According to foreign media CNET, at the end of 2018,NASA's Mars Reconnaissance Orbiter (MRO) has seen traces of "dust devils" on Mars. It looks like some giant monsters have clawed across the surface of Mars.A surprising set of images taken by the Mars Reconnaissance Orbiter show dark "dust devil" traces in contrast to bright sand dunes.
The dust is flying on Mars, which is the first choice of "dust devil". These local cyclones can reach very high heights. NASA discovered a 12 mile (20 kilometer) Cyclone in 2012. They can also leave considerable marks on the landscape, as seen in the MRO view.
One picture shows a close-up of the dark "footprints," while the second offers a broader view. The "footprints" were found at the Galle crater, an area known for its "dust devil" activities. The Galer crater is nicknamed the "smiling face" crater, because its interior structure resembles a classic smiling face.
MRO has been in orbit around mars since 2006, and its HiRise( high-resolution imaging science experiment) camera takes some of the most spectacular images of the red planet. HiRise team describes these trajectories as having
"Dust devil" traces back to the end of 2018, and on Tuesday served as HiRISE HiPodOf the day. The MRO HiRISE camera sent back a large number of images, which made the hipod archive a valuable resource to highlight Mars, otherwise it might be ignored.
Studying the dust devil on Mars can tell scientists about the patterns of Martian winds and how sand dunes are formed.
