We can't land on the surface of Venus. At least, it would be almost impossibly difficult to design a spacecraft that could survive the planet's hellish environment. With a carbon dioxide rich atmosphere at a pressure about 92 times what we feel on Earth and an average surface temperatures upwards of 900 degrees Fahrenheit, it's not a welcoming environment. But about 31 miles above the surface, Venus becomes almost Earth-like. Above most of the clouds there's enough sunlight to provide solar power, the temperature is colder but still warm enough for liquid water to exist, and the gravity is about 90 percent of what we feel on the Earth. The gases at that altitude can also support life, albeit with a little help. There's more than enough carbon dioxide for plant growth. The nitrogen in the atmosphere along with hydrogen gathered from floating sulfuric acid droplets could be turned into the necessary elements to support human life.
