== In situ == 

 "Space colonization (also called space settlement, space humanization, space habitation, etc.) is the concept of permanent autonomous (self-sufficient) human habitation of locations outside Earth using In Situ Resource Utilization." 

 This is the opening paragraph of this article.  Just a couple of nitpicks: In Situ Resource Utilization is capitalized here as if it's a printed plan or program or whatnot.  Is it? Can we get a citation or a link to another Wiki article? Also, if a permanent human habitation was developed on the moon or Mars, but was not autonomous and did not use "I.S.R.U.", wouldn't it still be considered a space colony?
