Rosetta’s lander Philae, which made a historic touchdown on comet 67P/Churyumov-Gerasimenko earlier this week, has run out of battery power, the European Space Agency (ESA) said on Saturday.

In a blog post, ESA said that the lander is now in “idle mode” and it is unlikely that communication will be reestablished in the near future. Contact with the spacecraft was lost at 6:36pm ET on Nov. 14.

Philae was expected to deplete its battery power this weekend, but the event happened a little earlier than planned. The spacecraft had a bouncy landing on the comet on Nov. 12, which placed it in a spot that offered less sunlight to charge its solar panels.

Scientists were in a frenzy to deploy the lander’s instruments before the power went out. According to ESA, Philae transmitted all the data it collected back to Earth before it went to sleep.

"This machine performed magnificently under tough conditions, and we can be fully proud of the incredible scientific success Philae has delivered,” Stephan Ulamec, landing manager for the German Aerospace Agency (DLR), said in a statement.

Before the power went out, the lander sent back some incredible photos—the first ones ever taken on the surface of a comet. Scientists hope that the data sent from the lander can offer some insight on the composition of comets and possibly on the formation of our solar system.

The lander could wake up again if enough sunlight reaches its solar panels.

The Rosetta mission includes a lander and an orbiter. The orbiter will continue to fly over the comet and listen for possible signals coming from the lander.
