I wanna live on the moon bros

>>12554259
Here’s hoping that tomorrow’s flight will be a success.

In what orbit will there be refueling depots? GEO? Also assuming that Super Heavy is enough to put Starship in some orbit and then it will land on earth, then depots must be in in a higher orbit to make sense for refuellng?

>>12554268
What flight? Falcon 9 or SN9?

>>12554275
>the cost effective mars plan - by rube goldberg

>>12554272
Super Heavy won't put anything into orbit
it will get Starship above atmosphere
to get to the orbit you need to circularize, which is what the second stage is for

>>12554272
Why do you need depots? Each tanker can be parked in the desired orbit for the mission, fueled, and finally the actual starship to do the journey can get there to be topped off. Depots only complicate the entire thing because you have to place and maintain them everywhere. Single one is definitely not going to cut it unless it's optimal for one destination only and on top of that you need systems to for long term storage of fuels making it even harder.

>>12554274
Both, but mostly SN9.

>>12554275
this one is better

>>12554293
>it will get Starship above atmosphere
At what altitude approximately? 70km?

Also what do you mean by "circularize"?
>>12554301
Well, if the mission is to get to mars, then this desired orbit for refuelling will be the same for many starships?

>>12554264
Weaklet detected. I'll be enjoying that Mars gravity.

>>12554220
I like this, do the drop tanks come off or nah?

>>12554274
Yes

>>12554336
F9 separates around 80km, so ballpark around that altitude
>Also what do you mean by "circularize"?
you need get enough tangential velocity (aka orbital velocity) to match Earth's gravity and radius
if you were to fly straight up to 70km, you would fall straight back again
and because Earth is rotating under you you would actually fall many kilometers westwards
that's why F9 and SH boosters need to do a bit of curve to land back where they started

>>12554274
>SN9
anyone know what time it's supposed to happen?

What

>>12554463
Starlink?

>>12554462
Unless something goes wrong, it should launch tomorrow.

>>12554472
there was not explicit confirmation that static fire was successful though

>>12554301
There's no advantage to depots in the context of a single mission (to Mars, or anywhere else). But for long term, it makes sense to use depots because you can bunker propellant over multiple launches over a longer period, and then launch a bunch of flights during a given transfer window. Trying to do it without a depot would mean using way more Starships (that have to wait in orbit until they've given away their propellant), and most of them would be half empty. Then the actual mission vehicle might have to make multiple refuels before it goes, and any delays could mean (worst case) missing your window.
What we'll probably see is a slow evolution: first mission to Mars will be depotless, each tanker flying up and refueling independently. Once cadence picks up, you'll have a few dedicated "depot tankers" that stay in our permanently to take on propellant from other tankers and then refill the mission craft in one go. Finally, it'll start making sense to build a dedicated depot, which can have larger capacity and no need for launch/reentry hardware.

>>12554560
Looks like he knows the libs are about to seethe and has pinned this.
Also, "we have the money to go slow" is no longer an excuse. It's time for BO to deliver.

>>12554560

starship hasn't had to worry about funding for a while which is great. Literally a blank check program at this point.

Hypothetically.

How would I go around building a reusable linear aerospike that burns RP1 instead of Hydrox?

>>12554590
You just can't help yourself

>>12554590
If things were so bad that people with a long history of consistent success were suddenly getting poorer, that'd be incredibly worrisome. Not sure why you'd think that's a bad thing.

>>12554610
There is no good reason to ever use RP1 in a reusable vehicle. Subcooled methalox is like 70-80% of the density with better performance, much cheaper (at Starship goal prices fuel is approaching half of the launch cost, meaning an RP1 Starship would be around an order of magnitude more expensive to launch), more predictable combustion, much less fouling.

>>12554623

I'm the guy who came up with pic related. I wanted RP1 because it's easier to store in awkwardly shaped tanks in the launcher's fuselage and wings.

Yes, I know I forgot to draw the cargo module, so sue me.

>>12554630
Wing tanks don't make sense in a rocket, in an SSTO especially the dry mass ratio wouldn't even pay for itself. Hell, I don't think it's even possible to make an RP1 SSTO period. Maybe if it had an airbreathing mode like Skylon but the extra complication would introduce even more dry mass. SSTOs are dumb.

