Europe's tiny robot lab Philae, hurtling through space on the back of a comet, awoke overnight and sent home its first message in nearly seven months.

What had happened?
Many moons ago, a small space probe named Philae skipped across the surface of Comet 67P/Churyumov-Gerasimenko when the lander's harpoon-like anchoring mechanism failed. It came to rest in a shady spot and, without enough sunlight to keep it powered, it fell asleep after about 60 hours of operation.

What is the mission about?
Philae 

The mission seeks to unlock the long-held secrets of comets , primordial clusters of ice and dust that scientists believe may reveal how the Solar System was formed. 

Philae, equipped with 10 instruments, may now get a grandstand view of the gas, dust and icy crystals that blast from the comet as it gets ever closer to the Sun.
