GRACE operational issue: Planned switch-on of MWA
20 March 2017
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.
The GRACE-B Accelerometer Instrument Control Unit (ICU) remains off.
Top story on Copernicus

After being put through its paces to make sure it is fit for life in orbit around Earth, the Copernicus Sentinel-3B satellite is ready to be packed up and shipped to Russia for liftoff.
Its twin, Sentinel-3A, has been in orbit since February 2016, systematically measuring our oceans, land, ice and atmosphere. The information feeds a range of practical applications and is used for monitoring and understanding large-scale global dynamics.
