These animations show the change in the mass of the Antarctic Ice Sheet between January 2004 and June 2014 as measured by the pair of GRACE satellites. The 1-arc-deg NASA GSFC mascon solution data was resampled to a 5130 x 5130 data array using Kriging interpolation. A color scale was applied where blue values indicate an increase in the ice sheet mass while red shades indicate a decrease. In addition, a graph overlay shows the running total of the accumulated mass change in gigatons.
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.
