Preview ‘Star Trek: Discovery’ Episode 410 With New Photos Plus Trailer And Clip From “The Galactic Barrier”

The fourth season of Star Trek: Discovery is heading into its final episodes with the release of episode 10 (of 13) this week. We have new photos, a trailer, and a clip to get you started.

“The Galactic Barrier”

The new episode, titled “The Galactic Barrier,” debuts on Paramount+ on Thursday, February 24. It features the return of Blu del Barrio as Adira, and the return of a lot of recurring characters including David Cronenberg as Dr. Kovich, plus a new character – Dr. Hirai, played by Hiro Kanagawa, who will be in the final four episodes of the season.

Captain Burnham and her crew must go where few have gone before: beyond the Galactic Barrier. Meanwhile, Book learns the truth of what drives Ruon Tarka.

The episode title and synopsis appear to be referencing the second pilot of Star Trek “Where No Man Has Gone Before,” which first featured The Galactic Barrier.

I get a real kick out of Kovich. 1100 years from now and the guy is still wearing a suit and tie.

I think it’s cool 😎

And the only pair of glasses we’ve seen in Star Trek since Kirk’s readers.

Doctor Migleemo on Lower Decks also wears glasses.

We’ve seen then in TNG’s “The Big Goodbye,” “First Contact” and “Time’s Arrow,” DS9’s “Emissary,” “Our Man Bashir” and “Far Beyond the Stars,” a deleted scene in Star Trek: Insurrection, Enterprise’s “The Forge,” Star Trek Into Darkness, Voyager’s “Inside Man,” Picard’s “The End is the Beginning” and “Nepenthe,” six episodes so far of Lower Decks featuring Migleemo, and… well, that’s all that comes to mind, actually, but I could be missing some. :)

For someone who has predominately been behind the camera he is a really good performer. Feels like he is playong himself however lol

Super curious what’s going on in those scenes with Saru, Kovich, Ndoye and the new doctor.

Did they really shoot in that same quarry – again? If so, this is a real black eye on Toronto and the Locations manager.

I dunno, maybe consider it a throwback to how all the older shows would keep finding planets that looked like the Greater Los Angeles area!

In the best tradition of classic Doctor Who, all alien planets look like quarries.

Remember this was shot during the height of covid. They were very limited on where they could get to for locations and be able to meet all of Canada’s requirements for location shooting. It’s a hella lot better than a soundstage made to look like a planet which is all we had in the 60s and even much of the next generation…

Maybe Book and Ruon are on Talos IV.

I take it you haven’t heard about the pandemic.

Disco’s answer to Vasquez Rocks.

All we need now is for the new JJ film to be shot entirely on redressed Disco/SNW/PIC sets and we’re pretty much back in the classic era.

T’Rina in full “I own 51% of this company executive realness” power suit mode.
And look! They’ve remembered Adira is a character in this show!

If only they could leave Adria at acting school

I honestly didn’t mind a couple of episodes without her. I find them a bit irritating because the show had them overshadowed by Stamets and Tilly and forgot to highlight their scientific brilliance on display. On the other hand I honestly couldn’t stand the mushiness of Gray at first but he/ they really grew on me during Stormy Weather because he showed real social competence. And then he leaves the ship :(

…without “them”. Sorry. (I don’t know what to think of the whole pronoun thing, though I do respect the actors and characters wishes, of course).

“Them” isn’t a hard concept. Assuming you’re a male and I always referred to you as she/her, you would correct me and say you want to be called he/him. Those are your pronouns.

If you find someone’s wallet on a sidewalk and you don’t know it belongs to, you would say “I wonder who this belongs to, they must miss it, I would like to give it back to them.” Those pronouns are pretty much used all the time like this when you are not aware of what binary sex the person they belong to is. Just extend that to people that don’t identify as binary and it’s just business as usual.

^^That is a pretty good explaination of this subject actually, thank you.

DME, I’m sorry my dear, but you are up for elimination.

T’Rina…. on the main stage you have…. Ni’Var looked better. Condragulations! You’re the winner of this week’s challenge. You’ve won a coveted RuPeter badge and a date with Saru!


