SpaceX Crew-8 is the eighth crewed operational NASA Commercial Crew flight and the 13th overall crewed orbital flight of a Crew Dragon spacecraft. The mission launched on 4 March 2024.

The Crew-8 mission transports four crew members to the International Space Station (ISS). Three NASA astronauts, Matthew Dominick, Michael Barratt, and Jeanette Epps, and one Roscosmos cosmonaut, Alexander Grebenkin, were assigned to the mission. Jeanette Epps was previously assigned to Boeing Starliner missions.^[4]^[5]

Mission

Crew-8 is the eighth SpaceX operational mission in the Commercial Crew Program and the 13th overall crewed orbital flight of a Crew Dragon spacecraft.^[7] The mission launched at 3:53:38 UTC on 4 March 2024 (3 March, 10:53:38 pm EST, local time at the launch site).^[8] SpaceX sent the 50th astronaut on this Crew Dragon launch.^[9]

The first launch attempt, the day prior was scrubbed at T−03:25:38 due to elevated winds in offshore areas of the flight path.^[10]^[11]^[12]^[13]

Relocation

To make way for a Boeing Starliner as a part of the Boeing Crew Flight Test that would dock to the forward port of Harmony on 6 June 2024, the crew relocated Crew Dragon Endeavour to the zenith port of Harmony on 2 May 2024, docking to the zenith port at 13:46 UTC.^[16] Boeing Starliner Calypso successfully launched on 5 June 2024 and docked to the forward port of Harmony on 6 June.^[17]

Notes

^ From an orbital dynamics perspective, the forward port is easier to approach, and therefore, new vehicles use this approach for their first docking. The Boeing Starliner Calypso was scheduled to make its first docking to the ISS during the Boeing Crew Flight Test in June 2024; therefore, Crew-8 relocated to the zenith port to clear the forward port for Boe-CFT.
