Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander.

Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had suggested, and is somewhat larger than expected.

InSight reached Mars in late 2018 and soon afterward detected the first known marsquake.

Since then, the lander’s instruments have picked up more than a thousand temblors, most of them minor rumbles.

Many of those quakes originated at a seismically active region more than 1,000 kilometers away from the lander.

Seismic waves (red lines in this illustration) traveling through Mars from a quake’s source (example, red dot) to the InSight lander (white dot) reveal the Red Planet’s internal structure, including a massive core (yellow-white) more than half the diameter of the planet.
