SpaceX Crew-8 is the eighth crewed operational NASA Commercial Crew flight and the 13th overall crewed orbital flight of a Crew Dragon spacecraft.^[4] The mission launched on 4 March 2024.^[5]

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.^[6]^[7]

Mission

The eighth SpaceX operational mission in the Commercial Crew Program launched at 3:53 UTC on 4 March 2024.^[9] SpaceX sent the 50th astronaut on this Crew Dragon launch.^[10]

Launch attempt

Following delays due to unfavorable weather conditions in offshore areas of the flight path,^[11]^[12] the first launch attempt was scrubbed at T−03:25:38 hours due to elevated ascent winds (times are UTC).^[13]^[14]

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 June 6, 2024, the crew relocated Crew Dragon Endeavour to the zenith port of Harmony on May 2, 2024, docking to the zenith port at 13:46 UTC.^[17] Boeing Starliner Calypso successfully launched on June 5, 2024 and docked to the forward port of Harmony on June 6.^[18]
