Captain X, I've just "ST: Foundations"'s "One Small Step," and I really like it!
There are a few technical issues, though. As I noted above, "Star Trek" is owned by CBS Studios now, not Paramount, so you might want to change your copyright notice to reflect that. Also, you should be aware that under US law, fan fiction writers have no copyright claim to their works unless they have a license agreement to that effect with the trademark owners. So you should probably remove any claim to copyright ownership of your fics.
It's not spelled "Concilate." The term is "Consulate." A consulate is basically a satellite embassy -- an area of foreign soil located in a major population center away from the Embassy, which is usually in the host state's capital. So the Vulcan Consulate wouldn't file a protest with the United Earth Senate; rather, if you're going to use building lingo, you'd say that the Vulcan Embassy filed a protest. Of course, more formally, it would be the Vulcan Ambassador.
I love that it's being called UESPA and not Starfleet.
If you were to revise "One Small Step," it might be a good idea to note that the UE Senate has decided to postpone the Enterprise's mission very suddenly. Launching a ship is a major thing that would have been planned long in advance; the idea of the Senate postponing it at the last minute, instead of postponing it months beforehand, is pretty extraordinary. (Maybe a Senator had a sudden change of heart because of the Vulcans?)
"United Earth Military." That's a fairly unrealistic name; military forces don't use the term "military" in their name, because it's a descriptive phrase for specific services. It's the same reason that the New York Police Department calls itself the NYPD instead of "New York Law Enforcement Agency." (There being multiple law enforcement agencies besides the PD.) I'd suggest finding a new name -- perhaps something specific to the type of combat it tends to engage in. "United Earth Space Force," for instance, or, if you want to be more generic, "United Earth Defense Force."
Soval as "senior Ambassador to Earth." In international relations, there's no such thing as a "senior ambassador" to another state. States exchange ambassadors, who have aides with various diplomatic titles that are below that of ambassador. A country may have its Ambassador to State A joined by another ambassador for a specific issue, but the second ambassador is not an ambassador to State A, but, usually, an ambassador-at-large or some such.
I like that you involve the UE government and politics from the very beginning!!

You seem to establish that UE uses a presidential model of government; I was wondering if you'd considered having it be a parliamentary government? This has been estbalished in the novels, and I think it might make for a more interesting set-up, since parliamentary government often have more factions than presidential systems. Also, it's a bit less US-centric. Is the Senate the only leiglative body, or is there a lower house as well?
Just some nuggits for thought. I know you're thirteen episodes into it, though, so some of my ideas might be impractical even if you wanted to go with them. Thanks for your time!
