Mars Twisters: Curiosity Rover Spots Red Planet Dust Devils

Mars Twisters: Curiosity Rover Spots Red Planet Dust Devils

It’s been just revealed that NASA’s Mars Curiosity rover managed to spot a dust devil swirling through the Red Planet’s landscape.

Curiosity managed to photograph the dust devil on August 9, and it captured a spectral feature that dances along the border between dark and light slopes which are insider the planet’s 96-mile wide Gale Crater.

The Curiosity team members said that it’s not a surprise the fact that these dry whirlwinds which we also get on Earth are cropping up inside the crater.

“It’s almost summer in Gale Crater, which puts us in a period of strong surface heating that lasts from early spring through mid-summer,” Claire Newman, an atmospheric scientist at the Arizona-based company Aeolis Research, wrote in a mission update last week.

“Stronger surface heating tends to produce stronger convection and convective vortices, which consist of fast winds whipping around low-pressure cores,” Newman wrote.

She continued and explained that “If those vortices are strong enough, they can raise dust from the surface and become visible as ‘dust devils’ that we can image with our cameras.”

The photos have to be processed 

Dust devils are quite faint and this means that Curiosity photos have to be processed before the features are visible. The August 9 whirlwind showed up even in the raw, unprocessed rover imagery. 

It’s also worth noting that the recent activities of Curiosity have included a study of such dust devils and the camera of the rover has been used for this. 

You are probably aware of the fact that the rover has spotted dust devils on Mars before as well and so did NASA’s Opportunity and Spirit rovers as well.
