A new analysis of the seismic data gathered by the InSight lander reveals that marsquakes occur across a much larger area of the planet than previously believed.
The InSight Lander, on Mars, intentionally dumped sand over its seismic instrument’s tether and the wind sorted the particles by size as it blew them away.
The impact sent surface waves rippling over the Martian surface all the way to NASA’s InSight lander, giving scientists a rare view of the planet’s outer layer.
Seismic signals detected by the InSight lander show that the planet’s lower mantle may be less homogenous than previous models have suggested.
The first seismic observations from Mars significantly reduce uncertainty in estimates of the Red Planet’s crustal structure.
A secondary suite of instruments on the Mars lander produced a first look at magnetic fields from the planet’s surface.

InSight data hint that shifting carbon dioxide ice loads, illumination changes, or solar tides could drive an uptick in marsquakes during northern summer—a “marsquake season.”

Thanks to some extraordinary engineering, the InSight mission has led the new field of Martian seismology to the development of a new planetary magnitude scale in less than a year.
