FRANCE-SPACE-EUROPE-ASTRONOMY-COMET

Scientists work in the scientific mission observation centre of the French space agency Centre National d'Etudes Spatiales (CNES) in Toulouse, southern France, on November 12, 2014, as they wait for the European Space Agency's (ESA) robot craft Philae to land on the Churyumov-Gerasimenko comet after being launched from the space probe Rosetta, following a ten year journey. Europe's Rosetta spacecraft made contact with its robot craft Philae soon after the lander embarked on November 12 on a solo, seven-hour descent to a comet, ground controllers said. Astrophysicists hope Philae will unlock knowledge about the origins of the Solar System and even life on Earth, which some believe may have started with comets "seeding" the planet with life-giving carbon molecules and water.
