 Rosetta lander Philae found the  missing for months slept on the comet 67P  Churyumov-Gerasimenko

Found after one year Philae, or the lander landed on the comet’s surface last November 2, 2014, and that some time gave no more signs of life; the lander, in fact it was finished in the shelter of a rock, most likely had no more energy and his destiny was to “die” very far from the place where it was created, or the Terra.Invece, after some time, the lander has come to life thanks to the equipment on board the probe Rosetta , who finally managed to locate the lander hidden and wedged into a crack on the surface of the comet 67P / Churyumov-Gerasimenko.

the latest communications from the lander exactly dated back to last July 2015, and finally to less than one month after the conclusion of the European space Agency’s mission, the high resolution camera of Rosetta probe Osiris, seems to have managed to capture the image of Philae. The probe sent last Friday of the images quite clear, taken by the narrow-angle cameras Osiris, when Rosetta was among others at a distance of 2.7 Km from the surface ; these images showed the main body of the lander and two of its three legs.

“With even just a little month of mission in front of us, we are delighted to finally be able to have an image of Philae, and to see him in a surprising level of detail,” says Cecilia Tubiana of the mission teams, the first person who saw the Philae during downloading of photos .It is a rather interesting news as it means finally have the information that we were missing to frame in the right context now that we know what land it was, the data collected from the lander during the three days of scientific operations , added the Rosetta project scientist Matt Taylor ESA. the probe Rosetta also will turn her down on the comet’s surface, the September 30th just when is switched to the smaller lobe of comet 67P, where it will make its descent to extinguish definitively tools and communication with Earth.

the last remark went up again really to November of two years ago when the lander was released from the Rosetta spacecraft – which he had transported for millions of kilometers – to reach the surface of 67P; it seems that the landing was not optimal and it is impossible to photograph right away the lander had led to analyze different parameters sent to the probe and the probe to Earth to reconstruct the trajectory of Philae as well as its exact landing point was until a few days ago sconosciuto.Non seem to be, however, hopes to revive the lander, because after a long time it seems that the instruments being affected.
