Japan successfully launched its Martian Moons Exploration (MMX) spacecraft on an unprecedented mission to collect samples from Phobos, a small moon orbiting Mars. The unmanned probe lifted off from Tanegashima Space Centre using Japan’s H3 rocket early in the morning, with the launch declared successful approximately one hour after takeoff when the spacecraft separated from the rocket’s upper stage.
The mission represents the first attempt by any nation to land on either of Mars’s two small moons. The spacecraft is projected to reach Mars’s orbit in August next year and will collect at least 10 grams of soil and rock from Phobos’s surface before returning to Earth in 2031. The five-year mission involves collaboration among five space agencies and features a robotic rover and a stationary lander designed to operate in the extremely low-gravity environment of Phobos, which orbits Mars three times daily at a distance of approximately 6,000 kilometers above the planet’s surface.
The mission’s scientific objectives focus on determining how the two Martian moons formed. Two competing theories exist: the “giant impact” hypothesis suggests the moons resulted from a collision with Mars, while the “capture” hypothesis proposes they are asteroids pulled into orbit by Martian gravity. Scientists believe answering this question could provide insights into how habitable environments may have developed on terrestrial planets, potentially offering clues about the origins of life in the solar system.
The Japanese initiative arrives amid increased international competition regarding Mars exploration. The United States has collected samples through its Perseverance rover, though the return mission faced delays following congressional action. China’s Tianwen-3 spacecraft is scheduled for launch around 2028 and could potentially return Martian samples by 2031, possibly coinciding with or preceding the Japanese moon mission’s scheduled return.
