Simulation and experiment of gas diffusion in a granular bed
Carsten Güttler, Martin Rose, Holger Sierks +6
The diffusion of gas through porous material is important to understand the physical processes underlying cometary activity. We study the diffusion of a rarefied gas (Knudsen regim…
AMBITION -- Comet Nucleus Cryogenic Sample Return (White paper for ESA's Voyage 2050 programme)
D. Bockelée-Morvan, G. Filacchione, K. Altwegg +27
This white paper proposes that AMBITION, a Comet Nucleus Sample Return mission, be a cornerstone of ESA's Voyage 2050 programme. We summarise some of the most important questions s…
Centrifugal Experiments with Simulated Regolith:Effects of Gravity, Size Distribution, and Particle Shape on Porosity
Tomomi Omura, masato Kiuchi, Carsten Güttler +1
Porosity is a key characteristic of the regolith on the surface of small bodies. The porosity of the regolith on the surface of asteroids is changed by applied pressure, and the re…
Distance determination method of dust particles using Rosetta OSIRIS NAC and WAC data
E. Drolshagen, T. Ott, D. Koschny +42
The ESA Rosetta spacecraft has been tracking its target, the Jupiter-family comet 67P/Churyumov-Gerasimenko, in close vicinity for over two years. It hosts the OSIRIS instruments:…
Gravitational slopes, geomorphology, and material strengths of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
O. Groussin, L. Jorda, A. -T. Auger +49
We study the link between gravitational slopes and the surface morphology on the nucleus of comet 67P/Churyumov-Gerasimenko and provide constraints on the mechanical properties of…
Spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from the OSIRIS instrument onboard the ROSETTA spacecraft
S. Fornasier, P. H. Hasselmann, M. A. Barucci +51
The Rosetta mission of the European Space Agency has been orbiting the comet 67P/Churyumov-Gerasimenko (67P) since August 2014 and is now in its escort phase. A large complement of…
