It's one of the most famous environments in all of Star Wars: Cloud City. That scene where we first meet Lando with the sunset in the background is a truly epic science fiction moment! If there's one place in that galaxy far, far away I'd like to visit, it's Cloud City.
Now NASA is making plans to build its own floating colony much closer: on Venus. We typically think of the planet Venus as an uninhabitable greenhouse wasteland complete with sulfuric acid storms and crushing atmospheric pressure. That's all true, but above the clouds of deadly acid, it's actually a balmy, earth-like planet.
In fact, Venus is often called our sister planet. It has a similar size and gravity, and even at altitude, the atmosphere is sufficient to shield humans from harmful solar radiation. It's also much, much closer than Mars, which makes travel there far more feasible.
That's why NASA's proposed floating cloud base is such an exciting idea. Trying to land a spacecraft on the surface is ridiculously hard. But an airbase could hang permanently above and allow humans and robots to study the unique atmosphere in relative safety.
