Space Agency Looks Back on 'Year of Rosetta'

2014 was a momentous year for the European Space Agency. After a decade-long voyage, its Rosetta spacecraft rendezvoused with comet 67P/Churyumov-Gerasimenko, where its Philae lander was deployed to touch down on the comet’s surface. Philae’s mission will continue next year, and its findings could provide clues about the origins of life on Earth.
