Abstract
A near-infrared mapping spectometer is included in the science complement of the Galileo Mission, which will explore Jupiter and its satellites in the mid-1980s. The objectives of the infrared mapping spectrometer experiment are to map compositional units on the surfaces of the Jovian satellites and to characterize the mineral content of these units. For Jupiter's atmosphere, this experiment will investigate such areas as cloud properties and the spatial and temporal variability of minor species. The instrument consists of a telescope, a plane grating spectrometer, a Si and InSb detector array, and a passive radiative cooler. The spectral range is 0.7 - 5.2 μ, covered with a resolution of 0.025 μ. A wobbling secondary mirror in the telescope provides one dimension of spatial scanning, while the other dimension is provided by motion of the spacecraft scan platform.
