The Spitzer Space Telescope mission
The Spitzer Space Telescope, NASA's Great Observatory for infrared astronomy, was launched 2003 August 25 and is returning excellent scientific data from its Earth-trailing solar orbit. SpitzerExpand
Voyager 2 at Neptune: Imaging Science Results
Voyager 2 images of Neptune reveal a windy planet characterized by bright clouds of methane ice suspended in an exceptionally clear atmosphere above a lower deck of hydrogen sulfide or ammonia ices.Expand
Surface Ices and the Atmospheric Composition of Pluto
Observations of the 1.4- to 2.4-micrometer spectrum of Pluto reveal absorptions of carbon monoxide and nitrogen ices and confirm the presence of solid methane. Frozen nitrogen is more abundant thanExpand
Laboratory experiments of Titan tholin formed in cold plasma at various pressures: implications for nitrogen-containing polycyclic aromatic compounds in Titan haze
Titan, the largest satellite of Saturn, has a thick nitrogen /methane atmosphere with a thick global organic haze. A laboratory analogue of Titan’s haze, called tholin, was formed in an inductivelyExpand
Infrared observations of the saturnian system from voyager 1.
TLDR
During the passage of Voyager 1 through the Saturn system, the infrared instrument acquired spectral and radiometric data on Saturn, the rings, and Titan and other satellites, implying a depletion of helium in the atmosphere of Saturn relative to that of Jupiter. Expand
2060 Chiron: Colorimetry and cometary behavior
Abstract VRIJHK colorimetry of “asteriod” 2060 Chiron in 1988 resolves a long-standing ambiguity about the fit of the visible spectrum to the infrared spectrum confirming that Chiron's spectrum isExpand
The Pluto system: Initial results from its exploration by New Horizons
TLDR
The New Horizons encounter revealed that Pluto displays a surprisingly wide variety of geological landforms, including those resulting from glaciological and surface-atmosphere interactions as well as impact, tectonic, possible cryovolcanic, and mass-wasting processes. Expand
Ices on the Surface of Triton
TLDR
The near-infrared spectrum of Triton reveals ices of nitrogen, methane, carbon monoxide, and carbon dioxide, of which nitrogen is the dominant component, which challenges existing models of methane and nitrogen photochemistry on Tritons. Expand
The Cassini Visual And Infrared Mapping Spectrometer (Vims) Investigation
The Cassini visual and infrared mapping spectrometer (VIMS) investigation is a multidisciplinary study of the Saturnian system. Visual and near-infrared imaging spectroscopy and high-speedExpand
The Composition of Centaur 5145 Pholus
Abstract We present a new spectrum of the Centaur object 5145 Pholus between 1.15 and 2.4 μm. We model this, and the previously published (0.4- to 1.0-μm) spectrum, using Hapke scattering theory.Expand
