- A team of NASA scientists has proposed the deployment of a Quantum Gravity Gradiometer (QGG) onboard a satellite in low-Earth orbit.
- It aims to detect minute gravitational variations on Earth.
- It would allow for precise monitoring of the planet’s subsurface mass distribution, aiding in climate studies and enhancing national security.
- It is a highly sensitive scientific instrument used to measure the variation in the gravitational acceleration over a specific distance.
- Based on the Newton’s second law (F = ma), the Gravity Gradiometer detects the variations in gravitational force and acceleration caused by changes in local mass distribution.
