What are the odds that Relativity successfully makes it to orbit on the first go?

>>14547214
1/3

>>14547214
50-50. They have loads of talent and seem to be taking their time to get it right (in other words, BO with more drive), but I thought the same of Firefly. While not openly cocky about their odds like Firefly, Relativity's manifest seems to count on early success (ELANA on flight 2 like Virgin Orbit had, block upgrade with flight 4).

I'd just like to interject for a moment. What you're referring to as Orion, is in fact, SLS/Orion, or as I've recently taken to calling it, SLS plus Orion. Orion is not a launch vehicle unto itself, but rather another multibillion dollar component of a partially functioning pork system made useless by the SLS subcontractors, shitty designs, and Alabama river rocks comprising a gigantic scam as defined by the GAO.

Many taxpayers fund a small part of the SLS scam every day, without realizing it. Through a peculiar turn of events, the version of SLS which is widely mocked today is often called "Orion", and many of its victims are not aware that it is basically the SLS scam, developed by the SLS lobbyists.

There really is an Orion, and these people are seeing it blow up, but it is just a part of the scam they fund. Orion is the capsule: the payload in the system that allocates the government's resources to other districts that need pork. The capsule is an essential part of a launch system, but useless by itself; it can only incinerate astronauts in the context of a complete launch system. Orion is normally used in combination with the SLS boondoggle: the whole scam is basically SLS with Orion added, or SLS/Orion. All the so-called "Orion" debris fields are really distributions of SLS/Orion.

hey guys, so when is the faa gonna giv elon musk a permit?

I think the FAA delay was good for spaceX, they really probably need 1-2 months before an orbital flight, for engine testing campaign, stacking, tile congruence

>>14547377

Biden has always been a major secret fan of Elon Munsk. He's personally asked if any corners can be cut to clear any red tape

>>14547399
Biden said launch it NOW but Elon keeps asking for delays.

>>14547405
Elon could just pay for it if he wanted to. He has 100s billions of dollups, if he really wanted he can buy it. He hasn't done that and I believe in my humble opinion it truly shows where his priority is at. Chew on that one

New Rocket Lab / CAPSTONE article
>WARNING NOT WORTH READING
https://www.stuff.co.nz/business/128730606/rocket-lab-about-to-shoot-for-the-moon
some Beck quotes:
>This is a mission all New Zealanders can and should be proud of. We're going to the Moon and so few countries can say that (kiwianon: SUCK IT LOOSERS)
>The Moon has remained virtually unexplored for the past 4½ billion years
>When you think of Moon missions you think of the enormous Saturn V rockets of the 1960s and billions of dollars, but we’re going to the same destination with a carbon fibre rocket and our Photon spacecraft the size of a bar fridge, all for just a fraction of that cost
>Going to the Moon is no joke. It is incredibly hard, and it has taken an enormous amount of effort and dedication from the team to get us to this point

>>14547521
Good job boyo

>>14547521
(nobody tell him he's only going to NRHO)

re: the discussion in the last thread, i'm pretty sure that glushko could've had something like a hypergolic rd-170 ready to go by the late 60s if he and korolev could've reconciled. ORSC is much easier with N2O4 than LOX and energomash had a lot of experience with it from working on proton, and splitting the combustion chamber would've given it a much speedier development than the RD-270 was getting when it got nixed (and even that had several successful test fires, somehow).
It wouldn't have had the performance of the RD-170 but it probably still could get a sea level ISP in the 285-290s range like the RD-253 had. If you have 6-7 of those on the first stage and keep the NK-15Vs on the second and third stages then that might be a viable moon rocket.

>>14547521
Boring, Mars is cooler than the moon and infinitely more useful. Fix your country, you faggot kiwis.

Terran R will fly before Neutron.

>>14547510
I'd argue they already have. 3D printed engines (Delphin, Rutherford) own the small launch space, and Rocket Lab's composite tank laying system is almost totally additive manufacturing. Relativity attempting to proont the whole rocket on one machine is certainly new, but SpaceX and Astra have both settled on rolled metal welded together for tank bodies for cost reasons.

