Orbital observations unveil the presence of an enormous mantle plume pushing the surface of Mars upward and driving intense volcanic and seismic activity. On Earth, shifting tectonic plates reshuffle the planet’s surface and make for a dynamic interior, so the absence of such processes on Mars led many to think of it as a dead planet, where not much happened in the past 3 billion years.

In the current issue of Nature Astronomy, scientists from the University of Arizona challenge current views of Martian geodynamic evolution with a report on the discover...

NASA’s Mars mission InSight probes the geology of the Elysium Planitia, finding alternate layers of basalt and sediments. An international team of scientists compares on-the-ground data with data from models, which helps to understand, e.g., the surface’s load-bearing capacity and trafficability.

Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet’s surface. These findings were gained in the framework of NASA’s InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners, including the University of Cologne, collaborate...
