InSight's Robotic Arm Helps Remove Solar Panel Dust Trickles Sand in the Wind

NASA's InSight lander tried a novel approach to remove dust clinging to one of its solar panels. On May 22, 2021, the 884th Martian day, or sol, of the mission, the lander's robotic arm trickled sand above the panel. As wind carried the sand grains across the panel, they picked up some dust along the way, enabling the lander to gain about 30 watt-hours of energy per sol.
