So far in my Fantastic Future series I’ve written about terraforming the inner solar system. It is a nice start to expanding human civilization, but the inner solar system really only gives us (if we terraform Mercury, Venus, and Mars) a little more than one and a half extra Earths. If we distributed the Earths population across the inner solar system it would still be as crowded as pre-World War Two Earth. In order to really expand we need to look at the outer solar system.
The gas giants themselves can’t be colonized or terraformed but they all have complex systems of moons. Jupiter has Europa, Ganymede, and Callisto which all would be considered at least dwarf planets if they were in there own orbit, Ganymede is 8% larger than Mercury.
Unfortunately it is a bit chilly out there, -261.67 ° Fahrenheit and these worlds are within Jupiter’s magnetosphere making the surface have high radiation.
The advantage of these worlds is the gas giants have nearly unlimited amount of energy that can be gathered from the upper atmosphere in the form of Helium 3 for use in fusion reactors.
Using that unlimited energy instead of trying to live on the surface colonists could burrow down about a mile under the ice and set up tubes in the underground oceans of these worlds.
Here on Earth the pressure at a depth of one mile would crush anything we could make, but on these worlds the gravity is one-sixth of what is on Earth so the pressure would be considerably less.
Even if it turns out the pressure at that depth is too great, the unlimited amount of energy supplied by Helium 3 fusion reactors could warm up the oceans until the ice layer was thin enough to place a habitat that wasn’t under that much pressure, but still thick enough to keep the water from being exposed to the vacuum of space.
By expanding human civilization to the outer solar system we could easily have the equivalent of 11 to 12 Earths. That is enough room for every human to spread out and never have to worry about scarcity again.
I am slowly combining my two personalities Project Savior, known on the internet for writing comments and posts and Darrell B. Nelson the semi-professional author who has had his work published in Ray Gun Revival, Distant Worlds, AlienSkin Magazine, Bewildering Stories, Cynic Magazine and the author of the collection of short stories “I Killed the Man That Wasn't There”.
Feel free to laugh with me, or at me, as I merge these two personalities in a whole being. Feel free to email me at project.savior (at) yahoo (period) com.
