I figured Discovery was merely in dock somewhere and that's the connecting corridor between the inner and outer saucer rings?
I already explained all my reasoning for why I don't think that's the case. The details in the corridor are entirely different from the corridor that connects the rings. But I fully admit I could be proven wrong when the show comes out, but for right now, I really don't think that's a saucer tube.
I must have missed wherever the use of "away team" in DSC was, but in any case, I'm pretty sure that all onscreen references, when taken together in context, comport with the following: An "away team" or "away party" is a general term meaning any group of personnel who leave the ship (or other base) on an "away mission," irrespective of destination. A "landing party" specifically refers to one visiting the surface (or interior) of a planet (or moon/asteroid/other celestial body), on occasion also called a "shore party" ("The Return Of The Archons" [TOS]) or "planet detachment" ("And The Children Shall Lead" [TOS]). A "boarding party" refers specifically to one boarding another vessel (or other free-floating facility, etc.), often but perhaps not necessarily with the added connotation that such has not been openly invited. Any quibbles with that scenario? -MMoM
When Kirk and company transported to the Botany Bay (Space Seed) it was a "landing party." Kirk: "Care to join the landing party, Doctor?"
Well, both ENT and DSC did use "landing party" multiple times. They just also used "away team" (although I still don't recall it in DSC, tbh). Nothing wrong with that. TNG occasionally used "landing party" as well. And TOS itself used other terms, too, even if not "away team" specifically. -MMoM
