SpaceX Crew-4 mission patch Hines, Cristoforetti, Watkins, and Lindgren (L-R) |
SpaceX Crew-4 is the Crew Dragon's fourth NASA Commercial Crew operational flight, and its seventh overall crewed orbital flight. The mission launched on 27 April 2022 at 07:52 UTC[4] before docking with the International Space Station (ISS) at 23:37 UTC. It follows shortly after the private Axiom 1 mission to the ISS earlier in the month utilizing SpaceX hardware. Three American (NASA) astronauts and one European (ESA) astronaut are onboard the mission.[5][6] [7]
Crew-4 is the maiden flight of the Crew Dragon spacecraft named Freedom, named such by the crew because it "celebrates a fundamental human right, and the industry and innovation that emanate from the unencumbered human spirit".[8] The booster used on this mission was the B1067, which makes it the first Commercial Crew mission to use a booster on its fourth flight (it previously was used to launch SpaceX Crew-3 in 2021).[9]
NASA astronauts Kjell Lindgren and Robert Hines were announced on 12 February 2021 to the crew.[5][6] Samantha Cristoforetti was named the commander of Expedition 68 on 28 May 2021.[10] Jessica Watkins was named Mission specialist on 16 November 2021.[11] Cristoforetti was later removed as commander of Expedition 68 due to the shortening of the Crew-4 mission.[12]
