I'd figure that but you'd think they'd aim a little higher since they're using methane and get a few percent higher Isp by default anyway. I guess that means we can comfortably draw up the target specs for BE-4 as being >311 sea level Isp at 2400 kN thrust, compared to ~230 Isp at ~2000 kN thrust for Raptor. If BE-4 shares a similar sea level to vacuum Isp relationship as RD-180, then it'd have something like 340 Isp in vacuum, compared to Merlin 1 D Vac's 348 Isp, SL Raptor's ~355 Isp, and Raptor Vac's Isp of ~380.

Nah, sea level Raptor is 2000 kN at 330 Isp, in vacuum the same engine hits ~355 Isp and correspondingly higher thrust that I'm not bothering to calculate, and the vacuum version of Raptor hits ~380 Isp (obviously when in vacuum, because at sea level its Isp is zero since it would explode if you fired it)

Senator of Alabama. Head of the pro-SLS lobby. Is strongly against anything in American spaceflight that can be a threat to SLS. Apparently propellant depots were a threat, maybe because they would allow for smaller launchers rather than the ultra heavy SLS.

He's an ass. He cut the budget to the commercial crew program, and then threated to cut the budget further when the program inevitably fell behind. He doesn't really care about spaceflight.

It probably won't be a thing tho, instead the population and usage of resources by each member of the population will rise until they reach equilibrium with supply, and what things are scarce will also change.

Orion was designed for the constellation program. Mission architecture there was that the Altair lander, a huge motherfucker launched on Ares V, would do the braking burn into low lunar orbit

well we don't have Altair anymore, or Ares V, and Orion doesn't have the delta-V to go to low lunar orbit and back

so instead we need a small space station in an intermediate halo orbit. Orion can get there and back, and the crew can transfer to a lander there. tentative design is a three stage lander where the first stage transfers from halo orbit to low orbit and back again

yeah maybe it would be better if Orion didn't suck, but you go to war with the army you have

Why bother with Sea Dragon when they can incrementally improve Starship Super Heavy and the Raptor engines until they start hitting ITS performance targets? It's significantly less risky and offers even better cost/kg performance than Sea Dragon, with a vehicle capable of placing 300 tons into LEO in reusable mode and 550 tons in expendable mode (which it never would operate in, but it gives a sense of scale).

Note that it wouldn't be iteration like the upgrades to Falcon 9, they would eventually need to increase the diameter of the tanks etc to make room for more engines, but the Raptors they have now at the performance levels they think they're gonna hit would be perfectly adequate to make an ITS-class reusable rocket once they increase the diameter to 12 or 13 meters. Also note that they're proving right now that they can prototype Super-Starship without needing to order any tooling, by using simple jiggs and welding steel together in a field. Also, once they transition current 9m Starship to being produced using actual tooling for more consistent complex structures, they can order that tooling set to be expandable up well beyond 9 meters diameter if they want (even their current Falcon 9 tooling has some diameter range settings built in, though they only use it at a single diameter regardless).

Yes, but they can build a 12 meter or wider prototype quickly and cheaply if they want, once 9 meter Starship is flying and making money.

I just saw that video. Makes me wonder if he's the anti-SpaceX FUD poster here. Sure, we should be skeptical of reusability after the false promises of the Shuttle, but some of the issues he brings up are either misunderstandings or just false. There are legitimate points against SpaceX and some of their promises, but he just seems to be more interested in shitting on SpaceX because he wants to be a contrarian.

I'll just bring up one point of his
>"..they're struggling to replicate the [Apollo] command module." [16:29]
No, SpaceX has made a nice usable capsule, but they had an issue during testing. The Apollo capsule had a rather disastrous first test too if I recall correctly. Testing is supposed to look out for such problems. Should SpaceX forego testing and only do studies until they were absolutely sure that things would work flawlessly? No, because no amount of studying will prepare for the real thing and one can encounter the real thing in a controlled way through testing, let SpaceX blow up stuff during testing as long as they show a commitment to improve.

