Exploring space

To mark the 50th anniversary of the Moon landing in July 1969, five personal accounts of landmarks in space exploration. We hear from an Apollo flight controller about the moment Neil Armstrong stepped onto the lunar surface, and from one of the astronauts who survived the Apollo 13 near disaster. Plus how Laika the dog became the first living creature in space, the pioneering woman cosmonaut Valentina Tereshkova, and Britain's attempt to put the Beagle 2 lander on Mars.PHOTO: Buzz Aldrin on the Moon in July 1969 (Getty Images)
