Terraforming projection

A thirty-year projection of terraforming Velara III

Terraforming was the process of modifying the environment of a planet or moon to make it habitable for life found on class M planets.

Its converse is bioforming, which is the process of adapting a species to the planet. (TAS: "The Ambergris Element")

Parts of a planetary surface could also be adapted to humanoid life by building artificial biospheres. (TNG: "The Masterpiece Society")


Terraforming begins with selecting a planet which has the right mass, gravity, rate of rotation, and balanced periods of day and night. Federation efforts at terraforming were coordinated by Terraform Command and ensured both that there is no life on the planet, and that it never will naturally occur. Next, water must be made available for life in water basins. This could be done using hydraulic landscaping, sometimes with the additional step of filtering and re-oxygenating the subsurface water. Then, microorganisms are introduced to provide an arable biosphere.

One of the key metrics of the process being successful is monitoring the amount of vegetation on the planet.

The process of terraforming could take around 30 years. (TNG: "Home Soil")



The universal atmospheric element compensator might also be a terraforming device.