>>14547593
That grift really blew my fucking mind. Like at least you can handwave expendable rockets (for now) if the mission can't be done on F9 but reusable paved roads are literally ancient Roman technology. Expendable roads SPECIFICALLY FROM ALABAMA.

>>14547581
He is forced into repeatedly humiliating himself as a result of his former association with Ghislaine Maxwell and Jeffery Epstein. Doesn't really own Amazon, but he is allowed the trappings of wealth in order to make it seem like he is really in charge. The hundreds of millions of dollars him and zuck were forced to part with during the 2020 presidential election shows you who is really pushing their buttons. The tranny in ur picrel is just another public humiliation he is forced to endure in order to prevent data leaking out of the Epstein/Maxwell files. Most of the money the government pays out to Amazon ends up back in the pockets of Bezos' handlers. That explains why Blue Origin provides so little bang for the buck compared to SpaceX, its not that SpaceX is that much more skilled, its just that SpaceX's budget doesn't have a 90% graft skim factor. 10% for the big guy was his fee as vice president, no doubt its now a larger percentage.

A quick reminder that, for some time now,
@NASAPersevere
has had a rock stuck in its front left wheel.

The rock doesn't seem to pose any problems.

But take a moment to think about the awful grinding noise that thing makes as it slides around every time the rover moves.

Just think. That rogg has sat motionless on Mars for millions of years, and now its being taken along a journey that it wouldn't have imagined. In a hundred years when humans visit the irradiated remains of the rover they can look at the little rogg that could.

>>14547621
von Braun himself was slaying pussy all the time before he settled with his wife, it's practically tradition.

>>14547924

It's just a play on dolphin sex being taken literally instead referring to pic related, although I don't think it's a common term outside of /sfg/.

A SSTO that could reach Mars without refueling would be nearly impossible to build even with hypersonic airbreathing engines and the payload would be next to nothing. Spaceplanes are not a worthwhile endeavor on either planet but they would be especially bad in the thin atmosphere of Mars and it would likely need propulsive landing.

>>14549065
An optimized spacecraft is mostly fuel. Propulsive landing fixes the need for heavy wings or parachutes in favor of just a little extra fuel in a tank that you already have anyway

China launched 55x in 2021. It's reasonably to assume they'll double that by 2031, and if they've figured out reusable rockets by 2035 in the same class as Starship/SuperHeavy, then you can reasonably double that again. So ~2-225 launches a year. More importantly though, in context, I don't think China considers SpaceX & America as one item and instead compares itself more to NASA and legacy providers the world over, and in context of that, that statement could be true.

SpaceX is in a class of its own and trying to compare yourself to them, when you're about a decade behind the curve is silly.

What's the lowest orbit you can get away with for Starship refueling? 80km, 70km? How much payload does that gain you? (mind that every payload gain is also additional fuel carried on each tanker)

Are there ever going to be reliable enough launch vehicles that such measures may be considered unnecessary? Falcon 9 and Soyuz may be close there, but is a different approach entirely (perhaps more like Starship?) necessary? Assuming no anti-nuclear, russian funded """environmentalists""" can stop it, if safe enough.

>>14549513
>electric thruster use melted indium as propellant at about 5000 isp
Why indium, why does it always need to be these exotic propellants, just use lead or molten aluminum or whatever (they want to use 700 degree indium which is 40 degrees hotter than molten aluminum and in space there's not oxygen so all liquid metals are pretty equally non-reactive/non-gunky)

>>14549513
>uses cobalt-60 to generate electricity
Why make Co-60 when you can make Sr-90, which is a beta emitter and therefore turns a much greater percentage of decay energy into thermal energy in the fuel while requiring little to no shielding?

>>14549512
Well that was disappointing. I'll be back next year.

