After a hibernation of 211 days ESA could again make contact with Philae. The spacecraft was deposited by the Rosetta satellite on a comet. A scoop.
ENGINEERINGNET – Philae had batteries in order to work for 60 hours, the self. The solar panels were then provide energy but the comet lander ended up in the shade.
The landing worked anchoring systems and the rocket not had to hold the probe in place so Philae bounced around. The video shows a reconstruction of the French space agency CNES.
It was so anxious wait to see if, over time, could again be contacted and that is happening now. The first signs were short and were captured on Saturday night at the ESA European Space Operations Centre in Darmstadt, Germany.
These were the first signals reached Earth via Rosetta because Philae must have been before ‘wake up’ its because there were “historical” data received. Now, it is so to receive matter of all of these data.
Philae is the first probe that sent detailed images of the surface of a comet. It gives more insight into the composition of comets. Before the 100kg weighing device has a range of instruments on board.
COSAC takes samples from the ground up to 20cm depth to analyze the composition of the substance of the planet. Philae has many instruments that should transmit data from the landing location (also in 3D).
In addition, it collects SESAME experiment information about particles and gases in the atmosphere of the comet, the seismic activity and the electrical properties of the surface layer.
Research is also being done to plasma waves generated by the action of the solar wind ejected cometary material. MUPUS examines the thermal conductivity and the temperature profile of the comet dust.
There is still much work to analyze all the data but ultimately, these data also help us understand the origin of the earth, the origin of water on our planet and the universe in general.
