SpaceX just test-fired a Falcon 9 rocket on pad 39A at the Kennedy Space Center.

The rocket's Merlin engines appeared to fire for several seconds.

We'll await confirmation from SpaceX of a successful test ahead of a planned launch Saturday.

NASA and SpaceX are targeting Saturday, Dec. 5, for SpaceX's 21st Commercial Resupply Services (CRS-21) mission to the International Space Station. Weather officials with the U.S. Air Force 45th Space Wing are predicting a 40% chance of favorable weather conditions for liftoff of the SpaceX Falcon 9 rocket and Cargo Dragon spacecraft from Kennedy Space Center's Launch Complex 39A in Florida.

Primary weather concerns are the cumulus cloud rule, thick cloud layer rule, and flight through precipitation.

CRS-21 is the first mission under the company's second Commercial Resupply Services contract with NASA and the first flight of the upgraded cargo version of Dragon 2. The mission will deliver supplies, equipment, and critical materials to support dozens of the more than 250 science and research investigationsthat will occur aboard the orbiting laboratory during Expeditions 64 and 65.

Liftoff of the Falcon 9 is scheduled for 11:39 a.m. EST, and Dragon is slated to autonomously dock at the space station at approximately 11:30 a.m. EST on Sunday, Dec. 6. NASA astronauts and Expedition 64 Flight Engineers Kate Rubins and Victor Glover will monitor docking operations.

Follow live coverage of the CRS-21 mission and prelaunch events here on the blog, NASA TV, and the agency's website:

  • 1 p.m. EST Friday, Dec. 4 - Virtual #NASASocial Science and Station Q&A
  • TBD Friday, Dec. 4 - Prelaunch news conference from Kennedy with representatives from the International Space Station Program Office, SpaceX, and the U.S. Air Force 45th Space Wing
  • 11:15 a.m. EST Saturday, Dec. 5 - Live launch countdown coverage begins

The SpaceX recovery fleet is converging on the landing zone, 623 km downrange, for the CRS-21 mission.

As it's a Dragon launch, there is no fairing so no fairing recovery.

Любопытно: предыдущие два полета Crew Dragon (Demo-1 и Demo-2) продемонстрировали, что корабль не умеет выдавать тормозной импульс для схода с орбиты без предварительного отделения негерметичного грузового отсека. В первом случае транк остался на орбите высотой 390 км, во втором на  орбите высотой 240 км. В случае НШС - нестыковка с МКС - придется решать проблему с отделением транка с шлюзом весом 1090 кг, что в сумме даёт около 2790 кг суммарно. Экипажа внутри корабля нет.

ЦитатаЗапуск миссии CRS-21 - 5 декабря в 19:39 МСК (16:39 UTC)
Миссия по снабжению МКС доставит на космическую станцию научный материал для десятков исследований и экспериментов, необходимое станции оборудование, запасы для экипажа и первый частный шлюзовой модуль Bishop Airlock от компании Nanoracks.
Погода: 40% за GO. Команда мониторит условия в океане, где погода также плохая. Резервная дата запуска: 6 декабря (80% за GO)
Место старта: площадка LC-39A, Космический центр им. Кеннеди
Корабль: Cargo Dragon (Dragon 2) С208 (новый)
РН: Falcon 9 FT, 1-я ступень B1058.4 (4-й полёт)
Ранее ступень использовалась в миссиях: Demo-2 (май 2020), ANASIS-II (июль 2020) и Starlink-12 (октябрь 2020).
Спасение 1-й ступени: платформа OCISLY, 623 км от места старта, Атлантический океан

Стыковка с МКС: через сутки, 6 декабря. IDA-3, модуль Гармония.

На МКС корабль доставит 2 972 кг различных грузов:
-- 1 882 кг в герметичном отсеке корабля (953 кг научных исследований, 364 кг запасов для экипажа, 317 кг оборудования для станции, 120 кг оборудования для выхода в открытый космос, 46 кг компьютерного оборудования и 24 кг оборудование для российского сегмента станции.
-- 1 090 кг в негерметичном отсеке (частный шлюзовой модуль Nanoracks Bishop Airlock).

Обратно корабль вернёт 2358 кг грузов.
Возвращение на Землю: январь 2021, приводнение у восточного побережья Флориды, Атлантический океан.