>>14549562
With or without 150,000 kg payload? Because all the calculations I've seen show fully loaded Starship with max payload achieving ~6900 m/s of delta V and minimal cargo Starship achieving more like 8800 m/s. Combine that with refilling in a highly eccentric Earth orbit and you can throw pretty hard, of course that's not as flexible in terms of where you are expending your delta V compared to electric thrusters.
That's kinda moot anyway because the proposal actually talks about delta V above 100 km/s, not ten.

>>14549654
indium has the right ionisation properties and costs $400 a kilo, its no big deal

calm down Ned Ludd

>>14549627
This is a bizzare argument because Ultra Safe's craft isn't trying to move large amounts of payload and Starship isn't trying to conduct maneuver warfare with dozens of orbit changes without refueling (or running down an extrasolar object).

>>14549721
It's an argument for 10km/s dV being laughably little for muh nooclear. If its actually 100km/s then its better.

>>14549727
Even 10 km/s is outstide of what is possible with chemical engines unless you put a tiny payload on a super heavy lift rocket.

>>14549736
>being this retarded
It's possible with 20 metric tons of payload on a stretched Starship without flaps.
It's easily possible on a hydrigen vehicle.

>>14549660
Sr-90 is a fission product, so you need ot rip apart fuel to get it. You can't make it by irradiating natural strontium with neutrons because natural strontium only goes up to isotope 88, and strontium 89 has a half life of like 50 days, which means you need to achieve a double neutron capture which is very highly unlikely to happen to a significant portion of the Sr-89 you make over the course of its half life.
The first advantage of a chargeable atomic battery over that of a normal RTG is that your isotope power source is produced by bombarding a target with neutrons, not by fission, so in theory you can have a hundred of these power source targets just sitting around with zero radioactivity, ready to be loaded into a reactor core to be cooked under neutron flux for a year prior to final payload integration and launch. The second big advantage is that you can generate a lot of fuel isotope very easily compared to trying to breed conventional RTG fuels inside of reactors. You want a fuckin' 100 kW thermal heat source? Bake your target for longer and load her up.
I will say that I think Co-60 is a shitty RTG heat source. It has a high specific activity due to its half life of just 5.271 years, but it emits a lot of energy as gamma rays which mostly leak away and don't heat up the fuel. Also, nice job picking a power source that will go from X output to just 6.25% of X after two decades jackasses.
In my opinion I believe Ni-63 would make for a superior power supply. You make it from Nickel-62, which is not common in proportion to nickel isotopes but is common in proportion to most elements in Earth's crust. Also, the other natural isotopes of nickel are all either stable or have a half life of over 76000 years, so there's no barrier to breeding Ni-63 from just regular chunks of nickel except time. Nickel-63 has a half life of 101 years, and it's a *pure* beta emitter, so the amount of decay energy that will be retained in the fuel as heat is over 99%.

>>14549720
Miniaturization of electronics is good. Miniaturization of entire vehicles is irrelevant to human spaceflight and is therefore not worth it.

cont
So Ni-63 gets you a very long lived power source (Pu-238 has a half life of 87.7 years) which you can fabricate cheaply and easily as nonradioactive target blocks, and which you can irradiate to "charge" very easily as well. The battery is much more efficient than a Co-60 decay powered device at these scales due to lack of gamma ray leakage, and hand in hand with that benefit is the almost nonexistent shielding requirements due to being a pure beta emitter (only radioactive leakage of note will be a small xray flux). Such a power supply wouldn't just be highly useful for throwaway high burnout velocity electric probes, it would be a great power and heat source for human and industrial space activities overall. Want to melt unlimited water but don't want to deal with any gamma or neutron fields? Big ass 100 kWt, 101 year half life nuclear battery will do that for you, and it will still be making 25 kWt continuously over two CENTURIES later.
There's also the possibility of using kilopower-sized reactors along with big nickel wraparound jackets that catch the neutron flux to create a kind of rechargeable atomic battery, where you have a reactor core that will run for 20 years surrounded by a jacket that undergoes a decay half life of 101 years, and requires 2.5 years of reactor operation to "charge" with Ni-63. You now have a power source that supplies between 100 kWt and 50kWt for the next 808 years, and then tapers off on the normal decay slope afterwards, so you still have over 25 kWt of supply even after 1000 years. That's legit interstellar probe power supply levels of performance, maybe not huge power budgets but definitely good enough to keep the thing operating until it arrives and can switch on a dedicated primary mission power source.

