NASA and Germany to launch water-tracking satellite duo from 2028

NASA and the German Space Agency at DLR signed an agreement in late 2023 to jointly build, launch, and operate twin spacecraft that will measure monthly shifts in Earth's gravity field. The Gravity Recovery and Climate Experiment-Continuity mission, known as GRACE-C, extends a record stretching back to 2002. It will track where water moves between oceans, underground aquifers, atmosphere, and ice sheets. Targeting launch no earlier than 2028, the mission will carry on work the agency calls "key information in characterising Earth's climate," used for drought forecasting, agricultural water planning, and understanding sea level rise.
Farmers, water managers, and coastal communities will have another generation of data to plan around shrinking water supplies.
