(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 ...

Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...

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 ...

When it comes to understanding the fundamental forces of the universe, gravity is by far the most intuitive. It’s the force that brings us splashing down after jumping from a diving board and the ...

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 ...

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 ...

A new space probe could soon transform how we study distant planets without ever landing on them. The Gravity Imaging Radio Observer, or GIRO, is a proposed NASA concept that aims to map the interiors ...

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, ...

An object hidden below ground has been located using quantum technology – a long-awaited capability with significant implications for industry, security and human knowledge. Researchers at the ...

Ocean explorers have long tried to survey the contours of the seafloor, but today's charts still pale in comparison to those of distant planets. By Bill Gourgey Published Sep 14, 2022 10:00 AM EDT Get ...
