Marsquakes: InSight lander shows active faults in planet’s crust

The results from its NASA’s Mars InSight lander’s first 10 months on the martian surface have been published in a series of papers. Source: https://earthsky.org/space/mars-quakes-insight-lander-shows-active-faults…

The seismicity of Mars

On 26 November 2018, the NASA InSight lander successfully set down on Mars in the Elysium Planitia region. Seventy Martian days later, the mission’s seismometer SEIS began recording the planet’s vibrations. A team of researchers and engineers at ETH Zurich, led by ETH Professor Domenico Giardini, had delivered the SEIS control electronics and is responsible for the Marsquake Service. The latter…

Journey to the center of Mars: A new compositional model for the red planet

While InSight’s seismometer has been patiently waiting for the next big marsquake to illuminate its interior and define its crust-mantle-core structure, two scientists, Takashi Yoshizaki (Tohoku University) and Bill McDonough (Tohoku University and University of Maryland, College Park), have built a new compositional model for Mars. They used rocks from Mars and measurements from orbiting satellites to predict the depth to…

What does a marsquake feel like?

Quakes look and feel different depending on the material their seismic waves pass through. This new video compares marsquakes to moonquakes and quakes here on Earth. Source: https://earthsky.org/space/what-does-marsquake-feel-like-video…
