Why Mars helicopters like Ingenuity could glow in the dark

Helicopters making dusk flights on Mars may radiance in the dark.A brand-new study suggests that Mars drones, such as the Ingenuity helicopter making regular sorties on the Red Planet, “might cause small electric currents to stream in the Martian environment,” according to NASA.The possible currents are not a risk to the helicopter, if they do undoubtedly develop in the first location, however would develop an intriguing effect for any cameras that are close by.

The research study was released prior to the Perseverance rover and Ingenuity landed on Mars on Feb. 18, 2021; almost a year later, Ingenuity has actually made 18 flights and invested more than 30 minutes up throughout these numerous sorties.Follow Elizabeth Howell on Twitter @howellspace.
