We have another Martian oddity on our hands.
In this late 2013 image of the red planet, a field of dunes appear in V-shaped formation. Located on a large crater in an old Martian valley, the dunes number in the dozens.
“For dune fields, the spacing of individual dunes is a function of sand supply, wind speed, and topography,” according to NASA.
The formations have been likened to migratory bird formations and even a popular sci-fi show.
