"Philae" was monitored and operated from DLR's Lander Control Center in Cologne, Germany. "Philae" mission was to land successfully on the surface of a comet, attach itself, and transmit data about the comet's composition. The "Rosetta" spacecraft and "Philae" lander were launched on an Ariane 5G+ rocket from French Guiana on 2 March 2004, 07:17 UTC, and travelled for 3,907 days (10.7 years) to Churyumov–Gerasimenko. Unlike the "Deep Impact" probe, which by design struck comet Tempel 1's nucleus on 4
