One of the NASA astronauts stuck in space has spoken about the concerning effects their long wait has had on their body, with doctors issuing a warning

NASA’s two stuck astronauts are just a few weeks away from finally returning to Earth after nine months in space. Butch Wilmore and Suni Williams have to wait until their replacements arrive at the International Space Station next week before they can check out later this month.

The two astronauts arrived on the International Space Station (ISS) in June, for a planned eight-day stay above the Earth’s atmosphere. But a fault with the Starliner capsule discovered during the outward flight has forced them to remain onboard since the summer.
