Since the beginning of 2019, InSight has detected more than 700 vibrations on Mars.

Scientists say they have some absolute data to describe the inner rock structure of Mars. The data comes from the InSight probe, which has been detecting vibrations on Mars since early 2019.

NASA led the mission, which showed that the average thickness of the Martian crust is between 15 miles and 45 miles, which is thinner than expected.

But the key finding is the size of the core of Mars, with a radius of 1,830 kilometers, which is on top of previous estimates.

This is the first time that the scientific community has managed to directly map the inner layered structure of planets other than Earth. Scientists have done similar things on the Moon before, but the scale of Mars (total radius: 3,390 kilometers) is much larger.
