Constraining Time Variations in Enceladus’ Water-Vapor Plume With Near-Infrared Spectra from Cassini-VIMS
Water vapor produces a series of diagnostic emission lines in the near infrared between 2.60 and 2.75 microns. The Visual and Infrared Mapping Spectrometer (VIMS) onboard the Cassini spacecraft detected […]
