This map from September 2015 shows deep drought in California, Nevada and Texas. While the GRACE mission was active, scientists at NASA’s Goddard Space Flight Center generated groundwater and soil moisture drought indicators like this every week from GRACE data on terrestrial water storage and other observations, using a numerical model of land surface water and energy processes. They will resume producing maps when GRACE-FO data are available.
NASA's GRACE-FO team plans to switch to a backup system in the Microwave Instrument on one of the twin spacecraft this month.
The laser ranging interferometer (LRI) instrument has been successfully switched on aboard the recently launched twin U.S./German Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) satellites.
Antarctic ice losses have tripled since 2012, raising global sea levels by 0.12 inch (3 millimeters) in that timeframe alone, finds a new NASA/ESA-funded climate assessment.
GRACE-FO has completed its first mission phase and demonstrated the performance of the precise ranging system that enables its measurements of how mass migrates around Earth.
All flight and ground systems have performed well throughout the Launch and Early Operations Period. The accelerometer and microwave science instruments have been powered on successfully and the two satellites are in relative pointing mode.
