The Philae-ruimtelander by ESA’s satellite Rosetta and released. Philae should be landing on the badeendvormige comet 67P/Churyumov-Gerasimenko. This would be the first successful komeetlanding a fact. Philae will take samples of the comet.
The landing of the spacecraft caused a lot of stress at ESA, partly because of the huge distances make for a delay of almost half an hour between the komeetlander and the room. Although the lander to five about half past ten all was released, could the team that only four in ten verify. Also, the Philae probe by the delay is not more to be adjusted now by the Rosetta is released. The landing takes is expected to be around seven hours and can be followed via a special livestream.
The ESA has long searched for a suitable landing spot on the irregularly shaped comet for the Philae probe. Eventually, there would be just one place on 67P/Churyumov-Gerasimenko have been found where a safe landing could be and where there is adequate sunlight available for the solar panels of the probe. Also the location, which Agilkia is named, are considered suitable for the execution of holes in the komeetoppervlak by the cube of the spacecraft.
Because it is unclear what type of surface 67P/Churyumov-Gerasimenko and the four-kilometer comet in addition, almost no gravity, chains Philae on the komeetoppervlak fixed with the help of harpoons. The coming months should Philae monsters begin to gather and analyze. On the basis of this knowledge, like ESA scientists make comparisons to substances on earth. This may include consideration of whether the theory is plausible in which it is stated that meteorite impacts on earth have played a role in the emergence of life. Also, the samples should provide more insight into the origin of the solar system. The end of the mission on 31 december 2015 as planned.
The ESA launched Rosetta on march 2, 2004 from the European launch base in Kourou, French Guiana. In total, the satellite has more than ten years for the comet to reach, including a period in which the satellite into ‘hibernation’ is held to save fuel. In January of this year was the ‘kometenjager’ successfully from sleep, awakened. Since the Rosetta probe after a space flight of more than six billion kilometers on August 6 at the comet arrived he has already had plenty of photos taken of his target. Furthermore, it contains the Rosetta among other things, a mass spectrometer, a microwave thermometer and a ultraviolet-spectograaf. With the spectograaf all measurements are carried out in the tail of the comet and the coma, a shell that occurs when the comet gets closer to the sun.
