SpaceX Crew-2 will be the second crewed operational flight of a Crew Dragon spacecraft, and the third overall crewed orbital flight. The mission is planned to launch on 23 April 2021 at 09:49:00 UTC (5:49:00 AM EDT).[1][2] The Crew-2 mission will transport four members of the crew to the International Space Station (ISS).[3] Crew-2 is also planned to use the same capsule as Demo-2 and same booster as Crew-1.

Crew

On 28 July 2020, JAXA, ESA and NASA confirmed their astronaut assignments aboard this mission.[4][5] Alongside the 3 other crew members, Megan McArthur will use the same seat of the SpaceX Crew Dragon Endeavor in this mission which her husband, Bob Behnken, used in SpaceX Demo-2 mission, the first mission of the Endeavor capsule.[6]

Mission

The second SpaceX operational mission in the Commercial Crew Program is currently scheduled to launch on 23 April 2021.[1][2] The Crew Dragon Endeavour (C206), will dock to the International Docking Adapter (IDA) on the Harmony module. All crew are veteran astronauts, though this will be Megan McArthur's first visit to the ISS (as her first spaceflight was a shuttle mission to the Hubble Space Telescope). Akihiko Hoshide will serve as the second Japanese ISS commander during his stay.[4]

This is the second mission by Thomas Pesquet to the International Space Station and will be called Alpha, after Alpha Centauri, the closest star system to Earth, following the French tradition to name space missions after stars or constellations.[5] This mission will be the first one with a used booster and astronauts onboard.

Addition of European Robotic Arm to ISS

The European Robotic arm is shown on the left attached to the Nauka module, the spare elbow joint with two limbs is shown on the right, attached to the Rassvet module

The SpaceX Crew-2 is scheduled to arrive at the ISS on 24 April 2021, well ahead of the launch and docking to the Nauka module of a Proton-M rocket on 15 July 2021 that will carry a portion of the European Robotic Arm (the other portion arrived aboard the STS-132 Space Shuttle mission on 16 May, 2010, and is attached to the Rassvet module).[9]
