The Philae robot falls into the state of

After two days of landing on the surface of a comet, Philae was in a state of "hibernation" due to the exhaustion of energy.

The European Space Agency (ESA) said that because Philae's battery was exhausted and not enough sunlight to maintain energy, it had fallen into an inactive mode. In this state, all devices and systems are off.

Scientists estimate that the comet's lighting time is 7 hours a day. However, the real lighting time is only 1.5 hours and not enough to supply the battery system.

According to CNN, the team attempts to improve the energy state for Philae by passing commands to change the body configuration. The main body of the robot is enhanced and rotated 35 degrees to maximize the ability to receive light for the panels. Conditions can change if the comet moves closer to the Sun and provides the necessary amount of light.

Despite the pause, Philae transmitted data and black and white images to Earth. The ESA expert team said about 80% of the basic goals were achieved.

The European Space Agency's (ESA) exploration robot landed on the comet surface of 67P / Churyumov-Gerasimenko on November 12. This is the first time the world space science has achieved this achievement.
