Description:
The payloads, mission, and performance characteristics of the Galileo probe, to be launched by a Centaur boost from the Orbiter in 1985, are described. The Galileo is intended to determine the chemical compositions and physical states of the Jovian atmosphere and of the Jovian satellites, and to investigate the structure and dynamics of the Jovian magnetosphere. The orbiting part of the spacecraft will carry a near-IR mapping spectrometer, a photopolarimeter radiometer, a solid state imaging camera, a UV spectrometer, and five fields and particles instruments. A probe will be dropped for parachute descent into the Jovian atmosphere, carrying an atmospheric structure instrument, a neutral mass spectrometer, a He abundance interferometer, a nephelometer, and a radiometer. A retrorocket burn during the encounter with Jupiter will place the Galileo in an orbit calculated to pass close to all the Jovian moons over 12 orbits spanning 20 mos.
