nose fairing of a Falcon 9 rocket, and transferred the spacecraft to SpaceX's nearby hangar, wh ere it was rotated on its side for attachment to the Falcon 9 second stage.

The 13,417-pound (6,086-kilogram) Inmarsat 5 F4 spacecraft is the heaviest commercial telecom satellite launched by SpaceX to date. Based on the Boeing 702HP spacecraft design, the satellite will head into orbit on a 15-year mission to expand broadband coverage for mobile users of Inmarsat's Ka-band Global Xpress service.

It is the fourth satellite to join the Global Xpress network in geostationary orbit and will serve alongside three nearly identical spacecraft already in space after deployments by Russian Proton/Breeze M rockets from 2013 through 2015.

These photos show the spacecraft being attached to its payload attach fitting, made by Ruag Space in Sweden, followed be encapsulation inside the Falcon 9's 17-foot (5.2-meter) diameter payload fairing. Other images show the rollout of the fully-assembled launcher to pad 39A at Kennedy Space Center, and views of the Falcon 9 vertical at the seaside complex on the morning of liftoff.

Monday's launch window opens at 7:21 p.m. EDT (2321 GMT) and extends for 49 minutes.

The Falcon 9's second stage engine is expected to ignite at T+plus 26 minutes, 59 seconds, and burn for around 56 seconds. The engine is programmed to burn until the upper stage tanks have little propellant left in them, a tank-draining technique called "minimum residual shutdown."
Such a maneuver is intended to give the Inmarsat 5 F4 satellite the biggest boost possible into a high-altitude supersynchronous transfer orbit.

ВАШИНГТОН, 16 мая – РИА Новости. Ракета-носитель Falcon 9 стартовала во Флориде с коммуникационным спутником Inmarsat-5 F4 для обеспечения самолетов сигналом Wi–Fi, трансляцию старта ведет компания-владелец РН SpaceX.
Старт ракеты-носителя был дан в 02.21 мск с космодрома на мысе Канаверал (Флорида). Ракета выводит на орбиту спутник Inmarsat-5 F4. Через полчаса после старта компания подтвердила успешный вывод аппарата на промежуточную орбиту.
"Подтверждено успешное отделение Inmarsat-5 Flight 4 и вывод на промежуточную геостационарную орбиту", — сообщила SpaceX в своем Twitter (https://twitter.com/spacex).
Аппарат весом 6,7 тонны станет четвертым в системе Global Xpress, развертывание которой началось в 2013 году. Спутник будет обеспечивать передачу сигнала, в том числе беспроводную интернет-связь для пассажиров авиалайнеров и морских судов.
Отделение первой ступени ракеты-носителя произошло через три минуты после старта. Все летные параметры в норме, запуск аппарата идет по плану.
После отделения от ракеты-носителя спутник займет свое место на геостационарной орбите на высоте 35,7 тысячи километров над Землей.

Цитировать16 May 2017: Inmarsat (LON: ISAT), the world's leading provider of global mobile satellite communications, has confirmed the successful launch of the fourth, high-speed broadband communications satellite in its transformational Global Xpress (GX) constellation.

Inmarsat GX is the world's first globally available, broadband connectivity service and was created to enable communities across the world to benefit from the emerging digital society.

Inmarsat-5 F4 (I-5 F4) was launched by SpaceX on a Falcon 9 rocket at 00:21 (BST) / 19:21 (ET) from the historic launch pad 39A at NASA's Kennedy Space Center in Florida. Following satellite separation at 00:53 (BST) / 19:53 ET, we acquired telemetry from our Perth ground station at 01:04 BST / 20:04 ET.

Спойлер

The launch team from Inmarsat and Boeing Network & Space Systems, the manufacturer of I-5 F4, are now raising the spacecraft to a geostationary orbit, at which point the satellite will deploy its solar arrays and reflectors, and undergo payload testing.

