Nasa astronauts Butch Wilmore and Suni Williams recently returned to Earth after a longer-than-expected nine months on the International Space Station (ISS). And when the astronauts emerged from their space craft they were helped on to a stretcher, which is standard practice after spending so long in a weightless environment.

The BBC’s Caroline Steel has been looking into how going into space impacts the body. She talks us through how muscles, bones and even vision are affected, and how astronauts can limit any long-term damage. Peggy Whitson holds the world record for the woman who has spent most time in space - 675 days. She explains the challenges of lifting weights while in zero gravity.
