Reposted from dead thread
Yeah okay but I'm not talking about actual MORMONS dude. Like, I'm not even necessarily talking about a religious group. There just needs to be a population of people living in orbital habitats that pool their money and buy an orbital habitat to live in together which all share the same general life ideals of "I want to have like 5 kids". Kids growing up on that orbital will inherit their parent's way of life for the most part, pessimistically 60% of them anyway. With a starting population of 10,000 people, 5 kids per couple on average, and a 60% ideological retention rate, the population of this "space-mormon" group grows to 25,000 people the first generation (say 25 years), 62,500 people after 50 years, 390,625 after 100 years, 95.367 million after 250 years, 9.1x10^11 people after 500 years. That's already entering the beginnings of dyson swarm territory. Also keep in mind that every generation is losing 40% of its numbers to literally any other lifestyle (ie I only want 1 kid, I don't want kids, I want to play MTG, etc), so the actual human population at this point would be even larger.

Well you're taking the gravitational force between two objects, then subtracting centripetal force on the smaller object. Now if the equation was written in terms of F without sin and y that would simply be the gravitational force on the smaller object accounting for centripetal acceleration.

The formula gives you the angle with respect to the horizon that a rocket (usually a second or third stage that has reached the target apoapsis or planned periapsis, OR has reached a target vertical speed) needs to keep to mantain 0 vertical acceleration. Naturally it changes as the tangential velocity increases.
It can be easily modified to keep vertical accelerations other than 0.

inbreeding is a meme, you can fix it by making sure every woman has at least 10 kids. If you build up a large population and just don't allow the individuals that show deleterious alleles to breed, those deleterious alleles will be filtered out of the population. Basically you'll go through a teething period where only one or two children of every batch can have healthy kids, and once you come out the other side you could literally have ten generations of brothers marrying their sisters with no ill effects. We'd basically be cheetas at that point, where everyone can donate blood and tissue to anyone else, no more organ rejection, etc etc, but the whole population becomes vulnerable to major impact from disease (imagine if everyone had the same immune system and it happened to be the configuration that lands you in the "covid-19 will kill me" zone).

if I can find the time I want to take images of the landing and pair them with equivalent heights on earth. Fortunately the lady commentating was giving on-the-fly altitude callouts.

Pic related is only ~10KM above the surface. I think part of the reason the landing is confusing is that people (including myself) expected the rover to be far higher than that since it was approaching from space. But once visual of the ground is obtained it's really quite close. Most of the decent is done with the heatshield on.

Yeah it makes more sense to me that they'd keep the engines in a climate controlled shed next to their factory and just send a few to Boca every time they need them. Raptor is robust enough to spend a few weeks under a Starship in the elements but it'd be stupid to move all the enigines to the launch site right as they come off the pad.

Adding to this I just realized how brutal the K-T extinction event must have been to wipe out all the non-avian dinosaurs when we know that a single breeding pair could produce dozens of eggs in a single clutch. If literally any of the dinosaurs weren't outright killed by the comet strike and its immediate effects, their populations had still been annihilated so hard that not even that level of reproductive fertility could allow them to bounce back. You would think that at least one species of small herbivorous therapod would have clung on long enough in some small corner somewhere to produce a fossil record, before eventually going extinct due to selection pressures from the rapidly evolving mammals.

Zubrin will live at least 10 more years in Elon time
10 years is not optimistic for Starship landing the first crew of 8 people on Mars and returning them to Earth. It's optimistic for seeing fleets of Starships departing for Mars with 40 people aboard each spacecraft and large scale ISRU on the planet, I'll give you that for free. Starship taking more than a decade to get humans to Mars is definitely a pessimistic estimate at this point, don't forget that in between every Mars launch window Starship will be flying hundreds and even thousands of missions to LEO, GTO, GEO, highly-elliptical Earth orbits for interplanetary payload dropoff, the Moon, unmanned to NEOs, and unmanned to other planets, not to mention the previous two or three launch windows will likely see at least several Mars landings by unmanned Starships (with the landing preceding the manned mission involving as many as a dozen Starships packed with cargo n' sheeit)

Have you considered the possibility that Starship might just...not work? So far it's still only on paper, what would happen if an unforeseen engineering problem pushes it back two or three years simply because of a design flaw? Elon's crew is pretty good, but they're not beyond failures.

With Starship? But that part is easy, they already have plenty of experience routinely reaching orbit with Falcon 9, and Starship uses propellants much closer to each other in temperature. The first part of the hard part is reliably doing reentry and landing with Starship, and the second part is doing that in a way that can be rapidly repeated. Actually going to orbit is gonna wait until after they nail the landing, and it'll likely work on the first try. Maybe the return from orbit won't go perfectly first try, I'll admit.

