Terraforming Mars: The Popular Choice

Currently, Mars is the best conceivable option for terraforming. It’s close enough to access, (we’ve already landed our technology on Mars, just not ourselves) and has the basic building blocks to potentially become a habitable planet.

But as we’ll learn, utilizing these resources is neither simple nor easy.

Mars is surprisingly similar to Earth in many ways. It once had an atmosphere, so there is a chance that it could have an atmosphere again.

Also, it once had warm, flowing water, and we know there is frozen water on the planet. With the basic building blocks in place (probably), Mars is far and away the popular choice for the first terraforming efforts.
