Tim Peake faces physical and mental issues after mission

Tim Peake faces physical and psychological challenges after landing, according to French astronaut Jean-Francois Clervoy.

Clervoy - who flew in space three times in the 1990s - told BBC News: "You feel very, very heavy... It takes about a month to feel back to normal."

And he said it was important to plan for after the mission: "When you come back, the whole big challenge is behind you... it's like a big void in front of you."
