Valerie Jamieson from The New Scientist came in to discuss astronauts with Jonny Gould and Ash.
The editorial content director reveals what she thinks it's like being in space.
"You have to be [charming] because, when you think about it Tim Peake was up there for six months on the International Space Station," she said. "This is like the Big Brother house – an extreme version of it.
"You can talk on the phone, there was a famous incident where Tim Peake called up the wrong number.
"Back in 2008, the European Space Agency held an open competition and said anyone can apply to go in to space, and it was Tim Peake who won that competition.
"Mike Kelly, who’s a NASA astronaut and piloted the space shuttle couple of times said: 'oh it's just a job, you do all this training and you prepare for every eventuality'."
She also discussed time travel, but explained you can't travel faster than the speed of light.
"You wouldn't be able to go back in time that way, but some people are talking about other ways of time travel, worm holes and things like that.
"Obviously when you're looking out in the night sky you can see the moon, you can see a lot of the planets and these stars that we see are billion of light years away, so space is out there."
