Abstract

Occator is a prominent, geologically young crater (1,6) (diameter ~90 km, 19.4° N, 239.0° E), and its brightest region (Fig. 1) is at the centre of the crater, close to [...], The typically dark surface of the dwarf planet Ceres is punctuated by areas of much higher albedo, most prominently in the Occator crater (1). These small bright areas have been tentatively interpreted as containing a large amount of hydrated magnesium sulfate (1), in contrast to the average surface, which is a mixture of low-albedo materials and magnesium phyllosilicates, ammoniated phyllosilicates and carbonates (2-4). Here we report high spatial and spectral resolution near-infrared observations of the bright areas in the Occator crater on Ceres. Spectra of these bright areas are consistent with a large amount of sodium carbonate, constituting the most concentrated known extraterrestrial occurrence of carbonate on kilometre-wide scales in the Solar System. The carbonates are mixed with a dark component and small amounts of phyllosilicates, as well as ammonium carbonate or ammonium chloride. Some of these compounds have also been detected in the plume of Saturn's sixth-largest moon Enceladus (5). The compounds are endogenous and we propose that they are the solid residue of crystallization of brines and entrained altered solids that reached the surface from below. The heat source may have been transient (triggered by impact heating). Alternatively, internal temperatures may be above the eutectic temperature of subsurface brines, in which case fluids may exist at depth on Ceres today.

Abstract

The Visible-Infrared Mapping Spectrometer VIR (8) on the Dawn spacecraft (9) obtained multi-spectral images of Ceres' surface in the spectral range 0.4-5 µm with an instantaneous field of view of [...], Studies of the dwarf planet (1) Ceres using ground-based and orbiting telescopes have concluded that its closest meteoritic analogues are the volatile-rich CI and CM carbonaceous chondrites (1, 2). Water in clay minerals (3), ammoniated phyllosilicates (4), or a mixture of Mg[(OH).sub.2] (brucite), [Mg.sub.2]C[O.sub.3] and iron-rich serpentine (5, 6) have all been proposed to exist on the surface. In particular, brucite has been suggested from analysis of the mid-infrared spectrum of Ceres (6). But the lack of spectral data across telluric absorption bands in the wavelength region 2.5 to 2.9 micrometres--where the OH stretching vibration and the [H.sub.2]O bending overtone are found--has precluded definitive identifications. In addition, water vapour around Ceres has recently been reported (7), possibly originating from localized sources. Here we report spectra of Ceres from 0.4 to 5 micrometres acquired at distances from ~82,000 to 4,300 kilometres from the surface. Our measurements indicate widespread ammoniated phyllosilicates across the surface, but no detectable water ice. Ammonia, accreted either as organic matter or as ice, may have reacted with phyllosilicates on Ceres during differentiation. This suggests that material from the outer Solar System was incorporated into Ceres, either during its formation at great heliocentric distance or by incorporation of material transported into the main asteroid belt.

Bibring (c) Keywords: Mars; Atmosphere; Atmosphere; Composition; Spectroscopy Abstract: We present a method to derive the 2D maps of the O.sub.2 (a.sup.1 [DELTA].sub.g) airglow emission at 1.27[mu]m from the OMEGA/MEx nadir observations. The OMEGA imaging capabilities allow monitoring the 2D distribution, daily and seasonal variation of the O.sub.2 emission intensities with a detection limit of 4 MR. The highest values, of the order of [approximately equal to]31 MR, are found on the south pole for 11h Atmospheric waves crossing the terminator on the southern polar regions are observed for the first time during the MY28 early spring. The spatial scale of the waves ranges from 100 to 130km, and the intensity fluctuations are of the order of 4MR. This study confirms the high potentiality of O.sub.2 (a.sup.1 [DELTA].sub.g) day glow as a passive tracer of the martian atmosphere dynamics at high latitudes.
