The Magnetics, Altimetry, Gravity, and Imaging of Callisto (MAGIC) mission was conceived to fully characterize the properties of the Galilean moon Callisto from its deep interior to the icy shell. Three main instruments are included as a scientific payload. Extremely accurate measurements of Callisto s topography, magnetic field, and morphology are obtained by the onboard laser altimeter, magnetometer, and camera, respectively. The telecommunication system additionally enables gravity and radio science investigation. A precise characterization of long-And short-wavelength gravity anomalies afford powerful constraints on the internal differentiation and the properties of the hydrosphere. Together these datasets would resolve ambiguities inherent in Galileo flyby data, revealing Callisto s interior structure as well as the existence and properties of its postulated internal ocean.

Abstract
The Magnetics, Altimetry, Gravity, and Imaging of Callisto (MAGIC) mission was conceived to fully characterize the properties of the Galilean moon Callisto from its deep interior to the icy shell. Three main instruments are included as a scientific payload. Extremely accurate measurements of Callisto s topography, magnetic field, and morphology are obtained by the onboard laser altimeter, magnetometer, and camera, respectively. The telecommunication system additionally enables gravity and radio science investigation. A precise characterization of long-And short-wavelength gravity anomalies afford powerful constraints on the internal differentiation and the properties of the hydrosphere. Together these datasets would resolve ambiguities inherent in Galileo flyby data, revealing Callisto s interior structure as well as the existence and properties of its postulated internal ocean.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
