Summary

This documentary from the series ‘Les Dossiers de l’Espace’ presents the Japanese space mission MMX (Martian Moons eXploration), which aims to return samples from Phobos, the largest moon of Mars. The video explains the scientific questions surrounding the origin of Phobos and Deimos, detailing the two main hypotheses: captured asteroids or remnants of a giant impact on Mars. It then describes the mission architecture, including the spacecraft’s journey, its instruments, and the challenging landing and sampling procedure on Phobos. The video highlights the collaboration with CNES and DLR for a small rover that will explore the surface and test technologies for low-gravity mobility. It also discusses the potential for future human exploration of the Martian moons, as they could serve as a stepping stone for deeper space exploration. The documentary emphasizes the scientific value of the samples, which could provide insights into the history of water in the inner solar system. It concludes by placing MMX in the broader context of Mars exploration, with other sample return missions planned by NASA and CNSA.
