GRACE Follow-On (GRACE-FO) continues the legacy of GRACE, tracking Earth’s water movement and surface mass changes across the planet. Monitoring changes in ice sheets and glaciers, near-surface and underground water storage, the amount of water in large lakes and rivers, as well as changes in sea level and ocean currents provides an integrated global view of how Earth’s water cycle and energy balance are evolving.
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.
