Astronomy Science ~ Officials of the European Space Agency (ESA) the latest news about Philae, which is in the comet 67P / Churyumov-Gerasimenko on Wednesday night.

The space agency said Philae did not land on a point that had been planned. Robot weighs 100 kg it had bounced twice and has shifted a distance of 1 Km from the target point landing. Philae bouncing with a height of 1 Km and the second bounce is lower, 20 meters, and then Philae stop.

"If you look at the picture that we have today, it looks like Philae were facing the stone that very irregular," said Paolo Ferri, director of Philae landing mission. Regarding the final landing point Philae, scientists have not been able to ascertain whether the Philae to land near the hole or cliffs. Ferri grateful Philae radio communication is not interrupted.

Due to the angle detail, ESA only confirm Philae stops very close to the cliffs or caves, or maybe close to the crater.

"There is some speculation about it, that Philae is in a hole, but honestly, we do not know, because we have not seen all the pictures," said Ferri.

Unfortunately, ESA added, one of the three leg was pierced Philae to the surface of a comet, one leg sticking up. This condition could hinder the movement of the robot which under normal conditions move with three legs.

"Today, I feel (Philae) as my feet do not touch the ground," added Ferri. Regarding the reflection that occurs at Philae, scientists describe the surface of the comet 67P more like a 'trampoline' than rock structure.

Because the comet's surface texture looks soft and powdery. This is the one that is expected to lead to indirect Philae solid in landing. Stefan Ulamec, Philae landing manager, said in the emergency position, Philae saved by moving the landing gear. This step makes Philae 'jump' from the surface so that it can in an upright position at this time and access to sunlight better.

Unfortunately, another challenge looms. The robot power is limited. ESA said Philae still leaves 20-30 hours power After that, Philae should get power by switching to a secondary battery obtained from solar panels on the body.
