British astronaut Tim Peake has chronicled his space adventures in a book to be published in November.
Hello, Is This Planet Earth?, aimed at readers of all ages, colourfully describes Major Peake's six-month sojourn aboard the International Space Station (ISS).
It includes 150 photographs he took, many of which have not been shown to the public before.
The book title was inspired by the astronaut's famous wrong number call from space, when he misdialled a woman living near his parents in Chichester, Sussex.
Retired teacher Betty Barker (79), thought the call at 11pm on Christmas Eve was a prank.
Major Peake, the first British European Space Agency astronaut on the ISS, flew into space on December 15 last year. He returned on June 18.
The astronaut conducted over 100 experiments and engaged with thousands of school pupils. He was the first UK astronaut to complete a space walk and the first person to run the length of a marathon in space.
