NASA’s Perseverance mission dropped its first cache of precious rock samples on the sands of Mars, leaving behind a record of material that a future mission could bring back to Earth. It’s a key moment in the search for life on Mars, NASA officials said in a statement on Wednesday (Dec. 21).

NASA announced Wednesday (Dec. 21) that its InSight lander, designed 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.
