# Japan Launches MMX Mission to Retrieve Martian Moon Samples A multi-agency spacecraft embarks on a complex journey to Phobos for soil collection. - **Source:** [ABC News: Technology](http://abcnews.com) - **Published:** 2026-10-20 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/a9712d80-fdb6-4b08-94d9-02a2fbc6f967 ## Ambitious Martian Moon Mission The Japan Aerospace Exploration Agency successfully launched the MMX spacecraft from Tanegashima Island. This five-year mission aims to explore Mars' moons, Phobos and Deimos, marking a significant step in space exploration. The project involves a collaborative effort between five international space agencies, targeting a historic sample return to Earth by 2031. ## Technical Mission Specifications The $578 million MMX mission features a 5-ton spacecraft designed to reach Mars by late next summer. The project is backed by a $350 million Japanese investment, with additional funding from NASA, French, German, and European space agencies. The spacecraft will sync with Phobos' orbit before deploying a specialized robotic rover. ## Idefix Rover Deployment Strategy The French-German rover, Idefix, is a microwave-sized vehicle designed to navigate the low-gravity environment of Phobos. It will move at a slow pace of 1 millimeter per second for 100 days. Its primary role is to act as a scout, identifying safe terrain for the mothership to land and collect samples. ## Sample Collection and Return The stationary lander will spend two hours on the surface of Phobos, drilling and vacuuming at least 10 grams of material. Following the collection, the spacecraft will conduct flybys of Deimos before departing the Martian system in 2030. The samples are scheduled to arrive in the Australian desert during 2031. ## Scientific Objectives and Origins Researchers aim to determine if Phobos and Deimos formed from an ancient collision between Mars and a space rock or if they are captured asteroids. Analyzing these samples could reveal traces of Mars, providing insights into planetary formation and the potential history of life within the Martian system for future missions. ## Global Competitive Landscape Japan faces competition in the race to retrieve Martian samples, with China planning a similar mission by 2028. Meanwhile, NASA continues to deliberate on strategies to retrieve sample tubes collected by the Perseverance rover. Both Japan and China are currently targeting the year 2031 for their respective sample return milestones. ## Historical Context of Challenges Landing on Phobos remains an unprecedented challenge, as no agency has successfully reached or sampled these moons. Russia previously attempted three missions to Phobos without success, and Japan experienced a prior failure in orbiting Mars. These past difficulties underscore the technical complexity and high risk associated with this current exploration effort. ## Future Implications for Exploration The success of the MMX mission will provide critical data for future human-led Mars exploration. By demystifying the composition of Martian moons, scientists hope to establish a clearer understanding of the solar system's evolution. This mission represents a once-in-a-lifetime opportunity to gather material that could reshape our knowledge of planetary science. ## Sources covering this story - https://abcnews.com/Technology/wireStory/japan-launches-spacecraft-mysterious-moons-mars-bold-mission-137391500 — --- _Summary written by Brifing from the original reporting.
