SpaceX Crew-2 is the second crewed operational flight of a Crew Dragon spacecraft, and its third overall crewed orbital flight. The mission was launched on 23 April 2021 at 09:49:02 UTC (5:49:02 AM EDT). [1] The Crew-2 mission transported four members of the crew to the International Space Station (ISS). [2] Crew-2 also used the same capsule as Demo-2 ( Endeavour) and used the same booster as Crew-1 (B1061.1). Endeavour docked with the International Space Station on 24 April 2021 at 09:08 UTC. [3]


On 28 July 2020, JAXA, ESA and NASA confirmed their astronaut assignments aboard this mission. [4] [5]

Addition of European Robotic Arm to ISS

SpaceX Crew-2 arrived at the ISS on 24 April 2021, well ahead of the launch and docking of the Nauka module launching on a Proton-M launch vehicle on 15 July 2021 that will carry a portion of the European Robotic Arm (ERA). Expedition 65 crew members will oversee the installation of Nauka and the ERA on the ISS. [7]

The second SpaceX operational mission in the Commercial Crew Program launched on 23 April 2021. [8] [9] The Crew Dragon Endeavour (C206), will dock to the International Docking Adapter (IDA) on the Harmony module. This mission is the first with astronauts onboard with a previously used booster rocket. [10] [11]

All crew are veteran astronauts, though this is Megan McArthur's first visit to the ISS (as her first spaceflight was a shuttle mission to the Hubble Space Telescope). Alongside the three other crew members, Megan McArthur is using the same seat of the SpaceX Crew Dragon Endeavour in this mission which her husband, Bob Behnken, used in SpaceX Demo-2 mission, the first mission of the Endeavour capsule. [12] Akihiko Hoshide will serve as the second Japanese ISS commander during his stay. [4] It 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.

  1. ^ This relocation will happen only if Boeing Starliner comes for its 5 day OFT 2 mission within this time period otherwise this will happen a month or 30 days before arrival of SpaceX Crew-3 since this is now a Commercial Crew Program routine that for safety and efficiency that the U.S. crewed spacecrafts are docked to Harmony forward port that is the harmony port that is at the front of the ISS, according to its normal direction of travel and orientation which is easier to dock, so the crewed spacecraft docked to forward port at the start of the mission is relocated to Harmony zenith port, a space facing port at the top of the ISS approximately a month before the next spacecraft arrives due to the reason that only these two ports on the US Orbital Segment are ports with International Docking Adapter (IDA) and free Pressurized Mating Adapter (PMA), where crewed spacecraft like SpaceX Crew Dragon and Boeing Starliner can dock to ISS, while almost each of these spacecrafts need to be docked to ISS and are replaced with another spacecraft of the same type every six months[ citation needed]