Sometimes I want to make videos explaining spaceflight for people who aren't knowledgeable about it due to the fact that I explain it so much already with friends and family, but I kinda get imtimidated by the likes of Scott Manley or Paul Shillito in that I doubt I can match their quality. However, thunderblunder here has probably set the bar to be so low that it's subterranean, so maybe I should give that a shot.

Nice pun.
But that's the beauty of going big, no need to optimize mass down to the last gram. No need to grind down washers or bolt heads. No need to omit features such as toilets to save mass. No need to rely on highly specialized expensive lightweight materials. All that allows for speedier and more flexible development.

I'm not sure if poop can be made magnetic, but I can imagine maybe heating it to make it decompose. The released gasses can self-pressurize themselves which then can be used as a simple thruster. I'd do the calculations, but I don't know enough about waste for the modeling to not be shitty.

Unless you grow all your food onboard (which would imply a very, very large habitation platform indeed) you'll always have additional carbon entering the system in the form of food imports.

I'd like to hear about kangaroos also, and can back up your tales of stupid deer.
There's a bunch in the patch of woods near my house, so sometimes at night you can hear them click-clacking down the road. Last year I spent a bunch of time in the woods, and after half an hour or so they'd stop being afraid and start just walking around munching on stuff while I worked. They'd never get closer than fifty yards or so, but it was still neat to see them not be panicky dumb food. You can yell at them too and they just look up at you with this retarded look to see if you're trying to eat it or not.

for Mars you need it because NASA's plan is to use solar electric propulsion for the Mars transfer vehicle

thrust for electric propulsion is really low so if they launched from LEO manned they'd spend too long in the Van Allen belts

so instead it'll go to the gateway unmanned, then Orion brings crew to the gateway (passing through the belts quickly), then crew transfers to the deep space vehicle and goes to Mars.

everything about the gateway is dumb but not as dumb as it initially looks

It's dumber than that, because SEP will get you to Mars more slowly than chemical engines, despite the higher delta V it can provide, simply because it takes so long to apply that delta v in comparison. Current electric propulsion doesn't get you anywhere faster than chemical engines until you start looking out a bit beyond Jupiter IIRC, I'd have to do math to know for sure on that one tho so fuck that.

Because if it weren't in a rectilinear halo orbit next to the Moon there would be commercial competition with SLS for getting it built. That's literally the reason, it's also why each additional LOP-G module is meant to be launched with an Orion, it's not for any real reason beyond the fact that mandating Orion means they've mandated the whole thing launch on SLS.

I think he meant that for the effort of launching a SEP unit to the Moon, then a spacecraft to the Moon to dock with it, then leave, you can just launch the SEP unit and the spaceship into LEO and boost them away from Earth chemically, for actually less effort in terms of mass and mission complexity. Wasting time departing the Earth-Moon system using SEP doesn't make sense when you can leave and get started accelerating in reference to the Sun and thus arrive much sooner.

of course, but if you're using chemical engines you'd need to launch way more mass, you'd need about ten launches to refuel the thing in LEO before it could do the Mars transfer. SLS is too expensive for that, and it will fly at such a low cadence that the propellant you're launching will boil away before the next refueling flight

you'd need some kind of rapidly reusable super heavy launch vehicle to do a mission architecture that can get a manned flight to Mars on chemical engines. Without that it's either solar electric (current NASA design reference mission), nuclear electric (old Russian mission concepts), or nuclear thermal (old NASA concept).