Harsh winters don't really exist when you live on a settlement where 100% of your farming occurs in a controlled environment setting and you're set up in the tropical zones of the planet (good sun angle above the horizon year round). You would need some kind of slime mold mystery plague to rip through all your farming volumes at once, and quickly enough and severely enough that nothing significant can be saved, and also you need to not have a larder stockpiled with 5+ years worth of freezerpacked food from Earth, and also I guess Earth needs to not be capable of sending further supplies either. To safeguard against these, you build up Earth space launch industry and overall space based industry to the point that shutting it all down would be unthinkable (like trying to shut down ocean transport), you always keep a large nonperishable food supply in stock, you constantly monitor all plants and soils and water loops and so forth for unexpected living things like bacteria, pests, fungi etc, and you build many many farming volumes that are as disconnected from one another as you can afford, ideally separated in terms of ventilation gradient as well as physical distance and water supply (this is where you have your HVAC system pulling air out of the farming tubes and up into the filtration system before being blown back around and into the farming tubes, so that air never flows downstream out of one farm and then upstream into an adjacent farm. Also you probably want to manipulate temperatures, air flow, humidity, and UV exposure so that while the plants are growing as happily as they can, it's a nightmare hellscape for mold and bacteria.

It's at least within the realm of engineering possibility much more than literally any SSTO concept has been. You would likely need to remove TPS, remove flaps, remove header tanks and associated plumbing, remove batteries, etc in order to actually hit 10,000 m/s with Starship but that's what makes it plausible. Meanwhile you have actual designed and funded and partially developed concepts like Venture Star which were going to need to hit 10,000 m/s using hydrolox on a vehicle which needed the TWR to lift off from the ground and all the TPS and landing gear and such to reenter and return to be reused after flight.

It is completely inevitable that once humanity settles in space, the chains of Earth will be cast off. It doesn't matter if the chinese get there first and establish a 10,000 year stranglehold over the entire solar system, it WILL eventually break down and the resulting rush of expansion will preclude any single tyrannical entity from dominating over all of humanity ever again (I read it in dune once)

>>14549889
You still haven't pointed out why they would pick a gamma ray shidding short af half life radioisotope. The only reason I can think of is that it would offer a lower mass ratio for its power output at the start of the mission, resulting in higher accelerations. However, fuck higher accelerations you are using electric propulsion anyway. Using a nickel radioisotope power supply results in 20x the mass but power that lasts 20x longer, so you can reach much higher velocities before your generator can't feed your thrusters anymore.

>>14549915
>the chains of Earth will be cast off
The chains that binds humanity to Earth needs to be cut off forcibly. It will be painful, but it needs to happen. How painful depends on how hard the chain is. We'll probably need to sacrifice few billions of the Earthers so that humanity can be free.

>>14549971
You solve this by holding the LH2 you make in a tank on the ground hooked up to a cryocooler so that as the spin isomers decay into their stable state you are continuously removing that generated heat, then after a few weeks or whatever your LH2 is long-term storable. Spin isomer decay is energetic enough per mol that it would cause a large amount of boiloff, but it's important to remember that this is hydrogen we're talking about and the energy it takes to boil it is very small, so it's not actually a huge amount of heat we're needing to pull out here. The energy released by the conversion of one mol of orthohydrogen to 1 mol of parahydrogen is only enough heat to raise the temperature of a kilogram of water by 0.35 kelvin.

