Revealing the interior structure of icy moons with a Bayesian approach to magnetic induction measurements
John B. Biersteker, Benjamin P. Weiss, Corey J. Cochrane +6
Some icy moons and small bodies in the solar system are believed to host subsurface liquid water oceans. The interaction of these saline, electrically conductive oceans with time-v…
The Renaissance of Main Belt Asteroid Science
Simone Marchi, Carol A. Raymond, Christopher T. Russell
The NASA Dawn spacecraft took off from Cape Canaveral in September 2007 atop a Delta II rocket starting an ambitious journey to Vesta and Ceres, the two most massive worlds in the…
The surface of (4) Vesta in visible light as seen by Dawn/VIR
B. Rousseau, M. C. De Sanctis, A. Raponi +9
We analyzed the surface of Vesta at visible wavelengths, using the data of the Visible and InfraRed mapping spectrometer (VIR) on board the Dawn spacecraft. We mapped the variation…
The brittle boulders of dwarf planet Ceres
Stefan Schröder, Uri Carsenty, Ernst Hauber +2
We mapped all boulders larger than 105 m on the surface of dwarf planet Ceres using images of the Dawn framing camera acquired in the Low Altitude Mapping Orbit (LAMO). We find tha…
Feasibility of characterizing subsurface brines on Ceres by electromagnetic sounding
Robert Grimm, Julie Castillo-Rogez, Carol Raymond +1
The ice-rich dwarf planet Ceres is the largest object in the main asteroid belt and is thought to have a brine or mud layer at a depth of tens of kilometers. Furthermore, recent su…
The surface of (1) Ceres in visible light as seen by Dawn/VIR
B. Rousseau, M. C. De Sanctis, A. Raponi +9
We study the surface of Ceres at visible wavelengths, as observed by the Visible and InfraRed mapping spectrometer (VIR) onboard the Dawn spacecraft, and analyze the variations of…
The Case for Non-Cryogenic Comet Nucleus Sample Return
Keiko Nakamura-Messenger, Alexander G. Hayes, Scott Sandford +22
Comets hold answers to mysteries of the Solar System by recording presolar history, the initial states of planet formation and prebiotic organics and volatiles to the early Earth.…
The boulder population of asteroid 4 Vesta: Size-frequency distribution and survival time
Stefan E. Schröder, Uri Carsenty, Ernst Hauber +3
Dawn's framing camera observed boulders on the surface of Vesta when the spacecraft was in its lowest orbit (LAMO). We identified, measured, and mapped boulders in LAMO images, whi…
Spectrophotometric Modeling and Mapping of Ceres
Jian-Yang Li, Stefan E. Schröder, Stefano Mottola +8
We report a comprehensive analysis of the global spectrophotometric properties of Ceres using Dawn Framing Camera images collected from April to June 2015 during the RC3 and Survey…
Ceres' opposition effect observed by the Dawn framing camera
Stefan E. Schröder, Jian-Yang Li, Marc D. Rayman +12
The surface reflectance of planetary regoliths may increase dramatically towards zero phase angle, a phenomenon known as the opposition effect (OE). Two physical processes that are…
Resolved Photometry of Vesta Reveals Physical Properties of Crater Regolith
S. E. Schröder, S. Mottola, H. U. Keller +2
During its year-long orbital mission, the Dawn spacecraft has mapped the surface of main-belt asteroid Vesta multiple times at different spatial resolutions and illumination and vi…
Resolved Spectrophotometric Properties of the Ceres Surface from Dawn Framing Camera Images
S. E. Schröder, S. Mottola, U. Carsenty +9
We present a global spectrophotometric characterization of the Ceres surface using Dawn Framing Camera (FC) images. We identify the photometric model that yields the best results f…
Spectrophotometric properties of dwarf planet Ceres from the VIR spectrometer on board the Dawn mission
M. Ciarniello, M. C. De Sanctis, E. Ammannito +14
We study the spectrophotometric properties of dwarf planet Ceres in the VIS-IR spectral range by means of hyper-spectral images acquired by the VIR imaging spectrometer on board th…
Surface Albedo and Spectral Variability of Ceres
Jian-Yang Li, Vishnu Reddy, Andreas Nathues +21
Previous observations suggested that Ceres has active but possibly sporadic water outgassing, and possibly varying spectral characteristics in a time scale of months. We used all a…
Constraining the Cratering Chronology of Vesta
David P. O'Brien, Simone Marchi, Alessandro Morbidelli +4
Vesta has a complex cratering history, with ancient terrains as well as recent large impacts that have led to regional resurfacing. Crater counts can help constrain the relative ag…
Global Photometric Properties of Asteroid (4) Vesta Observed with Dawn Framing Camera
Jian-Yang Li, Lucille Le Corre, Stefan E. Schröder +9
Dawn spacecraft orbited Vesta for more than one year and collected a huge volume of multispectral, high-resolution data in the visible wavelengths with the Framing Camera. We prese…
Olivine or Impact Melt: Nature of the "Orange" Material on Vesta from Dawn
Lucille Le Corre, Vishnu Reddy, Nico Schmedemann +18
NASA's Dawn mission observed a great variety of colored terrains on asteroid (4) Vesta during its survey with the Framing Camera (FC). Here we present a detailed study of the orang…
Comparing Dawn, Hubble Space Telescope, and Ground-Based Interpretations of (4) Vesta
Vishnu Reddy, Jian-Yang Li, Lucille Le Corre +10
Observations of asteroid 4 Vesta by NASA's Dawn spacecraft are interesting because its surface has the largest range of albedo, color and composition of any other asteroid visited…
Small crater populations on Vesta
S. Marchi, W. F. Bottke, D. P. O'Brien +7
The NASA Dawn mission has extensively examined the surface of asteroid Vesta, the second most massive body in the main belt. The high quality of the gathered data provides us with…