I'm gonna stop reading RIGHT THERE and reiterate that I only meant using enough chemical fuel to boost away from Earth to interplanetary space, which is actually *less* than what you need to get to, and slow down to stay at, the orbit that LOP-G will be sitting at. From there on, it'd be all SEP. Now I'm going to read whatever else you wrote

Yeah, basically I think you misunderstood what I was trying to explain. Also the solution to boil-off is to use storable propellants for the escape burn stage, launch it empty or mostly empty and with every subsequent module launched to LEO bring along a gas tank with a few dozen tons of propellant to use up that payload mass capacity. Also I should point out that this is simply what could be done more effectively with SLS hardware, which does not reflect the reality of the situation in which any introduction of the possibility of SLS having to compete with anything else gets ignored or defunded. I'm not suggesting NASA is gonna do this, because there's no way shelby would allow it. The reason of course is Falcon Heavy, because if you're doing a SEP interplanetary vehicle in LEO that departs using a chemical booster stage refueled in multiple flights, you buy Falcon Heavy, not SLS.

>mission-ready parking orbit
Sure, depends on the mission and the orbit tho. For example I think there's a plan to get a trio of high-speed flyby probes with kick stages into a high Earth orbit (or was it one in Earth-Sun L2, one at L5 and one at L4?) to wait until the next time we detect an interstellar object coming into the inner solar system, at which point one or more of them would light off their kick stages and get in the right place at the right time to snap closeup photos and take readings. That makes perfect sense, because the spacecraft aren't just built and sitting in a climate controlled vault somewhere waiting for the signal to scramble for a launch, they're already launched and just kept dormant and ready to go. As for stations in proximity orbits around objects of interest for manned missions, ehh. Unless those stations are propellant depots supplied from the object down below, locking your activity into a certain inclination (even a polar one) is generally far more of a hindrance than any possible benefit can counterbalance, unless that station is actually a terminal on a space elevator or something like that.

Fish and algae will be the first things, fish to provide meat food as well as recycle hydroponics waste like worm castings and other nutrients. Algae to provide dried pellets for fish food as well as plastic and various oil production, algae are especially good since unlike plants they don't give a fuck about radiation or light levels so you can grow them in big tubes on the surface with minimal energy input, heck those tubes could also function as radiators for waste heat. Shrimps and other small crustaceans could also feed off the algae and grow in these tubes.

Next would be fowl since they are small if you are transporting then full size and I'm pretty sure the embryos can be cold stored but I'm not 100% on that. Fowl can also be fed on your algae pellets and their poop is great fertiliser, rich in nutrients.

That's probably all there will be for a long time, large fauna is extremely intensive in space, food, time and care required.

That's exactly what I was thinking of when I proposed that idea. Just launch ahead of time when the weather was nice, and then there's no risk of weather ruining a mission because it scrubbed a launch that had to go directly to a transfer window. It can work for manned missions too (without the stations) just with a much shorter wait time.

This is one of the biggest problems with a Mars colony, it has to be sterile as fuck, a crop blight could potentially wipe out all their food and if they dont have enough reserves everyone is dead. Similar with viruses and bacteria, especially as time goes on, the 6 month mildly irradiated environment should serve as a good isolation environment for this but Martian children will be especially vulnerable, having never been exposed to all the filth and shit in Earth.

The solution is not to sterilize, which is impossible since humans have gt bacteria and skin bacteria, but rather to make the Mars colony interior a breeding ground for soil bacteria. Have potted plants and soil-containing gardens fucking everywhere, live as a slob, expose yourself to as much in the way of bacteria and viruses as possible at all times, and keep a strong immune system as a result, even for future generations.

The solution is to spray a fiberglass/resin layer around the base to lock down the regolith, and have a suit switchover station at the edge of the dust exclusion zone.

Excursion suits would be suitport-style and never actually go inside a structure, and the changeover to hab-operations suits would happen inside so that they have no real opportunity to interact with the dust.

the idea of a vacuum engine is that the pressure of the exhaust at the end of the nozzle is as close to zero as possible, which in practical terms means that the exhaust forms as cohesive of a beam as possible
you want that thing coming out like a fucking laser, but unfortunately that requires an infinitely long nozzle, which is stupid
somebody's done the math on nozzle length (isp) vs weight tradeoffs and there's an optimal for every dry and wet weight, but you just kind of pick one and go with it
anyway, it comes out super cohesive and at less than atmospheric pressure, so it gets squeezed by the atmospheric pressure pushing in on the sides, and eventually it gets squeezed enough that air starts to push its way up the nozzle walls, which invariably doesn't happen consistently and then the nozzle goes boom
you can see this start to happen during SSME startup, let me go find a video