I-5 F4 joins the three GX satellites already in orbit, which have, since December 2015, been delivering unprecedented service speeds, global coverage, reliability and security to users on land, at sea and in the air.   The fourth satellite adds further capacity to the GX network, as well as in-orbit redundancy that further upgrades the reliability and resilience of Inmarsat's service offerings.

"For Inmarsat, reliability and resilience are paramount," said Rupert Pearce, CEO, Inmarsat. "Delivering global commercial services over the GX network, which we achieved at the end of 2015, was only the start of our Global Xpress project.  I-5 F4 augments the capabilities of GX and, alongside our existing L-band constellations, enables Inmarsat to provide guaranteed global connectivity to industries and governments worldwide.

"I would like to thank all my colleagues at Inmarsat, whose hard work and dedication is seeing Global Xpress setting a new standard of excellence for broadband communications in established VSAT markets, such the maritime and government sectors, while also rapidly gaining strong traction in new market areas, such as the rapidly expanding aviation passenger connectivity sector.

"I also wish to extend my sincere thanks to our satellite manufacturing partner Boeing and our launch partner SpaceX for delivering a successful launch outcome."

EL SEGUNDO, Calif., May 16, 2017 – The fourth Boeing [NYSE: BA] Inmarsat-5 satellite, which was launched yesterday, will noticeably expand the high-speed broadband service available through Inmarsat's Global Xpress network after the satellite becomes fully operational later this year.

The Inmarsat-5 satellites are uniquely able to provide seamless communications coverage through fixed and steerable beams that can be adjusted in real time to accommodate demand surges.

Спойлер

"Inmarsat-5 F4 joins our existing Global Xpress constellation, which is already being adopted as the new standard in global mobile broadband connectivity by companies, governments and communities around the world," said Michele Franci, CTO, Inmarsat. "Boeing has been an outstanding partner in our journey to make Global Xpress a reality."

This is the fourth Inmarsat-5 satellite Boeing has built for Inmarsat's Global Xpress network. After reaching its final orbit, the satellite will undergo testing and checkout before being declared operational.

"Our partnership with Inmarsat has enabled the creation of the world's only commercial global, mobile Ka-band network," said Mark Spiwak, president, Boeing Satellite Systems International. "This unique achievement is an example of Boeing's continuing commitment to deliver reliable, affordable and innovative solutions for our customers."

Boeing has a strategic marketing partnership with Inmarsat and currently provides both military Ka-band and commercial Global Xpress services to U.S. government customers.

Генеральным подрядчиком по созданию космических аппаратов Inmarsat-5F является компания Boeing Satellite Systems, которая создает спутники на базе своей проверенной платформы 702HP. Каждый аппарат рассчитан на 15 лет активного существования на орбите. В октябре 2013 года Inmarsat заказал компании Boeing четвертый спутник, который будет резервным на этапе развертывания орбитального сегмента, а в дальнейшем послужит для расширения возможностей системы GX.
....
Каждый спутник сети GX формирует 89 фиксированных точечных лучей в Ка-диапазоне, что позволяет пользователям с компактными терминалами (60-80 см) высокоскоростную (до 50 Мбит/с - downlink и 5 Мбит/с - uplink) передачу данных, телефонию, доступ в Интернет на суше, море и в воздухе.

Основными потребителями сети GX станут правительственные организации разных стран для передачи данных в чрезвычайных ситуациях (когда наземные сети повреждены или отсутствуют), корпоративные и частные заказчики. Применение системы разнообразно: для телемедицины и дистанционного образования, для контроля инфраструктуры (нефте- и газопроводов, энергосетей, транспорта) и в других отраслях.

Абонентское оборудование для сети Inmarsat GX производит компания Cobham. Разработкой системной платформы сети Inmarsat GX занимается iDirect и Cisco.

Терминалы GX разделяются на три типа – фиксированные на подвижных платформах, переносимые и фиксированные, поэтому они в равной степени подходят для пользователей на земле, на море и в воздухе.

