Slope Streaks (IMAGE)
Caption
CaSSIS camera aboard ESA’s ExoMars Trace Gas Orbiter captures dark finger-like slope streaks extending
across Mars' dusty surface in Arabia Terra. New research by Bickel and Valantinas reveals these features
form through dry avalanches triggered by wind and impacts rather than liquid water. These active
geological phenomena may transport millions of tons of dust annually, potentially playing a significant
role in Mars' climate system.
