SpaceX Crew-4 will be the fourth crewed operational flight of a Crew Dragon spacecraft, and the fifth overall crewed orbital flight. The mission is currently planned for launch in April 2022. Either this flight or Boeing Starliner-1 will launch in April 2022; the other will launch at a later date.[2] The Crew-4 mission will transport four members of the crew to the International Space Station (ISS). As of May 2021, two NASA astronauts and one ESA astronaut have been assigned to the mission, with one more international astronaut to be named later.[3][4]


NASA astronauts Kjell Lindgren and Robert Hines were announced on 12 February 2021 to the crew.[3][4] Samantha Cristoforetti was named the commander of Expedition 68 on 28 May 2021.[5]
