Mission was: to prepare landing

Mission was: to prepare landing

This landing will take place in October and will be a first. In 2005, the spacecraft Deep Impact had dropped an impactor on the comet 9P / Tempel-1 and in the same year, Hayabusa , the Japanese space agency, tried landing on the asteroid Itokawa, with mixed success, both the maneuver is difficult.

To file Philae, Rosetta will skim Chury less than 5 km. A dangerous skimming as a comet "degassed" heated by solar radiation, the surface ejects water vapor, ice chips and dust. This activity should be accurately estimated by engineers at ESA before diving Philae.

The module will then 100kg avoid another risk: bounce into space, never to return if the impact on the body to the very low gravity is too strong. Philae will rely on its claws completing the end of its three legs to hang. The Rosetta mission will then take a new turn, more scientific than technical: it is the history of our solar system that astronomers hope to read in comets in general and in particular ... Chury

But this is another story that we will tell you in due time. For now, experts scrutinize the raw images. First informed comments tomorrow. Check back Futura-Sciences, there will be new!
