NASA Design Reference Mission 3.0
NASA Design Reference Mission 3.0 was a NASA study for a human space mission to the planet Mars in the 1990s. It was a plan for a human exploration architecture for Mars, and was released in 1998 as an addendum to the early design plans released in 1994. The plan is for a series of multiple launches to send various space transportation, surface exploration hardware, and human crew to Mars, and to return the crew to Earth in the early 21st century. Various technologies are explored to launch the payloads into space, to send them to Mars, and to reduce overall weight of the mission by various technologies or techniques including nuclear, solar, aerobraking, and in-situ resource use. Overview The study was performed by the NASA Mars Exploration Team at the NASA's Johnson Space Center (JSC) in the 1990s. Personnel representing several NASA field centers formulated a "Reference Mission" addressing human exploration of Mars. The plan describes the first human missions to Mars with co ...

Mars Design Reference Mission 3
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of Mars surface color, its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () Atmosphere of Mars, atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, Groundwater on Mars, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and Martian polar ice caps, ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half List of Solar System objects by size, as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Martian regolith#Atmospheric dust, Fine dust is prevalent across the surface and the atmosphere, bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
