Nasa tracking Earth's weight: Melting ice, oceans move planet's centre of mass
Nasa scientists have developed a more precise way to measure Earth's seasonal geocentre shifts. The findings sharpen satellite and mapping reference systems while showing how water, ice and air move the planet's mass.
NASA Watches Earth’s Weight, Finds Center of Mass
Seasonal changes redistribute enough water around Earth to shift the planet’s center of mass back and forth by fractions of an inch relative to its geometric center. NASA scientists are on the case, tracking the oscillations because Earth’s center of mass is a crucial reference point for satellite navigation and elevation measurements. A team, led […]
The Earth's mass center is constantly shifting relative to its geometric center by a few millimeters, and NASA scientists have developed a new way to track these seasonal fluctuations with high accuracy by satellite.
