Nuking Mars to Terraform It

Over the years  SpaceX successfully reduced cost of space travels, reused a rocket and created space tourism. However, the biggest goal- colonizing Mars- still seems like a distant dreams to many. Elon Musk keeps coming up with ideas on traveling, terraforming, and living on the Red Planet. For years ago on "The Late Show With Stephen Colbert" Musk discussed the strategy of terraforming Mars by nuking it. Recently, this concept came back, shocking the public and creating a lot of controversy. So, is nuking Mars the best way to make it suitable for humans? Will it even work? And finally, how far humans can go to change the environment?

How nuking Mars can change its climate?

Musk's plan is to detonate nuclear bombs over Red Planet's poles. This would vaporize the ice caps, liberating water and carbon dioxide. Those two are potentially greenhouse gases, so as a result the planet would start warming. Furthermore, the nuclear fusion would create artificial suns by very low fallout explosion above atmosphere. Likewise our Sun, this would not cause Mars to become radioactive. When asked about the risk of that project, Musk tweeted "Not risky imo & can be adjusted/improved real-time. Essentially need to figure out most effective way to convert mass to energy, as Mars is slightly too far from this solar system's fusion reactor (the sun)". He seems to be very sure about that idea (there is even a T-shirt!) however it rises a lot of controversy from the public and scientists as well.

Controversy

First of all, recent study published in Nature Astronomy suggests that this strategy might not work. Team members concluded that there is not enough CO2 to create significant changes in the climate, even if all of it were liberated. Moreover, the team also proved that water vapor should not be consider as a potential warmer. " "Previous models of atmospheric warming have demonstrated that water cannot provide significant warming by itself; temperatures do not allow enough water to persist as vapor without first having significant warming by CO2,". They also concluded that terraforming Mars using today's technology is not possible. In addition, this project can be more dangerous than it seems. Despite lack of effects, it can trigger the event we know as "nuclear winter", when dust and particles block parts of sunlight (similar asteroid impact killed the dinosaurs).

The SpaceX dream

Musk wants to make Mars suitable for humans, and this for sure requires unusual, groundbreaking solutions. It seems like nuking the Red Planet will not be the successful one, however SpaceX will keep on trying. In 2017 he believed there will be a city on Mars in less than a century. In addition, the idea of nuking Mars also woke the controversy on how far will Musk go to achieve the SpaceX goals, and where is the border of humans intervention in natural planet's climate. Wherever he goes, many will for sure follow his visionary ideas and hope most of them will come true.
