Did the rocketman give projection of how much he hopes to decrease launch costs per kg? How much he thinks he can pull off?

>>12092725
$15/kg isn't it?

Early Apollo lander?

Imagine how big a deep space probe kick stage you could make with Cargo Starship.
>50 ton probe packed full of cameras, sensors, and RTGs
>pair of 50 ton kick stages
>full five-kickstage Orbital Yeet Train just takes two reusable Starships ($4M in launch costs)
>add another six kick stages ($8M total launch costs) and you can enter into orbit around any planet in the system

>>12092752
It's an ideal but it's still in the realm of possibility considering how cheap everything is getting

>>12092761
I'm struggling to find the original source of that image, but I think it's a model of the Apollo direct ascent lander. The legs and contours between the two look similar.

Reminder:
>NASA's new Space Launch System (SLS) megarocket and associated ground infrastructure have soared past original cost estimates to a degree that requires the agency to notify Congress about the ballooning budget.
>"The new development baseline cost for SLS is $9.1 billion, and the commitment for the initial ground-systems capability to support the [rocket's first] mission is now $2.4 billion," Lueders wrote, without elaborating on what the previous baseline costs were. Congress had previously approved a $7 billion commitment for the SLS' development, according to 2019 fiscal numbers.

This game has fucked up my PC.

Since I got it, it was running really high on CPU. To the point it warmed my room 2°C, so I only played it with A/C turned on.

I was going to make a quick game, started the thing, selected my ship, and while it was loading the screen got black and the fans in my rig slowed down. The OS was toasted so I restarted. But the BIOS beeped and it didn't boot (beep codes for GPU error). I disconnected every non-critical USB and internal component and now it is running again, so I suspect undervoltage.

Looks like running so much time on high CPU fucked up my PSU or something. It is a 650 modular, never gave me problems.

I tell you guys, this game has shit optimization, but it is funny as hell, so be aware it can fuck your rig.

>>12092829
>>12092830
I mean even some of the Artemis proposals have huge ladders (national team I think in particular). Rope ladders suck though and would be so much more physically demanding. It’s all semantics though... that 60s proposal was never made and if it were it would probably have a hard ladder build on to the side

>>12092837
The hell are you on about I played it on a fucking Surface and it worked fine. There's something wrong with your rig.

>>12092854
Specs are enough for a 2013 game.
GPU is overkill for this game, but not really relevant, since the game is CPU bound.
CPU is almost 3 GHz, nothing like the new ones, but enough (I tuned down the game settings and it usually peaks at 80-90%).

>Eventually, Congress got the upper hand, putting NASA on track to build the large SLS rocket at a development cost of more than $2 billion a year. The rocket program mostly benefited the Alabama space center and was championed by Alabama State Senator Richard Shelby. The potential of in-space fuel storage and transfer threatened the SLS rocket because it would allow NASA to do some exploration missions with smaller and cheaper rockets. As one source explained at the time, "Senator Shelby called NASA and said if he hears one more word about propellant depots he’s going to cancel the Space Technology program."

The space industry and human survival, which you so nobly talk of, comes from the need for jobs, money and votes. Now take this space launch mandate. Here it is: economic, scientific... boring. But if it is spread across the country.. now look at all these little contractors! So busy now! Notice how each one is useful. A lovely ballet ensues, so full of form and color. Now, think about all those people that created those rocket parts. Technicians, engineers, hundreds of people, who will be able to feed their children tonight and give me votes, so those children can grow up big and strong and have little teeny voting children of their own, and so on and so forth.

I have been doing some digging, and apparently, since it cost about 150 million(brand new) to throw a Falcon Heavy at Mars, and since gold is about 62000 freedom bucks/kg and FH can take 16800 kg of payload with it, then assuming it you find a easily extractable gold depot on Mars, and assuming that trip back home would cost just as much as here on Earth(about $9000 per kg to get to Mars, plus 5400 bucks to reuse the rocket for the way back), then you could actually mine that shit for a profit there.

