The LRV was an open rover for a crew of two, and a range of 92 kilometres (57 mi) during one lunar day. One NASA study resulted in the Mobile Lunar Laboratory concept, a crewed pressurized rover for a crew of two, with a range of 396 kilometres (246 mi). The Soviet Union developed different rover concepts in the Lunokhod series and the L5 for ...
Direct human presence in space was achieved with Yuri Gagarin flying a space capsule in 1961 for one orbit around Earth for the first time. While direct human presence in open space, by exiting a spacecraft in a spacesuit, a so-called extravehicular activity, has been achieved since the first person to do so, Alexei Leonov, in 1965.
Mars is more suitable for habitation than the Moon, with a stronger gravity, rich amount of materials needed for life, day/night cycle nearly identical to Earth, and a thin atmosphere to protect from micrometeroids. The main disadvantage of Mars compared to the Moon is the six-to-nine-month transit time and the lengthy launch window, which ...
This category is for various types of places intended for human residence, as opposed to and often in addition to e.g., places of work, study, or entertainment. The term habitat comes from ecology , and includes many interrelated features, especially the immediate physical environment , the urban environment or the social environment .
An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
[7] [8] [9] This time range is a hot source of debate. The few agreements achieved to date are the origin from Central Asia, with widespread habitation of the Americas during the end of the last glacial period, or more specifically what is known as the late glacial maximum, around 16,000 – 13,000 years before present.

At the same time, only 0.5–1 percent of these represented villages with more than 3–4 houses. This means that the old nomadic or migratory life style continued in a parallel fashion for several thousand years, until somewhat more sites turned to sedentism, and gradually switched over to agricultural sedentism.
A Stanford torus interior (cutaway view) Interior view of a large scale O'Neill cylinder, showing alternating land and window stripes. A space settlement (also called a space habitat, space stead, space city or space colony) is a settlement in outer space, sustaining more extensively habitation facilities in space than a general space station or spacecraft.
