Story summary

Japan launched the MMX probe on October 20, 2026, from Tanegashima Island, starting a five-year mission to collect samples from Mars's moon Phobos. The Japan Aerospace Exploration Agency (JAXA) is leading this international effort, which includes contributions from NASA ($122 million), the French Space Agency ($95 million), the German Space Agency ($79 million), and the European Space Agency ($24 million). This mission aims to study Phobos' origins and formation, as well as provide insights into Mars's history. No previous mission has successfully brought samples back from Phobos or its companion Deimos. If successful, samples will return to Earth in 2031.
