Rosetta ends 12-year space odyssey After chasing a comet across nearly seven billion km of space, the historic Rosetta mission will end when the spacecraft gently crashlands on its surface and shuts down forever Feb 2016: Temperature falls to -180oC, Philae no longer able to function. Rosetta continues tracking 67P Sep 30, 2016: Mission ends Mar 2004: Rosetta launched June 2011: After four flybys of Earth and Mars, Rosetta is put into hibernation to save energy Jan 2014: Rosetta wakes Earth orbit Rosetta orbit 67P orbit Aug: Comet comes within 186 million km of Sun Jul: Last contact with Philae Jun 2015: Philae sends unexpected message: “Hello Earth! Can you hear me?” Nov 12: Philae becomes first ever spacecraft to land on comet. Probe bounces three times before ending up in deep shade where it not be recharged Aug 6: Rosetta enters orbit of Comet 67P/Churyumov-Gerasimenko and maps it to determine viable landing site for Philae lander Philae lander Rosetta orbiter Philae first touches down Philae’s final resting place: On Sep 2, 2016, Rosetta’s high- resolution camera spots Philae wedged into dark crack Comet landing sites Organic compounds detected in 67P bolster notion that comets delivered chemical building blocks for life to Earth and throughout solar system Rosetta’s planned impact site: In final hours of controlled 14-hour descent, Rosetta will take close-up pictures of comet and collect data on gases closer to surface Source: ESA Picture: ESA/Rosetta/NAVCAM, CC BY-SA IGO 3.0
