SpaceX Crew-4 was 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[6] before docking with the International Space Station (ISS) at 23:37UTC. It followed 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 were on board the mission.

Crew-4 was 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".[7] 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).[8]

Crew

NASA astronauts Kjell Lindgren and Robert Hines were announced on 12 February 2021 to the crew. Samantha Cristoforetti was named the commander of Expedition 68 on 28 May 2021.[9] Jessica Watkins was named mission specialist on 16 November 2021.[10] Cristoforetti was later removed as commander of Expedition 68 due to the shortening of the Crew-4 mission.[11]

Mission

The mission duration was 170 days.[4] The European part of the mission was called Minerva, named after the Roman goddess of wisdom,[12] and it was European astronaut Cristoforetti's second mission to the ISS.
