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".[10] 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).[11]

CrewEdit

NASA astronauts Kjell Lindgren and Robert Hines were announced on 12 February 2021 to the crew.[7][8] Samantha Cristoforetti was named the commander of Expedition 68 on 28 May 2021.[12] Jessica Watkins was named mission specialist on 16 November 2021.[13] Cristoforetti was later removed as commander of Expedition 68 due to the shortening of the Crew-4 mission.[14]
