Nasa says that the astronauts stuck on the space station will have to wait even longer to get home.

A new crew needs to launch before Wilmore and Williams can return and the next mission has been delayed by more than a month, according to the space agency.

Nasa’s next crew of four for the ISS was supposed to have been launched in February 2025. The capsule carrying that crew was due to be the one bringing Butch and Sunni home, as well as NASA astronauts Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov as part of the normal crew rotation.

But there has been a delay by the private sector firm SpaceX in preparing a brand-new Dragon capsule for the mission. That is now scheduled for flight readiness no earlier than late March.
