JapanMission launched; sample return targeted for 2031
Japan launches the first mission designed to return samples from a moon of Mars
Japan launched its MMX spacecraft from Tanegashima early Tuesday local time, beginning a mission to study Phobos and Deimos and bring material from Phobos back to Earth. The international project is led by JAXA with instruments and support from NASA and European partners; if the mission proceeds as planned, samples will return in 2031.
Why Americans should know: NASA supplied key instruments and U.S. scientists will help analyze the samples. The mission could clarify how Mars's moons formed and inform future robotic and crewed exploration.
