As humanity’s robot rovers continue to roll over and scan the surface of MarsOpens in a new tab, we continue to see the Red Planet in unprecedented detail. In a new video released by NASA’s Jet Propulsion Laboratory (JPL), the Curiosity rover shows an up-close look at sand ripples on the Martian surface. They seem surreal when you consider Martian winds blew them into their smooth, familiar pattern.
JPL recently posted the new, incredible view of Mars’ surface to its YouTube channelOpens in a new tab. The research center notes that Curiosity is currently exploring Mount Sharp, a five-mile-tall mountain within the basin of the Gale Crater. That is the 100-mile-wide crater in the northwestern part of the planet home to bizarre rocksOpens in a new tab and beautiful sunsets.
In the video above, JPL shows a panorama view of the Gale Crater, highlighting the wind-swept sands. And that’s among several other geological featuresOpens in a new tab of the sandy surface that make Mars feel more like home. (A reality that could come to fruition this decade if companies like SpaceXOpens in a new tab have their way.)

As the narrator notes, the dark ripples are sands consisting of broken bits of volcanic rock. Martian winds, while low in density—Mars’ atmosphere is super thinOpens in a new tab—are high enough in velocity to play with particles, shaping them like little dunes just like those on Earth. For reference, Martian winds can gust at up to 70 miles per hourOpens in a new tab. Although, again, the atmosphere’s low density means the winds are exceptionally weak.
Curiosity recorded this panorama of images on July 3, 2021, the 3,167th Martian day of its mission. The rover’s now been on the planet for nine years and seems like it could continue on indefinitely. Although NASA does need to maneuver its rovers around the actual sand dune patches. As is the case on Earth, and Tatooine, Martian sand is rough and courseOpens in a new tab and gets everywhere… Seriously though, it could be catastrophic for the mission.
