The research module Philae, located on the surface of the comet Churyumov-Gerasimenko, ceased to transmit a signal to Earth. However, the obtained data using the device, the scientists believe, will help to verify the hypothesis of the origin of water on Earth.
“The loss of signal. Links to Philae is no more. All the scientific data from the first session successfully transferred” – quoted by TASS message ESA mission control center.
Shortly before that, European experts have recorded the transfer of all the systems on board the landing module into sleep mode due to a low battery level. Remains of the energy spent on maintenance of the communication channel. By 1:43 CET (3:43 Moscow time) expectedly stopped and the transmission signal.
“You did a great job, Philae, this did not make even a single spacecraft,” – wrote a farewell ESA staff in the official Twitter of the mission.
Researchers at the same time argue that the mission was a success anyway. Firstly, the unit for the first time in history managed to land on a comet. Secondly, some of the information to Earth, he managed to convey. According to the estimates of the European Space Agency, Philae fulfilled 80% of the tasks. In addition, satellite Rosetta will continue its work on data transmission.
Recall that on November 14 in the center of space research CNES announced that the module can will soon stop working due to lack of energy.
In the research program of Philae were planned drilling. According to the original plan, the module was to remove the core, to analyze it and transmit the data to the European Space Agency. After landing in the ESA decided to postpone drilling due to a lack of energy.
However, the news that the device may soon stop working, have forced researchers to make adjustments to the module. “Get back to work! Starts drilling surface P67″, – was reported in Twitter the machine after the news of his impending death. Then, in the ESA reported that Philae successfully conducted drilling operations.
Scientists believe that the collected data will help Philae test the hypothesis occurrence of water on Earth
Head of Chair of astronomy and space geodesy Kazan (Volga Region) Federal University, Professor Ilfan Bikmaev said that the data on the composition of ice comet Churyumov-Gerasimenko, the assembled apparatus Philae, will allow scientists to test the hypothesis appearance of water on the planet Earth.
“There is a hypothesis that in the solar system at an early stage of its formation was a lot of comets. They crashed into the planet, including the Earth and could become a source of water. On some celestial bodies, including Moon traces of deformation from falling comets. The study of ice on the comet Churyumov-Gerasimenko will determine what it consists of, – water or gas, “- said Bikmaev, quoted by TASS.
According to the professor, the study of ice will give scientists new facts allow to confirm or refute this hypothesis. He noted that until now scientists have studied the composition of comets only through telescopes, studying in different rays of the spectrum fragments of comet tails, but this information is very conditional.
The descent module Philae was taken to the comet P67 / Churyumov-Gerasimenko probe Rosetta, which was launched on March 2, 2004. The purpose of the mission is to obtain information about the origin and evolution of the solar system. Rosetta comet reached November 12, 2014. Launching apparatus Philae to the surface of the comet took about seven hours.
