How Crew-13 set a U.S. launch-to-station speed record

NASA astronauts Jessica Watkins and Luke Delaney, CSA astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov docked at the Harmony module at 7:05 p.m. EDT.[3] The journey took 7 hours and 55 minutes from launch to docking, compared with the 15-to-24-hour transfer typical of Crew Dragon missions.[3][6]

Why it matters

A shorter rendezvous reduces the time astronauts spend confined in a capsule, while Crew-13’s roughly six-month stay will support station maintenance and research into microgravity, astronaut health, disease treatments and food production.[6]

Key insights

  • Crew-13 launched more than two weeks later than expected after an oxidizer leak in Dragon Grace’s propulsion system prompted additional checks and tests.[6]
  • Grace previously carried the private Axiom-4 crew to the station.[6]
  • Jessica Watkins became the first NASA astronaut to launch aboard Crew Dragon twice.[6]
  • Crew-13’s arrival begins departure preparations for Crew-12, whose mission was extended by the launch delay.[6]
