OK, now I totally want to go to what ever academy they open up for this branch and officially become a Space Cadet! :-)
More seriously, this isn't much different that the Army Air Corps becoming the Air Force, logistically it opens up a branch that can have strategies and priorities that are not constrained by its original branch (the original Air Corps was constantly arguing with the Army over what was more important, tanks or airplanes, for example). It also opens up a bunch of jokes for late night comedians like "Look, it is a new customer for the F35 Joint Strike Fighter, now its required to operate in a vacuum!"
