A team of scientists used data from NASA's InSight Mars lander to shed new light on the liquid core at the center of the Red Planet.
By analyzing the InSight lander data, they were able to determine that the Martian core is slightly denser and smaller than previously believed.mission was initially intended to last approximately one Mars year, roughly equivalent to two Earth years. However, it exceeded NASA's expectations and lasted roughly four years, allowing scientists to tap into a wealth of extra data.
Aside from finding that Mars' liquid core is a little smaller than previously believed, the scientists also found that Mars' core contains large amounts of sulfur and small amounts of hydrogen on top of the iron they expected to detect in large quantities.The team behind the new analysis comprised a multi-disciplinary team, including seismologists, geodynamicists, and mineral physicists.
