NASA’s Mars InSight lander ends mission after losing power

The Red Planet’s harsh dust has claimed another spacecraft.

NASA announced Wednesday (Dec. 21) that its InSight landerdesigned to understand the geologic life story of Mars, has completed its mission on the Red Planet. The spacecraft relied on solar power, and after four years on Mars, its sunlight-collecting panels have built up too much dust to generate enough power to run the lander. For months now, the InSight team have been expecting the lander to fall silent. Now, the robot has missed two calls home; scientists last heard from the robot on Dec. 15. NASA will keep listening, but doesn’t expect to hear anything more from the lander.
