(1) "The International Phobos/Deimos Data Working Group and its support of MMX"
Thomas C. Duxbury
Department of Physics and Astronomy George Mason University, USA
We overview the activity of the International Phobos/Deimos Data Working Group (PDDWG). One of its main objectives is for producing a priority listing of existing data needed to support MMX sample site selection and proximity operations. The highest priority data included those from Mars Express HRSC and OMEGA, Viking Orbiter imaging, PHOBOS 88 imaging, and MAVEN IUVS. They will provide information on the moon ephemerides, orientations, topographies and gravity for proximity operations of MMX, and provide information on surface composition, minerology, slopes, local force fields and hazards for sample site selection of MMX.
(2) "The formation of the Martian moons: observations and modeling"
University of Nice, France
A giant collision is widely accepted to explain the formation of the moon of the Earth. The origin of the Martian moons is a question still largely open. Two main formation scenarios have been proposed so far: capture vs in-situ. In this lecture we will review the modeling efforts with regard to the Phobos sample return opportunity of the Martian Moon Exploration mission of the Japanese space agency (JAXA).
