European researchers for the last time trying to contact the lander Philae, which sits on a comet 67P. Communications does not have half a year.
dramatic landing on a comet took place over a year ago. After many attempts lander Philae is released from Rosetta sat down on the surface 67P. Not everything went according to plan, and although contact established, since July the lander is silent.
Now experts from mission control in Darmstadt, Germany sent a special command Philae is to shake off the dust that solar cells could download the appropriate amount energy.
The chance to recharge the batteries fall every moment, because the comet 67P moves away from the sun. Attempts to establish a connection to be made by the end of January. Then the lander will have to be written off.
In October last year, Rosetta space probe has discovered molecular oxygen to comet 67P. It completely surprised astronomers.
Yahoo on a comet is present as free particles. So it should not be, because oxygen should tie up with other elements.
FILM: In June, after seven months nap, Philae lander spacecraft snapped and sent to Earth data collected on a comet. Scientists have just announced that the comet’s surface Philae has detected 16 organic compounds. As well as water vapor, carbon monoxide and carbon dioxide. Some of these compounds are the basis of life. And their existence may be an indication dot. Origins of the solar system.

The researchers when they saw the new data they thought it was a mistake, says the BBC Professor Kathrin Altwegg from the Swiss University of Bern. – Nobody saw it coming, and nobody knew where it came from there the molecular oxygen – says Altwegg.
Comets are very old and much talk about the history of the cosmos. Researchers believe that a long time ago on a comet 67P oxygen simply froze. This in turn suggests that the formation of our solar system was not sudden, as was believed until now, only much quieter.
Earlier on comet 67P discovered water, but a little different than that on Earth, and organic molecules, which are the basis of life. Scientific publication publishes the weekly magazine “Nature”.