Should we invest in an automated factory ship that lands on a planet to construct a colony and paraterraform it based on it adjusting to its environment?
For example, it lands on Mercury, determines that the most habitable places are at the poles, strip mines the planet to construct a first in colony. Then later more factories and towers to support an atmospheric tarp and factories to pump out a suitable atmosphere for an ecosystem.
When it's done with a habitable space, it sends out a ready signal for colonists to arrive

>>14550375

You're conflating the phase 1 NIAC concept with the DIU proposal, little is known about the latter. It's likely the isotope being considered has a much better specific power, otherwise it's worse than solar for operations around Earth and it would be of little use to the military. The tradeoff is that it becomes even more expendable or the battery must be brought to a reactor for recharging.

Manly would have interesting questions and know enough about practical engineering to know what to ask at least. Berger I think would be more interested in business and timetable questions. Unironically id choose one of the oldfag autists from ye old esefgee because they’d ask interesting questions about engineering going on with starship Now and future questions about practicality in terms of real engineering problems with transit to mars and building mars colonies.
>have you given thought to the form of long term mars habitation? There’s lots of talk of domes and tunneling and even some more out there ideas from Handmer - where do you stand on it?
>how serious of a problem do you see radiation being for deep space transit to mars and how do you intend to approach the problem?
>What do you think of the variety of nuclear propulsion programs under development today?
>Have you given any thought to the sorts of probes, telescopes and rovers starship would enable?
>What is the plan food wise for medium and long term mars habitation?
>how many starships would make the trip in a single mission?
>What difficulties do you foresee with man rating starship? What do you think the practical relationship to NASA will be regarding Mars missions?
Etc.
Maybe Mr Eager himself would be suited to it.

Shame we can't live in that timeline.

Was about to post the same comment. Something about these two personalities interacting would be so amusing to me. Maybe it is because they both don't water down exactly what they want to say while going about it in two completely opposite ways. Instead of

>hmmm dinosaurs and the light of consciousness ;D
>this space stuff is so quirky look at how tall this tall tower is guyzzzz XD

>>14550252
I just play without any regard to spaceflight history or time. Lately I've been cheating by warping to LEO and pretending I did orbital refueling rather than do boring tanker launches.

Nuclear thermal sucks in KSP RO even with tanks far lighter than what can be made in reality and no multi layered insulation. I wasted so many science points on that shit.

>Mr Musk, do you think that possibly, in the fuwture, humans on mars might have to survive by eating thewr own recycled feces? Perhaps while their wife watches?

not spaceflight related

>>14550767
This, don't try to bait /sfg/ it's gay to do that.

>>14550764

what are you talking about? lol

This year glorious China will finish the space station

Next year, chinese bases in the Moon. Mars will be annexed to China by 2030.

Don't they only have two modules right now?

I work at ULA AMA

What material would work to make a transparent tarp as to paraterraform Mars or mercury? Something strong enough to survive a good fraction of Earth's atmosperic pressure and can be made cheaply in large amounts

>>14550808
Why don’t you work somewhere more interesting?

>>14550808
Why don't you get a real job instead of sucking the taxpayer dry? Is Atlas V first stage full reusability now on the table after Bezos bought a bunch of launches?

>>14550808

Anything transparent, you can stack bubbles inside of bubbles and achieve any interior pressure with any strength of material so long as you keep the pressure differential between layers small enough.

Well the most important properties other than transparency are ripping behaviour and UV resiliency.
If a hole gets in there, it cannot rip open it needs to stop propagation and slowly deflate.
Idk enough about materials but probably some fiber-reinforced ultra-high molecular weight polyethylene.

Zubrin says plastic in case for mars. Lightweight and you can make it on mars once you get setup, or bring the right stuff.

>>14550861
>and you can make it on mars once you get setup
That's true of every material

>>14550861
Okay let me ask a schizophrenic homeless person what they think and get their input as well.

>>14550539
The Moon is close enough that we can practice staying alive on a foreign surface and still send rescue missions if something goes wrong.

>>14550870
Zubrin has a degree and tons of work under his belt. He's maybe a kook, but he does know his stuff.

>>14550861
Well yeah polyethylene is plastic.
I imagine you want basically a foil and then fibers welded to it to stop crack propagation.

Wait a couple of years for that and you could ask Musk directly.
