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 assess global and regional sea level and ocean current variations.
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.
