GRACE-C is a successor to the original GRACE and GRACE-FO missions, which orbited Earth from 2002 to the present day. GRACE-C will provide month-to-month changes of Earth's gravity field to track water movement and surface mass changes across the planet, monitoring variations in ice sheets, glaciers, underground water storage, soil moisture, and sea levels. These data provide an integrated global view of how Earth’s water cycle and water resources are evolving — measurements that have important applications for everyday life.
