Japan's Martian Moons eXploration mission launched from Tanegashima on Monday, carrying the Idafix rover to Phobos, with about 10 grams of material due back on Earth by 2031. Early coverage said the spacecraft would reach Mars in 2027; the latest reporting puts its arrival at Phobos next August instead. The mission's central unresolved question remains whether Phobos and Deimos are captured asteroids or debris from a Martian impact. No segment has reported a change to the sample-return timeline.
