Good Morning Philae!

After seven months of hibernation in a dark corner of a lonely comet 67P, Philae has finally woken up! At 2228 CEST, The European Space Agency, received about 85 seconds of communication from the lander that made the comet 67P/ Churyumov/ Gerasimenko its home in November last year.

In the 85 seconds of contact that Philae made via its mothership, Rosetta (read 5 reasons why Rosetta is a Superstar), scientists at the Lander Control Center at the German Aerospace Center received some data packets that show that Philae had probably woken up earlier but failed to contact Earth.

Nevertheless, Philae's battery is now recharged 24 Watts of its 140 Watt Hour capacity and will get better as the comet is approaching the Sun. Philae's revival also means that scientists can now get access to all the data that Philae had recorded before it went into hibernation but could deliver to Earth.

There are exciting days ahead for Philae as life lives his life on a comet and for the ESA who will h…

Rosetta update: Philae's landing site chosen and a 3D model of the Rosetta mission!

Having analysed all the landing site options in depth, the European Space Agency (ESA) has finally made its choice for the landing site for Rosetta's probe, Philae. After shortlisting five probable sites earlier, the ESA had to go back to its longer list of probable landing sites after the sites were found not be be safe for landing Philae
After much deliberation and rethinking,  the ESA is looking at site J as the possible landing place for Philae and will now make its decision final by September 26 after completing trajectory analysis. If our readers recollect, the landing mission of Philae is going to be completely autonomous with no possibility of real time maneuvering after the probe leaves Rosetta. The ESA therefore needs to be absolutely sure that the landing site is perfect for probe, not only to land, but also have sufficient lighting for Philae to be able to charge its batteries and continue his analysis of the comet's surface after landing. Also, site C has been …
