The Gravity Recovery and Climate Experiment (GRACE) was selected under the NASA Earth System Science Pathfinder (ESSP) program with the goal of observing the static and time-variable gravity field with an unprecedented level of accuracy over the course of the five-year mission. The GRACE mission, successfully launched on March 17, 2002, consists of two satellites, co-orbiting in a polar orbit and separated by 200 km. Each satellite carries a microwave, dual frequency one-way ranging system, which is providing measurements of the differential satellite perturbations due to variations in the gravity field. Each satellite carries a high precision accelerometer and a GPS receiver to aid in the recovery of the gravity field from the observational data. The extended mission life coupled with the precision of the measurements is expected to provide a static gravity field model which is several orders of magnitude more accurate than current models and will provide measurements of the temporal variations which will provide new insight into mass and momentum transport among the Earth's atmosphere, ocean and land components. The mission, which is one of the first NASA Earth System Pathfinder Missions, is implemented through a collaborative arrangement by NASA and DLR. The presentation will summarize the mission status and will describe some of the preliminary analysis results.
