Mission control receives signal confirming first successful landing on the surface of a comet 317 million miles away
Comet landing
A historic attempt to land a spacecraft on a comet was set in motion Wednesday by scientists at the European Space Agency, despite a last-minute problem with the landing system. It was the climax of a decade-long mission to study a 2.5 mile wide lump of dust and ice known as 67P/Churyumov-Gerasimenko. It marked the end of a 4 billion-mile journey that Rosetta and its sidekick craft, Philae, made together to reach the comet.
