NASA’s perseverance rover spots dust-filled Martian whirlwind on Mars
NASA's Perseverance rover has spotted a dust-filled whirlwind on Mars. Dust devils, which occur on Earth as well, form when rising cells of warm air mix with descending columns of cooler air. The Martian versions can grow to be much larger than those found on Earth. The lower portion of a Martian dust devil was captured moving along the western rim of Mars' Jezero Crater by NASA's Perseverance rover on August 30, the 899th Martian day, or sol, of the mission, according to team officials.
