). I wouldn't be surprised if the Roci can thrust as hard backwards as forwards—just with much less efficiency (no impossibly efficient Epstein drive).

When Adam Savage did a behind the scenes on the Roci, it was mentioned that the seats can recline to different positions depending on what kind of acceleration they are doing.

Been a while I've read the books, but weren't the crash couches fully articulated? I figure that'd be too much complexity to implement for a TV show.

It seems like 1g of acceleration is plenty to get you where you're going very fast. In fact holding 1g for the whole trip is quite impressive. I guess it makes sense for emergency combat maneuvers and poo poo, but your average civilian vessel probably doesn't need to ever accelerate to the point of needing "crash couches"

My impression from the books is 1/3 g seems to be the standard not in a rush acceleration, though maybe that's just Belters.

1g will get you to Pluto (at its closest) in just over a week. So if you can do 1g of acceleration indefinitely, the solar system is yours. Hell, if we had a breakthrough that allowed that kind of acceleration today, the rest of our tech is sufficient enough to allow us to pretty much do manned exploration of most of the solar system.

Belters seem to prefer even less acceleration if they can get away with it, but 1/3g does appear to be a pretty standard rate. I think it's partly a compromise, since the spinning stations like Ceres and Tycho are at 1/3g, and partly because fuel consumption and heat buildup make greater sustained acceleration impractical.

They can't be doing regular constant 1g then, they talk about how Uranus and beyond are far enough journeys that there isn't much activity out there. Couple science stations like Antarctica today but that's it. Real human habitation ends at Saturn.

Maybe the other reason for this is that the planets beyond Mars, with the exception of Pluto, are all gas giants not suited for landing. And that the planets beyond Saturn probably don't have interesting moons to colonize. Being so much farther away from the Sun would also limit the desirability to colonize such a location.

If you could get out there easily you'd think the ice haulers would do it though. I guess Saturn's rings have plenty for the foreseeable future.

Crash couches vary depending on what they do. The one in Naomi's room that Holden and her banged on before being rudely interrupted by 3-4 hilariously bonebreaking gs, you could sleep in over long stays, basically flat. The ones in cockpits, I really don't know why, I picture like on the show, skinny lay-z-boys with articulated arms with controls and poo poo at the hands. 1/3 g is standard because it's comfy. To earthers, you're floating on a cloud of titties but your reflexes still kinda count, unlike 1/6th.To belters, it's just normal, a full G in any spinning habitat other than the gigantic would mean corliosis that got truly weird, beyond just making you feel sick, which belters I figure are basically immune to. I used to get carsick. Then I read a book over a 6-hour drive when I was 10. I was already sick, I'd been carsick before and I knew I had 3-4 hours of being sick to go, we were an hour in, might as well be entertained and carsick instead of bored and carsick, so I read and breathed heavily and read and put the book right up to my eyes when it got blurry and read some more and tried to get to a part I could mull over while breathing heavily out the window when I couldn't get the words anymore. Ever since that trip, I can read all I want. Never been carsick since. Being acceptable to everyone, it's the natural standard. The most unbelievable thing is that there would be a standard at all. This is all headcanon poo poo, but it makes sense to me. As far as I can tell, the space poo poo in Expanse is believable. Even the juice. Get 1-2 chemical processes right that break down in high-g, salt the veins and arteries, make them stronger and less elastic without killing you, with an as-yet undiscovered counter-agent ... yeah, I buy it. And that's the real test, right? Does it take you out of the story? If no, it's a great goddamn sci-fi thing.

Well, i mean, they have anti cancer meds that break down any cells that replicate too quickly. So the anti g drugs never bothered me. I also get that they have large amounts of anti nausea meds on hand to fix those kinds of issues. And I don't mean Dramamine.

Yes but then you’re pushing everyone into the floor again, so no need for omnidirectional crash couches. I’m suggesting that corvettes like the Tachi feature enough RCS to reduce closing speed at 1 g or more while keeping the nose pointed at the enemy. Probably not enough acceleration to kill the crew, though, which the Epstein drive is certainly capable of.

I'm not sure myself, but I'm guessing it's less weight to help keep your mass planted. Ever been in a swimming pool and tried to kick off real hard from the floor, the same way you might do a quick sprint on the ground? And I don't mean the water slowing you down, just less traction I guess. Like a really light car with a lot of power. I'm sort of picturing Newton's Laws being amplified, like if you spun around really fast it would be harder to stop yourself. I'm sure someone will explain it soon.

I think they meant that, for someone used to substantial gravity, 1/3g is enough that your intuitions about motion more or less still apply. There's a definite up and down, you can basically walk around normally, etc.

Apollo astronauts reported it was tough to work in. Like you can't even walk properly in 1/6, that's why they're always doing that weird hopping motion instead since it works a lot better. Some of their clumsiness was the suits but some is the low gravity. All that said I imagine if you were born on the moon you'd have no issues. Mars gravity is generally assumed to be sufficient for people to function normally though.

Always funny to watch scifi astronauts move super slowly as if they were swimming in jelly. I understand sudden movements could be risky because action = reaction, but they overdo it on TV. I really like it though in the series that Earth people are significantly stronger than (untrained) Martians and Belters. Another cool bit was the guy removing his helmet visor in hard vacuum and actually not have his eyes explode. (PS : where are those rocks headed? is that a book spoiler?)

"Harass" is a pretty generous interpretation of that scene. The Martian patrol ship essentially sentenced them to death.

That plays out completely differently in the book. There, the ship is jointly owned by several Chinese families (hence the name: Xinglong) who were behind on their loans and disabled the ship's transponder so their bank couldn't repossess the ship. But they came too close to a Martian warship who blew them up (possibly without a warning). Cue even more unrest in the Belt. That's also what leads to a random Martian guy (not Miller's partner) getting tortured and nailed to a wall.

Oh yeah, the Martians did something that resulted in the Belters not having enough air or water, right? The recap I skimmed to double-check where the rocks went only mentioned the Martians impounding cargo.

The Martians denied them passage through the section of space they were patrolling and the Belters didn't have the air/water to survive going the long way around.

You then see on a news broadcast in the background of a scene the reporting of the incident as an act of OPA terrorism towards Mars, which leads to the crackdown on ships flying through Martian space which leads to the events of Donkey Balls.

Martian marines do spend time training at 1g, for what it's worth. As for the terraforming, I'd be more worried about all the perchlorates in the regolith. You can always burn up more comets in the atmosphere if you need to, but that doesn't matter much if the place is covered in poison.

I think a lot of the info on how horrible mars is and totally unsuitable for anything beyond a science outpost is mildly new and maybe when the books were written people still had crazy ideas of "colonizing" mars. Then again colonizing incredibly hostile planets instead of just building space tubes is a pretty established scify trope and scientific blind spot in like 99% of scify.
