Meet the people behind MMX
Led by JAXA, MMX is Japan's largest space exploration mission, taking on the challenge of returning samples from a Martian moon. Building on the technology for landing and sampling small celestial bodies developed with the asteroid exploration missions, Hayabusa and Hayabusa2, JAXA is working alongside international space agencies, industry partners, and the scientific community to make the mission a success.

MMX Partnerships
MMX has established international partnership agreements with the National Aeronautics and Space Administration (NASA), the French Centre National d'Etudes Spatiales (CNES), the German Aerospace Center (DLR), and the European Space Agency (ESA). These agreements create a cooperative framework for enabling close collaboration across key mission areas, including the provision of onboard equipment, deep-space communication support, and ground station operations.

Science Board
At MMX, we work closely with the scientific community in Japan and around the world through the establishment of our Science Strategy Team and seven Working Teams (WT). These teams lead mission operation studies, and to conduct continuous reviews to ensure that the scientific objectives of the MMX mission are fully realised.

Science Strategy Team (SST)
Origin of Phobos and Deimos Science Strategy Team
This team develops an integrated science strategy combining remote-sensing observations and returned-sample analyses to reveal the origin of the Martian moons, Phobos and Deimos. (Team Leader: Nakamura Tomoki)
Early Solar System Evolution Science Strategy Team
This team develops the science strategy for utilising the returned Phobos samples and other MMX data for investigating planet formation and the evolution and transport of primitive materials in the early Solar System. (Team Leader: Genda Hidenori)
Surface Science and Geology Science Strategy Team
This team develops the science strategy for investigating the morphology, geology, and surface properties of Phobos and Deimos to understand how their surfaces formed and evolved. (Team Leader: Miyamoto Hideaki)
Mars System Science Strategy Team
This team develops the science strategy for investigating the Martian atmosphere, surface, and material exchange with its moons to better understand the evolution of the Mars system. (Team Leader: Imamura Takeshi)
Geodesy Science Strategy Team
This team develops the geodetic strategy for precisely determining the shapes, gravity fields, rotations, and spacecraft orbits of the Martian moons, supporting studies of their interiors, science observations, and landing-site selection. (Team Leader: Matsumoto Koji)
