Visit the new Venus Sky City in this new update! It is a repairable city - you can repair the fan propellers, windows, and ship, and you earn ability points for doing so! It is made of a very light weight material, similar to Styrofoam, but far more durable. There are a number of coins and codex pickups there as well. To return to the surface of Venus, just jump down, and fall to the ground. The city itself resides in a relatively habitable zone, which is true to life - there really is a relatively habitable area in the upper atmosphere of Venus where the temperature and pressure are decent. It is mostly CO2 there though, so you would have to bring your own oxygen, and protection against the traces of sulphuric acid. It would certainly be an interesting area to explore, who knows - life may exist in this upper atmosphere of Venus.
Here are some more images of the city:
