A new paper detailing the first 216 days of Perseverance’s mission in Jezero Crater reports how the newest rover on Mars appears to be located in a “dust storm track” that runs north to south across the planet. Jezero Crater has particularly high levels of dust and wind activity.
Dust devils are generally used as a trope in media when the writers want to know that an area is deserted. They signify the desolation and isolation that those places represent. Almost none of the settings of those stories are close to the isolation of Perseverance, the Mars rover that landed on the planet earlier this year. Fittingly, the number of dust devils Perseverance has detected is also extremely high – over 300 in its first three months on the planet.
We live in a time when our spacecraft orbiting Mars at an altitude of about 300 km. can snap photos of a dust devil and transmit them back to us so we can share them on the internet. Not only that, but we have rovers wandering around on the surface taking pictures of the dust storms, too. Big deal, you say? So what, you say?
