After two and a half years of planned hibernation in deep space, today, at 11 hours, four internal alarms have awakened from their slumber to the Rosetta spacecraft, which is about 810 million miles from Earth.

It's just part of the distance traveled during the decade that has passed since March 2004 in French Guiana began his extraordinary journey aboard an Ariane 5 rocket, toward the comet 67P/Churyumov-Gerasimenko.
The probe will take several hours to stretch and warm enough to be able to communicate with Earth, eagerly awaiting a signal engineers from the European Space Agency (ESA), eager to prove she's still alive.
The spacecraft is finally prepared for the great object of his mission: to explore for the first time a comet, a celestial objects that scientists believe that information about the origin of our solar system is conserved.
