Terraforming is the controlled modification of a region of the planet or whole of it, to make it habitable for Humans. The aim Terraforming is to transform a specific region or the whole of the planet, making it habitable for human, by reproducing earth like environment. There are eight planets, many dwarf planets and satellites in our solar system which can be used as a place for testing human knowledge and capacity to create new worlds. Among the solar systems planets and satellites very few can be made habitable for humans, because humans require a specific set of climatic and terrestrial condition to sustain. For finding Terraformable planets we must look at the members of solar system which might sustain life. From the data collected from recent space missions Mars, some satellites of Jupiter and Saturn may have primitive life forms. Among the solar system members, some can be considered for Terraforming, while others will provide the necessary tools for the same, which will be described in detail later.
The first part describes the necessity of Terraforming. It also describes the changes required on an alien planet to make it habitable for humans and the tools.
The second part describes various methods of small scale climate control or planetary engineering to make contained part of the planet human habitable. The third part describes methods for Terraforming planets in a much larger scale. Which includes global atmospheric transformation, change in planetary composition and stimulation of large scale events on an alien planet to make it habitable. The third describes environmental adaptation. It explains without changing the planetary environment we can live on the planet by making necessary changes in the organic life forms and human mutation.
At the last the Terraforming is debated through its applicability, feasibility and necessity. It also explains the risk humans and the alien life forms have to endure for the mega projects.
