On Dec. 21, 2022, NASA announced that its InSight lander mission on Mars had ended after efforts to regain contact with the spacecraft failed. InSight did not respond to communications beginning on Dec. 18, 2022.
The end of the mission capped an intrepid science mission that lasted just over four years, which was two years beyond the planned prime mission as envisioned by NASA’s Jet Propulsion Laboratory. InSight is an acronym for the mission’s full name: Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport.
