After four years on the Red Planet, InSight is signing off. 🤖 Our InSight mission, which has been collecting unique scientific data on Mars, has come to an end. After two consecutive attempts, the mission team at nasajpl was unable to contact the lander, a sign that the spacecraft’s solar-powered batteries have run out. InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) set out to study the deep interior of Mars in 2018 and achieved its primary science goals in its first Mars year (nearly two Earth years). Since arriving on the Red Planet, InSight has left a legacy worthy of its name, gathering a rich bounty of scientific data. The mission made scientific discoveries on a seismic scale, its instruments revealing details about Mars’ crust, mantle, and core, helping scientists better understand how all rocky worlds form, including Earth and its Moon. Over its four-year stint at Elysium Planitia, a flat smooth plain that served as its l...
