Galileo NIMS: New ISIS3 tools for modernized data set handling and PDS4 re-archival

Given the renewed interest in the outer solar system by NASA, including efforts toward developing viable Europa orbital and lander missions and line items in the decadal survey calling for an Io Observer mission [1], previous data sets of these bodies are extremely important for planning, targeting, and continued scientific analysis leading up to execution of these mission efforts in the coming years. Galileo data is a good example of a data set that could yield more information moving into the future if a greater number of the community can easily access and use it. Galileo collected monochrome and multispectral visible data with the Solid State Imager (SSI) and hyperspectral near-infrared reflectance spectra with the Near-Infrared Mapping Spectrometer (NIMS) of numerous planetary bodies including several of Jupiter’s Moon’s (e.g., Io and Europa). In the context of Io, recent efforts by Becker and Geissler [2] and Williams et al. [3] have made some great initial progress integrating Galileo SSI and Voyager data into global data products capable of discriminating albedo, color, and morphology. These products are now available as ArcGIS products to the planetary community (http://pubs.usgs.gov/sim/3168/). Similar efforts to spatially register Voyager and Galileo SSI imagery of Europa have also been successful [4, 5]. However, similar comprehensive efforts have yet to be made and delivered to the PDS for Galileo NIMS data, the only hyperspectral imaging observations of outer solar system bodies. Here we have made an effort to remedy this situation transitioning the data set to PDS4 with ISIS3 processing support.
