Solar eclipses on Mars a Martian day is 24 hours 37 minutes long, meaning that Phobos can create two eclipses per Martian day. These are annular eclipses, because Phobos is not quite large enough or close enough to Mars to create a total solar eclipse. Deimos is too small (about ) and too far from Mars to cause an eclipse. The best an observer on Mars would see is a small spot crossing the Sun's disc. Both moons are too small to cast a shadow on Mars that can be seen from Earth. However, shortly after the first artificial satellites were placed in orbit
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