Probably just little modifications of the basic TSTO design. I imagine by the time New Glenn and Starship are considered "old" like shuttle was in the 00's, there will be new developments. Aerospikes, better heat shield, etc. I predict Aeroass will be made at some point and could be used for 100+ years without modification (until something like reactionless drives are made). Put me in the screenshot when I'm correct 50 years from now.

This is fucking cool. I followed this from the last thread. Are those the landing leg designs from the original ITS design?

How easy is it to find precious metal deposits from orbit?

It seems like one of the main financial rationales to go to Mars will be delicious precious metals and rare earths. Will people have to go around prospecting, or will SpaceX just launch a few prospecting satellites and call it a day?

>>12093517
They are indeed quite similar. Although with ITS they're much higher up so they'd have to be much longer. If I were to rework the design I'd extend the skirt all the way down to the ends of the bells and lower the legs with it so they take up less weight.

>>12093528
You'd probably need geologists.

>>12093533
I wonder if they were intended to be aerodynamic surfaces on the original ITS. They don't look like they can really do anything other than hold the landing legs. But it looks way more stable than the current design that tucks the little legs close to the engine

>>12093528
>>12093580
>You'd probably need geologists.
I'm a geologist who does work like this. It's called remote sensing. You can look for minerals on the surface, but trying to look for stuff deeper from orbit is tricky. You can only penetrate so far with electromagnetic wavelengths. But we have a general idea of where the "good stuff" is on Mars. Pic kinda of related but not really, it's the only thing from my work in my camera roll

>>12093201
magical

>>12093582
I'm not an air doctor but if I had to guess, I'd err on the side of them offering some level of braking benefit simply because they protrude significantly from the sides of the vehicle. By giving it a larger surface area on the bottom they'll help spread out heat from reentry and slow the vehicle down faster.
They wouldn't produce lift though, at most I'd assume they just act to keep it aerodynamically stable, since the vehicle will be falling toward's Earth ass down and the surfaces start wide and narrow to sharp points they'll help both create high drag at the wide part and create supersonic vortexes at the narrow points, further increasing drag.

ITS though is obviously not designed for remotely plane-like reentry, it's essentially a giant capsule and it would slam into the atmosphere hot and fast, and perform a hard deceleration burn to land propulsively.

>>12093595
Any good stuff in Hellas?

>tfw you want to play KSP but you have a two page essay due tonight
bros im not gonna make it!

>>12093602
ITS was absolutely intended for plane-like reentry. The belly flop was part of the architecture from the start.
On this >>12093533 rendering you can see the edge of the belly heat shield up near the nose, and the skirt extension near the bottom to protect the nozzles.

When will someone do a private lunar sample return mission?

Launch and hardware costs have to be low enough now. That it could be financed by a small group of wealthy individuals. Then they auction off most of it to recover costs.

>>12093612
Yeah, my bad, been a while since I actually thought about ITS. I guess in that case the leg projections would also be pretty useful for belly flopping, not only do they significantly increase surface area on the belly but they also make it a sort of "cupped" shape which will help to slow the vehicle more. Still doubt it could glide in any meaningful way, it's still a lot more "bullet-like" than Starship.

SpaceX should hydroform the tank domes. They can form a complex shape ready for trimming and welding. much simpler than and cheaper than a hydraulic press.

>>12093621
They won't be low enough until Starship is operational.

>>12093661
They would need to build a hydroforming machine more than twice the size of any that currently exists, so I'll bet that wouldn't happen until the design is more or less finalized.

>>12093663
Starting bid at $50,000 a gram. 4 kilos of moon could fund a FHeavy expendable based mission.

>>12093661
The largest hydroform I've ever heard of is used for making 6m diameter antenna dishes, and those are aluminum. For steel I'd assume you'd need a substantially higher pressure, plus the mold itself would have to be 30% larger than what I assume is the current largest mold in existence. Like >>12093669 says, that or dish forming might be worth an investment, but only once the gross features of Starship/Superheavy are absolutely set in stone.

>>12093675
There would need to be some market research to see if you could actually pull that price.

They consider the vulnerability of their spaceports to foreign attack so even though Hainan is the best place for one they delayed it for a long time. But my guess is since they built up their military capabilities quite a lot while the US is slowly losing its grips on south china sea they can do it without too much worries.

