Objectives and Applications Mass-change And Geoscience International Constellation (MAGIC) concept based on ESA’s Next Generation Gravity Missions (NGGM). The objective of MAGIC is the long-term accurate monitoring of the temporal variations of Earth’s gravity field at high resolution in time (down to 3 days) and in space. MAGIC will observe Earth mass change and reinforce services in hydrology, cryosphere, oceanography, solid Earth, climate change and geodesy. The observables are the variations of the distance between two satellites, measured by a laser interferometer with sub-nanometre precision, and non-gravitational accelerations, to be separated from the gravity signal in the data processing, measured by accelerometers on each satellite. MAGIC represents the natural evolution in the provision of enhanced continuity of science and services with respect to predecessor missions like GRACE, GOCE and GRACE-FO and will be complementary to other Earth Explorer and Copernicus missions. The improvements expected in terms of spatial, temporal resolution and measurement accuracy shall pave the way to novel science and operational applications, such as monitoring of extreme events, warning for drought and flood events as well as geohazards.