Yup. Combination of low delta V requirements making SSTO feasible, plus thick and extremely tall atmosphere which is basically ideal for offsetting the drawbacks of an altitude compensating nozzle. With that being said, it would still make sense to mount a set of air breathing jet turbine engines (which were supplied with fuel and oxidizer internally and just used the air for reaction mass) to perform most of the initial climb out of Titan's lower atmosphere, only needing the aerospike for the final 3/4ths of the burn to orbit, given that Titan's gravity is very low (local TWR for all engines is improved) and air breathing jets can easily be 100 times more efficient than the best chemical rockets, with some achieving over 150,000 Isp.

We're closer than you think. The interface technology will be designed by artificial agents, who will be designed by other artifical agents who will be designed by us. Soon in the future we're going to wield technology where we quite literally do not understand the more intricate points of how it works. Side note, I also didn't make this spacecraft a "2283" model because there would have been an intelligence explosion by then and the resulting agent would have killed us all.

Think of it like this. To build a Mars colony you bury modules in the desert and make concrete/proont/whatever. But either way that’s really it you just have to keep expanding. With an O’Neil cylinder you have to bring an asteroid which weighs hundreds of thousands of tons to a “useful orbit” which is already an insane feat, and then you have to use advanced in space 3D printing which doesn’t exist yet. But I’m most concerned about the face that orbiting colonies have very finite numbers of resources. This is not “The Expanse.” Even our best modern day tech is slow as shit when it comes to interplanetary travel. Worse, you can barely move anything.

Based idea bro. I’ve always wanted a SciFi universe that’s set after stuff like “The Martian” but before “The Expanse.” You know, like how there’s thousands of people on the moon, mars, maybe a few near earth asteroids, but the outer planets are still an untouched wilderness. The only thing I can think of being in this category is something like “Ad Astra,” where Mars colonies have been around for about 30-40 years but we still have yet to send colonists beyond the inner solar system.

Okay, let's look at the builders of the cylinder. How do they profit from doing it? What resources or power do they gain? Rent from inhabitants? How do those people get their living? The void is cruel, there's nothing there. I love space habitats as much as the next guy but planetary surfaces are where it's at. There's simply not nothing on planets and moons and stuff.

Also look at this concept I came up with for a rotating habitat anyway. The walls and ceiling are light field displays so it looks like bright clear skies as far as the eye can see in all directions. You even get a "sun" indistinguishable from the real one and a 24-hour natural day night cycle complete with sunsets. Moving parts are the devil so landing is accomplished on inner surface runways and the whole thibg is thermoregulated via Einstein refrigerators hooked up to goliath heat pipes.

Ad Astra was meh to me I enjoyed the visuals and spaceflight aspect but the science was crap. Still I really liked the setting and I thought it was Kino at times. Anyhow seriously a series set 30 years after the first mars colonies were started would be amazing. Mars would be too young to be an independent world but there would still be vast wilderness on it. The asteroid belt would be ripe for picking except no one has fusion drives yet so it’s off limits. And the gas giants are still untouched aside from one or two “flags and footprints” missions to Ganymede.

A station like that would be there to house a city of personnel and their families to do certain tasks like maintaining the magnetosphere generator that protects them and Mars's atmosphere that said station is attached to. It would be a company space city in practical usage
Building miniature O'Neill cylinders to be the core of a colony ship for when interstellar probes find habitable or easily terraformable worlds and want to strike it out in another system is another reason to do so as it'll be that with a reliable breeder reactor, some armor, a shuttle dock and a plasma sail/ propulsion engine, and probably some generalist wildlife embryos for a DIY ecosystem

The only justification you gave there for a "static" habitat is for an Earth-Mars L1 magnetosphere generator. That's a machine which forms a cornerstone of the goal of true terraforming. From a simple engineering perspective, if you want your generator to protect Mars for eons or longer you will wise up to the fact that people are way too volatile. When you need an entire planet to breathe for an indefinite amount of time, putting a bunch of violent hairless apes on board will not help the situation. Long before we begin thinking about terraforming there will come a time when we invent machines whose general problem skills mean they can keep themselves repaired given proper energy and resources. Don't you think we'd be better off to leave the job to those machines?

Also Titan lacks things like metals, so ISRU of anything but fuel or water or air is going to be hell.

That we must have 1 G is unsubstantiated and there's no way to assert one side or the other. All we know is that 0 G is really bad.