>>12093716
>while the US is slowly losing its grips on south china sea
lol

>>12093707
Space launches are significantly cheaper now. Plus 50k is the starting bid.

>>12093490

>>12093707
Well, that's hyperbolic of me, math says a kilo should just about cover two Falcon Heavies. You could get a vehicle just about half Apollo's size to GTO with a FH. Let's just assume it picks up a rock half the size of Big Muley (largest ever single sample of Moon rock) weighing in at around 5.85kg. If each kilo pays for two Falcon Heavies, you'll get the value of ten Falcon Heavies for every one launch and successful return. If you divide the total rock collected and spread it evenly among Apollo landings, the average rock collected was 17.27 kilos. Assuming a FH automated Lunar mission collects half as much you'll be paying for 17 new expendable Falcon Heavy launchers per each successful return mission.

I'd say a 17-fold profit margin would be a pretty sweet deal.

If the Shuttle had been as cheap as advertised, that would be a very reasonable way to get satellites or probes to higher orbits. Starship would let you do the same thing with a kick stage the mass of the entire Shuttle (80 tons) for a 70 ton payload, which is way cooler.

>Aerospikes
Bad technology everywhere in the solar system except for Titan and Venus, in fact anything other than vacuum optimized is bad for any vehicles operating in greater-than-Mars-atmospheric density.

The actual future breakthrough in propulsion will be microfission rockets; think Orion drive but instead of kiloton yield nukes you're using a superconducting magnet to crush a fuel pellet the size of a pea enough to cause it to go supercritical and release the energy equivalent of a few hundred kilos of chemical propellants. Even at a pessimistic Isp of 50,000 and a dry mass fraction of 80% you'd have a vehicle capable of doing 100,000 m/s of delta V easily. A slightly more optimistic Isp of 80,000 and a mass fraction of 50% gets you over 500,000 m/s of delta V, easily unlocking everything this side of the Kuiper belt for human exploration and eventually colonization.
To put it another way, a microfission tug vehicle that had a mass fraction of 50%, Isp of 50,000 and a total wet mass of 30 tons would be able to throw 970 tons onto a Mars intercept starting from LEO. Alternatively, it could push 570 tons of payload from a circular low Earth orbit all the way to a circular Mars orbit, in one stage. If 400 kilograms of that 570,000 kilograms of payload were reserved for fuel pellets, the 15 ton tug would have enough delta V to get all the way BACK to a circular low Earth orbit again.

>>12093808
At 1N/W the question of how they actually work starts to matter a great deal - if they're baby Alcubierre drives you could reasonably crank the thrust up to 1g for a year and go FTL via steady acceleration. If they aren't expanding space they're still crazy powerful sublight torch drives.

Unless I read that post wrong and you're asking when they reached 1N/kW, then that's currently being claimed by a couple of groups, with one in Nebraska claiming 15N/kW and another in Spain claiming 0.7N/kW.

>>12094000
those are lame though

I am a brainlet with a question about re-entry: why does it have to be done at such a fast rate, meaning all that heat and shielding. Why cant they use reverse thrust to slow pretty much to a crawl, and drop in at no greater than terminal velocity? Is it a case of not having enough fuel to do that?

>>12094225
you're lame

>>12094226
the whole point of getting hot is so that you don't need to do that because it's even more of a pain in the ass than getting hot

>>12094226
that's what you do landing on airless bodies,but the problem is that you need a rocket just as big to land as you needed to launch in the first place vs using the atmosphere where you just need to make contact with it and it does all the rest of the slowing down for free

>>12094226
It's called aerobraking. If you don't aerobrake you need to decelerate all the way from orbital velocity to landing speed with rocket thrust, which means you basically don't have any room left over for payload. It's way easier to aerobrake.

>>12092716

other than mars or venus what are the other colonizable planets that our fragile meatsack bodies can endure.
BTW do you guys realize what will considerably slow down our colonization of the galaxy is our earth bound physiology. I just cant see us being at 1trillion strong and still being meat based creatures.

