>Entrepreneur Launches Low-Cost Space Rockets

Thoughts? looks promising

>The cost savings come from reducing the launch team from hundreds of people to 15–20, making the first stage reusable, building most of the rocket in-house, and deploying the latest technologies. Unlike current rockets, Falcon V is designed to be able to lose an engine and still deliver a payload to the correct orbit. SpaceX, based in El Segundo, California, already has signed customers such as the government of Malaysia and the US Department of Defense, and interest from the science community is growing. Researchers from the University of Washington, MIT, and the University of Queensland hope to launch the Mars Gravity Biosatellite on a Falcon in 2007. Musk has received dozens of inquiries from potential customers. “I would be happy if Falcon I achieved a four-to-six launch rate per year. It looks like we will probably do even more launches of Falcon V, once that gets going.”

>>15232234
>Starship may not reach expectations. It may operate, but at a much higher cost and at a reduced mass capability, or on-orbit refueling may not be achieved. The Starship launch costs given by SpaceX are presumably estimates of the cost to SpaceX, not the price to a customer, which will be more expensive. Perhaps most importantly, realizing dramatically lower launch costs depends on rapid and frequent reuse of each Starship, but a market for sufficient launches may not be forthcoming. The anticipated savings promised by Starship also may prove illusory after careful inspection.

Reminder that TakeTwo Interactrive fired the original staff of KSP and hired a new one to take control over KSP2.

Don't give them shit.

>>15232292
>take over company

Don't often see that.

>>15232234
>Even if Starship works as advertised, extra mass is not without disadvantages. More mass increases the moment of inertia of the spacecraft and so requires more massive reaction wheels to point to a target. In addition, station keeping in the popular Sun–Earth L2 halo orbits either will require proportionately more propellant or will limit mission lifetimes because of the extra mass.
THEN DON'T DO MEME ORBITS LIKE L2?? HELLO????

>>15232290
They're right, important to keep that in mind and not fall for mindless hype and all eggs in one basket thinking

>>15232312
even if refuel or reuse fails I think they can still pull it off but will be much more limited

>>15232302
Why is the Sun–Earth L2 location a meme?

It's funny how they immediately ruined engine balance by putting in a hypothetical gas core engine.
To be fair it was already a bit messed up by the vector in KSP 1, but now there is practically no reason to not use that engine for everything outside of atmosphere.
I wonder how well implemented the hydrogen tank mass ratios are as well, probably not very.

>>15232323
It's not. Stationkeeping is also not a concern just use electric propulsion.

>>15232323
because astronomers are prissy

Midwit take. Having torchship engines in your space game is absolutely a good idea.
What you want is a career mode where those are very hard to get and a sandbox mode with lots of realistic options the simfags can use instead.

>>15232333
>gas core NTRs are torchships
they are not

>>15232329
cant be done, too expensive. be careful shilling for this because soientists are already crying about not allowing NASA to fund a starlink infrastructure around the moon because we need to maintain radio silence on the moon

>>15232336
Not the point. Anon was complaining about balance.

is this actually happening?

>>15232210
Should use something like that on McMurdo station.

>>15232370
Musk is delusional

>>15232325
>caring about engine balance in a game with interstellar travel

>a game with interstellar travel
OH NONONONONO

>>15232333
The point is that in the current state of the game there is basically no need for this kind of engine.
In KSP1 for a long time they tried to ensure a reasonable balance with the available engines so that everything had a use, even in sandbox mode.

This is the kind of engine you would use for actually interplanetary colony work, at the moment with the game being effectively Duna and Eve it just feels like a cheat mode that cheapens the experience.

>>15232333
From what I've seen in videos it looks like the hydrogen tanks are taken directly from one of Nertea's KSP1 mods, so they're probably pretty good. What baffles me is their insistence that all the previously-understood-to-be-kerolox engines are no methalox, despite having none of the characteristics of methalox engines.

Stop arguing and post cool space photos

>>15232423
Like either you do multifuel or you don't.
There was a reason it was how it was in the old KSP and why the game deliberately limited it's scope.
Now you have the problem of not only kerolox and hydrolox, but also all of the hypergolic fuels, then you start getting into the pros and cons of each system with re-startability, boiloff, density ect. It all becomes a lot more complicated.

Making a game with advanced propulsion systems, that feels authentic still to autists but is still accessible to normies is very challenging.
Like as it stands at the moment, it feels poorly conceived and it bothers me, the same way that the ASOIAF TV adaptation bothered me as soon as they started diverging from source material.
It feels like whoever is making decisions doesn't really 'get it' if you know what I mean, it's not that I am against changes, it's just that the changes don't make sense in how they are implemented.

