Here i outline how to create a modified human who can live unprotected on titan without oxygen supply on a non terraformed titan.

Despite what you might think, -180 celcius air isnt that cold, because gases have terrible thermal conduction. In fact a non modified human can experience this temperature for 3 minutes safely without clothing in a cryotherapy chamber for 3 minutes. A modified human will find titan like a cool autumn afternoon.

Let me know what you guys think. Im behind the other titan colonization posts but this one has by far the most detailed science.