ФГУП «Морсвязьспутник» ведет переговоры с компанией Инмарсат о предоставлении на территории Российской Федерации услуг Инмарсат 5-го поколения GX.

На территории Российской Федерации услуги Инмарсат 5-го поколения GX в настоящий момент не предоставляются.

ЦитироватьIf this does end up going to a super-synchronous transfer orbit, then it will provide an interesting comparison with the Echostar 23 launch.  Echostar 23 was ~5500kg and was sent to 179km x 35903km x 22.43o (http://forum.nasaspaceflight.com/index.php?topic=41932.msg1655058#msg1655058), which works out to about GTO-1711.  Inmarsat is currently listed as 6100kg.  If they have enough performance in the F9 to get it to super-synch, this may be the first definite upgraded performance launch (there seems to be a bit of debate whether NROL-76 used upgraded thrust or not).

This might also depend on the desires of the customer.  If you have more performance than you need to reach a minimal GTO (GTO - 1800 for the cape, 179 x 36000 x 28o) , you can use it in two different ways.
(a) Keep the apogee at GTO, but reduce the inclination.  Here they reduced it from 28o to 22.43, saving the customer about 100 m/s to get to GEO.
(b) Increase the apogee, but keep the inclination.  With the same delta-V, they could have generated an orbit that was about 179 x 48000 x 28o (super-sync).  In the case of Echostar this would have been a very similar reduction in delta-V.

Option (b) involves more navigation (at least two burns and longer intermediate orbits) by the customer, and the satellite has to be capable of working when above GEO.  But in some cases it can be significantly less delta-V required by the launcher.   In general, (a) is better if you have only a little extra performance to use.  As performance increases, the two techniques become roughly tied at about GEO-1700 from the cape.  But for better orbits than that, the super-sync method (b)  pulls ahead.   For example, the same delta-V can give you 179 x 119,000 x 28 (for GTO-1500) or 179 x 36000 x 17.7 (for GTO-1625).

From the point of view of SpaceX, the only difference is the pointing of the second stage at the GTO injection burn.  It's at the same place and lasts the same time in either case.  So I suspect they offer the option to the customer, and the customer chooses based on the navigation required, the delta-V saved, and the capabilities of the satellite.

Here is a plot of the effectiveness of both approaches, starting from a 180x180x28o parking orbit.

Сорри за ламерский вопрос. Каким образом спутник в дальнейшем может снизить апогей с получением на этом энергии?

ЦитироватьВиктор Воропаев пишет:
Точнее, с экономией энергии. В простейшем виде: полная энергия есть сумма потенциальной и кинетической. Забросили повыше (затратив энергию химических связей ракетного топлива) - получили избыток потенциальной энергии. Теперь распоряжаемся им против сил тяготения и по своему усмотрению, хошь на подъём перигея, хошь на снижение апогея, хошь на изменение наклонения...

В моем ламерском понимании, чем выше апогей, тем дешевле менять наклонение. То есть теряется ХС, которую потом нужно затратить на снижение апогея, но уменьшение наклонения обходится дешевле и в сумме получается выигрыш.

ЦитироватьВ общем случае выгодным такой переход становится при необходимости разворота плоскости переходной орбиты на угол более 38,6 градуса, но, как известно, широта всех иностранных космодромов, используемых для запусков на ГСО, меньше этой величины. Поэтому за рубежом данная схема применяется, когда РН недогружена и нужно как-то использовать избыток ХС, не увеличивая число включений и САС РБ. Т.е. в случае отказа от апогейного импульса РБ запуск через суперсинхронную орбиту становится выгоднее, чем простой разворот плоскости орбиты во время перигейного импульса РБ, даже при старте с низких широт.

Это что-то вроде того, как волчок сопротивляется наклону? Выше орбитальная скорость - сложнее "наклонить"?

В высоком апогее тело, грубо говоря, почти неподвижно висит, и его надо только чуть толкнуть в сторону, чтобы изменить наклонение. А в перигее - наоборот.
