Fifty years ago, on 18 March 1965, Soviet astronaut Alexei Leonov took the first space-walk.

In 1989 Helen Sharman answered an advertisement she heard on the car radio, which said: "Astronaut wanted. No experience necessary."

She was eventually selected from over 13,000 applicants to be the British member of the Russian scientific space mission, Project Juno - and became the first Briton in space.

She worked with Alexei Leonov and described the struggles of that spectacular walk.

"It's very difficult to work your fingers insdie a swollen-up space suit," said Ms Sharman.
