Deimos and Phobos Interior Explorer that the moons of Mars may have formed after a huge collision with a protoplanet one third the mass of Mars that formed a ring around Mars. A third hypothesis is that they may have co-accreted with the parent planet. DePhine mission would explore the origin and the evolution of the two Martian satellites, by focusing on their interior structures and diversity. The mission would attempt to determine if Phobos and Deimos true siblings, originating from the same source and sharing the same formation scenario. It would also determine if both natural satellites are rubble piles or solid bodies, and
Mars One men and 50 women from the total pool of 660 from around the world were selected to move on to the third round of the astronaut selection process: Applicants were remotely interviewed and recorded by Mars One over a relatively short Skype/SparkHire call regarding Martian-related orbital, temp/pressure, geological and historical parameters and the specific elements of the Mars One one-way mission. Joseph Roche, one of the finalists, has accused the selection process of being based on a point system that is primarily dependent on how much money each individual generated or gave to the Mars One organization, despite many of
