ЦитироватьTDRS L readied for mid-January launch
By Justin Ray
Spaceflight Now

 The next-generation NASA science-relay satellite is being prepped for shrouding in the bullet-shaped nose cone that will shield it during launch Jan. 23.

At the commercial Astrotech processing campus in Titusville, the Tracking and Data Relay Satellite L, or TDRS L, is being readied to join NASA's constellation of communications satellites 22,300 miles above Earth.

The craft will be encapsulated next Wednesday, Jan. 8 and then moved across the river to Cape Canaveral on Monday, Jan. 13 for mating to its Atlas-Centaur rocket.

The United Launch Alliance Atlas 5 will carry the spacecraft on a two-hour flight to geosynchronous transfer orbit, the normal dropoff point for communications satellites. From there, TDRS L will maneuver itself into a circular orbit and undergo months of testing before being declared operational.

TDRS satellites date back to 1983 to establish communications with the space shuttle. The system has grown over the years to provide coverage to the Hubble Space Telescope, NASA's low-Earth orbiting satellite fleet and International Space Station.

Liftoff is planned for Jan. 23 at 9:05 p.m. EST.

The Tracking and Data Relay Satellite L, or TDRS L, is scheduled for liftoff fr om Cape Canaveral's Complex 41 next Thursday, Jan. 23, at 9:05 p.m. EST. The evening's available window extends 40 minutes.
It continues the third era of spacecraft for NASA's space network for routing communications fr om the International Space Station, transmitting science data from orbiting satellites and tracking booster rockets.
The system began taking shape in 1983, replacing the smattering of ground stations around the world that provided periodic contact with orbiting spacecraft. Over the past three decades, however, TDRS created a constellation of geosynchronous satellites 22,300 miles above Earth for constant communications.
From such a high vantage point, TDRS satellites look down on the entire globe, receiving transmissions from fast-moving craft flying only a few hundred miles in altitude and channeling those signals to dedicated terminals for dissemination to mission controllers.
To keep the infrastructure maintained, NASA is preparing to launch TDRS L, plus sister-satellites TDRS K a year ago and TDRS M in 2015. Together, they will ensure the constellation's viability well into the next decade.
After deploying the first generation of craft aboard space shuttle missions through 1995, a second batch flew on Atlas 2A rockets between 2000 and 2002. Now, NASA has bought this latest trio using mostly the same specs as the last birds, albeit with updated components.
TDRS L was shipped to the Cape from Boeing's manufacturing factory on Dec. 6. It underwent final electrical checkouts, the loading of its maneuvering propellant and encapsulation in the rocket's 14-foot-diameter aluminum nose cone.
In the wee hours Monday morning, the spacecraft departed nearby Titusville wh ere it had undergone pre-flight processing at the commercial Astrotech facilities and headed for the spaceport.
Traveling across 405 in a slow-moving convoy, the payload turned northward to pass through Kennedy Space Center, going by the Vehicle Assembly Building and the old space shuttle launch pad before cruising down along the beach to the Atlas rocket's Vertical Integration Facility, arriving at 5:19 a.m. EST.
After pulling up to the doorway of the 30-story-tall VIF wh ere the Atlas rocket was assembled and tested, technicians went to work attaching the heavy-duty lifting sling to hoist the spacecraft in the bullet-shaped fairing off the ground and atop the Centaur upper stage. The initial phase of attachment was completed at 9:55 a.m. EST.
The move came 20 years to the day after the TDRS F satellite was launched aboard shuttle Endeavour.
A combined systems test between TDRS L and the Atlas vehicle will occur in the coming days to verify the payload and rocket are talking to each other properly, followed by final closeouts of the vehicle for flight.
Mission managers will gather for the Launch Readiness Review next Tuesday to assess the progress of work and any issues before giving concurrence for rollout to the pad on Wednesday.
The United Launch Alliance-made, two-stage rocket was stacked aboard a mobile launching platform that will wheel the fully-assembled vehicle out to the launch pad one-third-of-a-mile away.
The Atlas 5 system at the Cape is meant to spend minimal time on the "clean pad" at Complex 41, which has no gantry.
The launch countdown picks up around 2 p.m. on Thursday afternoon, leading to fueling operations starting at 7 p.m.

Спутник слежения и ретрансляции данных TDRS-L готовится к запуску


В пункте подготовки полезной нагрузки в Титусвилле, TDRS-L (Tracking and Data Relay Satellite / Спутник слежения и ретрансляции данных), в настоящее время заключается в капсулу головного отсека. На этом снимке можно увидеть, как его поднимают краном для того, чтобы установить на транспортер для переправки на пусковой комплекс 41 (Launch Complex 41) Станции Воздушных Сил в Кейп Канаверал.

