Space Lander Philae successfully landed on comet – update




The European Space Agency has made history Wednesday with the first successful landing comet. The Philae lander has room Wednesday sent the redeeming signal that the landing was successful.

The Philae lander space has landed on the comet 67P / Churyumov-Gerasimenko and about 17.00 ESA received the signal from the lander. Among the successful landing and the reception was half an hour, so the tension in the organization rose sharply. There could go wrong during landing and Philae could interim no longer adjusted, but that so bad. More about the successful landing can be seen at the special livestream .

Rosetta Philae

The image took Rosetta lander Philae after the space of seven hours began his journey to the comet.

ESA sent after landing a tweet on behalf of Philae on the successful landing in different languages, including Dutch.

ESA has long searched for a suitable landing site on the odd shaped comet for the Philae probe. Ultimately, there is only one place on 67P / Churyumov-Gerasimenko found that could be safely landed and where adequate sunlight is available for the solar panels of the probe. Also, the location, which has been called Agilkia, deemed suitable for carrying out drilling in the comet surface by the cube-shaped spacecraft.

The intention was that the Philae lander to the comet itself would chaining with harpoons, but other than first thought is not successful, the ESA let know on Twitter. The team will try to chain the harpoons again. Otherwise, there is a risk that the lander drifting back towards space; the four-kilometer comet barely has gravity.

ESA has also released the first image that has made Philae landing, at a distance of 3 kilometers from 67P.

Philae on 67P

In the coming months Philae must collect and analyze samples. On the basis of this knowledge, ESA-scientists want to make comparisons with substances on earth. This may include eg whether the theory is plausible stating that meteorite impacts on Earth have played a role in the origin of life. The samples should provide more insight into the origin of the solar system. The end of the mission is scheduled on December 31, 2015.

ESA Rosetta launched on March 2, 2004 from Europe’s spaceport in Kourou in French Guiana. In total, the satellite over more than ten years there done to achieve the comet, including a period in which the satellite has been held in a “hibernation” in order to save fuel consumption. In January this year, the ‘comet chaser’ successfully from sleep awakened . Since the Rosetta probe after a space voyage of more than six billion kilometers on August 6 at the comet has already arrived numerous photos taken from his target. Further, the Rosetta includes a mass spectrometer, a micro-thermometer and an ultraviolet spectrograph. The spectrograph measurements have been carried out in the tail of the comet and the ‘coma’, a shell that occurs when the comet gets closer to the sun.

Update, 18:10: Para added over the harpoons of the lander, which unlike thought not fired successfully.
