“Phil” is ready to land on the comet Churyumov-Gerasimenko in order to explain the emergence of life

November 12, the evening will be a crucial part of the mission “Rosetta”.
At midnight on November 13 will be one of the most anticipated events in the world of science. On the comet Churyumov-Gerasimenko, landing module “Phil” released “Rosseti”.
If everything is passed successfully, it will be the first ever soft landing on a comet nucleus. The probe will take samples from the surface of the cosmic body and give them to the Earth. Scientists believe that the information obtained will shed light on key issues, how on Earth did the water and life began, whether life can travel in space by comets?
Event comparable in scale to the first launch of an artificial satellite or a man in space.
THE REFRIGERATOR WILL LAND ON A RUBBER DUCK
Imagine the picture. “Phil,” which is the size of a refrigerator, need to land on the comet, which is of the form “a children’s rubber duck” and its surface is many cliffs, notches, ledges and slippery surface.
An extremely difficult task. So “Phil” touches the surface of the comet at a speed of 1 meter per second, using harpoons and screws to fixate.
The landing site chosen scientists in September, after Rosetta reached the comet, and began to revolve around it. Scientists have found the most appropriate point, calling it Agilkia in honour of the Egyptian island located on the Nile river. It is on the surface a small “head” of the comet.
If you don’t manage to land on “Agility”, that is, the spare area for planting.
The beginning of the separation module is planned at 20:35 o’clock UTC (in Kiev – 18:35) 12 Nov. Touch the surface of the comet’s going to happen seven hours later.
– The moment of separation is fixed in time and space, speed and altitude, and where would the “Rosetta” was, we should reach this point at the required time, – the Director of the flights of ESA, Andrea Accomazzo.
Even the smallest mistake in the mission control center, located in Darmstadt, Germany, will lead to significant deviations and the failure of a Grand mission.
While Rosetta orbited the comet, scientists have updated their knowledge on a celestial body, reported the website of the website www.dialog.ua
The cycle of rotation of the comet: 12.4 hours.
Mass: 10 billion tonnes.
Density: 400 kg per cubic meter (about the same as some woods).
Volume: 25 cubic km.
Color: Coal – judging by its albedo (the reflectivity of the surface of the body).
The launch of the “Rosetta” the European space Agency occurred on 2 March 2004. Breaking over 6.5 billion kilometers, as a result of complex maneuvers, the media came to the comet in August this year at a distance of about 450 million kilometers from Earth.
OF THE COMET CHURYUMOV-GERASIMENKO SEEN A UFO?
It seems that the comet Churyumov – Gerasimenko exploring not only the Terrans. Very much reminiscent of a flying saucer object photographed celestial wanderer 10 September 2014. The picture was taken by the navigation camera mounted on the probe “Rosetta” – the automatic spacecraft of the European space Agency (ESA), which is now near the comet. At the time of the capture probe was located at 27.8 kilometers from it.
UFO drew the attention of the ESA. And commented on his appearance on its website.
