JAXA Launches MMX Mission to Retrieve Soil Samples from Mars Moon Phobos

Japan Aerospace Exploration Agency (JAXA) has successfully launched the Martian Moons eXploration (MMX) spacecraft using its flagship H3 launch vehicle from the Tanegashima Space Center. The five-year mission aims to achieve a world-first sample return from Phobos, one of the moons of Mars.
What happened
The Japan Aerospace Exploration Agency (JAXA) launched the Martian Moons eXploration (MMX) spacecraft using an H3 launch vehicle from the Yoshinobu Launch Complex at the Tanegashima Space Center in southwestern Japan. Following liftoff, the spacecraft successfully confirmed separation from the launch vehicle's upper stage and completed its initial critical operations phase.
The primary objective of the five-year mission is to achieve a world-first sample return from Phobos, collecting at least 10 grams of surface material or regolith. The spacecraft carries the French-German rover 'Idefix', developed jointly by CNES and DLR, which will land on Phobos to study surface properties and assist in identifying sample collection sites. Additionally, the MMX mission will perform orbital surveys of both Martian moons, Phobos and Deimos, and monitor the Martian atmosphere to help determine whether the moons are captured asteroids or the result of debris from a collision with Mars.
