(CNN) — By tracking the gravitational pull on spacecraft over Mars, NASA has created one of the most detailed maps yet of the Red Planet’s surface, and what lies beneath. “Gravity maps allow us to see ...

NASA scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution. A ...

A discovery about the moon made in the 1960s is helping researchers unlock secrets about Earth’s ocean today. By applying a method of calculating gravity that was first developed for the moon to data ...

Twin NASA probes orbiting the moon have generated the highest resolution gravity field map of any celestial body. The new map, created by the Gravity Recovery and Interior Laboratory (GRAIL) mission, ...

Earth is a lumpy, squishy place - or so the newest, best-ever gravity map of the planet has revealed. A flying pair of American and German satellites, known as GRACE, has measured the uneven gravity ...

This is a Martian gravity map showing the Tharsis volcanoes and surrounding flexure. The white areas in the center are higher-gravity regions produced by the massive Tharsis volcanoes, and the ...

The first global gravity model based on GOCE satellite data has been presented at ESA’s Living Planet Symposium. ESA launched GOCE in March 2009 to map Earth’s gravity with unprecedented accuracy and ...
