• Question: I heard on the news this morning that Tim Peake will be arriving back on Earth soon so I would like to know what happens differently to your body in space compared to being on earth? Because I have read somewhere that too long in space can weaken your bones. Thanks

      Hi Quinn Atkins,

      Yes space is very difficult for the human body and it adapts even after a shortexposure to microgravity.

      The main negative effects of spaceflight on the human body are that the muscles get smaller, the bones get weaker and your eyesight can get worse!

      To try and stop all the bad things associated with weightlessness in space astronauts exercise 2 hours every day. They cycle, run and do weight lifting in space but even with a lot of exercise astronauts still come back worse than when they left!
