TL;DR: This work presents the first direct identification and mapping of both carbon dioxide and water ice in the martian high southern latitudes, at a resolution of 2 km, during the local summer, when the extent of the polar ice is at its minimum.

TL;DR: The OMEGA (Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activite) is a visible and near-IR mapping spectrometer, operating in the spectral range 0.385-1 μm as discussed by the authors.
Journal ArticleDOI
A comparison of the atmospheres of Jupiter and Saturn: deep atmospheric composition, cloud structure, vertical mixing, and origin
Sushil K. Atreya,Michael H. Wong,Tobias Owen,Paul R. Mahaffy,Hasso B. Niemann,I. de Pater,Pierre Drossart,T. Encrenaz +7 more
TL;DR: The current understanding of the composition, vertical mixing, cloud structure and the origin of the atmospheres of Jupiter and Saturn is presented and a much more vigorous vertical mixing in Saturn's middle-upper atmosphere than in Jupiter's is pointed to.
Journal ArticleDOI
External supply of oxygen to the atmospheres of the giant planets
Helmut Feuchtgruber,E. Lellouch,T. de Graauw,Bruno Bézard,T. Encrenaz,Matthew Joseph Griffin +5 more
TL;DR: The detection of gaseous H2O in the upper atmospheres of Saturn, Uranus and Neptune is reported by infrared spectroscopy and may help to constrain the injection rate and possible activity of distant icy objects in the Solar System.
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.
