NASA’s InSight Mars Lander clears some dust from Solar Panel

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The team behind NASA’s InSight Mars lander has come up with an innovative way to boost the spacecraft’s energy at a time when its power levels have been falling. The lander’s robotic arm trickled sand near one solar panel, helping the wind to carry off some of the panel’s dust. The result was a gain of about 30 watt-hours of energy per sol, or Martian day.

Mars is approaching aphelion, its farthest point from the Sun. That means less sunlight reaches the spacecraft’s dust-covered solar panels, reducing their energy output.

To clean a bit of dust from one of its solar panels, NASA’s InSight lander trickled sand above the panel. The wind-borne sand grains then picked up some dust on the panel, enabling the lander to gain about 30 watt-hours of energy per sol on May 22nd, 2021, the 884th Martian day of the mission.
