COSIMA Team POSTER LOCATION #207 Physical Properties of Dust Particles Collected by the COSIMA Instrument on Board ROSETTA [#2166] Presentation of different physical properties (size distribution, typology) of cometary grains collected by the COSIMA instrument onboard the Rosetta spacecraft.
Clark C. S. Clark P. E. POSTER LOCATION #208 Constant-Scale Natural Boundary Mapping to Depict Material Transport on Comet 67P/Churyumov-Gerasimenko [#2367] Constant-scale natural boundary mapping transforms the surface of any globular object to a two-dimensional plane in a way that preserves proportion and adjacency of natural districts composing the object’s surface.
Springmann A. Harris W. M. Howell E. S. Lovell A. J. Kikwaya Eluo J. B. et al. POSTER LOCATION #209 Narrowband Optical Observations of the Near-Nucleus Region of Jupiter-Family Comets Comet 45P/Honda-Mrkos-Pajdušáková (HMP) [#2574] Comets pass by Earth / Showing coma volatiles / And activity.
Sekhar A. Asher D. J. Werner S. C. Vaubaillon J. Li G. POSTER LOCATION #210 Change in General Relativistic Precession Rates Due to Lidov-Kozai Oscillations in the Solar System [#1876] We look at scenarios where sungrazing/suncolliding phases, induced by Kozai mechanism, can lead to rapid changes in GR precession rates in solar system bodies.

Sears D. W. G. POSTER LOCATION #215 Itokawa is a Regolith Breccia, Not a Rubble Pile [#2463] Small size/density, no rubble piles, and regolith thickness among the explored asteroids work on spin and coherence and show that Itokawa is a regolith breccia.
