The first official British astronaut has been chosen to go into space in 2015.
Major Tim Peake has been in training all over the world in preparation for the trip.
We asked if being an astronaut is something you'd like to do.
"I absolutely love space and would like to be the first young teenager to discover a new planet or maybe a living thing. However, it could be dangerous as I might get lost or run out of oxygen!"

"I would absolutely love to go to space. We studied about space and astronauts in science this year and I loved it. I think space is amazing and it would be a great experience, if maybe, one day I could go to space. It would be cool to be out of this world and look down on earth as well as check out new planets. I just love the solar system."

"We would be a little scared, but we would be excited because the moon would be shiny and a little bouncy. We might see aliens which would be fun. We would like to see the stars close up. We would like to see the craters on the moon. We could float in space and do forward and backward flips. We might get hit by meteors and get sucked into a black hole!!"

"We would really like to go into Space and visit the Moon! We would be worried and excited about the possibility of meeting Aliens. It would be really cool to jump up and down on the Moon. We would like to know what our footsteps would feel like on the Moon and we would like to be able to see stars close up! We would worry about running out of fuel but we would look forward to going in a rocket."
