How would the Earth look like if it had a ring system like Saturn?
“The terraforming of Mars is the hypothetical process by which the climate, surface, and known properties of Mars would be deliberately changed with the goal of making it habitable by humans and other terrestrial life, thus providing the possibility of safe and sustainable colonization of large areas of the planet.
Based on experiences with Earth, the environment of a planet can be altered deliberately; however, the feasibility of creating an unconstrained planetary biosphere is undetermined. Several of the methods described below may fall within humanity’s technological capabilities, but at present the economic resources required to execute such methods are far beyond that which any government or society is willing to allocate to such a purpose.”
Fascinating
