For years, space companies have turned to analog missions on Earth to organize for robotic and crewed missions to different worlds. Researchers have additionally studied Earth-based phenomena to grasp what pure processes are occurring elsewhere. The newest program to affix the analog catalog is a examine from NASA’s Jet Propulsion Laboratory (JPL) in California that is analyzing dust devils on Earth to find out about their counterpart on Mars.
In a presentation Wednesday (Dec. 7) on the 183rd Assembly of the Acoustical Society of America in Nashville, Louis Urtecho, an undergraduate scholar conducting the analysis by JPL, detailed his crew’s examine of dust devils, or temporary whirlwinds, within the Mojave Desert.
“The abundance of dust devils on Mars might have implications for the lifetimes of many missions. In reality, dust devils have already performed a task in previous missions,” Urtecho stated in a press release. “Opportunity and Spirit rovers’ lives had been prolonged as a result of pleasant dust devils blew dust off their solar panels. However Alternative ultimately succumbed to a worldwide dust storm on Mars, exhibiting the significance of dust loading within the environment.”

Given the restricted sources on Mars, it is troublesome to check Martian dust devils in depth. Luckily, the phenomenon happens ceaselessly in Earth’s deserts.
The JPL crew is analyzing seven years of stress knowledge taken by microbarometers on the Nevada Nuclear Safety Website within the Mojave Desert, looking for the telltale signatures of dust devils: drops in stress within the middle of the vortices that fluctuate like an electrocardiogram (EKG) sign. With a lot info to sift by, the crew has developed an automatic detection algorithm to determine the related knowledge. Ultimately, the crew will modify its evaluation of the dust devils to Martian atmospheric circumstances.
“The hope is that with our dust satan detector we can be taught extra in regards to the formation traits of convective vortices and the way they transfer throughout varied landscapes,” Urtecho stated. “This may enhance the accuracy of Martian climate fashions, which has a direct impression not solely in understanding dust cycles on Mars and the position they’ve performed in its evolution, but additionally the operation of future robotic and presumably crewed missions.”
