While the astronauts were resting, Dragon completed another major maneuver: a 531-second long Boost burn at 21:25 EDT (01:25 UTC), as well as a handful of short burns calculated by Dragon’s onboard computers. No collision avoidance maneuver was performed, and the object passed without incident. Later, it was realized that the object was much further away than first thought, and the risk of possible conjunction was much lower. The astronauts donned their suits to protect against the risk of Endeavour depressurizing if a collision occurred. This was the final burn before which the crew went to sleep.Ĭrew Dragon Endeavour lifts off from the Kennedy Space Center aboard Falcon 9 – via Stephen Marr for NSFĪbout 30 minutes prior to their scheduled sleep period, SpaceX’s Core Operations and Resources Engineer (CORE) alerted the crew about a possible conjunction with an object in orbit, within just 20 minutes. These thrusters - powered by Monomethylhydrazine and Dinitrogen tetroxide -conduct a series of five major burns and maneuvers to rendezvous with the ISS.Įndeavour‘s first post-launch maneuver, named the Phase Burn, was conducted at 06:38 EDT (10:38 UTC) for 123 seconds. The same Crew Dragon spacecraft was used during the historic Demo-2 mission, when NASA Astronauts Bob Behnken and Doug Hurley tested the spacecraft in orbit and later docked it to the ISS.Īfter a perfect liftoff from historic Launch Complex 39A at the Kennedy Space Center, Crew Dragon Endeavour separated from the second stage of Falcon 9 and started the deployment of the nose cone which protects the docking mechanism and primary Draco thrusters during launch. It is also the first mission to utilize a flight-proven Crew Dragon spacecraft and Falcon 9 first stage. ![]() ![]() NASA astronauts Shane Kimbrough and Meghan McArthur, European Space Agency astronaut Thomas Pesquet, and Japanese Space Exploration Agency astronaut Akihiko Hoshide have joined the Expedition 64 crew as SpaceX’s Crew Dragon Endeavour docked successfully to the International Space Station (ISS) at 5:08 AM EDT (09:08 UTC) on Saturday 24 April.Ĭrew-2 is the first crewed mission for NASA and SpaceX in 2021 and their third crewed launch in 12 months after a 10-year absence of human spaceflight from the United States.
