It was a months fears: Philae, the first machine built by people, who landed on a Comet, will sign up again? Now, it seems certain: No. The DLR has given up hope and declared the final resting place for the ESA Lander Tan.“The chances that Philae once again makes contact with our team in the lander of the DLR control center, go to zero, and we send any commands also – it would be very surprising if we would receive a signal now”, says Philae project leader Dr. Stephan Ulamec of the German Centre for aviation and Astronautics (DLR). That sounds hard. Had the ESA’s land robot during its mission to enjoy those responsible and conquered the hearts of the media and its users.
Philae DLR Adopted First Comet Lander started journey to the Comet Tan in 2004
The small robot started in 2004 with the spacecraft Rosetta to the comet 67 Churyumov Gerassimenko on March 2. More than ten years the journey of the little robot 1x1x1m lasted until he reached his goal. Located between the paths of Mars and Jupiter he put on 510 million kilometers from the Earth on 12 November 2014 on the cute little also with its 4 km diameter Comet Tan.
However didn’t go as planned: the Harpoon system, which should be stop him on landing, failed his duty, Philae instead hopped about the Comet and finally was located at a site, which no one had expected by the project team. The people on the Earth supplied details of the distant Comet.
Researchers need to evaluate many years of Philaes to data
“It was a unique mission with Philae, it was not only the first time that you ever put on with a lander on a comet’s surface. We have fascinating data, with which we can work for many years”, says Prof. Pascale honorary friend, Board Chairman of the DLR and participating scientist on the mission. “Rosetta and Philae have shown what fascinating manner the space expand the horizon of human and the public can take part in our research.”
Newspapers from Africa to South America, from the United States to Asia and Australia brought the message of the first landing of Comet, in spokesman confirmed all the languages in the newscasts, that Philae had indeed accomplished his goal. We of Ingenieur.de. Philae itself provided for the imaging of the texts: the mini laboratory radioed views into space, images of the surface of the Comet Tan shortly after his landing in the direction of Earth.
Philae was standing in the shade because the power went out
But then weakened Philae, several times. Too little Sun reached him, to recharge the batteries. The contact to the Earth ripped off several times.
In June 2015, the probe reported after months of radio silence for the third time by the Comet Tan. The batteries of the robot were again sufficiently warmed up, to save energy. For conducting scientific experiments was not enough but still. But 185 data packets could be sent.
On the 9th July 2015, Philae sent information for the last time. The engineers of the project consider it possible that the reason for the irregular contacts, and the subsequent silence could be short circuits of the transmitters. “We have time and again different commands sent to the contact with him to stabilize and measured with instruments, but this has unfortunately not been possible,” according to the DLR control center.
