Tutto quello che volete sapere sulla missione Rosetta 12.11.142014-11-23:03:47
The European Space Agency (ESA) completed one of the biggest space feats in years on Wednesday when it landed a robot on a comet speeding between Jupiter and Mars at nearly 40,000 mph.
The Rosetta spacecraft dropped the refrigerator-sized Philae lander onto comet 67P/Churyumov-Gerasimenko, which is made up of plunging cliffs and rocky terrain.
It's the first time mankind has ever attached a robot to a comet. The chance of success was just 70 percent.
