Well, in a sense, the Morrow Project has certain sci-fi elements to it such as people being cryogenically frozen, fusion power for the vehicles, universal poison antidote and so on, some say the man behind the Project, Bruce E. Morrow was a time traveller or slider and he has been using that to get technology for the Project since the early 1960's. You do have some "deus ex machina" there, the fusion itself is to prevent the Project Teams from playing "fuel trek" (ala Twilight: 2000) to keep things running so their missions will not suffer
Some "Project Directors" (PD's - refs) put in things like a few insular advance societies that have robots and clones like in one Play By E-Mail (PBEM) I'm in but those are few and far between. Also in that game, there was an EU version of the Project, not associated with the Morrow Project, to where they built some space stations, 3 I think and from what I can guess, they might have a Moon base too.
Twilight: 2000 is more "alternate history," World War III breaks out between the USSR/USA, Warsaw Pact/NATO in 1996, there is al imited nuclear war in 1997 and your players are stuck in Poland in the year 2000 with the war still going on in low gear to where the general idea is to find a way back home or at least survive.
