NSSDC ID: 1989-084E-05
Mission Name: Galileo Probe
Principal Investigator: Dr. Boris Ragent
The objective of this investigation is to determine vertical extent, structure, and microphysical characteristics (particle size distribution, number density, and physical structure) of Jupiter's clouds over the range 0.1 to 10 bars. A single-wavelength, multiple-angle (5) scattering nephelometer, with a gallium-arsenide LED (9000 A) source and solid-state detectors is mounted on the Probe, with appropriate external viewing geometry. Deployment takes place after the heat shield is removed. The total mass is 1.8 kg and the total continuous power is 3.0 W.
Mass: 4.4 kg
Power (avg): 11.3 W
Bit rate (avg): 0.01 bps
