Today is the 25th anniversary of man's first steps on the moon. To mark this anniversary, CBBC are dedicating the afternoon's programmes to the moon.
There are films telling the story of the space race as well as more light-hearted items such as the top ten space songs and a balloon and rocket release from the roof of Television Centre.
Answering questions on space are Patrick Moore and Helen Sharman, and former astronaut Buzz Aldrin describes what it was like on the moon.
Hosted by Zoe Ball and Gareth Jones.
