NASA’s Perseverance Rover Captures 200-Foot-Wide Dust Devil Tearing Across Mars

NASAs Perseverance rover caught this Martian dust devil moving east to west at a clip of about 12 mph (19 kph) along “Thorofare Ridge” on August 30. Using data from the images, mission scientists figured out that this particular dust devil was about 2.5 miles (4 kilometers) away, at a location nicknamed “Thorofare Ridge,” and moving east to west at about 12 miles per hour (19 kph).” We dont see the top of the dust devil, however the shadow it tosses gives us a good indicator of its height,” said Mark Lemmon, a planetary scientist at the Space Science Institute in Boulder, Colorado, and a member of the Perseverance science team.

Dust devils, which take place on Earth as well, form when increasing cells of warm air mix with coming down columns of cooler air.

The six-wheeled geologist identified the tornado as part of an atmospheric expedition of Jezero Crater.
The lower portion of a Martian dust devil was captured moving along the western rim of Mars Jezero Crater by NASAs Perseverance rover on August 30, 2023, the 899th Martian day, or sol, of the objective. The video, which was accelerated 20 times, is composed of 21 frames taken 4 seconds apart by one of the rovers Navcams.
Much weaker and generally smaller sized than Earths twisters, dust devils are among the systems that rearrange and move dust around Mars. Researchers study them to much better understand the Martian atmosphere and improve their weather designs.

Using information from the images, mission scientists figured out that this specific dust devil had to do with 2.5 miles (4 kilometers) away, at a place nicknamed “Thorofare Ridge,” and moving east to west at about 12 miles per hour (19 kph). They calculated its width to be about 200 feet (60 meters). And while just the bottom 387 feet (118 meters) of the swirling vortex show up in the camera frame, the researchers might likewise approximate its full height.
” We do not see the top of the dust devil, but the shadow it tosses offers us a good indication of its height,” said Mark Lemmon, a planetary scientist at the Space Science Institute in Boulder, Colorado, and a member of the Perseverance science group. “Most are vertical columns. If this dust devil were set up that method, its shadow would indicate it is about 1.2 miles (2 kilometers) in height.”

Dust devils, which happen on Earth as well, kind when rising cells of warm air mix with descending columns of cooler air. Perseverance and its fellow NASA Mars rover Curiosity routinely monitor in all instructions for them, taking images in black-and-white to decrease the amount of data sent out to Earth.
More About the Mission
A main goal for Perseverances objective on Mars is astrobiology, consisting of the search for signs of ancient microbial life. The rover will define the worlds geology and previous environment, lead the way for human exploration of the Red Planet, and be the very first objective to collect and cache Martian rock and regolith (damaged rock and dust).
In subsequent NASA missions, working with the European Space Agency (ESA), spacecraft would be sent to the Red Planet to gather these sealed samples from the surface area and return them to Earth for extensive analysis.
The Mars 2020 Perseverance objective is part of NASAs Moon to Mars exploration method, which includes Artemis objectives to the Moon that will assist get ready for human expedition of Mars.
Management and operation of the Perseverance rover fall under JPL, which is supervised by the California Institute of Technology (Caltech) in Pasadena, California, on NASAs behalf.
