Since InSight’s landing on Mars late last year, it’s been hard at work studying what lays beneath the surface of the Red Planet. The lander’s mission is to understand Mars’ deep interior, what it’s made of and how the planet moves. To that end, InSight has been studying the area around it, practicing its movements, and scouting the best locations to place instruments. And now, the science is kicking into gear.
To accomplish its mission, InSight needs to place a few instruments on the surface and then monitor them. The lander has two main instruments it has to re-home: the Heat flow and Physical Properties Package (HP3) and the Seismic Experiment for Interior Structure (SEIS). The first will measure temperatures underneath Mars’ surface, while the latter will listen for subtle Mars-quakes. InSight also carries a Rotation and Interior Structure Experiment (RISE), but this will remain riding piggy-back on the lander for the duration of the two-year mission.
