Eroded gullies on the flanks of Martian craters may have been formed by snowmelt as recently as a few hundred thousand years ago and in sites once occupied by glaciers. Similar conditions can be found in Antarctica's McMurdo Dry Valleys. Rather than being a dead planet, the new data are consistent with dynamic climate changes on Mars.
