Philae Lander Runs Out Of Battery And Enters Deep Sleep | IFLScience.

“It’s been a tense week for space exploration, to say the least. But after a nail biting few days that kept millions around the world on the edge of their seats, with fingers and toes tightly crossed, the ESA has announced that the Philae lander has gone to sleep.

The drama began to unfold shortly after cheers were exchanged as Philae made its momentous arrival onto comet 67P/Churyumov-Gerasimenko on Wednesday. The probe’s anchoring harpoons failed to deploy as it made contact with the surface, and because the gravity on the comet is very weak, Philae rebounded. It took two hours for the robot to finally settle, but unfortunately it ended up stuck along the edge of a crater which blocked the sun’s rays from reaching its solar panels.”
