Landslides and avalanches could be important to keep a comet active for a long time

An article published in the journal “Icarus” describes a research focused on the link between landslides and avalanches with the long-term activity of the comet 67P/Churyumov-Gerasimenko. Jordan K. Steckloff and Nalin H. Samarasinha of the Planetary Science Institute examined data collected by ESA’s Rosetta space probe in the course of its mission to conclude that those phenomena occurring on the surface of the comet, with the resulting waste of mass, are a key to keeping it active in the long term.
