Page "Galileo (spacecraft)" Paragraph 49

The despun section's instruments included the camera system ; the near infrared mapping spectrometer to make multi-spectral images for atmospheric and moon surface chemical analysis ; the ultraviolet spectrometer to study gases ; and the photo-polarimeter radiometer to measure radiant and reflected energy.

The camera system was designed to obtain images of Jupiter's satellites at resolutions from 20 to 1, 000 times better than Voyager's best, because Galileo flew closer to the planet and its inner moons, and because the more modern CCD sensor in Galileos camera was more sensitive and had a broader color detection band than the vidicons of Voyager.
