Mars InSight Lander

Mission Ended

Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. First mission to study Mars' deep interior.

Mission Conclusion

The mission ended after gradually losing power due to dust accumulation on its solar panels. NASA declared the mission over on December 21, 2022, after two consecutive failed communication attempts.
