Abandoned ESA Comet Lander will transmit again

Abandoned the ESA research unit land on the small comet Philae in February. Now they have learned the consequence and the communication module ESS on the Rosetta mother probe for always switched off. Philae has can spark but only around 60 hours from the surface of the Comet Tan. Still has written the little guy in space history.

It is a farewell forever: yesterday, on Wednesday, the 27th July 2016 at 11 o’clock, the Rosetta mission scientists have ESS electrical support system at the European Space Agency ESA communication module (on) the cometary probe Rosetta to comet-lander Philae permanently switched off. Of a cubic small box had written on 12 November 2014 space history: after a journey of more than ten years Philae and away 510 million km from Earth to comet 67.

Large fan-base land without demage

The Comet with a diameter of four kilometers and the appearance of a cute duck got immediately missed by a large fan base all over the world the affectionate abbreviation of “Tan” and that although he stinks to heaven.

Because the perfume, which has to be settled in the Comet, seems to spring from hell: rotten eggs, horses urine and biting formaldehyde. Just as well that Philae was unmanned to the comet’s surface.

Seven months in the cryogenic sleep

Unfortunately, not gently landed on the sunny side of the smelly bathroom duck Philae, on the comet’s surface, until he then probably tipped on the side in the shade of a survey. As a result, Philae fell after only about 60 hours scientific work on 15 November 2014 1:15 due to acute shortage of energy in a seven-month cryogenic sleep.

The ESA Comet researchers not exercise hope, once again will get contact with the lander.

Mother probe draws loyal until today TAN orbits

Because Tan traveled on its orbit of the Comet towards the Sun. The radio silence lasted until June 13, 2015. On a Saturday night, Philae volunteered but in fact again when his mother probe Rosetta, which attracts their orbits to Tan faithful until today. 85 seconds took the radio contact, where Philae could transmit 300 data packets. A month later, on the 9th July 2015 the small Lander radioed a final signal from the surface of the smelly bathroom duck.

Terminated mission Philae

“It was a unique mission with Philae it was not only the first time that you ever put on with a lander on a comet’s surface. We have fascinating data, with which we can work for many years”, says Prof. Pascale honorary friend, Board Chairman of the DLR and participating scientist on the mission.

Now, the mission with Philae is really finally finished, even if the lander should pay once again. Rosetta can no longer hear him.

Rosetta bell tolls in September

Because the mother probe requires all energy for himself alone: your mission is still not over. Meanwhile, Tan is approximately 520 million kilometers from the Sun with the Rosetta probe orbiting him. The solar sail of probe can generate hardly any energy. Therefore, Rosetta to land on September 30 in a spectacular kamikaze action on the comet’s surface. In the last days and weeks of their probe life, she should make particularly exciting close-ups of Tan and send earth mother.
