Saturn's largest moon may be the only place beyond Earth where humans could live
Two thoughts on this topic:1. The film Gattaca (1997), in addition to being an excellent, inspiring film all around, centers on an aspiring astronaut's upcoming trip to Titan. Highly recommended.- https://www.youtube.com/watch?v=lZa83dTf4JA2. The colonization of Venus is also a fascinating idea that isn't talked about much in comparison to the Moon or Mars. Essentially, the surface is too hot for colonization, but it may be possible to build floating cities ±31 miles above the surface.- Venus's atmosphere is made mostly out of carbon dioxide. Because nitrogen and oxygen are lighter than carbon-dioxide, breathable-air-filled balloons will float at a height of about 50 km (31 mi). At this height, the temperature is a manageable 75 °C (348 K; 167 °F); or 27 °C (300 K; 81 °F) if we could get 5 km (3.1 mi) higher- The atmosphere also provides the various elements required for human life and agriculture: carbon, hydrogen, oxygen, nitrogen, and sulfur.- Additionally, the upper atmosphere could provide protection from harmful solar radiation comparable to the protection provided by Earth's atmosphere. The Atmosphere of Mars, as well as the Moon provide little such protection.https://en.wikipedia.org/wiki/Colonization_of_Venus
