MMX
To be launched in September 2024 and inserted into Martian orbit in 2025, the Martian Moons eXploration mission (MMX) is a JAXA mission to Phobos and Deimos investigating the origin of the two Martian moons. While surface spectra indicate an origin from captured asteroids, the moons’ orbits favour formation scenarios involving the ejecta from a major impact early in Martian history.
