Tim Peake, the British astronaut, was forced to leave an answer phone message for his parents after calling them from the International Space Station to find that they had "popped out".
Nigel and Angela Peake, who travelled to Kazakhstan to see the rocket launch last week, said they had gone out for an hour to visit their daughter when Major Tim decided to "phone home" from space.
He was forced to leave a message on their answer phone instead.
His father, Nigel, 74, of Westbourne, West Sussex, told ITV News: "It was quite surreal. We'd popped out for about an hour to see our daughter who lives nearby, came home to an answer phone message, 'Hello, this is your son from the International Space Station'.
"We're out when he calls! That message is going to stay there in perpetuity, I can assure you."
