Today on Discovery Enterprise we take an exciting look at the possibility of transforming the planet Mars into a second planetary abode for humanity and the other life forms of our planet. What would it take to Terraform the red planet and bring life to Mars and Mars to life?
Terraforming (literally, “Earth-forming”) of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to those of Earth to make it habitable by terran organisms.
The term is sometimes used more generally as a synonym for planetary engineering, although some consider this more general usage an error. The concept of Terraforming developed from both science fiction and actual science. The term was coined by Jack Williamson in a science-fiction story (“Collision Orbit”) published during 1942 in Astounding Science Fiction, but the concept may pre-date this work.
If humanity ever succeeds in establishing a foothold on Mars and Terraforming it humanity will indeed have a long term future to look forward to.
