On the 128th sol (Martian day) of its mission, NASA's InSight rover, using its seismometer pictured above, has captured evidence of an earthquake on Mars. Er, uh, a marsquake.
Hell yeah. "Marsquake" is the name of my garage band so this will only be a windfall for me.
In terms of rumble, this is a rather small seismic event (NASA notes that if this had happened in Southern California it would barely register on any given day against any of the many small shakes that happen every day). Read more about the event here at the Jet Propulsion Lab/NASA website.
Still waiting for a marsnado.
