Objectives and Applications
Mass-change And Geoscience International Constellation (MAGIC) concept based on NASA's Mass Change Designated Observable mission (MCDO). MAGIC/MCDO 2-sat constellation will measure fluctuations in Earth’s gravitational field, allowing the study of hydrological phenomena such as mass transport, as well as building on the success of previous missions in the field, such as the Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission, the Gravity Recovery and Climate Experiment (GRACE), and its follow-on mission, GRACE-FO. MAGIC will provide data continuity for the mass transport time series from these missions, as well as improvements in the temporal and spatial resolution of gravitational field mapping. This greater resolution in mapping Earth’s gravitational field will also allow enhanced study of mass transport, the shift of water mass between phases of the global water cycle, as mass transport has a calculable impact on gravitational field fluctuations.
