NASA's New Gravity Map of Mars
on 24 March 2016
A new gravity map of Mars created by NASA provides the most detailed look at the Red Planet thus far. By analyzing gravitational anomalies across the planet’s surface (due to mountains, valleys and other topographic variations), researchers now have a better idea of the crustal thickness of Mars, and they were able to confirm that it contains a molten outer-core. The new gravity map is sure to be invaluable to future Mars exploration. Read more about NASA’s discoveries at its website.
