Why 67P is a funny shape

Posted in MiARD

A number of scientists who worked on the MiARD project have subsequently contributed to a recent paper in the journal Nature that seeks to explain how comet 67P/Churyumov-Gerasimenko got its current shape. See Bilobate comet morphology and internal structure controlled by shear deformation  

A summary in lay person’s language has been provided by ESA.

MiARD project completed

Posted in MiARD

The MiARD project has formally finished its work  (as of the end of August 2018), although project members are still working on several publications resulting from the project. The formal review of the project’s work by the European Commission will take place on October 16th, 2018. Datasets and publications from the project be seen here.

Comet 67P formed in impact?

Posted in Comet 67P, Modelling

The unusual shape of comet 67P/Churyumov-Gerasimenko, as recorded by the Rosetta mission, has led to much speculation about its origins. A simulation published in March 2018 in Nature Astronomy suggests that the comet could have formed when two comets collided, and furthermore that such a collision even at quite high speeds would have left the constituent parts largely unaltered (no large rise in temperatures or pressures). This is important because it means that whenever Churyumov-Gerasimenko actually took its current shape, we can still draw conclusions about primordial material from the origins of the solar system using Rosetta results.
