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...
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...
On 4 July 2005, many observatories around the world and in space observed collision of Deep Impact with comet 9P/Tempel 1 or its aftermath. This was an unprecedented coordinated observational campaign. These data show that (i) there new material after impact compositionally different from seen before impact; (ii) ratio dust mass to gas ejecta much larger than (iii) activity did not last more a few days, by 9 comet's behavior indistinguishable pre-impact behavior; (iv) were interesting...
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...
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...
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...
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...
We investigated the origin of unusual pitted terrain on asteroid Vesta, revealed in images from Dawn spacecraft. Pitted is characterized by irregular rimless depressions found and around several impact craters, with a distinct morphology not observed other airless bodies. Similar associated numerous martian where pits are thought to form through degassing volatile-bearing material heated impact. Vesta may have formed similar manner, which indicates that portions surface contain relatively...
Abstract The Dawn spacecraft mission has provided extensive new and detailed data on Vesta that confirm strengthen the Vesta–howardite–eucrite–diogenite ( HED ) meteorite link concept is differentiated, as derived from earlier telescopic observations. Here, we present results by newly calibrated spectra of Vesta. comparison between imaging spectrometer— VIR —and different class meteorites shows average spectrum resembles howardite spectra. Nevertheless, at high spatial resolution reveal...
TandEM was proposed as an L-class (large) mission in response to ESA's Cosmic Vision 2015–2025 Call, and accepted for further studies, with the goal of exploring Titan Enceladus. The concept is perform situ investigations two worlds tied together by location properties, whose remarkable natures have been partly revealed ongoing Cassini–Huygens mission. These bodies still hold mysteries requiring a complete exploration using variety vehicles instruments. ambitious because its targets are most...
