Mars may not be the geologically dead world we thought it was, as hints of magma have been discovered underground.
The Red Planet is thought to have been volcanically active in the past, but not for many millions of years. Now, by studying a cluster of more than 20 seismic events on Mars using data from NASA’s InSight lander mission, Simon Stähler at ETH Zurich in Switzerland and his colleagues have uncovered a likely magma deposit near Cerberus Fossae, a region of fissures created by fault lines.
InSight landed on Mars in 2018 with the objective of studying seismic waves that travel across the planet’s surface and from deep within its interior. By investigating the speed and frequency of these waves, we can better understand Mars’s geological structure.
