Well, I'm better at working out the science and tech of a universe than anything else, but reading back through here one thing jumps out at me: Change the Argonauts' code names. As they are they don't have any real flow, rhyme, or reason to them, it's just *random word*-*Greek mythological figure* and even beyond that nearly all of them seem too long be actual code names for individuals. Personally, if you're going to do mythological code names, I'd drop the first word and just go with the second. If you want to further separate yourself from NR I'd pick a different mythology (Hindu and Abrahamic come to mind), though that's not a do or die thing. Yes, Greek has been done by NR, but a bunch of other stories have gone that route too, and I seriously doubt Scorp or Ryan had Robot Jox in mind when they made the Immortals.
So yeah, that's my two non-scientific cents. I've got a whole bank I could let loose on the "SCIENCE!" front, but as it stands I've got no starting point since you haven't really covered that.
Yeah, Drake Pertinacia-Perseus is about as rhythmic as Hurbook Fliggen-Flam. Your names need to be less dense syllabically, as well as making a little sense on the meaning front. Pertinacia, for example, is the sort of name I'd attribute to a lady of leisure in the 19th century. It sounds very Victorian. Things like these need to be brought into consideration when you are naming anyone within your universe.
