Powerful landslides may rumble down Martian slopes at up to 450 mph (725 km/h), sped along by slippery ice, a new study suggests.
Researchers Fabio Vittorio De Blasio and Giovanni Battista Crosta, both of the University of Milano-Bicocca in Italy, modeled the dynamics of landslides on Mars, especially those inside Valles Marineris, the gigantic canyon system near the Red Planet's equator.
The duo found that ice — at the landslides' bases and/or spread widely throughout the Martian soil — is likely a key player in these dramatic flows of Red Planet rock and dirt.
