It is a follow-on in respect of the GRACE Satellite which is scheduled for launch on May 19th. The main objective of the mission will be to track the changes that are taking place in glaciers, lakes and rivers, sea levels. This helps us to understand that how earth's water in motion can help us to find out ... NASA
For example, scientists use data from the U.S.-German GRACE satellite mission to measure the mass of the land ice in both the Arctic and Antarctic.

The two GRACE satellites -GRACE-1 and GRACE-2 - were launched aboard a launch vehicle from Plesetsk Cosmodrome, Russia on March 17, 2002. • Since their launch, the twin satellites took detailed measurements of Earth's gravity field anomalies and their data transformed scientists' view of ...
The first, called Gravity Recovery and Climate Experiment Follow-On, or GRACE-FO, is expected to launch this spring.

Research led by The University of Texas at Austin has found that calculations of water storage in many river basins from commonly used global computer models differ markedly from independent storage estimates from GRACE satellites. The findings, published in the Proceedings of the National Academy ...
The researchers used the GRACE satellites to take precise measurements of the world's groundwater aquifers and detected subtle changes in the Earth's gravitational pull, noting where the heavier weight of water exerted a greater pull on the orbiting spacecraft. The study ran from 2003 to 2013 and found ...
Unfortunately for UFO enthusiasts, it was quickly revealed that the weird, box-shaped objects weren't alien spacecraft at all—they were NASA's two GRACE satellites, whose names stand for "Gravity Recovery and Climate Experiment." Scott Brando, a UFO debunker, gets credit for revealing the truth.
Some of those already satisfy priorities laid out in the latest report, such as the planned launch—no earlier than March—of the next pair of US–German GRACE satellites. The probes are designed to measure variations in gravity to calculate shifts in mass on the Earth's surface, such as those that occur when ...