>>15232423
I checked, hydrogen tanks have the same 1:9 mass ratio as the methalox tanks

they're much less dense however. like 3-4 times less dense.

>>15232493
To build on this, the original KSP has plenty of unrealistic features in the game, that were a part of designing the balance around a subscale earth and solar system.
Engines have low TWR compared to real life and tank mass ratios are poor. If they were realistic, then it would be trivial to build SSTOs for everything, indeed some degree of powercreep was already making this the case in KSP 1.

If you are going to use realistic fuels do you now have to use realistic tank and engine weights? Or does that have to continue to be pseudo-balanced? It's all a lot more complicated than just copy-pasting assets across from the old game.

Why is nobody addressing the elephant in the room? Due to structural issues, SpaceX currently is not able to make a regular cargo Starship. First we had those prototype payload sections that were tested once, but didn't appear in prototype. Then they switched the Starlink dispenser and it also caused problems. Its how mass caused the steel to bend around the door and thet led to "armor" being installed on S27.
How can SpaceX overcome this issue?

>>15232195
Photovoltaics were really bad at scale until the mid 90s. Solar thermal was space and weight competitive at the time. There's a 1989 NASA study on PV vs. thermal for Freedom that confirms it. This is also why NASA used chemical fuel cells on Apollo and the Space Shuttle. By the time the ISS was actually built, photovoltaics had improved to the point that was no longer true.

>>15232674
>How can SpaceX overcome this issue?
More structure, more mass

it's relatively unimportant compared to the test flight coming up. that's why they didn't fix 24 instead opting to go without a door.

they might have laserlinks, but maybe that equipment takes too much space/mass to put on these miniversions (750kg)

I'm terrible at algebra.
But the physics community is stunted by the incorrect theory of relativity, which is why there have been no advances in 50 years.

>>15232710
After seeing so much rocket material for years I have come to the conclusion that the only reason why we aren't a space faring civilization it's because our whole civilization is suffering from something similar to a median income trap in which it is simply much easier and cheaper to extract our resources and study things from afar than actually start colonizing Europa, Venus or Mars
>B-But The technology is not there
The technology has been there since the 60s, and engineering issues had been solved by the 90s, to the point where some weird south african with autistic ideas and some money could simply contract his own engineers and do things that were though decades before

At this rate, the only way we might start becoming colonizing the solar system will come first from brain uploading and ubiquitous nanotech(therefore sending laser propelled milligram seeds) than through the actual effort of building the rockets and habitats, therefore reducing the barrier cost.

So how does this change the rocket equation?

>>15232731
Saying that "It's all been solved!" is just announcing to the world that you don't really understand why it hasn't been done yet. This is further confirmed by saying that the only way it'll ever be done now is through voodoo science magic. "Brain uploading nanotech" is just the reddit atheist's way of begging a wizard to conjure away the things they can't comprehend.

>>15232756
Or a way to cynically say that we will never see spaceships because the whole world will advance in literal magic than actually trying to do what is already possible, meaning that no one cares about technological or scientific transcendence but pure material hedonism(which oddly enough it is a point in which I can agree with most religions although not in the ends).

And yes, it has all been solved, what it has not is been built and tried but NTR have been a thing since the 90s as proven by the 15 prototypes built by the soviets.

These two things are mutually exclusive statements. Ideas have been proposed, but there's worlds of difference between a paper on the NASA Technical Reports Server and a mature technology.

How so? Take away money from some government department and no one bats an eye, take away money from NASA and outside some minor inconveniences and no one cares.

The literal obliteration of NASA budget in the 70s is proof of this, some people actually cheered it as a way to reduce inefficient government spending instead of seeing it as the death of the space dream.

>>15232801
Why didn't we stick with the shuttle? There were still two left that hadn't killed anyone

>>15232809
Because it was an expensive piece of shit.

>>15232794
The Apollo-era budgets were not sustainable and were never intended to be. The "death of the space dream" didn't come from budget cuts, it came from building communications satellites with transistors instead of fragile short-lived vacuum tubes and from the energy crisis of the 1970s being solved through terrestrial rather than extra-terrestrial means.

Again: please go outside.

