The rainy and dry seasons in the Amazon Basin in 2004, revealed by gravity anomalies observed by GRACE. Reds and pinks show where and when mass was higher than average, a sign that more water was present, and blues show months when mass was lower.
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.
