HiRISE Mars 4K (NASA): The Things that Blow Away

This part of the observation gives us a view of linear dunes in northwest Argyre Planitia that appear thin as they have followed the direction of the Martian wind. This image was requested for change detection. The movement of the dunes is very slow, but inexorable. You can also see numerous meters-sized boulders throughout the scene. (This image is the center swath of the full observation using the red-green-blue filter.)

This is a non-narrated clip with ambient sound. Image is less than 1 km (under 1 mi) across and the spacecraft altitude was 254 km (158 mi). For full images including scale bars, visit the source link.
