After more than four years on the Red Planet, NASA mission managers have concluded that the solar-powered InSight lander has run out of energy. NASA’s InSight mission has ended after collecting unique science on Mars for more than four years. Mission controllers at NASA’s Jet Propulsion Labora
This is one of the last images ever taken by NASA’s InSight Mars lander. Captured on December 11, 2022, the 1,436th Martian day, or sol, of the mission, it shows InSight’s seismometer on the Red Planet’s surface. Credit: NASA/JPL-Caltech
The seismometer was the last science instrument that remained powered on as dust accumulating on the lander’s solar panels gradually reduced its energy, a process that began before“InSight has more than lived up to its name. As a scientist who’s spent a career studying Mars, it’s been a thrill to see what the lander has achieved, thanks to an entire team of people across the globe who helped make this mission a success,” said Laurie Leshin, director of JPL, which manages the mission.
All Mars missions face challenges, and InSight was no different. The lander featured a self-hammering spike – nicknamed “the mole” – that was intended to dig 16 feet down, trailing a sensor-laden tether that would measure heat within the planet, enabling scientists to calculate how much energy was left over from Mars’ formation.
in inventive ways. Primarily intended to set science instruments on the Martian surface, the arm and its small scoop also helped remove dust from InSight’s solar panels as power began to diminish. Counterintuitively, the mission determined they could sprinkle dirt from the scoop onto the panels during windy days, allowing the falling granules to gently sweep dust off the panels.
