Astronauts on the London Underground!

Mock astronauts take the Tube in London to launch The Lynx Space Academy competition to find one UK winner and 21 others from around the globe who will be sent to where only a few elite have gone before. 

Buzz Aldrin has launched a once-in-a-lifetime chance for an average Briton to blast into orbit. 

Aldrin, the astronaut and pilot of the historic Apollo 11 spacecraft which landed on the moon in 1969, said: Space travel for everyone is the next frontier in the human experience.
