NASAs Gravity Recovery and Climate Experiment (GRACE) has measured significant groundwater depletion around the world in recent years. These animations show trends in total water storage from January 2003 to December 2009 as measured by GRACE, depicting accumulated groundwater losses over time in Australia, California's Central Valley and the Middle East, and monthly anomalies in total water storage over the same timeframe in the Indian subcontinent.
When a mission exceeds expectations, it’s only reasonable to continue pushing the boundaries of spaceborne engineering and science. GRACE Follow-On carries technological upgrades that should give scientists an even clearer picture of climate change.
For the first time, scientists have detected sea level "fingerprints" – patterns of variation in global sea level due to changes in water and ice on land – in GRACE data.
Airbus tests the dispenser structure that will hold the twin GRACE-FO satellites during their launch.
"With GRACE, we effectively created a new field of spaceborne remote sensing: tracking the movement of water via its mass," said Michael Watkins, the original GRACE project scientist and now director of NASA's Jet Propulsion Laboratory, Pasadena, California.
Iridium announces that it has purchased an additional Falcon 9 launch from SpaceX that the satellite services company will share with the GRACE-FO mission.
