Martian Polar Crater Ice Shifts with Seasonal Frost
New observations show ice inside a crater at Mars's poles moving and changing shape in step with the planet's seasonal frost cycle. As temperatures swing through the Martian year, frost deposits and sublimates, reshaping the ice on the crater floor. The findings give scientists a clearer picture of how volatiles behave on Mars and what conditions future missions may face.
Why now: Fresh coverage of new Mars observations is drawing attention from space and climate enthusiasts.
