Through international collaboration, scientists find cause of InSight’s most powerful Marsquake
An international team of scientists has found the cause of the largest Martian seismic event, or Marsquake, observed by NASA’s Interior Exploration using Seismic Investigations, Geodesy and Heat Transport (InSight) Mars lander. After ruling out a meteor impact, they concluded the event must have been caused by a release of stress within the planet’s crust.…

Perseverance finds Mars river could have been ‘wilder,’ Mars Express takes new volcano images
May has been a big month for scientific discoveries on Mars, as NASA’s Perseverance rover has continued to find more convincing evidence of what could have once been a “deeper and faster-moving” river than data initially suggested. New images taken by the rover’s main camera show two mosaics of course sediment grains and tall, curving…

Perseverance’s first sample collection fails, new science points to subsurface Martian clay lakes
NASA’s Perseverance Mars rover recently attempted its first-ever sample collection of the Martian surface on August 6. However, data shows that while the rover’s drill successfully drilled into the surface, no regolith was collected in the sample tube. Meanwhile, as Perseverance was preparing for the sample collection event, a team of researchers using ESA’s Mars…

Mars Express and the case of the large, mysterious Martian volcano cloud
Throughout the southern Martian hemisphere’s spring and summer seasons, a large, expansive cloud emerges daily from the volcano Arsia Mons. Why this cloud only forms at this location on Mars, what kind of cloud it is, and other puzzles to this phenomenon have plagued researchers for years — as observing Martian weather usually only happens…

ESA science missions back in action after coronavirus-related shutdown
Artist’s concept of the ExoMars Trace Gas Orbiter. Credit: ESA/ATG medialab Four of the European Space Agency’s robotic missions, including the agency’s two Mars orbiters, are resuming science operations after a stand-down triggered by the positive diagnosis of an employee at ESA’s control center in Germany with the coronavirus. ESA said Thursday that the four…

Mars Express water discovery reopens intriguing questions for future Martian Exploration
For the first time in human exploration of Mars, the presence of a stable, subterranean body of salty (briny) water has been strongly suggested by data returned by the European Space Agency’s Mars Express orbiter. Using measurements taken by the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument, a team of Italian researches…
