Apparatus Philae descended on the comet and survived landing - VIDEO PDF Print E-mail

To land a spacecraft on the surface of a comet almost as hard as a shot bacteria. But jewelry work still managed to hold the leaders of the mission "Rosetta", which was lowered to the surface of the comet Churyumov-Gerasimenko lander "Phil", despite the fact that the active shutter system unit was defective when it is energized. With this breakthrough European scientists also congratulated NASA.
"Apparatus" Fila "descended on the comet and survived the landing. He sat in a strictly planned place and, of course, on the very same comet, for which we hunted from the beginning of the mission," - says Jean-Jacques Dordain (Jean-Jacques Dordain) , Director General of ESA.

planting machine could not be considered completed until until "Phil" did not establish a communication channel with the orbiter "Rosetta" on which he flew to the comet and with the help of which will now be to communicate with Earth.

As it turned out after the connection between the two devices, "Phil" at least three times bounced off the surface of the comet from the fact that the harpoons were not able to fix it right the first time. These alarming news came a few hours after it became clear that the robot is already on Churyumov-Gerasimenko surface.

Apparatus "Fila" managed to convey images of the primary landing (photo ESA / Rosetta / Philae / CIVA).

Primary signals transmitted by the ground station apparatus, testified that "Phil" loaded his "feet" 4 centimeters deep into the surface of a celestial body, suggesting that the upper layer of a comet is composed of soft rocks. However, later it turned out that the machine is still unstable, and still unknown whether he can securely attach to the comet.

Follow the news will arrive in the afternoon, Moscow time, on Thursday, November 13, 2014, when it established a full-fledged relationship with "Rosetta". The fact that the orbiter was in range of radio waves throughout the time of descent of the lander, but when he found himself already on the surface, "Rosetta" came from the area of "visibility". Communication will be restored some time later, and by that time, scientists will already know about the further course of his mission.

Analysis of existing data and allows us to consider another scenario: "Phil" could bounce off the surface of the comet after the first landing, hover in space for some time, and then make another landing. Contact with the comet could be and more. In this case, leaders maintain mission, between the first and second planting could take about two hours, and between the second and third - no more than ten minutes.

Even if the further course of the mission will not match the plans of ESA, nice to know that "Rosetta" and "Phil" already managed to make several significant discoveries during his career. The most interesting of them recently was "song" of the comet Churyumov-Gerasimenko.

This image "Fila" passed during the seven-hour descent (photo ESA / Rosetta / Philae / CIVA).

One of the five tools, "Rosetta", Rosetta Plasma Consortium, designed to study the interaction of the nucleus of the comet with the solar wind and other space phenomena discovered a mysterious signal in the frequency range 40-50 millihertz.

Apparently, scientists have counted, some interaction caused a weak magnetic field of the comet fluctuate. Mission managers decided that the oscillations can be ionization of neutral particles of the tail of the comet, which occurs in collisions of high-energy particles from the interplanetary space. A particle as comet tail are electrically charged, the comet plasma (ionized gas) is reacted with the comet's magnetic field, whereby oscillations occur.

However, on this point it is too early to draw conclusions. ESA scientists still hope that the mission will not suffer due to the fault of the harpoon, and they manage to solve the mystery of "songs" of the comet and its many other mysteries.