I like Adira and wish they’d show up more, but the writers seem to have no idea what to do with the character, who has contributed little to the show. Gray contributed even less and has thankfully left the playing field, as Ian Alexander is not an overly gifted actor. He was dull on The OA, and he was dull on Discovery. But Adira? A fun character played by a fun actor. It’s a shame, as the writers were doing something important in bringing gender-fluid and trans characters to Star Trek. Sadly, they did nothing with the concept and badly miscast one of the two.

One of the things I am truly loving about Discovery is its focus on the Federation council and the representatives themselves. Due to the 32nd century circumstances, it’s the first Star Trek show that is so centered around these elements. All the prior shows, the Federation council was basically just a name drop in an episode here and there; but we never actually saw it or had a real clue who the players were. We only seen the Federation President twice before in TUC and on DS9, but just in a single story. Now we have President Rillak who has become the face of the show this season as the main stars. She’s practically in every episode. And I love seeing the representatives from other worlds and are becoming recurring characters themselves.

I wanted this season to focus on rebuilding the Federation so we can get more of these elements. And while the season is obviously not solely focused on that, the DMA plot has managed to make them even more vital. If this same story was happening on TOS or TNG, we would’ve just gotten a communique from them on how the Enterprise were to proceed and then watch the senior officers on the bridge hash out a plan. It’s nice to finally see this side of mitigating a crisis for the first time.

If people think Discovery is still a bad show with no redeeming qualities, obviously it’s their right to believe that. But no one can say with a straight face, especially in the last two seasons, that its not trying to tell stories in unique ways we haven’t gotten in Star Trek until now; even if the stories themselves are still lackluster at times.

Does the Federation Council exist in the 32nd century?

It seems like power is vested in the presidency, where in the past (at least from the limited moments we’ve gotten in the 23rd and 24th centuries) the president seems to be just the leader of the council, and there’s a lot of mentions of the Federation Council as a whole making decisions as a whole.

Did you not watch “…But to Connect”?

That entire episode was based around the Federation Council and they even invited non and former Federation citizens to be part of the assembly vote on actions with the DMA. The President had no more power than anyone else and even let Burnham speak for her.

She is very democratic, but she is also still the President and can make certain calls on her own when the need arises.

I did watch it and found the entire process confusing, since it was unclear if there was a “council” (like an actual official body of government) or just the votes of member worlds mixed with non-members.

OK, I understand your point better.

I think there is a Federation Council and who decided to bring other planets throughout the galaxy to discuss an action on what to do with the DMA. Rillak may have more authority than previous Presidents pre-Burn but I don’t think sole power or anything. And they obviously have less Federation members than before so that probably extends to the council as well.

But I do agree it was a bit confusing in terms of how or if they voted for the actual resolution. I assumed all members in the Council just voted separately and not as one entity, but just a guess.

I for one have enough of the same query location being used over and over for every planet! Where are they now, back on Keminar? I bet there are other visually interesting locations around Toronto where they could shoot an alien planet. Stargate SG 1 was filmed in the same forest for years, but it never got old. I, for one, can’t unsee this location.

Looks like the same location on Talos.

There must have been something that happened in Toronto that limited where they can go shoot in the past year… What was it?

Seeing that pics I hope that episode is not about talking in the council the whole time and only moving the plot in the last 5 minutes by passing the great barrier. That would make 10 episodes for a plot which could be wrapped up in 2 episodes. I thought the purpose of reducing 24 to 13 episodes was to put the focus on the story line without “filler episodes”, so that you don’t need those additional episodes to fill the season…and not to extend 3 episodes to 13.
Enterprise season 3 did it right.

In the previous previews, the trailers and photos usually only cover the first ten minutes of the show.

I hope so!

I can’t wait to put the TV volume up to 100 so I can hear Sonequa whisper her lines

Try upgrading your sound system?

I like those set pictures, they feature colors that are later nowhere to be seen in the actual show with its depressing lighting. I feel bad for the set and costume designers, half of their work goes to waste and unnoticed this way.

Try tuning your TV brightness or contrast? These shots look the same as what I saw on TV.

Discovery will be true to form, exploring their feelings for 90% of the show, saving actual plot advancement for the final 5 minutes.

My words too!

I can’t wait to rewatch the whole season 5 times faster and finally see a double-episode in real time.

Species 10-C is Tilly.

mega-looooooooool !!!!!!!!!!!!

