I know most people are excited about humans on Mars, but I&#x27;m far more excited about Venus. 40 or 50kms up Venus is actually quite habitable. Similar gravity, pressure, calm wind speeds. We could build floating cities and create oxygen with floating bioengineered plants that slowly change the oxygen content of the planet. We could use particles or strategically placed solar panel arrays to shield off excess sunlight while we slowly change the atmosphere from CO2 to O2 + other gases.<p>Mars is just a cold crappy desert.
