Rosetta accidentally made the “farewell” the missing Philae probe

On one of the images made by a camera aboard the space probe Rosetta (“Rosetta”), experts from the European space Agency have discovered the lander Philae (“Fily”), the exact location of which still remained a mystery. The first ever probe landing on a comet, was made on 2 September, but published only recently.

The spacecraft “Rosetta” probe “FILA” on Board on 2 March 2004, was launched to comet 67P/Churyumov-Gerasimenko in the framework of the project implemented by the European space Agency in collaboration with NASA. In early 2014, the spacecraft approached its target, and on November 12 Philae has made the first ever soft landing on a comet surface. However, although the landing was soft (in the sense that it did not lead to any damage of the probe), it was not as planned. Initially, the unit made a landing at the point at which it was planned, however due to the fact that for some unknown reason did not work installed on it harpoons, to gain a foothold failed. As a result, the apparatus took on a much worse sunlit part of the comet, and given the fact that it worked on solar batteries, the undesirability of such a turn of events was obvious.

When the apparatus is no longer enough energy, the experts have translated it into “sleep mode” from which he was released in June 2015. However, after re-enabling the device worked for less than a month and the signals coming from it stopped flowing completely. July 26, the official Facebook page of descent of the probe in Twitter there was written “on behalf of” Philae message, in which he symbolically said goodbye to the Ground. Two days later, the “Rosetta” was disabled unit, used for communication with the apparatus.

Although not entirely successful landing, the probe was unable to perform all of the tasks that stood in front of him, he still allowed us to collect a lot of information about the comet, in particular, to detect therein an organic compound and gradually evaporates as oxygen and a considerable amount of water ice. Managed with a probe and clarify the age of the comet — he is supposed to be approximately equal to the age of the Solar system.

A new picture that suddenly allowed us to understand exactly where the lander can become a kind of “finishing touch” in the history of the mission, until the end which left very little time: September 30, Rosetta will be sent to the comet, will do on the road the last few pictures, and then “subscribe” to the “FILA” and even if I didn’t crash-land will be permanently disabled.