Спутник TDRS-L станет частью второго из трех космических аппаратов нового поколения, которые были сконструированы для того, чтобы обеспечить непрерывную работу Космической Сети (Space Network) агентства NASA. TDRS-L согласно плану должен быть запущен с пускового комплекса 41 космодрома Кейп Канаверал при помощи ракеты Atlas V (Атлас V), построенной предприятием United Launch Alliance. 30-минутное стартовое окно для запуска открывается 23 января в 21:05 по местному времени (06:05 24 января по московскому времени ).

В настоящее время спутниковая система Tracking and Data Relay Satellite состоит из восьми спутников, которые находятся на орбите, распределенных таким образом, чтобы обеспечивать почти непрерывный контакт с находящимися на орбите космическими аппаратами, начиная с Международной Космической Станции и заканчивая Космическим Телескопом Hubble (Хаббл), с решетками антенн научных обсерваторий.

NASA запустило с мыса Канаверал спутник связи нового поколения
http://itar-tass.com/nauka/910172

ЦитироватьНЬЮ-ЙОРК, 24 января. /Корр.ИТАР-ТАСС Даниил Студнев/. С мыса Канаверал в штате Флорида запущена ракета-носитель Atlas 5 с коммуникационным спутником нового поколения TDRS-L. Ракета стартовала в четверг в 21:33 по времени Восточного побережья США (06:33 мск пятницы).

"Полёт проходит в штатом режиме. Все системы исправно работают", – заявил после старта представитель NASA Марти Малиновски. Он также добавил, что примерно через полтора часа после запуска TDRS-L будет выведен на геостационарную переходную орбиту, откуда через 10-15 дней маневрирования он, как ожидается, переместится на круговую орбиту высотой около 36 тыс. км. Затем специалисты проведут тестирование аппарата и, если оно пройдёт успешно, он заступит на службу NASA.

Спутник будет использоваться в системе слежения и передачи данных NASA и для связи с Международной космической станцией (МКС). Кроме того, с помощью этого аппарата будут передаваться изображения, получаемые телескопом "Хаббл", а также данные с метеорологических спутников.

Запущенный в четверг спутник – уже второй из трёх коммуникационных спутников нового поколения, с помощью которых NASA планирует обновить постепенно устаревающую сеть связи. Первый был выведен на орбиту в конце января 2013 года. Стоимость двух аппаратов составила порядка 715 млн долларов.

Срок эксплуатации этих аппаратов рассчитан минимум на 15 лет. О дате запуска третьего спутника пока не сообщалось.

Разработка глобальной Спутниковой системы слежения и передачи данных (TDRSS) NASA была завершена в 1973 году, а первый спутник связи в рамках этой системы - TDRS-A - был выведен на орбиту спустя десять лет. В настоящее время флот связи NASA включает восемь действующих аппаратов.

NASA Launches Third Generation Communications Satellite
http://www.nasa.gov/press/2014/january/nasa-launches-third-generation-communications-satellite/

ЦитироватьNASA's Tracking and Data Relay Satellite L (TDRS-L), the 12th spacecraft in the agency's TDRS Project, is safely in orbit after launching at 9:33 p.m. EST Thursday aboard a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida.

Ground controllers report the satellite -- part of a network providing high-data-rate communications to the International Space Station, Hubble Space Telescope, launch vehicles and a host of other spacecraft -- is in good health at the start of a three-month checkout by its manufacturer, Boeing Space and Intelligence Systems of El Segundo, Calif. NASA will conduct additional tests before putting TDRS-L into service.

"TDRS-L and the entire TDRS fleet provide a vital service to America's space program by supporting missions that range from Earth-observation to deep space discoveries," said NASA Administrator Charles Bolden. "TDRS also will support the first test of NASA's new deep space spacecraft, the Orion crew module, in September. This test will see Orion travel farther into space than any human spacecraft has gone in more than 40 years."

The mission of the TDRS Project, established in 1973, is to provide follow-on and replacement spacecraft to support NASA's space communications network. This network provides high data-rate communications. The TDRS-L spacecraft is identical to the TDRS-K spacecraft launched in 2013.

"This launch ensures continuity of services for the many missions that rely on the system every day," said Jeffrey Gramling, TDRS project manager at NASA's Goddard Space Flight Center, Greenbelt, Md.
The TDRS fleet began operating during the space shuttle era with the launch of TDRS-1 in 1983. Of the 11 TDRS spacecraft placed in service to date, eight still are operational. Four of the eight have exceeded their design life.

Boeing Space and Intelligence Systems completed the TDRS-L integration and testing at its satellite factory in El Segundo in November and launch processing began after the spacecraft arrived in Florida Dec. 6.
TDRS-M, the next spacecraft in this series, is on track to be ready for launch in late 2015.

NASA's Space Communications and Navigation Program, part of the Human Exploration and Operations Mission Directorate (HEOMD) at the agency's Headquarters in Washington, is responsible for the space network. The TDRS Project Office at Goddard manages the TDRS development program. Launch management of the launch service for TDRS-L is the responsibility of HEOMD's Launch Services Program based at the agency's Kennedy Space Center in Florida.  United Launch Alliance provided the Atlas V rocket launch service.
