NASA Rover Detects Electric Sparks in Mars Dust Devils, Storms
Perseverance confirmed a long-suspected phenomenon in which electrical discharges and their associated shock waves can be born within Red Planet mini-twisters. NASA’s Perseverance Mars rover has recorded the sounds of electrical discharges —sparks — and mini-sonic booms in dust devils on Mars. Long theorized, the phenomenon has now been confirmed through audio and electromagnetic recordings captured by the rover’s SuperCam…

Controlled Propulsion for Gentle Landings
A valve designed for NASA rover landings enables effective stage separations for commercial spaceflight The controlled descent of the Mars Curiosity rover included the use of propulsion rockets pointing to the surface to allow a gentle landing. The engine, shown firing in this illustration of Perseverance and the sky crane landing system relied on a pyrovalve that released the rocket…
