A pair of spaceman wholaunched aboard Boeing ’s Starlinerspacecraft in June for a 10 - mean solar day misstep to theInternational Space Station(ISS ) will now spend at least nine months in space , afterNASAannounced yet another delay to their counter flight .

NASA saidin a blog post Tuesday(Dec . 17 ) that the next work party swap to the ISS will go on no earlier than later March 2025 . The Crew-10 mission will launch four crew members to the quad station . It was originally scheduled for February , but NASA andSpaceXhave delayed the launch for make out a new Dragon spacecraft for the commission . The Dragon space vehicle is the private spaceflight ship’s company ’s crewed vehicle that can carry up to seven astronauts at a time into low - earth area .

" Fabrication , fabrication , testing , and last desegregation of a unexampled spacecraft is a painstaking endeavor that requires great tending to detail,“Steve Stich , the director of NASA ’s Commercial Crew Program , say in the web log post .

The hold , however , means an surplus calendar month in space for NASA ’s Butch Wilmore and Sunita Williams — the two astronauts who fly to the post aboard Boeing ’s Starliner bunch - delivery vehicle earlier this year . The mission was expected to last a little more than a hebdomad , but the craft experiencedissues with its thrusterson its approach to the ISS . This lead to a three - month delay in the spacecraft ’s coming back as NASA tried to figure out the problem . Ultimately , the bureau sent the spacecraft back to Earth without its gang . It shoot down in Septemberwithout incident .

Wilmore and Williams have unknowingly become long - term residents of the ISS , though their trip isnot threatening any records . For example , astronaut Scott Kelly ride out aboard the ISS for 340 days between 2015 and 2016 as part of a twin field of study — his astronaut matching brother Mark stayed on Earth so researchers could compare the two and learn about theimpacts of space on wellness and physiology . In 2023 , cosmonaut Frank Rubiospent a year straight in orbit , the first American to do so . ( Rubio ’s length of stop was also unintentional , as his Soyuz spacecraft sprung a leak . ) Six other people have spend more than a year in blank space .

The Crew-10 mission will carry NASA astronaut Anne McClain and Nichole Ayers , Japan Aerospace Exploration Agency astronaut Takuya Onishi , and Roscosmos cosmonaut Kirill Peskov to the ISS . After a handover period , Williams and Wilmore , along with NASA cosmonaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov will return to Earth . The ISS was resupplied in November , according to NASA , including " especial items " for the spaceman to celebrate the holiday in space .
