One fairly successful approach is to bury irrigation pipes underground to feed the roots of plants directly - so minimising evaporative losses. We would need to show that we can reclaim deserts, right here on Earth. In the medium term, the steps towards terraforming are perhaps more interesting. This is based on considerations of the amount of Oxygen that a rain forest turns over per year. Timescales for terraforming a planet such as Mars using only biological methods are likely to be measured in thousands of years.

The darker planets captures more solar energy, causing it to warm up. Furrows in the ground as made by plowing decrease the albedo, making the planet appear darker. It is easier to reduce the albedo than increase it. It can be radically changed using relatively little material.

The material would need to be harvested from high orbit to reduce the 'lifting cost'.Ī planet's albedo (the fraction of incident sunlight it reflects) is a value between 0.0 and 1.0. An atmosphere would also be necessary to heat up the surface of the planet, by means of greenhouse gasses. Possible lack of Carbon and Nitrogen may require that materials to be brought from Earth.

Reality BitesĪlthough the game allows us to imagine a future where the Red Planet turns green, it may be a long time before we achieve that in reality - if ever - but that won't stop astronomers from working toward solutions.Ĭarl Sagan believed the key was melting water vapor from Mars’ polar ice to create "much more clement conditions." NASA continues funding research into potential Martian habitats that could keep the inhabitants safe from the elements. Fans of classic city-building games like "SimCity" will see the planet as a giant sandbox, ready for an expert interplanetary urban planner to step in and turn the red soil into a bustling metropolis. Watching the ant-like colonists building the city alongside Martian mountainscapes is like a meditative experience, all set to the beautiful in-game views of a starry sky. Seed the planet's red soil with lichen, brush, and trees, and once the atmosphere reaches breathable levels, you can open up the glass domes and let the colonists take a fresh breath of Martian air.

All must be carefully monitored, with the goal of bringing them closer to habitable levels. Terraforming requires a careful balance of the elements: Atmosphere, Temperature, Water, and Vegetation.