Особенности миссии:
-- 1-я миссия грузового корабля SpaceX Cargo Dragon 2-го поколения (Dragon 2)
-- 1-я миссия второй фазы контракта на доставку грузов на МКС в рамках программы NASA Commercial Resupply Services (CRS)
-- 1-й раз, когда новый космический корабль будут запускать на уже использованной в полёте ракете
-- 1-й полёт миссии NASA на ускорителе, который будет использован в 4-й раз
-- 1-й раз, когда ракета-носитель с коммерческой историей запусков была вновь использована для запуска миссии NASA
-- Планируется 1-я автоматическая стыковка грузового корабля SpaceX с МКС непосредственно к стыковочному адаптеру
-- 1-й раз к МКС буду одновременно пристыкованы сразу 2 корабля SpaceX (миссий Crew-1 и CRS-21)
-- Попытка нового рекорда по кратчайшему времени от запуска до стыковки для беспилотного космического корабля, который пристыкуется к американскому сегменту МКС
-- Попытка рекорда на кратчайшее время, в течение которого ракета-носитель совершила четыре полёта - 189 дней (Demo-2 - CRS-21). Предыдущий рекорд 291 день

Это будет 24-й запуск компании в этом году, 101-й пуск Falcon 9 и 109-й запуск в истории SpaceX.
SpaceX проведут трансляцию этого запуска.

Photo credit: NASA/Tony Gray and Tim Terry

Beginning at 1 p.m. EST today, Dec. 4, tune in for the CRS-21 Virtual #NASASocial Science and Station Q&A, airing live on NASA TV and the agency's website. Following this, later in the afternoon, there will be a prelaunch news conference (this will occur approximately one hour after the conclusion of the launch readiness review.) Participants include:

  • Kenny Todd, deputy program manager, International Space Station Program Office
  • Kirt Costello, chief scientist, International Space Station Program Office
  • Sarah Walker, director, Dragon Mission Management, SpaceX
  • Melody Lovin, launch weather officer, U.S. Air Force 45th Space Wing



SpaceX's 21st Commercial Resupply Services mission to the International Space Station is scheduled for tomorrow, Dec. 5. Liftoff of the SpaceX Falcon 9 rocket and cargo Dragon spacecraft is targeted for 11:39 a.m. EST from Launch Complex 39A at NASA's Kennedy Space Center in Florida. Live launch coverage begins at 11:15 a.m. EST here on the blog, NASA TV, and the agency's website.

Weather officials with the U.S. Air Force 45th Space Wing are now predicting a 50% chance of favorable weather conditions for liftoff. Primary weather concerns continue to revolve around the cumulus cloud rule and thick cloud layer rule.

Packed inside Dragon are critical science investigations, supplies, and equipment bound for the orbiting laboratory. One item for delivery is the Nanoracks Bishop Airlock - the first commercially owned and operated airlock that, once installed, will provide a variety of capabilities to the space station, such as payload hosting, robotics testing, and satellite deployment.

ЦитатаCRS-21 MISSION

SpaceX is targeting Saturday, December 5 for launch of its twenty-first Commercial Resupply Services mission (CRS-21), which will launch from Launch Complex 39A (LC-39A) at Kennedy Space Center, Florida. Launch is targeted for 11:39 a.m. EST, or 16:39 UTC. Dragon will separate from Falcon 9's second stage about eleven minutes after liftoff and autonomously dock to the space station on Sunday, December 6. A backup launch opportunity is available on Sunday, December 6 at 11:17 a.m. EST, or 16:17 UTC.

This is the first flight of the updated cargo version of Dragon, which is capable of carrying about 20 percent more volume than the previous version of Dragon and has double the amount of powered locker cargo capability. Dragon is now designed for up to five flights to and from the space station, and this cargo version of the spacecraft can stay on station more than twice as long as the previous version of Dragon.

The Falcon 9 first stage rocket booster supporting this launch previously supported launch of Dragon's first flight with NASA astronauts to the International Space Station (Demo-2), the ANASIS-II mission, and a Starlink mission. Following stage separation, SpaceX will land Falcon 9's first stage on the "Of Course I Still Love You" droneship, which will be located in the Atlantic Ocean.
