Japan’s MMX Mission Aims to Return First Samples from Martian Moon Phobos

TEHRAN, Oct 19 (OPA) — The Japan Aerospace Exploration Agency (JAXA) has finalized plans for its MMX mission, which seeks to land on Phobos, the larger of Mars’ two moons. The spacecraft will collect approximately 10 grams of surface material before conducting a flyby of the smaller moon, Deimos, and beginning its return journey to Earth.

Projected to land in a remote region of Australia in 2031, the mission aims to resolve long-standing questions regarding the origin of the Martian moons. Scientists currently debate whether Phobos and Deimos are captured asteroids or remnants of a massive impact event that occurred on the Martian surface.

Beyond the moons themselves, researchers anticipate the samples may contain debris ejected from Mars during past celestial collisions. Analyzing these particles in a laboratory setting could provide unprecedented data regarding the chemical composition of the Martian surface and the planet’s geological history.

If successful, the MMX mission will mark the first time samples from Phobos have been returned to Earth. This achievement would provide a new pathway for studying Martian-related materials without the immediate logistical constraints of a direct landing on the planet’s surface.
