Mars mainly phyllosilicates and other minerals known from Mars, point toward an origin of Phobos from material ejected by an impact on Mars that reaccreted in Martian orbit, similar to the prevailing theory for the origin of Earth's moon. Although the VNIR spectra of the moons of Mars resemble those of outer-belt asteroids, the thermal infrared spectra of Phobos are reported to be inconsistent with chondrites of any class. Mars may have moons smaller than in diameter, and a dust ring is predicted to exist between Phobos and Deimos. Dozens of crewless spacecraft, including orbiters, landers, and rovers, have been sent

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
