JAXA MMX mission to collect Phobos samples for return to Earth
The Japan Aerospace Exploration Agency (JAXA) is preparing to launch the Martian Moons eXploration (MMX) mission, a first-of-its-kind endeavor to collect and return soil samples from the Martian moon Phobos. Scheduled to lift off on an H3 rocket from the Tanegashima Space Center around October 19 or 20, 2026, the mission aims to resolve long-standing scientific debates regarding the origins of Mars’ two moons, Phobos and Deimos.
Scientists are currently divided between two primary theories: that the moons are captured asteroids or that they formed from debris following a massive impact on Mars. By analyzing the chemical composition of Phobos, researchers hope to distinguish between these hypotheses. The mission includes the deployment of the Idefix rover, a joint German-French development by DLR and CNES, which is expected to land on Phobos in 2029 to conduct surface exploration.
The MMX mission is a major international collaboration involving NASA, the European Space Agency (ESA), CNES, and DLR. NASA is contributing scientific instruments, including the MEGANE and P-Sampler, as well as communication and navigation support. Following the collection of at least 10 grams of material, the mission plans to return the samples to Earth by 2031, with the sample container expected to land in Australia.
