Moons of Mars attention when Houston's claim was repeated in earnest by a Soviet scientist, Iosif Shklovsky, who, based on a later-disproven density estimate, suggested Phobos was a hollow metal shell. Searches have been conducted for additional satellites. In 2003, Scott S. Sheppard and David C. Jewitt surveyed nearly the entire Hill sphere of Mars for irregular satellites. However scattered light from Mars prevented them from searching the inner few arcminutes where the satellites Phobos and Deimos reside. No new satellites were found to an apparent limiting red magnitude of 23.5, which corresponds to radii of about 0.09 km using an albedo of
Mars One men and 50 women from the total pool of 660 from around the world were selected to move on to the third round of the astronaut selection process: Applicants were remotely interviewed and recorded by Mars One over a relatively short Skype/SparkHire call regarding Martian-related orbital, temp/pressure, geological and historical parameters and the specific elements of the Mars One one-way mission. Joseph Roche, one of the finalists, has accused the selection process of being based on a point system that is primarily dependent on how much money each individual generated or gave to the Mars One organization, despite many of
