MMX Mission Takes Off from Japan
On October 20, 2023, Japan's space agency JAXA successfully initiated the MMX mission, targeting Mars' moon Phobos for in-depth exploration. The H3 launch vehicle lifted off from the Tanegashima Space Center, deploying the 5-ton Martian Moons Exploration (MMX) spacecraft into orbit. The mission's primary objective is to land on Phobos, collect surface samples, and deliver them back to Earth by 2031.
Global Partnership and Advanced Technologies
This ambitious project involves collaboration between Japan, the United States, France, Germany, and the European Space Agency, with a combined budget of $578 million. To assist in the surface exploration, French and German engineers developed a compact four-wheeled rover named Idefix, roughly the size of a microwave oven. Idefix is designed to operate on Phobos for approximately 100 days, moving at a slow pace of about 1 millimeter per second.
The journey to Mars’ system will take around one year, after which MMX will spend three years orbiting and studying Phobos and Deimos, Mars’ two moons measuring roughly 20 km and 10 km in diameter, respectively. The mission's critical phase includes landing first the Idefix rover, followed by the main MMX lander. MMX will remain on Phobos' surface for about two hours to collect roughly 10 grams of regolith samples.
Previous attempts by the Soviet Union and Russia to land on Phobos were unsuccessful despite three missions. The closest achievement was by the Phobos-2 spacecraft in 1989, which managed to approach the moon and transmit photographs. MMX aims to build on these earlier efforts and significantly advance our understanding of Mars' moons.

Successful completion of this mission is expected to yield valuable insights into the origin and development of Phobos and Mars itself, shedding light on the conditions necessary for life beyond Earth. Studying these moons also paves the way for future space endeavors, including potential colonization and resource utilization in the Martian system.
As Japan embarks on its ambitious MMX mission to explore Phobos, the UAE is also making strides in space exploration with its own eight-year journey to the asteroid belt. This mission, set to conclude with a landing on asteroid 269 Justitia in 2036, showcases the growing global commitment to uncovering the mysteries of our solar system.