Assuming the world doesnt end
i can already see the future headlines in a 1000 years unless the physiology issue is resolved
"50 million die from fluke atmospheric decompression caused by a faulty valve on the osiris prime oneil cylinder, near the saturn sector. Authorities said millions died instantly only people who survived are crew who were doing repairs." sol system news network

Counterargument - short, fragile life is the only thing that motivates us to work towards FTL or at least relativistic starships. If you can hibernate for a thousand years in hard vacuum, a slow boat at 1% the speed of light would be perfectly adequate for getting to Alpha Centauri in a single generation.

maybe but space is dangerous very dangerous and making it far less dangerous means dealing with the physiology issues of space like lack of oxygen and radiation.

Opps the reactor had a small leak looks like you now have insta stage 4 cancer.
Also there are literally some planets we cannot go near to because the radiation will kill us.

unfortunately the only solution i can see is to hybridize with cybernetics or bio engineering and shed as much of our biological functions as possible.

Why is it that I haven't heard anyone advocate for getting started on orbital port infrastructure? Surely assembling or buildings ships in orbit such that they don't need to get off the atmosphere would make everything easier?

Although maybe refueling is a start.

>>12094534
There are several organizations working towards that, the most notable of which being The Gateway Foundation.
https://youtu.be/hJ6wwA9wXog
The bigger question is whether or not they can actually do anything, if this is an intentional scam to get cash, or if they are just deluded. My gut tells me that this is too early; wait a decade and then you can make all of this happen much more easily.

Do you think the shuttle will ever get like a reunion tour? Like one day when space is easier they'll just dust one off and launch it just for old time's sake, maybe get it to dock with whatever super space station we have then.
Shuttles are cool man, even if they weren't so useful.

>>12094633
Any long term colony that is reliant on resources from earth will forever live under the shadow of politicians trying to shutdown the program to make the other guy look bad. Modern politicians will gladly let martian colonists die if they can use it as a political point.

People don't stop flying when an airliner crashes

>>12094643
I don't see your eventual point. How letting martian colonists die could be an advantage for politicians.

>>12094649
Airlines are big money, there's an incentive to keep them running. Space travel COSTS money, there's an incentive to shut them down. The two are not even remotely applicable. Also if 10% of the peole who'd ever been to space in the history of mankind died in a single incident it's a bit of a bigger deal than a single flight of a single airliner out of tens of thousands crashing.

Anon, Crew starship won't be a government operation, congress won't have control over it. Plus, the plan isn't to start sending 100 people into space at once. There would be thousands of people, potentially tens of thousands, who had gone to space before they start sending 100 people up at once. Plus, space travel will eventually start making large amounts of money.

>>12094806

>>12093826
>please share either your evidence
The fuel pellets are being detonated as tiny fission explosives, Orion drive style propulsion can get you 50,000 Isp when your fuel is being weighed down by bomb casings and tamper elements etc and your "nozzle" is a flat plate, so having relatively pure fissile pellets and a large magnetic confinement nozzle should at LEAST match the better estimates for Orion pulse propulsion.

i wanna see another hop

>>12094026
Yeah dude, They're bad in that the atmosphere on Earth is simply too short and too low density for the advantages of aerospike engines to outweigh the disadvantages.

>>12094806
Note the "~" signifying "around".
Also you're full of shit, the first crossing of the Atlantic by a steamship was made in 1819 (https://en.wikipedia.org/wiki/SS_Savannah)), mainly under sail power, plus it was converted back into a sailing ship because the technology wasn't mature enough. Cargo sailing ships still operated between the world wars (https://en.wikipedia.org/wiki/Flying_P-Liner).).

