The SEIS experiment on board NASA’s InSight geophysical station recorded 174 seismic events up to the end of September 2019.Weak earthquakes – magnitude less than three to four.Accompanying measurements provide information about the local weather conditions.In the coming weeks, the Mars ‘Mole’ is to be assisted more effectively by pressure from above applied with the robotic arm.

COLOGNE (DLR PR) — Mars is a seismically active planet – quakes occur several times a day. Although they are not particularly strong, they are easily measurable during the quiet evening hours. This is one of many results of the evaluation of measurement data from the NASA InSight lander, which has been operating as a geophysical observatory on the surface of Mars since 2019.

A series of six papers have now been published in the scientific journals Nature Geoscience and Nature Communications. Eight scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have made contributions to these. The papers describe the weather and atmospheric dynamics at the landing site, its geological environment, the structure of the Martian crust and the nature and properties of the planetary surface.
