Moons of Mars binary asteroid that separated under tidal forces. Phobos could be a second-generation Solar System object that coalesced in orbit after Mars formed, rather than forming concurrently out of the same birth cloud as Mars. Another hypothesis is that Mars was once surrounded by many Phobos- and Deimos-sized bodies, perhaps ejected into orbit around it by a collision with a large planetesimal. The high porosity of the interior of Phobos (based on the density of 1.88 g/cm, voids are estimated to comprise 25 to 35 percent of Phobos' volume) is inconsistent with an asteroidal origin. Observations of Phobos in the thermal

Mars One's team of advisers consists of over 30 industry and scientific experts, including Mason Peck, Peter Smith, James Kass, K.R. Sridhara Murthi, Esther Dyson, and Robert Zubrin. Mars One is not an aerospace company and will not manufacture hardware. Lansdorp assumes all major components are available in the aerospace market, and he thinks he has identified at least one potential supplier for each component of the mission.
