7, following a large, regional dust storm that reduced the sunlight reaching its solar panels.

Drained batteries are believed to have caused the end of NASA’s Opportunity rover during an epic series of dust storms that blanketed the Red Planet in 2018.

Even before this recent dust storm, dust had been accumulating on InSight’s solar panels, reducing the lander’s power supply.

Dust storms can affect solar panels in two ways: Dust reduces sunlight filtering through the atmosphere, and it can also accumulate on the panels.

Whether this storm will leave an additional layer of dust on the solar panels remains to be determined.

The current dust storm was first detected by the Mars Color Imager (MARCI) camera aboard NASA’s Mars Reconnaissance Orbiter, which creates daily color maps of the entire planet.

The whirlwinds and gusts of dust storms have helped to clear solar panels over time, as with the Spirit and Opportunity Mars rover missions.

Lockheed Martin Space in Denver built the InSight spacecraft, including its cruise stage and lander, and supports spacecraft operations for the mission.
