Well, that was fun
N.E.W. p69 Sasha Bolotnikov is listed as having the Astrogation skill, but her careers give no access to it.
Compounding this problem, the N.E.W. space travel system requires regular astrogation rolls but only three origin careers (Farmhand, Navy Brat, Service Droid) and *no* standard careers give access to it or its category (which is [vehicle]).
If I may suggest a fix: add Astrogation to the skill list for Academy, Navy Cadet Cruise, Navy Tour, Pilot, and possibly also Smuggler and Space Jockey
Look for Navigation. As noted on p21, it's interchangeable with Astrogation (though I know the phrasing isn't super-clear).
