Mars’s liquid iron core is smaller and denser than previously thought. Not only is it smaller, but it is also surrounded by a layer of molten rock. This is what ETH Zurich researchers conclude on the basis of seismic data from the InSight lander. One year after the NASA InSight Mission ended, t

Two analyses of seismic waves that traversed Mars paint the clearest picture yet of the red planet’s core and deep mantle — and rationalize the puzzling implications of a previous interpretation of the seismological data. The red planet’s core is surrounded by a layer of molten rock.

A layer of molten rock above the core led to confusing seismic signals.

Mars's core is a huge, light ball of liquid iron - or so we thought. Find out what scientists now think is happening inside the Red Planet.
