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 is divided among the seven payloads as follows: In 2022, a robotic rover was proposed to be launched to Mars in order to scout a landing site for the 2027 lander and a site for the Mars One colony. At the same time, a communication satellite would be launched, enabling continuous communication with the future landed assets. In 2024, six cargo missions were proposed to be in close succession, consisting of two living units, two life-support units, and two supply units. A spacecraft transporting four astronauts was proposed to meet a transit vehicle bound for Mars. In 2025, the landing
