Moons of Mars 0.07. If viewed from Mars's surface near its equator, full Phobos looks about one third as big as a full moon on Earth. It has an angular diameter of between 8' (rising) and 12' (overhead). Due to its close orbit, it would look smaller when the observer is further away from the Martian equator, and is below the horizon and thus invisible when viewed from Mars's polar ice caps. Deimos looks more like a bright star or planet for an observer on Mars, only slightly bigger than Venus looks from Earth; it has an angular diameter of about 2'. The
Mars One in 2012 was Astrobotic Technology. On 12 March 2013, Paragon Space Development Corporation was contracted to develop concepts for life support and the Mars Surface Exploration Spacesuit System, and it includes the pressure suit and the Portable Life Support System (PLSS) that permit survival outside the habitat. The suggested supplier of the suits is ILC Dover. The study was stated to be finished late summer 2013; Mars One released the results of this (ECLSS portion only) study to the public in June 2015, but did not fund its research and development. In 2013, Mars One signed a contract with Paragon
