This video of the Perseverance rover's gDRT (Gaseous Dust Removal Tool) in action was taken during a test in a vacuum chamber at NASA's Jet Propulsion Laboratory in Southern California in August 2020.
The tool fires 12-pounds-per-square-inch (about 83-kilopascal) puffs of nitrogen at the tailings and dust that cover a rock after it has been abraded by the rover. Five puffs are required per abrasion – one to vent the tanks and four to clear the abrasion.
JPL, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.
