GoKawiilJAXA sets October 2026 launch for MMX mission to land on Phobos and return samples
Japan's space agency JAXA plans to launch its Martian Moons eXploration (MMX) spacecraft on October 20, 2026, aiming to collect at least 10 grams of material from Phobos, one of Mars' two moons. The mission, built by Mitsubishi Electric, would take about a year to reach Mars, spend three years studying the planet and its moons, then return samples to Earth by 2031.
GoKawiil's interpretation of the reporting above, not reported fact.
No mission has ever retrieved samples from a body orbiting Mars, so a successful touchdown would give scientists fresh insight into whether Phobos formed from a captured asteroid or debris from a Mars impact. The landing itself is a major technical hurdle since Phobos' gravity sits awkwardly between that of asteroids and the Moon, forcing the spacecraft to navigate and decide on landing safety autonomously due to communication delays of up to 20 minutes.
- MMX launches October 20, 2026, targeting a 2031 sample return to Earth.
- Phobos' unusual gravity level rules out landing methods used on asteroids or the Moon.
- The spacecraft must autonomously assess terrain and abort unsafe landings due to long communication delays.
