After GRACE-FO launches and science operations commence in early 2018, this page will provide regular (at least monthly) updates from surface mass anomalies as observed with GRACE-FO. These data will inform hydrologists about up-to-date land water storage conditions, provide glaciologists with accurate measurements of glacier and ice sheet mass changes, and allow oceanographers to asses global and regional sea level and ocean current variations.
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.
