Rosetta continues into its full science phase
Paris (ESA) Nov 20, 2014
With the Philae lander's mission complete, Rosetta will now continue its own extraordinary exploration, orbiting Comet 67P/Churymov-Gerasimenko during the coming year as the enigmatic body arcs ever closer to our Sun. Last week, ESA's Rosetta spacecraft delivered its Philae lander to the surface of the comet for a dramatic touchdown. The lander's planned mission ended after about 64 hours when its batteries ran out, but not before it delivered a full set of results that are now being analysed by s ... read more