Yes! I’ve been waiting a long time for Starfleet to go once more beyond the Galactic Barrier and go hopping galaxies! And I want to see Kelvans as they really are, immense beings with a hundred limbs that resemble tentacles!

Starting to feel frustrated having watched this episode. The pace of story reveal this season to me has felt quite slow, and with only 3 episodes left, I am hoping they can land the conclusion in a satisfying way, and that species 10c is exciting enough to make up for having to watch 10 meandering episodes (assuming they reveal something substantial in Episode 11!).

I appreciate they are trying to find more for the bridge crew to do, but certain scenes have felt very forced (this week the Brice scene just seemed a little tacked on).

Yes. By reducing the season from 24 to 13 episodes you would expect that they show the content of 13 episodes in a row to focus on the arc and to leave out filler episodes. Instead of that they extend 3 episodes to 10…
And people complain that Star Trek: The motion picture was too slow (I don’t). In 135 minutes TMP there happens more than in 10 episodes Discovery…

In “By Any Other Name”, it would have taken the Enterprise two thousand years to reach Andromeda at maximum warp (Warp 8 or 9).

How can Discovery reach another galaxy in considerably less time? It would need someone like the Traveler to help them. The Spore drive should not be enough, should it?

Of course they can do that. Never heard of the sporedrive-Einstein-Rosen-bridge? Ups, wrong sci-fi-franchise ;-)


If they could connect the spore drive with wormholes… That should work.


Actually, the Einstein-Rosen bridge is another name for wormhole. So you got the right franchise. :)

By the way… the series finale ends with Discovery stranding in another galaxy. The follow-up-series will deal with their return to your galaxy and crossing empty space between both galaxies, running out of resources, and so on… Hmmm… that sounds familar…

Stargate Universe or Voyager, lol.

Star Trek turned into Andromeda so gradually, I barely even noticed…

Yes… Star Trek Voyager: The Next Generation. Inspired by Stargate Universe (which I prefered over the other SG-series). But seriously: After exploring the beta and gamma quadrant the next step would be exploring another galaxy. Which I expected from Disco. They have the spore drive and 900 years ahead. So many potential which isn’t used…

Agreed. That said, this does feel more appropriate for a set-up for a spin-off rather than for Discovery. I’d rather it was used to launch a 32nd Century version of the Enterprise dispatched on a mission to explore another galaxy.

They could even use the Kirk character from Singer’s Federation pitch as the lead.

In TNG:”Where No One Has Gone Before,” the Traveler did send the Enterprise NCC-1701D hurtling out of our galaxy, through two galaxies, to the far side of M33, the Triangulum Galaxy, over 2,700,000 light years in a few minutes, but the Enterprise D with its own next generation warp drive would have taken over 300 years to get home, at maximum warp. The Andromeda Galaxy is a bit closer than Triangulum, about 2,500,000 light years away, so the Enterprise D would have taken slightly less time to reach Andromeda, a reduction of one to two orders of magnitude of the Enterprise NCC-1701’s travel time. Presumably, Starfleet took notes on the Kelvans’ modifications of the 1701’s warp engines (but not on Rojan’s crew’s mods to that ship’s shields and hull?)

And I imagine that in the many centuries between the year of that episode, 2364, and the year of the Burn, circa 3069, Starfleet would have further reduced the travel time by at least a few orders of magnitude, so that the “thousands of years” in “By Any Other Name” and the 300 years in “Where No One Has Gone Before” would have been reduced to a few months.

But while a ship flying through the intergalactic void would have few celestial bodies to navigate around, it would have few shores to put down for repairs or rest and recreation.

Interesting. I’m hoping Discovery eventually establishes what constitutes “maximum warp” in the 32nd Century. The highest warp factor I’m aware of is Warp 13 in All Good Things, which was just a few decades after TNG. That SHOULD be the standard in Picard now, but I don’t think they’ve brought it up.

Then there’s also transwarp.

I was waiting for Wil to comment about Kovich “3 hour tour”…. So funny, but a line which would only resonate w those of us who watched the original Trek series “originally” … then watched “Gilligans Island” ~ the series with a misfit crew n passengers who were shipwrecked on an island…. from what was to be a “3-hour tour… “ as we know from the theme song which sticks in your head like the Andy Griffith whistle.

Thanks to the writers for that line to give my generation a grin! It was perfect!
