Landslides inside a crater 🔴 In Tagus Valles, the ancient cratered southern highlands of Mars, the faint traces of a wet past are seen in the form of channels, fluidised debris around craters and blocks of eroded sediments. Volcanic activity may have deposited the fine dusting of dark material visible in the fourth image. In one of the deepest craters in the region, numerous landslides have occurred within this crater, leaving grooves in the crater wall as material slumped to the floor below. 📸 @europeanspaceagency/ @germanaerospacecenter/ @fu_berlin; @creativecommons CC BY-SA 3.0 IGO 📸 @NASA/MGS/MOLA Science Team #Mars #RedPlanet #MarsExpress #CreativeCommons
