Tim Peake webchat: your questions answered on travel adaptors, running a marathon and hiccuping – in space

The British astronaut answered your questions on whether you can get a cold in space, why you can't see Brexit from the ISS, the time he saw strange flying objects and why he wants to go to Mars

That's all for today!

Thanks for all the brilliant questions, I've really enjoyed answering them and sorry to those of you who didn't get an answer. There are loads more answers in my new book Ask An Astronaut and proceeds go to the Prince's Trust.

JacandJill asks:

What was the hardest part of the selection process for you? From Lucy age 9.

The selection process took a year and covered many different areas. Some of these are these that you simply cannot train for such as your medical condition and psychology. However, some areas such as communication skills and teamwork are things that you can practice and get better at throughout your career. I found the hardest part of selection were all the tests we had to do on the very first day. This covered areas such as maths, science, language, concentration, memory, spatial awareness and it was a very stressful day. At the time I had no idea how well I had done, but when I was told I'd passed I knew that for me that was the most difficult hurdle out of the way.
