Venus’s gravity is 90 percent of Earth’s, and it’s easier to get to than Mars, reachable in just five months as opposed to nine for Mars.

The surface of Venus is a place of crushing pressure and hellish temperature. Rise above it, though, ​and the pressure eases, the temperature cools. Fifty kilometers above the surface, at the base of the clouds, the temperature is tropical, and the pressure the same as Earth normal.
