Deimos and Phobos Interior Explorer Center (DLR) and a study team with representatives of the scientific community and the space industry. The mission would explore the origin and the evolution of the two Martian moons, and would also contribute to the general questions of planetary formation and the workings of the Solar System. The origin of the Martian moons is controversial. Phobos and Deimos both have much in common with carbonaceous C-type asteroids, with spectra, albedo, and density very similar to those of C- or D-type asteroids. Based on their similarity, one hypothesis is that both moons may be captured main-belt asteroids. Another hypothesis is
Mars One but that accommodating Mars One requirements would require some additional work and that such action was not a part of the current focus of SpaceX. SpaceX has no ongoing contracts with Mars One. The first Mars One cargo mission to Mars is proposed to launch by 2022, followed by a crewed mission in 2024, but without funds, hardware, and without a launcher it is seen as unlikely to happen. A hypothetical crewed interplanetary spacecraft, for which there are no concept design studies, would be assembled in low Earth orbit and comprise two propellant modules: a Transit Living Module (discarded just
