New Ceres Images Show Bright Craters 19 April 2016 New Ceres images show bright craters 19 April 2016 shows rays of bluish ejected material. The color blue in such views has been associated with young features on Ceres. "Haulani perfectly displays the properties we would expect from a fresh impact into the surface of Ceres. The crater floor is largely free of impacts, and it contrasts sharply in color from older parts of the surface," said Martin Hoffmann, co-investigator on the Dawn framing camera team, based at the Max Planck Institute for Solar System Research, Göttingen, Germany. The crater's polygonal nature (meaning it resembles a shape made of straight lines) is noteworthy because most craters seen on other planetary bodies, including Earth, are nearly circular. The straight edges of some Cerean Ceres' Haulani Crater, with a diameter of 21 miles (34 craters, including Haulani, result from pre-existing kilometers), shows evidence of landslides from its crater stress patterns and faults beneath the surface. rim.

WA; 7Goddard MD; 8PSI AZ; 9JPL CA; 10LPI TX Introduction: When Dawn arrived at Ceres in 2015 it found a unique and perplexing ice-rock dwarf planet [1]. As anticipated, the overall surface is very dark, but small local areas exhibit unexpectedly bright materials that are likely indigenous in origin [2]. Near-infrared spectroscopic analyses identified the presence of am- moniated phyllosilicates (which are typically associated with the outer solar system) [3], and these were shown to be present everywhere across the surface although their relative abundance varies regionally [4]. The sur- face is heavily cratered, except for the largest craters [5], allowing relative ages to be derived [6]. The most recent craters often exhibit rays as well as local spectral properties that are relatively blue (440-960 nm) com- pared to their surroundings [2, 7]. Fresh craters that ex- hibit regular but distinct optical properties compared to similar but older areas is a characteristic indication that some form of alteration, or space weathering, occurs with time across the surface that transforms freshly ex- posed material into background soils.

Introduction: After studying the asteroid Vesta between 2011 and 2012 [1], NASA’s Dawn spacecraft entered its orbit around the dwarf planet (1) Ceres in April 2015 [2]. The mission goal is to characterize the geology, elemental and mineralogical composition, topography, shape, and internal structure of Ceres [3]. Ceres´ surface is affected by numerous impact cra- ters and some of them show features such as channels or multiple flow events forming a smooth, less cratered surface, indicating possible post-impact resurfacing [4,5]. Data: For the analysis of channels and flow fea- tures Dawn Framing Camera (FC) data (monochrome and color ratio images) [6] from the High Altitude Mapping Orbit (HAMO) with a spatial resolution of 140 m/px as well as a Digital Terrain Model (DTM) [7] derived from HAMO orbit data have enabled an initial characterization of the surface. At the time of this writing LAMO images (35 m/pixel) are just be- coming available.

Thursday, March 31, 2016 1 9:30-10:30AM Our Solar System Historical Archive: The Asteroids • If we want to understand the nature of the building blocks of the solar system we have to turn to the asteroids • The larger planets are too evolved to retain much information on the nature of the starting material. • The asteroids and the samples they send to us, the meteorites, have retained much information on the geochemistry of the early days of the solar system 2 In the Beginning • Over 4.5 billion years ago in a cloud of cold gas and dust, the solar nebula was believed to have formed and to begin accreting protoplanets. • It is also believed that a supernova occurred nearby and seeded the solar nebula with short-lived radionuclides such as 26Al, and 56Fe. • Protoplanets accreting at the time trapped the heat inside, which led to melting and differentiation. • Bodies farther out from the protosun are thought to have begun accreting later when there was less primordial heat from the radionuclides. 3 Asteroid Belt Evolution Paradigm • Vesta was formed with trapped radionuclides that helped melt the rock and drive off the primordial water. Ceres was formed later, farther from the Sun. The radioactivity had largely decayed by this time. • When Jupiter formed, the main belt was stirred by its passage around the outer edge of the belt. This changed the asteroid belt from a region of accretion to comminution.

Schröder 1 , Olivier Poch 2, Marco Ferrari 3, Simone De Angelis3, Robin Sultana2, Sandra M. Potin2, Pierre Beck2, Maria Cristina De Sanctis 3 & Bernard Schmitt 2 The Dawn mission found that the dominant colour variation on the surface of dwarf planet Ceres is a change of the visible spectral slope, where fresh impact craters are surrounded by 1234567890():,; blue (negative spectral-sloped) ejecta. The origin of this colour variation is still a mystery. Here we investigate a scenario in which an impact mixes the phyllosilicates present on the surface of Ceres with the water ice just below. In our experiment, Ceres analogue material is suspended in liquid water to create intimately mixed ice particles, which are sublimated under conditions approximating those on Ceres. The sublimation residue has a highly porous, foam-like structure made of phyllosilicates that scattered light in similar blue fashion as the Ceres surface. Our experiment provides a mechanism for the blue colour of fresh craters that can naturally emerge from the Ceres environment. 1 Deutsches Zentrum für Luft- und Raumfahrt (DLR), Berlin 12489, Germany. 2 University Grenoble Alpes, CNRS, Institut de Planétologie et d’Astrophysique ✉ de Grenoble (IPAG), Grenoble 38000, France. 3 Istituto di Astrofisica e Planetologia Spaziali-INAF, Rome 00133, Italy. email: [email protected] NATURE COMMUNICATIONS | (2021) 12:274 | https://doi.org/10.1038/s41467-020-20494-5 | www.nature.com/naturecommunications 1 ARTICLE NATURE COMMUNICATIONS | https://doi.org/10.1038/s41467-020-20494-5 hen Dawn arrived at dwarf planet (1) Ceres, it quickly like montmorillonite are mixed with liquid water, hydration of Wbecame clear that the dominant colour variation over the inter-layer space will lead to partial delamination, resulting in the surface is a variation of the spectral slope from the suspended nano-sized platelets and aggregates thereof.
