[P-PS05] Mars

Thu. May 28, 2015 9:00 AM - 10:45 AM A03 (APA HOTEL&RESORT TOKYO BAY MAKUHARI)

Convener:*Takehiko Satoh(Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Masaki Ishiwatari(Department of Cosmosciences, Graduate school of Science, Hokkaido University), Sho Sasaki(Department of Earth and Space Sciences, School of Science, Osaka University), Yoshiyuki O. Takahashi(Graduate School of Science, Kobe University), Ayako Matsuoka(Research Division for Space Plasma, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency), Hideaki Miyamoto(The University Museum, The University of Tokyo), Chair:Yoshiyuki O. Takahashi(Graduate School of Science, Kobe University)

The study on Mars has greatly been advanced due to new data from modern missions as well as to new results from theoretical and numerical works. Morphology and variable phenomena, seen on the surface, in the atmosphere and its surrounding plasma, all indicate that Mars is still an active planet. After successful arrivals of American and Indian orbiters in 2014, Mars is now being investigated by 5 orbiters and 2 rovers, the largest ever number.
In Japan, on the other hand, possibilities of small planetary missions are becoming more realistic (Mars is the most important target object, of course) and the roadmap of solar system exploration is under development. In this session, current researches on Mars, including the latest results from missions, as well as future mission plans are discussed.
