As ammonia is mostly nitrogen by weight, it could also provide the necessary buffer gas which, when combined with oxygen gas, would create a breathable atmosphere for humans. Since ammonia (NH³) is a powerful greenhouse gas, its introduction into the Martian atmosphere would have the effect of thickening the atmosphere and raising global temperatures. This consisted of importing ammonia ices from the outer Solar System and then impacting them on the surface. Cole released “ Islands in Space: The Challenge of the Planetoids, the Pioneering Work“, in which he advocated triggering a greenhouse effect on Mars.
Over the past few decades, several proposals have been made for how Mars could be altered to suit human colonists. And in 2012, Kim Stanley Robinson released 2312, a story that takes place in a Solar System where multiple planets have been terraformed – which includes Mars (which has oceans).

In 2011, Yu Sasuga and Kenichi Tachibana produced the manga series Terra Formars, a series that takes place in the 21st century where scientists are attempting to slowly warm Mars. Throughout the 1990s, Kim Stanley Robinson released his famous Mars Trilogy – Red Mars, Green Mars, Blue Mars – which centers on the transformation of Mars over the course of many generations into a thriving human civilization. In 1992, author Frederik Pohl released Mining The Oort, a science fiction story where Mars is being terraformed using comets diverted from the Oort Cloud. Basically, we would have to warm the planet, thicken the atmosphere, and alter the composition of said atmosphere. Hence, if humans wanted to live on Mars without the need for radiation shielding, pressurized domes, bottled oxygen, and protective suits, some serious changes would need to be made. On the Martian surface, the average dose of radiation is about 0.67 millisieverts (mSv) per day, which is about a fifth of what people are exposed to here on Earth in the course of a year. Add to this the fact that Mars’ lacks a magnetosphere, and you can see why the surface is exposed to significantly more radiation than Earth’s.
The thin atmosphere and greater distance from the Sun also contributes to Mars’ cold environment, where surface temperatures average 210 K (-63 ☌/-81.4 ☏). Mars’ atmospheric pressure also ranges from 0.4 – 0.87 kPa, which is the equivalent of about 1% of Earth’s at sea level. And if we were going to alter the planet through ecological engineering, it would take a lot of time, effort, and megatons of resources!Īrtist’s impression of the terraforming of Mars, from its current state to a livable world. If we were to live on the planet, we would have to depend rather heavily on our technology. That being said, there are also a lot of key differences that would make living on Mars, a growing preoccupation among many humans (looking at you, Elon Musk and Bas Lansdorp!), a significant challenge. Because of this, Mars is considered a prime candidate for human settlement a prospect that includes transforming the environment to be suitable to human needs (aka. These include similarities in size, inclination, structure, composition, and even the presence of water on their surfaces. What will it take?ĭespite having a very cold and very dry climate – not to mention little atmosphere to speak of – Earth and Mars have a lot in common. But if we really want to live there someday, we’re going to need to do a complete planetary renovation.
At present, there are several plans to put astronauts and ever settlers on the Red Planet. As part of our continuing “ Definitive Guide To Terraforming” series, Universe Today is happy to present our guide to terraforming Mars.
