What can over 1,300 marsquakes reveal about the interior of the Red Planet?

After landing on Mars in 2018, NASA's InSight mission transformed our understanding of the planet's internal structure. This expert Q&A explores how the lander's seismic data continues to provide insights into the Martian crust, mantle, and core long after the mission's conclusion.

Since its arrival in 2018, InSight has recorded more than 1,300 marsquakes. This seismic activity has been instrumental in allowing researchers to map the depth and composition of Mars' internal layers, including its crust, mantle, and core.

The mission also utilized a twin model named ForeSight, housed at the In-Situ Instrument Laboratory at NASA's Jet Propulsion Laboratory, to assist the engineering team. While the lander's power eventually diminished, the data collected remains a vital resource that scientists expect to study for years to come.
