I was reading an interview with the show runners and came across this interesting bit:

While Star City's sister show For All Mankind has made 10-year time-jumps at the end of each season a regular thing, the creators of the Soviet-based series don't think they'll continue that trend here.

"I think there may be little jumps," says Nedivi. "But I don't think we're looking to do the kind of decade jumps we do with For All Mankind. One, that's taken a toll on us and the cast and everyone in terms of the aging process. It's enough to have to do them on For All Mankind. But two, I think because of the storytelling on this show, it doesn't feel as necessary. I mean, that show, we did those jumps in time because we're trying to show the butterfly effect of the space race continuing and how it would change. So I feel if we did it on this show, it'd be basically mirroring For All Mankind, and our goal here is not to do that. Our goal is to create within the realm of Star City and the space program and tell the story of these characters in real time and see them evolve. If we're lucky enough to be able to do that, I think that's how we would approach it."

So, it's going to be a very different vibe. Less "grand sweep of history" but instead a tighter focus.

If nothing else, I guess that means that we won't see Irina's complete story, but instead the beginning and the late stages.

(also, I have to admire the interview writer or their editor for the section header "Danger Уилл Робинсон, Danger". Yes, that translates to Will Robinson....)
