It has been reported that the European Space Agency is planning to restart Rosetta spacecraft in January after it has spent nearly a three-year-long time in hibernation. This spacecraft has been designed to make close moves with Comet 67P.

Astronomers suspect that if everything will go smooth, the spacecraft is expected to reach its destination in August. It has been reported that the spacecraft will set up its spider like landing on the surface of the comet in November, also called as Philae.

This mission is declared as the first one to make soft landing on the comet. The main feature of the Philae is that a drill has mounted on its surface that can penetrate deep about 20 cm on any surface. This will help the spacecraft to pick up the samples and analyze them right on sight and will ultimately allow the Lander to learn more about surface of the comet.

Astronomers said that the major challenge for them is to keep the Philae affix on the surface of the comet on an extremely low gravity atmosphere. According to the ESA, at the time of landing two self adjusting gears will anchor it to the surface of the comet that will make the spacecraft stay upright.

By this way, the spacecraft will drill secure on the comet's surface in the low gravity environment.
