Astronaut Tim Kopra describes his first ever spacewalk

Tim Peake is to carry out the first ever spacewalk by a British astronaut, Nasa has confirmed.

Mr Peake and Nasa astronaut Tim Kopra will venture outside the International Space Station (ISS) on 15 January to replace a failed voltage regulator.

Colonel Kopra described his first ever spacewalk: "It's a lot for your mind to process, that you're outside, in a vacuum, looking down at our planet, in the black of space."
