For the first time since Philae fell in silent in the last November, Rosetta is trying to make contact with it.
Philae fell sleep two days after reaching the comet 67P, the cause of this was that Philae ended in a cliff or boulder wall that don't aloud Philae to take as solar energy as it will be needed. But this issue will probably get solved when 67P get nearer to the sun so more sunlight will reach it and because of that more solar energy will receive Philae. Due to this lack of energy Philae turn off all its system except one that prevent that the electrical circuits of Philae get freeze, but Philae is programmed to turn on its system as it receive more solar energy, starting with the system that aloud us to communicate with Philae.
As I said before the ESA is now trying to contact Philae, they are sending to it some orders to get active if it have enough energy, but by this moment the ESA expect that Philae will be receiving data but it will not have enough energy to answer the message. However Rosetta will keep trying to make contact until the 20 of March, and by that day Philae don't have make any contact, Rostta will stop
and will keep trying it in March.
