Apparent retrograde motion notable on Mars which has two natural satellites, Phobos and Deimos. Both moons orbit Mars in an eastward (prograde) direction, however Deimos has an orbital period of 1.23 Martian sidereal days, making it supersynchronous, whereas Phobos has an orbital period of 0.31 Martian sidereal days making it subsynchronous. Consequently, although both moons are travelling in an eastward (prograde) direction, they appear to be travelling in opposite directions when viewed from the surface of Mars due to their orbital periods in relation to the rotational period of the planet. All other planetary bodies in the Solar System also appear to periodically
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
