  "account": "Japanese scientists are preparing an unprecedented mission to Mars's moons, aiming to retrieve samples that may unlock the origins of the Solar System and life on Earth. The unmanned Martian Moons eXploration (MMX) probe, a collaboration involving US, European, and numerous other international partners, could also pave the way for future human exploration of the Red Planet. The flagship H3 rocket, carrying the MMX spacecraft, is scheduled to depart from the Tanegashima Space Center on Tuesday at 4:41 am (1941 GMT Monday).\n\nUpon reaching Mars one year later, the spacecraft will orbit the moon Phobos for up to three years before landing to collect at least 10 grams of material from its surface. A rover named IDEFIX will first conduct surface observations to ensure a safe landing. This mission marks the first round trip to the Martian system, as well as the first time samples will be collected from Phobos, the smaller of Mars's two moons.\n\nIn addition to its primary objective, the MMX mission will also explore the possibility of using Phobos as a \"natural space station\" to establish the requirements for a round trip to Mars—a crucial step in preparing for crewed Mars exploration. The probe will also observe Mars's other moon, Deimos, although it will not land on it. Upon returning to Earth, the gathered samples will provide invaluable insights into the formation of Mars and its moons, potentially shedding light on how life might have emerged on terrestrial planets.\n\nThe MMX mission is a collaborative effort between Japan's space agency, France's National Centre for Space Studies (CNES), Germany's Aerospace Center (DLR), NASA, the European Space Agency (ESA), and around 20 universities and tech companies. One of the most challenging aspects of the mission is developing the spacecraft's landing legs, as Phobos has extremely weak gravity. JAXA scientists have noted that Japan has experience in bringing back samples from space, including its successful Hayabusa-2 mission, which returned asteroid samples in 2020. However, MMX faces a unique challenge—traveling deep into the \"gravity well\" of Mars to return to Earth, a feat that will require escaping the planet's strong gravitational pull.",
