It’s a classic, if somewhat exaggerated trope in Star Trek: The ships first officer, second officer, tactical officer, chief engineer, chief medical officer, and a random ensign beam down to an unsecured planet while some dangerous problem is either ongoing or likely to occur. The Doylist reasons for this are as obvious as the Watsonian reasons it seems so silly: these are the main characters who are supposed to get the bulk of the screen time, so they are constantly thrown into situations which real world commanding officers and department heads are generally kept well clear of.
But what if this wasn’t the precedent established in TOS and continued in every subsequent series (including, to a slightly lesser but very real extent, Lower Decks)? What would a Star Trek show look like which still had senior officers who we are meant to care about and who still get significant development and screen time, but who aren’t thrown into unrealistically dangerous situations on a regular basis? Could such a show survive telling stories without visibly putting those regulars lives on the line so frequently? Would it be viable to keep the focus on things that happen either aboard ship or in nominally safe situations? Alternately, could a show successfully develop a cast of lower ranking “away team” characters who get the “dangerous” screen time while keeping significant focus on the major decision makers on the bridge? And how could the shows manage such a visible separation between “expendable” and “not expendable” crew while maintaining that humanist, optimistic, everybody-has-an-equal-right-to-life ethos?
It wouldn’t be an easy thing to pull off, certainly. But how could it have been done?
I think it would be cool if the away team was different, or nearly different, each episode. You’d have temporary characters to empathize with (much like the alien species usually have), but then cut back to the senior crew dealing with problems on the ship and/or the moral ramifications of what the away team is dealing with. I think it would have to be a show with longer episodes, but we mostly have that now with steaming.
You could even have a different senior crew member leading a team of junior officers from their department. This could still give senior officers action, but provide a lot of variety, examples of mentoring, etc.
