The Gravity Recovery and Climate Experiment (GRACE) mission uses a pair of satellites launched in March 2002 to make detailed measurements of Earth's gravity field. These observations include gravity variations due to changes in the surface and deep currents in the ocean. GRACE is jointly implemented by NASA and the Deutschen Zentrum für Luft-und Raumfahrt (DLR).

  • The Center for Space Research at the University of Texas maintains the GRACE home page.
  • GRACE Tellus provides monthly estimates of changes in ocean mass.
