Why We Should Build Cloud Cities on Venus

What an amazingly cool idea. This article is full of science and technology ideas that would get us to Venus, which is really a much more Earth-like environment than Mars appears.

But the atmosphere of Venus, Arney and Jones argue, is “probably the most Earth-like environment that’s out there.”

Up in its clouds, temperatures are more Earth-like, and due to its size—roughly the size of Earth—the planet boasts a gravitational pull that’s only 90 percent of Earth’s, something which would be immensely energy-intensive and mechanically complex to simulate elsewhere. This is what earned Venus its other nickname: Earth’s twin.

Venus is also easier to get to than Mars. You can travel to Venus in five months whereas Mars takes nines. If you’re taking the shortest path, opportunities to travel to Venus come once every 1.6 years, whereas the optimal window for Mars comes every two years. Moreover, while both planets boast ample amounts of volatile life-sustaining materials like hydrogen, carbon and nitrogen, only Venus’s dense atmosphere would be helpful in shielding human colonists from the harsh assault of solar radiation. Mars, meanwhile, has almost no atmosphere, leaving the Red Planet in a deep freeze and putting future Martian colonists in danger of irradiation.
