NASA will host a media briefing at 10 a.m. PDT (1 p.m. EDT) Monday, April 30, to discuss the upcoming launch of a mission that will provide unique insights into our planet's changing climate and Earth system processes, and have far-reaching benefits to society, such as improving water resource management.

The briefing will be held at NASA Headquarters at 300 E St. SW in Washington, and air live on NASA Television and the agency's website. It will also be streamed live and archived at https://youtube.com/nasajpl/live.

The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission will measure and monitor monthly changes in how mass is redistributed within and among Earth's atmosphere, oceans, land and ice sheets, as well as within Earth itself. NASA's Jet Propulsion Laboratory in Pasadena, California, manages the mission for NASA's Science Mission Directorate in Washington.

The briefing participants are:

David Jarrett, GRACE-FO program executive in the Earth Science Division at NASA Headquarters, Washington

Michael Watkins, GRACE-FO science lead and director of NASA's Jet Propulsion Laboratory, Pasadena, California

Frank Webb, GRACE-FO project scientist at JPL

Phil Morton, NASA GRACE-FO project manager at JPL

Frank Flechtner, GRACE-FO project manager for the German Research Centre for Geosciences (GFZ), in Potsdam, Germany

Media and the public may ask questions during the briefing on Twitter using the hashtag #askNASA.

GRACE-FO is scheduled to launch May 19 from Vandenberg Air Force Base in California as a "rideshare" on a SpaceX Falcon 9 rocket carrying five Iridium communications satellites. GRACE-FO is a partnership between NASA and GFZ.
