ESA Attempts To Land Probe On Comet [Getty Images]

DARMSTADT, GERMANY - NOVEMBER 12: (EDITORIAL USE ONLY) In this November 10, 2014 handout photo illustration provided by the European Space Agency (ESA) the Rosetta probe (L) and Philae lander are pictured above the 67P/Churyumov-Gerasimenko comet. ESA will attempt to land the Philae lander onto the comet in the afternoon (GMT) of November 12 which, if successful, will be the first time ever that a man-made craft has landed onto a comet. The Philae lander is a mini laboratory that will harpoon itself to the surface, though a problem with a gas thruster detected November 11 is making the outcome of the landing uncertain.
