- HP³ experiment is now in a stable position approximately 1.5 metres away from the lander
- Heat flow from the interior of Mars will be investigated
- Operational planning for the DLR instrument is currently underway
COLOGNE (DLR PR) — It stands vertically on flat ground, ready for its historic mission. At 19:18 CET on 12 February 2019, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Heat Flow and Physical Properties Package (HP³) or ‘Mole’ was deployed on the Martian surface using the NASA InSight mission’s robotic arm. In the coming weeks, the remote controlled penetrometer is expected to make space history by becoming the first probe to reach a depth of up to five metres in the Martian subsurface. Its goal is to measure the temperature and thermal conductivity of the subsurface and thus determine the heat flow from the interior of Mars. The heat flow gives researchers indications about the thermal activity of the Red Planet. This can provide insights into the evolution of the Martian interior, whether it still has a hot liquid core, and what makes Earth so special in comparison.
