This was the reason that the lander’s batteries quickly ran out of power and it could send back only a small portion of data that had been hoped for.

“Today communication with Philae was stopped”, Andreas Schütz, media spokesman of German space agency DLR, told the AFP on Wednesday.
Writing an extraordinary chapter in space history, the washing machine-sized craft was the first to land on a comet – primeval rubble from the formation of the Solar System. “Tomorrow, the unit on @ESA_Rosetta for communication with me will be switched off forever”.
Philae’s team was satisfied with the mission, though. Image credit: European Space Agency. The comet is now heading away from the sun, which saps the spacecraft of the solar power it needs to continue operations. As a outcome, there is less energy for the spacecraft to keep working.
But, Martin added that the mission of Philae and Rosetta will always be remembered as an incredible success. “In order to continue scientific operations over the next two months and to maximize their return, it became necessary to start reducing the power consumed by the non-essential payload components on board”.
But after more than 12 months without news, it was chose to preserve all remaining energy available to Philae’s orbiting mothership Rosetta, the European Space Agency (ESA) announced in a blog entitled: “Farewell, silent Philae”.
Now confirmed as in a state of “eternal hibernation”, when Philae originally went quiet this wonderful video was produced, telling the ten-year story of the Rosetta mission in just a few adorable minutes. In spite of that, the ESS has been kept on throughout the time and many attempts have been made to regain the contact but eventually they chose to turn if off to save energy for future experiments.
“We found that the comet wasn’t as rich in ice as we thought it would be”, Essam Heggy, a co-investigator for the CONSERT instrument for the Rosetta Mission, says in the video. There is a sense of poetry to Rosetta rejoining its lander on the comet.
Philae, the first robot to land on a comet, has reached the end of its life and is bidding a final farewell to Earth through a series of sad tweets. By the end of July, Comet 67P will be more than 320 million miles from the Sun, which means Rosetta won’t be getting as much power. The Rosetta mission will officially end September 30.
With no solar energy reaching its panels, the spacecraft turned off two days later. It worked for some time.
Its last transmission was July 2015.
Scientists tried to get communication back, but none of the attempts worked.

“It’s time for me to say goodbye”, the three-legged lander “wrote” on Twitter.
