Mars intenal structure, showing the basal molten layer of the mantle

Caption

Artist's view of the internal structure of Mars showing the propagation of diffracted waves from the September 2021 meteorite impact to the SEIS seismometer of the InSight mission. Their trajectory passes through the lower, completely molten part of the silicate layer at the base of the mantle, where seismic velocities are low.
