The GRACE-A and B Microwave Assemblies (MWA) have been switched-on again on 17 March (the 15th birthday of the satellite mission!) and began operations in sunlight.

Time tagged commands were uploaded to begin sunlight operations at 11:16 UTC. The MWA is currently on for 42 minutes per orbit. MWA on time will increase each day as eclipse durations shorten.
