Images successfully captured by NASA’s Curiosity rover show a “dust demon” “cruised” on Mars’ dry surface,media BGR reported. “Dust demons” occur when temperatures are not normal to produce vortexes, much like what happens on Earth. In the latest update to the Curiosity mission blog, we’ve seen a truly incredible set of images showing the actions of Mars’ “dust demons.”
Curiosity, currently at Gale Crater, has been exploring the Martian landscape for years. It periodically captures images of its surroundings and sends them back to Earth. These images help NASA’s Curiosity team plan future trips, but occasionally they reveal something else. In this case, it is a vortex of wind that sweeps across the dusty terrain.
“Now the Gale Crater is almost summer, which places us in a period of intense surface heating, from early spring until midsummer,” NASA’s Curiosity team explained. “Stronger surface heating tends to produce stronger vortex and vortex, which consists of fast winds whipping around the low-pressure core. If these vortexes are strong enough, they can pick up dust from the ground and become visible ‘dust demons’, which we can shoot with a camera. “
