Lift-off for Nasa's LADEE Moon mission

7 September 2013 Last updated at 05:08 BST

The unmanned LADEE probe has successfully lifted-off from the Wallops rocket facility on the US east coast to investigate the atmosphere that surrounds the Moon.

Scientists are hoping that the probe will help them understand how the so-called exosphere behaves - the most common type of atmosphere in the solar system.

LADEE stands for Lunar Atmosphere and Dust Environment Explorer.
