May 2018 will see the launch of the NASA Insight mission, in which a lander will carry out geophysical measurements directly on the surface of Mars to explore the planet’s inner structure and thermal balance. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has contributed to this mission in the form of the HP3 instrument. On 26 November 2018, InSight will touch down north of the equator, on the Elysium Planitia plain. Following a test phase, the experiments will commence after the 2018/19 turn of the year. The duration of the mission is initially set at one Mars year, which corresponds to approximately two Earth years.
For the first time since the astronaut mission Apollo 17 in 1972, heat flow measurements will be carried out on another celestial body using a drilling mechanism. The main aim of the experiment is to be able to determine the thermal state of the interior of Mars using thermal flow measurements taken beneath the surface. Models of Mars’ formation, chemical composition and inner structure can be checked and refined on the basis of this data. The measurements from Mars can also be used to draw conclusions about Earth’s early development.

Just a few weeks from now, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) HP3 Mole will start hammering its way automatically into the subsoil of the Red Planet to measure its inner heat.
On 26 November 2018, NASA's InSight probe is expected to land on Mars' Elysium Planitia plain at a 4.5 degrees north and135.9 degrees east. This video shows a flight over the landing site and surrounding area. It was produced based on a digital terrain model calculated using stereo image data from DLR's High Resolution Stereo Camera (HRSC).
It will be the deepest hole ever hammered into another celestial body using manmade technology. During the NASA InSight mission, the Heat Flow and Physical Properties Package (HP3), the Mole, which was developed and built by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) will penetrate up to five metres deep into the Martian soil to measure the temperature and thermal conductivity of the substrate materials there. This glimpse of the interior of the Red Planet will help us to better understand the formation and evolution of Earth-like bodies.