That's why they projected a refueling base for the Moon and a possible Mars mission in case the Moon race failed? It almost feel like they actually intended to keep the missions going on, as it happened, but sure thing they weren't sustainable because no one cared when they died and everybody just expected NASA to build a space plane that the magical private industry could pick up and mass produce.

Comm satellites did not help, that is for sure, which comes back to my original point; we would rather go through the easy means here than actually try to imagine a way to do it outside.

The energy crisis was artificial as hell, it wouldn't have lasted much and it's a circus trick that can't work twice unless we finally get the famous peak oil and countries find themselves actually unprepared, it did not help but it wasn't determinant.

>>15232830

Chemical rockets aren't the only rockets. Nuclear is real and it's lack of use has nothing to do with a failure of physics.
Also chemical rockets can and do reach the moon. Cope on Reddit

>>15232867
Ok, what propulsion system do you propose which does not rely on mass ejection?

>>15232861
Just an uninspired troll. Eric Weinstein went on Joe Rogan recently and complained about:
The stagnation of physics and that his obviously great ideas that have been sidelined.
Elon Musk having a wimpy chemical rocket company with the goal of saving humanity.
He was exasperated that he has not met Elon Musk yet despite them sharing a lot of friends.
Implied that his physics could offer breakthrough propulsion technologies.

Be could be an interesting person is he wasn’t so autistic. His brother talks about biology, btfo sjws and lots of people like it.
If Eric would just talk economics maybe people would give him more attention. Just ask people on Twitter what they don’t understand, it’s not that hard.

Has anyone studied the efficacy of antipsychotics in space? Asking for a friend on reddit.

What is a magnetic field?

>>15232931
The plasma magnet (Slough and Giersch, 2005; Slough, 2007) would use a polyphase antenna onboard the spacecraft to drive currents in the surrounding medium, creating a magnetic structure that would inflate via self-repulsion until the magnetic pressure is balanced by the dynamic pressure of the impinging solar wind. The plasma magnet appears particularly encouraging in that it is able to interact with an enormous volume of the solar wind (e.g., tens to hundreds of km in extent) while only requiring a small antenna (e.g., meters) with modest power requirements.

Getting to the surface of mars from the surface of the moon takes less fuel than getting from the earth to low earth orbit. Now getting from the surface of Mars back to earth, that takes substantially more.

My guess is that we would make some kind of refueling station in high orbit around the moon, then construct an unmanned refueling station in orbit around mars. Most of your fuel budget is spent just getting off the surface and into orbit. Once you are into orbit, the amount of fuel to go from orbit A to orbit B is comparatively less.

>>15233062
>Now getting from the surface of Mars back to earth, that takes substantially more
Can't be cause a single stage can do it.

>>15233066

When they ran into problems with fuel tank, some NASA director decided it's technology demonstrator, and won't become anything else than technology demonstrator. So he insisted they will fix the composite tank, or there is no point in this project at all. Then told Lockheed that they will have to fund the project out of their own pocket. Then new chairman of Lockheed said fuck this shit, and pulled out.

Minimum 2, maximum of 10. Next year, minimum of 10 and maximum of 25. The year following minimum of 25 and maximum of 50. Expect it to exponentially increase with each year thereafter.

Is Xenon ideal but too expensive or something?

>>15233427
It pure performance it is since it's relatively dense, high atomic mass and easily ionized which means you can store more in the same space of volume while getting a higher thrust for the power put in. Expensive as shit though.

>>15233427
expensive and only getting more so as demand grows but supply doesn't, there just isn't enough demand for it to justify increasing production

It hates you too, always.

How many BE-4s can BO make/made so far? I doubt there is enough to go around between them and ULA

This is an old photo and it’s not even real hardware

Watch ULA get frustrated and switch to Raptor

Equatorial launch was a bigger consideration back in the 80s and 90s when everyone was trying to loft big payloads up to geostationary orbit and they needed to squeeze out every bit of performance that they could. These days everyone's launching smaller payloads to SSO. Sun-synchronous orbits are latitude agnostic and none of the small launchers they could fit onto the floatport are going to be big enough to lift GEO payloads, so latitude doesn't factor in that much. You'll get some extra performance from going further south, but that seems secondary next to the simplified paperwork and lack of congestion.

That said, I'm not sure I buy the argument that US spaceports are overcrowded. Rocket Lab has Wallops all to itself 98% of the year and while SpaceX is keeping the staff at the Cape and Vandenberg busy I don't think they're too busy to be able to fit a RS1 or Alpha launch into their calendars given their low overall flight rates. That's not even getting started on how neglected Kodiak is currently.