>>12094595
>How are you powering that magnet?
Superconducting magnets act like permanent magnets unless they warm up past their supercritical conduction temperature. Just like an MRI machine, the magnet is just there once you have it cold enough and have pumped it full of electricity to get the electrons swirling around.
Keeping the magnets cold WILL require power, and a big radiator, but if you're clever you can use helium as your magnet coolant and your heat engine working fluid, and in a way have a cooling system that is powered by the waste heat that builds up in the magnet (and other solid bits surrounding the fission chamber).
I never said a microfission rocket would be easy, otherwise we'd already have them. I said that they are what will be the next big breakthrough in space propulsion tech. We could probably put together a proof of concept microfission pulse experiment using nothing but modern tech. The biggest barrier to producing this type of propulsion system is probably trying to just get approval and funding to build the facility that can test this kinda thing; its exhaust would be a mixture of unreacted uranium or plutonium and a significant amount of fission products.

>>12094825
Steam blew, actually. Steam only sucks if you keep the valves closed and let the boiler cool down.

Ultra-broad gauge rocket carrier trains when?


I can see NASA building a small 10 or 15 foot gauge network at Cape Canaveral specifically for moving rocket parts or even complete launch vehicle assemblies from storage to the launchpads, replacing the shuttle crawler that tops out at 1mph and takes 5 hours to reach the pad. They can use Caterpillar marine powerplants as engines for a top speed of a more appropriate 30mph.

I wonder what the locomotives would look like.

>>12094959
Most likely issue would be blood flow, however by living in elevated gravity their entire lives their bodies should adapt physiologically as they develop (slightly bigger, stronger hearts, stronger diaphragm, not to mention musculature). Also, small kids don't weigh much to begin with, so it's not like 2g is gonna wear them down as much as it would a tall man used to Earth gravity.
Remember, once the kids stop growing they can leave the gainstations to go live on other, lower G orbital habitats, or on Mars, or if they want to they could even go back to Earth.

Was BO just a money grab from NASA?
Literally no customer to send to 'space'
Can't deliver Engine to ULA for testing.

>Virgin Orbit: Flexibility and speed of design, build and deployment made small satellites attractive. So, we built a launch system aligned with those strengths. Using a Boeing 747 as our ‘flying launch pad’ is the key to that. We can fly from regular runways all over the world and take our launch site wherever it needs to go—which not only means we can directly inject into every type of orbit, it also means that we can tailor every launch to the specific needs of the customer and the moment, whether that’s political interests, weather or whatever else. Our other big differentiator is that we are a Virgin company; having not only the financial backing but also the global network of suppliers, experts, customers and everything else is enormously helpful.

They work in an atmosphere but:
>Ion thrusters in operational use have an input power need of 1–7 kW (1.3–9.4 hp), exhaust velocity 20–50 km/s (45,000–112,000 mph), thrust 25–250 millinewtons (0.090–0.899 ozf) and efficiency 65–80%[3][4] though experimental versions have achieved 100 kilowatts (130 hp), 5 newtons (1.1 lbf).[5]

>one superheavy hop
They’re gonna have the first superheavy test article done before the 20km hop? Are they already building one out?

Tantares gud

>>12095478
>Doesn’t smarter every day have a video where he visits nasa and touches the torch of a small little ion thruster
I think it was at his PhD advisor's lab at UA Huntsville, but yeah.

The recent military war game was hi tech. Not sure if they used Starlink this time but they've used the satellites for testing the same system in the past.

>>12095537
What's this one supposed to test?

>>12095569
Got video or something?

>military grade spot
what was it used for? scouting building interiors I assume? Doesn't look very armored though

>>12095572
No there's just a few pics and press releases. It says the war game was led by US Space Command, and space overly secretive.

afaik, new steel alloy pressure test

Why do people type "klick" instead of typing "km"? I know that speaking "klick" is easier than speaking "kilometer" - but isn't typing it just harder?

What is the lawson criterion for proton-proton chain fusion?

>>12095600
surprised it's not boston dynamics. Did they steal the designs or something? Looks identical. Also I saw some vids of it walking around and looks a little slow, also really sucks at going up stairs

>>12095605
I never heard of them either. I thought it was Spot until I read the article. When I was looking around it says there are at least 4 companies with robot dogs, including one Chinese.

Using leftover steel foils to make a fence, yep that's SpaceX all right

>>12095685
It’s funny to think stainless steel and methane is the future. And to think my oven is steel and burns natural gas... it’s basically the same thing hahah. I want a stainless steel fence around my castle when i’m retired
