What is your personal head canon?

There's another advantage to having the ore processing done in orbit... Cardassian ships receiving the ore are far less likely to be attacked at the station than if they landed on the surface. (Or shuttles carrying the ore.)
Possibly the ore was mines in space and transported to the orbital station for processing and then transported to Cardassia Prime.

I note that when Jake was teaching Nog to read, Nog read from something which said that Bajor had three moons.

But Jerrado, the large habitable moon, was said to be the fifth moon of Bajor.

And one possible theory it that Bajor had a few large natural moons, and the Bajorans also sometimes moved small asteroids into orbit around Bajor to mine them. And maybe during the Cardassian rule of Bajor the cardassions moved small asteroids into orbit to mine them. And they took the ore to the orbital space station to be processed, and then the ore was shipped to Cardassia. And by never taking the ore down to Bajor and then back up into space, the Cardassians saved a lot of energy and money.

And possibly the Bajorans and later the Cardassians would take an asteroid moved into orbit around Bajor totally to pieces when mining it. Thus the number of moons which Bajor had would fluctuate over time.

And why would the Bajorans and Cardassians mine asteroids in the Bajor system for ores instead of mining Bajor itself?

How long has Bajor been civilized, and was that longer than the time it would take to mine all the good and easily accessible ores on Bajor, thus making mining of hypothetical Bajoran asteroids the logical course of action?
 
You literally did. It was one of your what-ifs.

I literally did not, and it was not.

If escape velocity is 3X Earth's, does that not me surface G is 3X Earth's?

No. They're related, but they aren't the same. You can think of the escape velocity as more like the concentration or density of a body's gravitational field. Escape velocity depends on the square root of the ratio of a body's mass and radius; surface gravity depends on the ratio of a planet's mass to the square of its radius.

For example: in our own solar system, Venus and Uranus have almost exactly the same surface gravity – 8.87m/s² – but Venus, being much physically smaller and denser than Uranus while also weighing significantly less, has an escape velocity of 10.4km/s, whereas Uranus has an escape velocity of around double this at 21.3km/s.

Don't you have to factor in the density / composition of the atmosphere and how it's drag affects the vehicle launching off the planet trying to escape?

Not really. The escape velocity for Earth is 11.186 km/s (40,270 km/h; 25,020 mph), which would be nearly Mach 38 at sea level. You're not getting to that speed inside the atmosphere. But the difference in distance from the center of the planet to the surface vs in "space" is not great enough to change the numbers by much. Every launch today has to get outside the atmosphere first before it can really put on the speed to stay in orbit or escape the planet entirely. By the time you're up to 11.186 km/s, you're already way outside the atmosphere.
 
Good evening from Germany, I hope you all are okay.
In my head-canon, the three big shows "Earth - final conflict", "Star Trek" and "Andromeda" could've told a complete story, how humanity and aliens interact. EFC could have taken place on a post-first-contact-world, maybe one could've told stories about how post 3rd World War Humanity was not evolved enough to understand these aliens, so one could've told the story of Humanity being on its lowest point and yet the vulcans are helping them.

Then the whole Star Trek - Franchise happened and now one has to say, that everything after Season 2 of Star Trek: Discovery basically is Andromeda.
 
I guess this could go under either “headcanon” or “controversial opinion”:

While the Burn and the period after it are seen as a “dystopian turn” by many, that’s got to depend on where you were when it happened. After the initial tragedy of all the lost ships and lost contact between distant systems, planets that already had established, self-sufficient (or self-sufficiency-capable) post-scarcity infrastructures — Earth or Vulcan, for example — mostly did just fine. While United Earth apparently swatted away desperate raiders from Titan, life on Earth itself mostly continued with much the same quality of life which had existed during its Federation membership. (Why Titan didn’t have a similar sustainable post-scarcity setup is an open question. Perhaps Titan had never actually been colonized, and the group that became the seed of Titan’s population began as the crew of a stranded ship or small installation?)

And it would be easier to load and unload those ships if they're in orbit.

Landing a spaceship, even an ore carrier, is always awkward. Much easier to keep them in space as long as possible.
 
BTW, I put the "Why ore processing in space?" question to DS9 writer Robert Hewitt Wolfe on Bluesky and this is what he had to say...

Shoot, one of those explanations that hits like, "I should have considered that."

:rommie:
 
I hope I don't get banned after this...

Okay so I love the movie First Contact, I really do. But up until that point nowhere in Trek was it ever mentioned Humanity's FC was with the Vulcans.
In fact, the TNG episode with the same name mentioned more about Klingon first contact than Vulcan first contact.
My headcanon: humanity reached the stars as they did with Cochrane's warp drive, everyone else were using whatever propulsion method, but warp became the easiest solution compared to all and that's why Cochrane was so famous.

But the Borg mucked it all up, and everyone's memory through some quantum explanation became whatever it was in FC cuz that created a new timeline, but the TNG crew had zero idea cuz from that point their own history changed.
So now Riker gets to be onboard a holonovel aboard the NX-01 and we fans have had to cope with that ending to ENT for 20 years.

That wasn't humanity's first contact with any aliens. It was regarding first contact with the Klingons, specifically.

Before ST:FC, NOWHERE in canon was it ever said which alien race was the first ever to contact Earth. Thus, FC was free to say it was the Vulcans, without any disruption to continuity.

You know what, you're completely right. I am just very nitpicky about these things, a personal fault of mine that I take full responsibility for.
It's like Frontier Day for PIC S3. Nobody gave a flying eff about such an important day, but after ENT everyone suddenly remembers the 6th Enterprise :p
 
So when it's it's still a mystery which aliens came first to earth, isn't this stuff for upcoming Star Trek series or movies to solve it?
Probably more interesting than Section 31 ;)
 
In the novel "Strangers from the Sky" humanity's first contact with aliens is a secret encounter with Vulcans. This is covered up because it's felt humanity isn't ready to learn of such drastically different aliens. Instead, the "official" story is that the first alien civilization humans encountered were the very human looking inhabitants of Alpha Centauri.

I have that novel. Actually, I have it twice. One version as a solo-book and the other one as part of a trilogy, dealing with Star Trek-things, happening before TOS, e.g. Kirks Dad is the security-officer aboard the enterprise.
