Mars Express Finds New Evidence for Ice-Rich Layered Deposits in Medusae Fossae
Over 15 years ago, ESA’s Mars Express spacecraft studied the Medusae Fossae Formation, revealing enigmatic deposits up to 2.5 km deep. From those early observations, it was unclear what the…
InSight’s Largest Marsquake Was Likely Caused by Geological Processes, Study Says
During its time on Mars, NASA’s InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander recorded over 1,300 seismic events, known as marsquakes. Of these, a number were…
ESA’s Mars Express Focuses on Surroundings of Olympus Mons Volcano
Lava flows on Olympus Mons probably melted ice in the ground, making the volcano flank unstable; rockfalls and landslides moved hundreds of km into the surrounding landscape, forming a characteristic…
