Several sites of cliff collapse on comet 67P/Churyumov-Gerasimenko were identified during Rosetta's mission. The yellow arrows mark the fractures where the detachment occurred. The collapsed sections are about 50 feet (15 meters) long for the left-hand section, and 30 feet (9 meters) for the right-hand section. Additional images taken from greater distances suggest the collapse occurred between May and December 2015.
<p>The images were taken by Rosetta's OSIRIS camera on Dec. 2, 2014 (left), and March 12, 2016 (right), with resolutions of 1.6 feet (0.5 meters) per pixel and 1 foot (0.3 meters) per pixel, respectively.
</p><p>Rosetta is a European Space Agency mission with contributions from its member states and NASA. Rosetta's Philae lander is provided by a consortium led by the German Aerospace Center, Cologne; Max Planck Institute for Solar System Research, Gottingen; French National Space Agency, Paris; and the Italian Space Agency, Rome. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, Pasadena, manages the U.S. participation in the Rosetta mission for NASA's Science Mission Directorate in Washington.
