  Spacecraft set to land on comet
Updated 20 February 2004, 16.09
Comet
Scientists from the European Space Agency outlined a 600 million mission to land on a comet's surface in 2014.

The Rosetta craft will begin on a 10-year journey to the comet Churyumov-Gerasimenko on 26 February from French Guiana in South America.

Comets, which are basically dirty balls of ice, may hold clues about how the solar system and life on Earth began.

Dr Ian Wright, a scientist on the team, said: "It's possible that the water on Earth was brought here by comets."

It'll be the first time any craft will have landed on a comet.

The mission was due to launch in January 2003, but an Arianne-5 rocket like the one set to carry Rosetta, exploded.

That meant all Arrianne-5 missions were grounded.

Once Rosetta reaches the comet, a smaller craft called Philae will latch onto it using harpoons.
