NASA’s GRACE-FO Prepares for Launch NASA Jet Propulsion Laboratory

The twin satellites of NASA's Gravity Recovery and Climate Experiment Follow-on, or GRACE-FO, will track the movement of water around Earth. This short video explains how and why it's important. 

Iridium-6/GRACE-FO Mission SpaceX

SpaceX is targeting launch of Iridium-6/GRACE-FO on Tuesday, May 22 from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base, California. The instantaneous launch opportunity is at 12:47 p.m. PDT, or 19:47 UTC. The GRACE-FO satellites will be deployed approximately eleven minutes and thirty seconds after launch, followed by the deployment of five Iridium® NEXT satellites beginning about an hour after launch.

A backup instantaneous launch opportunity is available on Wednesday, May 23 at 12:42 p.m. PDT, or 19:42 UTC.

Falcon 9’s first stage for the Iridium-6/GRACE-FO mission previously supported the Zuma mission from Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station in January 2018. SpaceX will not attempt to recover Falcon 9’s first stage after launch.

For 15 Years, GRACE Tracked Freshwater Movements Around the World

Between 2002 and 2016, the Gravity Recovery and Climate Experiment (GRACE) tracked the movement of freshwater around the planet. 

NASA scientists used GRACE data to identify regional trends of freshwater movement, and combined that information with data from other satellites, climate models and precipitation measurements to determine the causes of major regional trends in freshwater storage.
