Comets Jager Rosetta successfully come out of hibernation

The Rosetta spacecraft of ESA has woken up after a hibernation of more than 31 months. The onboard computer launched in 2004 ‘comet hunter’ should be largely eliminated because the distance was too great for the sun.

Rosetta , a project that ESA has cost approximately € 1 billion as a destination, the comet 67P/Tsjoerjoemov-Gerasimenko. ESA wants to bring the satellite into orbit around the comet. From 30 km altitude, then must be a lander, Philae called, on the ice cube bags and let himself be tied down to the surface. Philae will there make pictures and perform various scientific measurements. This feat should be. Conducted from August step by step

To get to the comet the spacecraft to make a detour and will be the total distance to be 7 billion miles. Rosetta should include use of the gravity of Mars and the Earth to generate sufficient. Momentum

Because it was far away from the sun and the solar panels generated enough power, therefore, during part of the journey Rosetta various non-essential elements of the satellite for a period of 31 months were eliminated. Meanwhile Rosetta nearer the sun came and highly efficient panels, which have been developed by the Dutch company Dutch Space can be used again. The ESA is Monday at 19:18 via Twitter to know that a signal to the Rosetta mission leadership in the German city of Darmstadt sent and it has come out. hibernation
