“Baby” dunes on Mars are big NASA/JPL/Univ. of Arizona

Baby dunes on Mars are pretty big compared to those on Earth. In this 885×512 m (0.55×0.32 mi) frame, there are four dunes of roughly the same size, all of which are about as small as dunes can get on Mars. They’re ~180 m (590 ft) across, several times bigger than similar “elementary” dunes on Earth.
