Ah, this is great news. The European Space Agency‘s lander on (deep breath) Comet 67/P Churyumov-Gerasimenko has woken from its sleep. It landed on the surface of the comet last November, launched from the space probe Rosetta, but bounced on landing after its anchoring mechanisms failed, and ended up in a deeply-shaded ditch. As its solar panels didn’t then receive enough sunlight to generate power, it went into hibernation after sending back a small amount of information. However, the comet has since moved closer to the sun and is receiving more sunlight, and as the scientists had hoped, Philae has started working again and is able to send messages back to earth, via Rosetta, which is still orbiting the comet.
Yay! So exciting! Lots of fantastic science experiments to come. Drilling! Analysing! Hurrah!
