Comet Lander Philae wakes up after a long period without power




Philae, the spacecraft landed last year in spectacular fashion on a comet, is again awakened. After a long period with empty batteries again sun seems to fall on the solar panels, making it possible investigation can be resumed.

The European Space Agency made ​​known Philae again made ​​contact, which means a big boost for the research program. Saturday received the European Space Operations Centre in Darmstadt about 300 packets of the comet lander; The first sign of life in months. There are still about 8,000 packets into memory and ESA hopes to be sent to the following contact. It must also be clear what has been happening in recent days.

Data show that the circumstances on the comet are good. Philae has a temperature of -35 degrees Celsius, and has enough power available in order to perform tasks. What will be done exactly, which is not yet published. It is the first contact since the Philae makes himself switched off on 15 November due to lack of power. The ESA had expected to Philae previously would awaken again. Incidentally revealed the information received that the lander had already become active again, but had not yet had an opportunity to get in touch with the earth.

Philae landed on November 12 at 67P / Churyumov-Gerasimenko. It is the first time that it has successfully lands a spacecraft on a comet: such an operation is complicated because small objects such as comets have little gravity. The landing of Philae therefore was not entirely according to plan. By bouncing the landing vehicle had landed a few hundred meters from the target pitch, which had a negative impact on the amount of sunlight falling on the panels.
