Recently Launched Twin Satellites Create 'The Himalaya Plot'

June 11, 2018

Along NASA's GRACE-FO satellites' ground track (top), the inter-spacecraft distance between them changes as the mass distribution underneath (i.e., from mountains, etc.) varies.

GRACE-FO has completed its first mission phase and demonstrated the performance of the precise ranging system that enables its measurements of how mass migrates around Earth.

Along the satellites' ground track (top), the inter-spacecraft distance between them changes as the mass distribution underneath (i.e., from mountains, etc.) varies. The small changes measured by the Microwave Ranging Instrument (middle) agree well with topographic features along the orbit (bottom).

GRACE-FO continues a successful partnership between NASA and Germany's GFZ, with participation by the German Aerospace Center (DLR). JPL manages the mission for NASA's Science Mission Directorate in Washington.
