Gravity map
Gravity map: NASA's GRACE mission already produces maps of the Earth's changing gravitational field every 30 days. Changes indicate the movement of water, highlighting shrinking polar ice caps and rising sea levels. A new laser interferometer system to improve the precision of the system will be launched on board the GRACE-FO mission, set for 2017. Image: NASA JPL.
