Images from Comet 67P

The Philae landing probe captured this image of comet 67P/Churyumov–Gerasimenko as it descended on the comet. The landing probe was part of the Rosetta spacecraft sent by the European Space Agency with the goal of making the first controlled landing on a comet.

An image taken from a distance of about five miles from the surface of the comet 67P. The Philae probe's seven-hour descent on Nov. 11 was viewed by European Space Agency engineers as the most difficult part of the ten-year mission.

Narrow-angle images were used to try to identify the final touchdown point of Rosetta's lander Philae. It is thought that Philae bounced twice before settling on the surface of the comet.
