Метеоспутник GOES-T прошел этап критического тестирования
Метеорологический спутник GOES-T прошел этап термовакуумных испытаний. В ходе них инженеры проверяли способность космического аппарата работать на геостационарной орбите. При этом в ходе тестирования была подтверждена способность спутника работать в диапазоне температур от минус 55 градусов по Цельсию до плюс 87 градусов по Цельсию. В качестве стенда использовалась большая камера с габаритами 29 х 65 футов, сообщает Ecoruspace.
В феврале спутник успешно прошел вибрационные и акустические испытания.

...
GOES-T is the third of the next generation of weather satellites operated by NOAA, giving sequence to the GOES system. The GOES-R Series (including GOES-R, -S, -T and -U) provides advanced imagery and atmospheric measurements of Earth's weather, oceans and environment, real-time mapping of total lightning activity, and improved monitoring of solar activity and space weather.

Welcome to Cape Canaveral and the start of another #AtlasV launch campaign! Follow along today as we begin stacking the rocket to launch the @NOAASatellites #GOEST weather observatory for @NASA_LSP on March 1 at 4:38pmEST (2138 UTC).

  ULA  @ulalaunch
The #AtlasV 541 with four SRBs will be used to launch  @NOAASatellites' #GOEST into an optimized geosynchronous transfer orbit. This orbit will require less fuel for the spacecraft to reach its operational station in space and enable a longer mission life.

#GOEST is @NOAA's advanced weather satellite to improve the accuracy of life-saving forecasts. It will operate 22,300 miles (36,000 km) above Earth to cover the western U.S., Alaska, Hawaii, Mexico, Central America and surrounding Pacific Ocean.

NOAA's GOES-T Satellite Gets Payload Protection

Now safely encapsulated, the National Oceanic and Atmospheric Administration's (NOAA) Geostationary Operational Environmental Satellite-T (GOES-T) satellite has completed another key milestone in preparation for its March 1, 2022, launch from Cape Canaveral Space Force Station in Florida.

Inside the Astrotech Space Operations facility in nearby Titusville, the two halves of the United Launch Alliance Atlas V payload fairings were brought together and installed around GOES-T. The payload fairings will secure and protect the satellite during launch.
"Things are getting real now; GOES-T is fully assembled and ready for launch," said GOES-T Mission Manager Rex Engelhardt. "Next week, we will be holding the final launch reviews and exercising the teams on their launch consoles in preparation for launch day."
Last month, technicians began integrated operations, which included lifting and mating the spacecraft to the payload adapter – a piece of hardware that interfaces mechanically between the rocket and the spacecraft. On Feb. 17, GOES-T will be transported and mated to the launch vehicle. The fully assembled launch vehicle is targeted to roll to the launch pad on Feb. 28.
The third satellite in NOAA's GOES-R series, GOES-T will lift off atop the Atlas V 541 rocket from Space Launch Complex 41. The launch is managed by NASA's Launch Services Program based at the agency's Kennedy Space Center, America's multi-user spaceport.
The GOES satellite network helps meteorologists observe and predict local weather events that affect public safety, including thunderstorms, tornadoes, fog, hurricanes, flash floods, and other severe weather. GOES-T will provide critical data for the U.S. West Coast, Alaska, Hawaii, Mexico, Central America, and the Pacific Ocean.

Не понятен порядок сборки РКН.

Как КА стыкуется с Центавром, а потом происходит сборка ГО?

[АСПОС ОКП]

Белая пимпочка внизу головной части - это переходник к "Центавру", который вертикально монтируется на CBC.

Сначала Центавр, потом на него КА с ГО.

Белая пимпочка внизу головной части - это переходник к "Центавру", который вертикально монтируется на CBC.

Вы не можете просматривать это вложение.

Я так понимаю, что под пимпочкой переходник с  кольцевым узлом разделения.
За который удерживается КА тремя или четырьмя тягами (желтым).
Таким образом процесс интергации представляется мне следующим:
1. Все поднимается над РН, пимпочка снимается.
2. Конструкция ставится на Центавр, переходник монтируется (вот тут уже большой вопрос по доступу к переходнику)
3. Желтые тяги снимаются (как их снять без воздействий на Центавр?)
4. Убирается черная пленка (КА начинает быть подвержен атмосферным воздействиям)
5. Верх ГО опускается на низ ГО  (КА прекращает быть подвержен атмосферным воздействиям)
6. ГО собирается и корсет снимается.

Это так происходит?

ATLAS V TO LAUNCH GOES-T
A United Launch Alliance (ULA) Atlas V 541 rocket will launch Geostationary Operational Environmental Satellites (GOES) –T mission for NOAA, NASA and NASA's Launch Services Program (LSP). The launch is planned for March 1 from Space Launch Complex-41 at Cape Canaveral Space Force Station, Fla.

Launch date: March 1, 2022
Launch time: The two-hour launch window opens at 4:38 p.m. EST (2138 UTC)
...
GOES-T will provide NASA and NOAA with continuous imagery and atmospheric measurements of Earth's Western Hemisphere, lightning detection and mapping, solar imaging and space weather monitoring. This is the third satellite in NOAA's GOES-R Series, and will continue the revolutionary improvements brought by GOES-R and GOES-S, also launched on ULA's Atlas V rocket.

Atlas V makes its way out to SLC-41 ahead of tomorrow's #GOEST launch.
At a blistering 3 mph, and a few stops along the way, it takes about 45 minutes to cover the 1/3 mile between the Vertical Integration Facility and SLC-41.
