Moons of Mars formed a large moon. Gravitational interactions between this moon and the outer ring formed Phobos and Deimos. Later, the large moon crashed into Mars, but the two small moons remained in orbit. This theory agrees with the fine-grained surface of the moons and their high porosity. The outer disk would create fine-grained material. While many Martian probes provided images and other data about Phobos and Deimos, only few were dedicated to these satellites and intended to perform a flyby or landing on the surface. Two probes under the Soviet Phobos program were successfully launched in 1988, but neither conducted the
Mars One Richard Garriott stated in response to Mars One, "Many have interesting viable starting plans. Few raise the money to be able to pull it off." Former astronaut Buzz Aldrin said in an interview that he wants to see humans on Mars by 2035, but he does not think Mars One will be the first to achieve it. "Wired" magazine gave it a plausibility score of 2 out of 10 as part of their 2012 Most Audacious Private Space Exploration Plans. The project lacks current funding as well as sources for future funding. The organization has no spacecraft or rocket in
