Four astronauts arrived at the International Space Station on Thursday after an eight-hour journey from Earth, completing the fastest crewed trip to the orbiting laboratory by a US spacecraft.

The astronauts launched aboard a SpaceX Dragon capsule after a three-week delay caused by repairs to a leaking fuel system. Thick clouds threatened to postpone the launch again, but weather conditions improved enough for the mission to proceed from Cape Canaveral Space Force Station in Florida.

The short journey was possible partly because of the station’s position at the time of launch. Although the astronauts are scheduled to spend about six months aboard the space station, their trip there was the quickest recorded by SpaceX or any US space programme, including NASA.

Commander Jessica Watkins became the first Black woman to lead a crew into orbit. The geologist previously worked with NASA’s Curiosity Mars rover programme and spent an extended period aboard the space station in 2022.

“Thanks for an amazing ride,” Watkins told mission control after the launch.

The other members of the crew are NASA astronaut Luke Delaney, a retired Marine, Canadian astronaut Joshua Kutryk, a Royal Canadian Air Force colonel, and Russian cosmonaut Sergey Teteryatnikov, a former submariner. All three are making their first journey into space.

The crew will replace four astronauts who have been living aboard the International Space Station since February.

The mission is SpaceX’s 13th crewed flight for NASA, excluding its crewed test flight in 2020. The astronauts have embraced the Crew-13 designation, with the mission patch featuring a reference to Apollo 13, the 1970 lunar mission that ended with its crew safely returning to Earth after a serious in-flight emergency.

The number 13 featured repeatedly during Thursday’s launch preparations. The astronauts travelled to the launch pad in black Tesla vehicles with licence plates reading “Lucky 13”. They also carried a small crocheted golden dragon called Lucky, which wore a four-leaf clover.

Watkins later joked from orbit that the crew had brought some extra luck with them, describing the four astronauts as among the “luckiest humans on or off planet Earth.”

Kutryk’s mission carries a particularly personal milestone. His wife, Heather, is expected to give birth to their third child in late November, making him the fourth man to become a father while in orbit.

The Canadian Space Agency has said it will support Kutryk and his family during the birth. NASA has previously helped astronauts remain connected with family members during major events on Earth.

SpaceX also conducted multiple launches on Thursday. Hours after the crew mission, the company launched a Falcon rocket from California carrying more than 100 small satellites. Another Falcon launch from Florida was scheduled later in the day with a classified National Reconnaissance Office satellite.

The launches came during a busy week for SpaceX, following the first orbital flight of its Starship vehicle.