Overexpansion. The pressure in the exhaust jet is much lower than atmospheric ambient and air intrudes into the engine bell, causing the jet to vibrate back and forth, which can destroy the engine.

https://www.youtube.com/watch?v=hDCCBgppG4s

You can see it here with the SSMEs. Also, look on the inner wall just as the exhaust is ramping up to full power and it switches from orange flames to clear-blue: You'll notice "ripples" crawling up the walls of the nozzle. that slowly move down as the engine achieves full power. That's what im talking about, the air intrusion. The SSMEs got away with it because they were externally reinforced, and the engine bells changed their angle near the edge so that they expanded more slowly to help get some control over it.

This.

That trend will hold true even if human civilization consists of 100 quadrillion people living in an extended Dyson swarm, with fragments of the population measured in billions of individuals collecting together with a common interest and splintering off with their hundreds of thousands of space habitats to go colonize other stars in a manner analogous to how a dozen people on Earth today may meet on social media and decide to go trekking and camping for a few months.

I haven't read or watched anything about the Expanse, but what I can tell you is that in real life where narratives can and often are boring, if we developed any kind of self sustaining industry beyond Earth's gravity well we'd very shortly after see that industrial capability start exponentially growing, and once that happens the solar system gets blown wide open for colonization, even without advanced propulsion systems. It'd be pretty much impossible for any government on Earth to oppress any industrially capable human presence on Mars, unless they deliberately withheld things that the Mars people couldn't just develop the capability to produce on their own. The only example I can even think of there would be organisms, like insects, fish, plants, whatever, to serve as foodstuff. However, for the Mars colonies to not have had those already before relationships turned sour would mean that these colonies depended 100% on food deliveries from Earth, and furthermore that none of those foods contained any intact DNA samples from the organisms they came from. Everything else, from nuclear fuel to silicon to exotic solvents to metals and so on, can all in principal be re-developed on Mars, provided they have the right seed industry to grow these other manufacturing capabilities.

I think the point at which human civilization will really kick into high gear in terms of spreading throughout the solar system will be the point at which we colonize Ceres, likely helped by equipment and resources sent from Mars, and use the Ceres colonies as a means of spreading to every asteroid that comes close to Ceres at low velocity due to orbital mechanics. You think Starship is a shit box? Wait till you see what asteroid jockeys based from Ceres will be riding, since the accelerations and delta V requirements are so low you could literally get vehicles welded together by one guy with shaky hands that would still be useful for hopping from rock to rock.

That might be the endgoal but can't see that being true at any point during my productive life.

I'm 26 now, let's say that figure becomes true in 40 years. Are they realistically going to send 66 year olds to Mars en-masse? And then what am I going to do when I get there? Manual labour? Doesn't make sense.

It really depends on the scale of the manned presence there. You might be right if the most we do is an Antarctica-style science outpost, but if it's a colony of any size at all I'd say your chances are decent. Past a certain threshold, extra hands become more of an asset than a burden, so anybody in decent shape mentally and physically will be welcome.

'They' aren't going to send anyone, it will be people who want to go and who can afford a ticket, just like air travel. What you do when you get there is your problem. If you can't figure anything out, someone will find you something to do, and if you still aren't being productive, the flights back to Earth are free.

If permanent habitation beyond earth's orbit takes off, it'll be pretty interesting because it will offer a promise of purpose that has become difficult to attain on Earth. Here a janitor is just a janitor and a line cook is just a line cook, but on Mars or wherever else you're a crucial piece of keeping the settlement livable and in a condition where it's able to grow.

I assume you mean that spaceflight would have moved on from LEO and that no one had considered a LEO space station again due to the focus on bigger things. I hope you meant that rather than the more disturbing thought that spaceflight would regress so much that even a LEO station hasn't been possible.
