NASA’s Mars Reconnaissance Orbiter captured images of frozen sand dunes in Mars’ northern hemisphere, revealing unique formations halted by carbon dioxide frost during winter. Unlike Earth’s desert dunes, which shift with wind, these Martian dunes remain stationary until spring thaw releases their icy grip. Scientists study these features to understand whether Mars on…NASA’s Mars Reconnaissance Orbiter captured images of frozen sand dunes in Mars’ northern hemisphere, revealing unique formations halted by carbon dioxide frost during winter.
