Cliff Collapses on Rosetta's Comet

March 21, 2017
Several sites of cliff collapse on comet 67P/Churyumov-Gerasimenko were identified during ESA's Rosetta's mission. The yellow arrows mark the fractures where the detachment occurred.

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.

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.

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.
