Former Army Air Corps pilot Major Tim Peake has spoken to Forces TV from space in his first interview from the International Space Station.
Tim blasted off from Earth earlier this week, marking the start of a six-month mission in space.
In a personal message to the forces, he wished "everybody who's deployed on operations all the very best of luck and a happy Christmas and a happy new year."
Our reporter Rob Olver asked how Tim's mission in space compared to a military tour of duty. The former Apache pilot said:
"I think the isolation from family and friends is fairly similar and also the length of time that you're away."
"You just have to get into that mental mindset. Both you and your family back home that you're not going to see each other for a long time."
"Once you've achieved that then it's a case of just focusing on the mission ahead and looking forward to when you'll be reunited with your family."
Tim finished by sending a message to the Army Air Corps, Middle Wallop and the Forces at large. He said:
"I would like to say a huge thank you to everybody at the Army Air Corps and Middle Wallop"
"There was both a launch party celebration going on and also I received a fantastic good luck message."
"Thank you to everybody who has supported me I look forward to sharing this mission when I get back as much as I can with you."
