SpaceX Crew-8
SpaceX Crew-8 was the eighth crewed operational NASA Commercial Crew flight and the 13th overall crewed orbital flight of a Crew Dragon spacecraft. The mission launched on March 4, 2024.
The Crew-8 mission transported 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.
The Crew-8 mission was extended to accommodate problems encountered by the Boeing Crew Flight Test during its mission. The crew outfitted the Crew-8 capsule to accommodate two extra astronauts if an emergency occurred prior to Crew-9 docking on September 29, 2024.
Crew-8 was the eighth SpaceX operational mission in the Commercial Crew Program and the 13th overall crewed orbital flight of a Crew Dragon spacecraft. 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). SpaceX sent the 50th astronaut on this Crew Dragon launch.
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.
Note: times are local to the launch site (Eastern Daylight Time).
To make way for a Boeing Starliner as a part of the planned May 6, 2024 Boeing Crew Flight Test that would dock to the forward port of Harmony, 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. After several delays, Starliner docked on June 6, 2024. Boeing Starliner Calypso successfully launched on June 5, 2024, and docked to the forward port of Harmony on June 6.
The Boeing Crew Flight Test mission docked with the ISS on June 6, 2024, after experiencing anomalies with its thrusters. Its crew of two remained on the ISS for an unplanned extended stay, while NASA and Boeing evaluated the problems. NASA decided that the uncertainties were too high to have the crew return to Earth on Starliner, so they sent the Crew-9 mission to the ISS with a crew of two, and the Starliner crew then returned to Earth with Crew-9 in March 2025, while Starliner undocked from the ISS and made a successful uncrewed return to Earth in September 2024. This was necessary, because the ISS has only two IDSS ports shared between Dragon and Starliner. However, each ISS crewmember needs a contingency "lifeboat" in the event of an ISS emergency, and uncrewed undocking of the Starliner would leave its crew without a lifeboat. Therefore, NASA directed the crews to install two extra crew positions in the cargo area of the Crew-8 capsule to provide the lifeboat function after Starliner undocks and before Crew-9 docked. Until Crew-9 arrived, they moved to SpaceX Crew-8, their temporary emergency evacuation spacecraft, and subsequently to Crew-9.
