ESA's Rosetta probe captured images that could prove that there are landslides on the surface of comet 67P. The changing weather, geologic process and mechanical effects of spinning are some of the reasons cited that's causing erosion.
ESA' Rosetta comet hunter mission officially ended last Sept. 30. The agency recently released the final data collected by the spacecraft including photos of the comet during Rosetta's descent.
ESA's Rosetta comet chaser will be switched off and will crash to its death on Sept. 30.
