Story summary

Japan launched its MMX spacecraft on Tuesday aboard a new Japanese mainstay H-3 rocket, marking the start of a five-year mission to bring back samples from Phobos, one of Mars' moons. This is the world's first round-trip mission to a Martian moon and aims to provide insights into how Phobos formed and whether it could serve as a base for future human missions to Mars. The Japan Aerospace Exploration Agency (JAXA) collaborated with NASA, ESA, French, and German institutions on this project, which includes a rover named IDEFIX that will collect at least 10 grams of material from Phobos's surface.
