Philae wakes up
European Space Agency (ESA), reported on Philae’s space vehicle woke up again. The vehicle sent a message as follows: “Hello world! Do you hear me?”
In November 2014 while landing to the surface of Comet 67P, a small accident had occurred and Philae had fallen into a region that does not see the sun. However, she had continued to send messages for 60 hours, until her batteries completely exhausted.
Since that time, Philae was sleeping. When Comet 67P comet cameenough to the sun, Philae succeeded to charge her batteries and re-started to send messages.
More detailed information on the issue has been published on ESA’s blog page: http://blogs.esa.int/rosetta/2015/06/14/rosettas-lander-philae-wakes-up-from-hibernation/
