Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on European Space Agency's Express spacecraft provides new information Mars' geological and climatic history. Phyllosilicates formed aqueous alteration very early in planet's history (the “phyllocian” era) are found oldest terrains; sulfates were a second era “theiikian” an acidic environment. Beginning about 3.5 billion years ago, last “siderikian”) is dominated...
The VIRTIS (Visible, Infrared and Thermal Imaging Spectrometer) instrument on board the Rosetta spacecraft has provided evidence of carbon-bearing compounds nucleus comet 67P/Churyumov-Gerasimenko. very low reflectance (normal albedo 0.060 ± 0.003 at 0.55 micrometers), spectral slopes in visible infrared ranges (5 to 25 1.5 5% kÅ(-1)), broad absorption feature 2.9-to-3.6-micrometer range present across entire illuminated surface are compatible with opaque minerals associated nonvolatile...
Observations of Saturn's satellite Enceladus using Cassini's Visual and Infrared Mapping Spectrometer instrument were obtained during three flybys in 2005. Enceladus' surface is composed mostly nearly pure water ice except near its south pole, where there are light organics, CO2, amorphous crystalline ice, particularly the region dubbed "tiger stripes." An upper limit 5 precipitable nanometers derived for CO atmospheric column above Enceladus, 2% NH3 global deposits. Upper limits 140 kelvin...
The Visible, InfraRed, and Thermal Imaging Spectrometer (VIRTIS) on Rosetta obtained hyperspectral images, spectral reflectance maps, temperature maps of the asteroid 21 Lutetia. No absorption features, either silicates or hydrated minerals, have been detected across observed area in range from 0.4 to 3.5 micrometers. surface reaches a maximum value 245 kelvin correlates well with topographic features. thermal inertia is 20 30 joules meter(-2) kelvin(-1) second(-0.5), comparable lunarlike...
Abstract The SIMBIO-SYS (Spectrometer and Imaging for MPO BepiColombo Integrated Observatory SYStem) is a complex instrument suite part of the scientific payload Mercury Planetary Orbiter mission, last cornerstone missions European Space Agency (ESA) Horizon + science program. will provide all imaging capability spacecraft. It consists three channels: STereo Channel (STC), with broad spectral band in 400-950 nm range medium spatial resolution (at best 58 m/px), that Digital Terrain Model...
Spectra from Cassini's Visual and Infrared Mapping Spectrometer reveal that the horizontal structure, height, optical depth of Titan's clouds are highly dynamic. Vigorous cloud centers seen to rise middle upper troposphere within 30 minutes dissipate next hour. Their development indicates evolve convectively; through rain; and, over several hours, waft downwind achieve their great longitude extents. These other characteristics suggest temperate originate circulation-induced convergence, in...
Since the orbital insertion of Rosetta spacecraft, comet 67P/Churyumov-Gerasimenko (67P/C-G) has been mapped by OSIRIS camera and VIRTIS spectro-imager, producing a huge quantity images spectra comet's nucleus. The aim this work is to search for presence H$_2$O on nucleus which, in general, appears very dark rich dehydrated organic material. After selecting bright spots which could be good candidates ice, taken at high resolution OSIRIS, we check spectral cubes selected coordinates identify...
Rosetta observes sublimating surface ices Comets are “dirty snowballs” made of ice and dust, but they dark because the sublimates away, leaving some dust behind on surface. The spacecraft has provided a close-up view comet 67P/Churyumov-Gerasimenko as it passes through its closest point to Sun (see Perspective by Dello Russo). Filacchione et al. detected spectral signature solid CO 2 (dry ice) in small patches nucleus emerged from local winter. By modeling how sublimates, constrain...
The Visual and Infrared Mapping Spectrometer (VIMS) instrument aboard the Cassini spacecraft obtained its first spectral map of satellite Iapetus in which new absorption bands are seen spectra both low-albedo hemisphere H2O ice-rich hemisphere. Carbon dioxide is identified material, probably as a photochemically produced molecule that trapped ice or some mineral complex organic solid. Other unidentified. spectrum satisfactorily modeled with combination tholin, poly-HCN, small amounts Fe2O3....
Observations from the Cassini Visual and Infrared Mapping Spectrometer show an anomalously bright spot on Titan located at 80 degrees W 20 S. This area is in reflected light all observed wavelengths, but most noticeable 5 microns. The associated with a surface albedo feature identified images taken by Imaging Science Subsystem. We discuss various hypotheses about source of spot, reaching conclusion that probably due to variation composition, perhaps recent geophysical phenomena.
