| Comet impact: the big end of the "RAM tower" |
"Luo Luo tower" comet orbit probe in September 30th will come to the end of life. But before this, it will play the last song: collected the most detailed image of chapter 67P/ of comet Churyumov Grasimenko, is so far the most detailed image of a comet.
In 2014, after 10 years of long distance travel, by the European Space Agency (ESA) to run the "Lo tower" probe into the first round of the operation of the detector. Two years later, the detector for getting further from the sun and gradually lose energy, ESA scientists decided to end its mission to have a unique style way, which hit the comet surface under control. "The" Luo tower "on the surface of the comet will be sleeping on a thousand years, I like this idea. There is the most suitable place for this admirable satellite." ESA physicist O Laurence 'Rourke said.
The engineers at the European Space Control Center (ESOC) in Darmstadt, Germany, will be in the September 29th World time around 20:50 will be the "Romanian tower" to the impact of the trip to the comet. The target is an area of 700 x 500 meters of the comet head shaped like this "rubber duck", close to the area of a named "Matt" of the 130 meter wide pit, where the release of gas and dust to be known.
The point of impact from Philae, November 2014 landing comet but soon exhausted a lander - the final resting place of about two km. "Maximum design Rosetta" down the track of use of solar energy, by about 13.5 hours of free fall about 19 kilometers, it will have no chance to see Philae. But its last low altitude flight is expected to see the comet in other places of high quality images, may be at a distance of about 15 meters from the surface of the comet to get a high resolution image of millimeter pixel. And the Luo tower, the distance between the comet and the recent no less than 1.9 km. |
