Overview

  • Crew-10 undocked from the ISS on August 8 at 6:15 p.m. ET and splashed down off California at 11:33 a.m. ET the next day, concluding a 147-day mission.
  • Commander Anne McClain, pilot Nichole Ayers, JAXA astronaut Takuya Onishi and Roscosmos cosmonaut Kirill Peskov returned safely while the newly arrived Crew-11 team remains aboard the station.
  • During their five-month stay, the crew completed more than 200 microgravity experiments in fields ranging from plant biology to human physiology.
  • NASA plans to continue relying on SpaceX for upcoming rotations until Boeing Starliner completes technical recertification.
  • SpaceX’s shift to Pacific splashdowns helps safeguard populated areas by dropping Dragon trunks over uninhabited ocean regions.
