The Asteroid Framing Cameras on ESA's Hera mission
Jean-Baptiste Vincent, Gábor Kovács, Balázs V. Nagy +7
As the first asteroid deflection test, NASA's successfully hit asteroid Dimorphos (secondary of the binary asteroid 65803 Didymos) with the DART kinetic impactor on September 26, 2…
A Contact Binary Satellite of the Asteroid (152830) Dinkinesh
Harold F. Levison, Simone Marchi, Keith S. Noll +3
Asteroids with diameters less than about 5 km have complex histories because they are small enough for radiative torques, YORP, to be a notable factor in their evolution. (152830)…
Constraining models of activity on comet 67P/Churyumov-Gerasimenko with Rosetta trajectory, rotation, and water production measurements
Nicholas Attree, Laurent Jorda, Olivier Groussin +11
Aims. We use four observational data sets, mainly from the Rosetta mission, to constrain the activity pattern of the nucleus of comet 67P/Churyumov-Gerasimenko. Methods. We develop…
ROSETTA/OSIRIS observations of the 67P nucleus during the April 2016 flyby: high-resolution spectrophotometry
C. Feller, S. Fornasier, S. Ferrari +35
In April 2016, the Rosetta spacecraft performed a low-altitude low-phase-angle flyby over the Imhotep-Khepry transition of 67P/Churyumov-Gerasimenko's nucleus. The OSIRIS/Narrow-An…
Tensile Strength of 67P/Churyumov-Gerasimenko Nucleus Material from Overhangs
N. Attree, O. Groussin, L. Jorda +52
We directly measure twenty overhanging cliffs on the surface of comet 67P/Churyumov-Gerasimenko extracted from the latest shape model and estimate the minimum tensile strengths nee…
Thermal fracturing on comets. Applications to 67P/Churyumov-Gerasimenko
N. Attree, O. Groussin, L. Jorda +12
We simulate the stresses induced by temperature changes in a putative hard layer near the surface of comet 67P/Churyumov--Gerasimenko with a thermo-viscoelastic model. Such a layer…
The reference frames of Mercury after MESSENGER
Alexander Stark, Jürgen Oberst, Frank Preusker +3
We report on recent refinements and the current status for the rotational state models and the reference frame of the planet Mercury. We summarize the performed measurements of Mer…
Constraints on cometary surface evolution derived from a statistical analysis of 67P's topography
J. -B. Vincent, S. F. Hviid, S. Mottola +51
We present a statistical analysis of the distribution of large scale topographic features on comet 67P/Churyumov-Gerasimenko. We observe that the cumulative cliff height distributi…
Seasonal Mass Transfer on the Nucleus of Comet 67P/Chuyumov-Gerasimenko
H. U. Keller, S. Mottola, S. F. Hviid +47
We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes stro…
Modeling of the outburst on July 29th, 2015 observed with OSIRIS cameras in the southern hemisphere of comet 67P/Churyumov-Gerasimenko
A. Gicquel, M. Rose, J. -B. Vincent +60
Images of the nucleus and the coma (gas and dust) of comet 67P/Churyumov- Gerasimenko have been acquired by the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System)…
Variegation and space weathering on asteroid 21 Lutetia
S. E. Schröder, H. U. Keller, S. Mottola +4
During the flyby in 2010, the OSIRIS camera on-board Rosetta acquired hundreds of high-resolution images of asteroid Lutetia's surface through a range of narrow-band filters. While…
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…
Decimetre-scaled spectrophotometric properties of the nucleus of comet 67P/Churyumov-Gerasimenko from OSIRIS observations
C. Feller, S. Fornasier, P. H. Hasselmann +43
We present the results of the photometric and spectrophotometric properties of the 67P/Churyumov-Gerasimenko nucleus derived with the OSIRIS instrument during the closest fly-by ov…
Summer fireworks on comet 67P
J. -B. Vincent, M. F. A'Hearn, Z. -Y. Lin +52
During its two years mission around comet 67P/Churyumov-Gerasimenko, ESA's Rosetta spacecraft had the unique opportunity to follow closely a comet in the most active part of its or…
Sublimation of icy aggregates in the coma of comet 67P/Churyumov-Gerasimenko detected with the OSIRIS cameras onboard Rosetta
A. Gicquel, J. -B. Vincent, J. Agarwal +58
Beginning in March 2014, the OSIRIS (Optical, Spectroscopic, and Infrared Remote Imaging System) cameras began capturing images of the nucleus and coma (gas and dust) of comet 67P/…
Towards High-Resolution Mercury Global Topography from MESSENGER Orbital Stereo Imaging - A Prototype Model for the H6 Quadrangle "Kuiper"
Frank Preusker, Alexander Stark, Jürgen Oberst +3
We selected approximately 10,500 Narrow Angle Camera (NAC) and Wide-Angle Camera (WAC) stereo images obtained by the MESSENGER spacecraft during its orbital mission with average re…
Are fractured cliffs the source of cometary dust jets ? Insights from OSIRIS/Rosetta at 67P
J. -B. Vincent, N. Oklay, M. Pajola +52
Dust jets, i.e. fuzzy collimated streams of cometary material arising from the nucleus, have been observed in-situ on all comets since the Giotto mission flew by comet 1P/Halley in…
