NASA Administrator Jim Bridenstine talks about the GRACE Follow-on (GRACE-FO) mission to track Earth’s water movement. GRACE-FO is scheduled to launch May 22, 2018 aboard a SpaceX Falcon 9 rocket from Vandenberg Air Force Base, California. The mission will monitor changes in underground water storage, the amount of water in ice sheets and glaciers and sea level caused by the addition of water to the ocean.
