Abstract

The InSight Mars mission landed in Homestead hollow in the Elysium Planitia region of Mars at 4.50°N, 135.62°E on Nov. 3rd, 2018. The Heat Flow and Physical Properties Package (HP3) is part of the InSight payload and is designed to emplace sensors into the martian regolith to measure regolith thermal conductivity and the geothermal gradient in the 0-5 m depth range [2]. Due to unexpected soil properties, the lander’s robotic arm needed to assist in probe emplacement. We estimate the mole’s back-cap to be 2-3 cm below the surface during the measurement, and since the mole is 40 cm long and inclined 30° with respect to vertical, he mole tip is likely at 37 cm depth.
