Two NASA missions collaborated to examine a novel marsquake type.

NASA and other space agencies closely monitor Mars, which is our closest neighbor. They can monitor the Red Planet's daily weather, just like our forecasts here on Earth,

and spot even minute changes on its surface thanks to over a dozen current missions in or around the planet.

The discovery of two new sizable impact craters in the Martian crust by the Mars Reconnaissance Orbiter (MRO) and the InSight lander, however, represents a considerably more significant change. 

Two recent articles appearing in the journal Science claim that these are the largest impact craters yet found by MRO and the first seismic surface wave detection.

Ingrid Daubar, planetary scientist at NASA's Jet Propulsion Lab and member of the MRO/InSight team, remarked in a NASA news briefing on the new findings

Quakes on Mars, like those brought on by these meteor strikes, shed more light on the planet's composition and the development of rocky planets like Earth.
