The satellites were subsequently stacked atop another satellite dispenser containing the five Iridium NEXT communications satellites they will share a ride to orbit with.

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.
