Journal ArticleDOI
Non‐water‐ice constituents in the surface material of the icy Galilean satellites from the Galileo near‐infrared mapping spectrometer investigation
T. B. McCord,Gary B. Hansen,Roger N. Clark,Patrick Martin,Charles A. Hibbitts,F. P. Fanale,J. C. Granahan,M. Segura,Dennis L. Matson,T. V. Johnson,Robert W. Carlson,William D. Smythe,G. E. Danielson +12 more
TL;DR: In this article, the authors present evidence for several non-ice constituents in the surface material of the icy Galilean satellites, using the reflectance spectra returned by the Galileo near infrared mapping spectrometer (NIMS).
Journal ArticleDOI
Organics and Other Molecules in the Surfaces of Callisto and Ganymede
Thomas B. McCord,R. W. Carlson,William D. Smythe,Gary B. Hansen,Roger N. Clark,Charles A. Hibbitts,F. P. Fanale,J. C. Granahan,M. Segura,Dennis L. Matson,Torrence V. Johnson,Patrick Martin +11 more
TL;DR: Analysis of reflectance spectra returned by the Galileo mission near-infrared mapping spectrometer indicates that the primary surface constituents of the Galilean satellites Callisto and Ganymede are water ice and hydrated minerals.
Journal ArticleDOI
Near-Infrared Spectroscopy and Spectral Mapping of Jupiter and the Galilean Satellites: Results from Galileo's Initial Orbit
Robert W. Carlson,William D. Smythe,Kevin H. Baines,E. Barbinis,Kris J. Becker,R. Burns,S. B. Calcutt,Wendy M. Calvin,Roger N. Clark,G. E. Danielson,A. G. Davies,Pierre Drossart,T. Encrenaz,Fraser P.

Weissman +39 more
TL;DR: Spectra for a 5-micrometer hot spot on Jupiter are consistent with the absence of a significant water cloud above 8 bars and with a depletion of water compared to that predicted for solar composition, corroborating results from the Galileo probe.
Journal ArticleDOI
Io in the near infrared: Near‐Infrared Mapping Spectrometer (NIMS) results from the Galileo flybys in 1999 and 2000
Rosaly M. C. Lopes,L. W. Kamp,Sylvain Douté,William D. Smythe,Robert W. Carlson,Alfred S. McEwen,Paul Geissler,Susan W. Kieffer,F. Leader,A. G. Davies,E. Barbinis,R. Mehlman,M. Segura,James H. Shirley,L. A. Soderblom +14 more
TL;DR: Galileo's Near-Infrared Mapping Spectrometer (NIMS) was used to map the detailed thermal structure of active volcanic regions and the surface distribution of SO2 and to investigate the origin of a yet unidentified compound showing an absorption feature at 1 m as mentioned in this paper.
Journal ArticleDOI
A close-up look at Io from Galileo's near-infrared mapping spectrometer.
R. Lopes-Gautier,Sylvain Douté,William D. Smythe,L. W. Kamp,Robert W. Carlson,A. G. Davies,F. Leader,Alfred S. McEwen,Paul Geissler,Susan W. Kieffer,Laszlo P. Keszthelyi,E. Barbinis,R. Mehlman,M. Segura,James H. Shirley,L. A. Soderblom +15 more
TL;DR: Infrared spectral images of Jupiter's volcanic moon Io, acquired during the October and November 1999 and February 2000 flybys of the Galileo spacecraft, were used to study the thermal structure and sulfur dioxide distribution of active volcanoes.
