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...
A New Dawn Since 17 July 2011, NASA's spacecraft has been orbiting the asteroid Vesta—the second most massive and third largest in solar system (see cover). Russell et al. (p. 684 ) use Dawn's observations to confirm that Vesta is a small differentiated planetary body with an inner core, represents surviving proto-planet from earliest epoch of formation; also confirmed as source howardite-eucrite-diogenite (HED) meteorites. Jaumann 687 report on asteroid's overall geometry topography, based...
The processes that led to the formation of planetary bodies in Solar system are still not fully understood. Using results obtained with comprehensive suite instruments onboard European Space Agency's Rosetta mission, we present evidence comet 67P/Churyumov-Gerasimenko likely formed through gentle gravitational collapse a bound clump mm-sized dust aggregates ('pebbles'), intermixed microscopic ice particles. This scenario leads cometary make-up is simultaneously compatible global porosity,...
INTRODUCTION The surface of the dwarf planet Ceres is known to host phyllosilicate minerals, but their distribution and origin have not previously been determined. Phyllosilicates are hydrated silicates, presence on intriguing given that structure evolves through an aqueous alteration process. In addition, some phyllosilicates bear NH 4 , which places a constraint pH redox conditions during evolution Ceres. We studied across planet’s better understand evolutionary pathway RATIONALE Using...
Organic compounds detected on Ceres Water and organic molecules were delivered to the early Earth by impacts of comets asteroids. De Sanctis et al. examined infrared spectra taken Dawn spacecraft as it orbited Ceres, largest object in asteroid belt (see Perspective Küppers). In some small patches surface, they absorption bands characteristic aliphatic compounds. The authors ruled out an external origin, such impact, suggesting that material must have formed Ceres. Together with other...
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...
Water plays a key role in the evolution of terrestrial planets, and notably occurrence Earth's oceans. However, mechanism by which water has been incorporated into these bodies—including Earth—is still extensively debated. Here we report detection widespread 2.8 μm OH absorption bands on surface asteroid Vesta VIR imaging spectrometer board Dawn. These observations are surprising as is fully differentiated with basaltic surface. The distributed across Vesta's shows areas enriched depleted...
Before Rosetta, the space missions Giotto and Stardust shaped our view on cometary dust, supported by plentiful data from Earth based observations interplanetary dust particles collected in Earth’s atmosphere. The Rosetta mission at comet 67P/Churyumov-Gerasimenko was equipped with a multitude of instruments designed to study dust. While an abundant amount presented several individual papers, many focused dedicated measurement or topic. Different instruments, methods, sources provide...
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...
We examine the evolution of water production comet 67P/Churyumov–Gerasimenko during Rosetta mission (2014 June–2016 May) based on in situ and remote sensing measurements made by instruments, Earth-based telescopes through development an empirical coma model. The derivation model is described then applied to detrend spacecraft position effects from Orbiter Spectrometer for Ion Neutral Analysis (ROSINA) data. inter-comparison instrument data sets shows a high level consistency provides...
Different carbonates have been detected on Ceres, and their abundance spatial distribution mapped using a visible infrared mapping spectrometer (VIR), the Dawn imaging spectrometer. Carbonates are abundant ubiquitous across surface, but variations in strength position of spectral absorptions indicate composition amount these minerals. Mg-Ca all over localized areas show Na carbonates, such as natrite (Na2CO3) hydrated (for example, Na2CO3·H2O). Their geological settings accessory NH4-bearing...
Context. Since its rendezvous with comet 67P/Churyumov-Gerasimenko (67P), the Rosetta spacecraft has provided invaluable information contributing to our understanding of cometary environment. On board, VIRTIS and ROSINA instruments can both measure gas parameters in rarefied atmosphere, so-called coma, provide complementary results remote sensing situ measurement techniques, respectively. The data from suggest that source regions H2O CO2 are not uniformly distributed over surface nucleus...
We analyse the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) – Double Focusing Mass data between 2014 August 2016 February to examine effect of seasonal variations on four major species within coma 67P/Churyumov-Gerasimenko (H2O, CO2, CO, O2), resulting from tilt in orientation comet's spin axis. Using a numerical inversion, we derive non-uniform activity distribution at surface nucleus these species, suggesting that has not significantly been changed differences...
