Microporosity and parent body of the rubble-pile NEA (162173) Ryugu
Wladimir Neumann, Matthias Grott, Mario Trieloff +4
Observations of C-type NEAs and lab investigations of carbonaceous chondritic (CC) meteorites provide strong evidence for a high porosity of C-type asteroids. Boulder microporosity…
Characterization of the MASCOT landing area by Hayabusa2
Stefan Schröder, Naoya Sakatani, Rie Honda +26
Context. After landing on C-type asteroid Ryugu, MASCOT imaged brightly colored, submillimeter-sized inclusions in a small rock. Hayabusa2 successfully returned a sample of small p…
Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
An Extremely Elongated Cloud over Arsia Mons Volcano on Mars: I. Life Cycle
J. Hernández-Bernal, A. Sánchez-Lavega, T. del Río-Gaztelurrutia +12
We report a previously unnoticed annually repeating phenomenon consisting of the daily formation of an extremely elongated cloud extending as far as 1800 km westward from Arsia Mon…
Spectrophotometric analysis of the Ryugu rock seen by MASCOT: Searching for a carbonaceous chondrite analog
Stefan Schröder, Katharina Otto, Hannah Scharf +11
We analyze images of a rock on Ryugu acquired in situ by MASCam, camera of the MASCOT lander, with the aim of identifying possible carbonaceous chondrite (CC) analogs. The rock's r…
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…
Close-up images of the final Philae landing site on comet 67P/Churyumov-Gerasimenko acquired by the ROLIS camera
S. E. Schröder, S. Mottola, G. Arnold +11
After coming to rest on the night side of comet 67P/Churyumov-Gerasimenko, the ROLIS camera on-board Rosetta's Philae lander acquired five images of the surface below the lander, f…
The global surface composition of 67P/CG nucleus by Rosetta/VIRTIS. I) Prelanding mission phase
Gianrico Filacchione, Fabrizio Capaccioni, Mauro Ciarniello +27
From August to November 2014 the Rosetta orbiter has performed an extensive observation campaign aimed at the characterization of 67P/CG nucleus properties and to the selection of…
Saturn's icy satellites investigated by Cassini - VIMS. IV. Daytime temperature maps
Gianrico Filacchione, Emiliano D'Aversa, Fabrizio Capaccioni +13
The spectral position of the 3.6 micron continuum peak measured on Cassini-VIMS I/F spectra is used as a marker to infer the temperature of the regolith particles covering the surf…
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…
Back to the Moon: The Scientific Rationale for Resuming Lunar Surface Exploration
I. A. Crawford, M. Anand, C. S. Cockell +4
The lunar geological record has much to tell us about the earliest history of the Solar System, the origin and evolution of the Earth-Moon system, the geological evolution of rocky…
