This image is from the Dawn spacecraft in June 2018, prior to it running out of fuel and ending the mission. The view is the southeastern wall of Occator crater on the dwarf planet Ceres showing “blocks” or boulders sliding down the side of the crater.
Keep in mind the slide must be very slow; the surface gravity is only 0.28 m/s2 compared to 9.8 m/s2 here on Earth. That’s something like 35 times slower.
