European Space Agency aiming for historic comet landing

Space engineers are making final preparations for the historic landing of an small probe on a comet more than 300 million miles (510 million km) from Earth.

The European Space Agency's Rosetta satellite will drop the probe on to Comet 67P/Churyumov-Gerasimenko from an altitude of 20km.

It is hoped analysis of the comet will unlock clues about the origins of the solar system and life itself.
