Abstract

In the images of nucleus of comet 67P Churyumov—Gerasimenko consolidated material and fine-grained regolith formed due to its weathering are observed. Within the consolidated material the fractures, layer-like forms, knobs of different sizes, pinnacles and crater-like depressions are seen. Surface of the regolith is relatively smooth, but in some places features looking as eolian dunes are seen. By a set of instruments of orbital spacecraft and lander on the nucleus surface and in coma the mineral composition of the nucleus material was determined, a number of organic compounds were identified and deuterium/hydrogen ratio was measured. The latter one turned to be very different from that of terrestrial oceans.
