Led by the Japan Aerospace Exploration Agency (JAXA), the MMX mission aims to reach the Martian moon Phobos to collect at least 10 grams of surface material and return it to Earth for scientific analysis. Scientists hope these samples will shed light on the origin of Mars's two moons and deepen our understanding of the solar system's early stages.
The uncrewed spacecraft, which launched aboard an H3 rocket from the Tanegashima Space Center, is expected to reach Mars in August 2027 and successfully return the collected samples back to Earth in 2031.
The launch marked the very first interplanetary mission for Japan's flagship H3 rocket. This follows the rocket's high-profile failure on its inaugural flight in 2023, when its second-stage engine failed to ignite before it completed subsequent successful flights.
