Elon Musk proposes another trace (that bomb) to transform Mars

Follow Elon Musk, SpaceX's fantastic founder, on Twitter is a guarantee of some colorful declines. Sooner or later, the natural returns to the gallop and the social network until the blue bird is often in the forefront to attend these sequences in automatic operation. Recently, he gave us an unforgettable, viral sequence where he dug his old slogan, almost a meme: "Nuclear Mars!" ("Drop a Mars Atomic Bomb!").

This phrase, which seems to come from a child (or a furious bastard), has its origins in the fascination that the entrepreneur has always felt for the Red Planet. With these bombs, he does not want to break it anyway: Musk is a constant supporter of Mars colonization, a goal he has always claimed and assumed through his company SpaceX. The idea behind this noisy formula is to actually blow up nuclear fusion bombs, creating a bit of a lasting radioactive outcome during the beautiful atmosphere of Mars. This will have the effect of duplicating the effect of the solar radiation, which will warm the Martian atmosphere without making it completely radioactive. An idea that obviously makes a lot of skeptics, both on the NASA side and the public.

But much more is needed to get Musk to give up his quest terraforming from Mars. Two days ago, in another Twitter conversation, he posted another trace. According to him, it might make sense to warm Mars with thousands of mirrored satellites!

Although not mentioned, this idea comes directly from Rigel Walda of the University of Arizona. In 2006, Rigel won the NASA award for studying "the use of lightweight, wide-open mirrors to shape the territory of Mars's surface so that people can colonize it economically." Volda's study, published here, is fascinating. The advanced principle is simple: by deploying many satellites, equipped with light and reorientable mirrors, it would be possible to focus the reflections of all these mirrors on a point on the surface to heat significantly – up to 20 ° C!

Volda is in any case convinced of the feasibility of his project: he concludes his study by explaining that, in his view, the engineering prerequisites for heating a small part of Mars are thus out of reach. Musk and SpaceX have already proven their knowledge of deploying satellites, even in large numbers. It is therefore easy to understand why the charismatic guru of the company is so attracted to this solution. The placement of mirrors in orbit is certainly less likely to be confirmed by Michael Bay than a permanent nuclear explosion through Mars, but it has the merit of relying on already available technology that looks far less risky and risky. It remains to be seen how this issue will develop with the advent of education. It is not forbidden to imagine going hand in hand with redefining priorities and that SpaceX is going to Mars through mirrors in its wallet!
