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 ...
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.
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 ...
The United States has been using the term "human presence" to identify one of the long-term goals of its space program and its international cooperation. [1] [9] While it traditionally means and is used to name direct human presence, it is also used for mediated presence. [1]
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, spacestead, 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.
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.
Human composting is emerging as an end-of-life alternative that is friendlier to the climate and the Earth — it is far less carbon-intensive than cremation and doesn’t use chemicals involved ...
Colonization of Mars differs from the crewed Mars exploration missions currently pursued by public space agencies, as they aim to land humans for exploration. [6] [7]The terminology used to refer a potential human presence on Mars has been scrutinized since at least the 2010s, [4] with space colonization in general since the 1977, as by Carl Sagan, who preferred to refer to settlements in ...
