(NASA Mars mission to study its interior)

InSight (for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) was a NASA Discovery Program Mars lander mission to investigate Mars' interior. Among its discoveries, it confirmed that Mars' core is liquid. It was launched in May 2018 and beginning that November, carried out its two-year primary mission. Mission extensions were approved through 2025, but contact was lost in December 2022, likely because of dust collecting on its solar panels: gradual declines in its power suggest this. Since early 2023 the mission is officially retired, though NASA continues to check for any new signal from the probe. There remains a possibility that wind might clear the solar panels and restore power. Instruments:

The goal of HP3 was to burrow to a depth of five meters, but only it reached about a third of a meter depth.
