Looks like Mormons would do well in space. A series of articles being done on various religions and how they would fare in space and handling Martians and other aliens that invade our solar system (would they be illegal aliens?).
With our views of Kolob, materialism/spiritualism, and God creating new life and planets continually, it makes for a comfortable view of the universe for most Mormons. Yes, Joseph Fielding Smith did not believe we should have anything to do with space, but I believe most of us today think it is generally a good thing.
