The Philae landing vehicle touched down on Comet 67P/Churyumov–Gerasimenko on Nov. 12, 2014, more than 10 years after departing Earth. Philae and its spacecraft, Rosetta, are named after the obelisk and the stone that were used to decipher Egyptian hieroglyphics. They are operated by the European Space Agency. The landing is the first time humans have landed a spacecraft on a comet. It is expected to supply important scientific data about what comets are made of, and whether they contributed to the formation of life on earth.