>>12554560
fuck Bezos I'm happy that his ex-wife ripped 20 billions out of his pockets

>>12554630
why would you want this. extra points for creativity though lol, this is actually being used in some cursed timeline

>>12554638

Like I said, it's not a SSTO, it's an air-launched TSTO. The giant rocket boat plane is suborbital, the cargo module is the second stage and is boosted to mach 6 just below the Karman line.

I'm a dumbass for not drawing the cargo module but you should get my point.

>>12554646
Why is it even a rocket in that case? It could be a giant scramjet, cut out the lox weight, switch to subcooled methane and cut out even more weight as well as most of the fuel cost (and even be entirely locally fueled from the air and water), and still reach the same speeds.

>tfw I didn't buy any TSLA a year ago

>>12554675
tfw I did a presentation to a college class back in 2013 about bitcoin, but never bothered to mine any bitcoin myself or even buy it for the novelty. I bet all my classmates think I'm a millionaire now. Rip.

>>12554660

I just don't like the logistics of having to switch between propulsion systems in flight.

Never mind that ramjets can't produce thrust at idle velocity.

>>12554680

>>12554678
>I bet all my classmates think I'm a millionaire now
Don't worry, I doubt they think about you at all.

>>12554698
I'm sure they think about the time they were told how cool bitcoin was back in 2013 and how they could have been a millionaire if they listened

>>12554603
It's good but it's not real money.
It could go down as quickly as it went up.

>>12554691
Hybrid ramjets are a thing, and you wouldn't need any switch to rockets with such a low first stage velocity. It would still be dumb, but the original concept is even dumber. RP1 is a terrible choice as fuel costs would be astronomical, engines would need to be taken apart every flight and you would never have the advantage of FFSC, and the aerospikes are entirely unnecessary as you don't have vacuum performance to be concerned about.

Made a video about firefly, they're actually kinda based. Look like they have the right idea, just lacking reuse. What do you guys think about 'em? Really exited for both Alpha and Beta, not to mention the moon missions.

https://youtu.be/NNZAlqpFNKQ

>>12554711
I'm well aware. But it's just play money and I'm practically desensitized from loss after trading biotech lol.

>>12554711
I wish more people would understand this, especially the people who think billionaires are simply earning shittons of liquid cash that can be taxed. If Elon had a salary in the billions maybe I'd agree with them, but that's not how it works.

>>12554674
exactly, and the tandem mirror experiment was a real fusion research program in the 80's so also a very nice real life reference

>>12554712

After reading this I'm starting to see why RP1 would complicate things so I'm open to using alternatives.

But I wanted aerospikes because the engines need to maintain thrust efficiency from (literally) sea level to 50km altitude. With a fixed wing HTOL you have the perk of being able to have a starting thrust-to-weight ratio below 1:1 so that can save fuel.

>>12554598
Forbes is month old. Lol. Musk had gone from 20b last year to 187b right now

>>12554727
Jesus how

>>12554724
Aerospikes flatten the performance curve across atmosphere and vacuum but as long as you're staying within either a more specialized bell nozzle will always outperform it. It'll outperform it most at a tuned point and less outside of that, but it will not be worse as long as it isn't doing two jobs.

Dubs and SN9 fuckin explodes

Tesla bubble. Most (90%+) of Musk's wealth is in Tesla stocks, which are insanely overvalued atm.

>>12554748
Musk is going to own most of the battery market in ten years and the battery market is going to a explode over that time. It's not that crazy if you know what you're looking at.

>>12554748
With all that capital now, Teslas growth will continue to increase at close to 40-50% a year for he next few years. There's even suspect that they might surpass that this year and reach 1m cars or close to that.

>Rocket Lab's Proton
I'm pretty sure it's called the Photon.

How long until we build and launch one?

>>12554771
yikes lol, electron probably got me thinking about proton

>>12554713
Cool to see a video on an emerging rocket company. The Alpha is pretty much just another rocket at this point, and though I'd love to see it succeed, I wonder what the long-term viability of it is. For their sake, I hope they can pull off a success with this launch or soon, because between RL flying now and Astra and Virgin flying soon, it's already getting crowded and more competitors are on the way.
The Beta as currently presented would've been a good competitor to SpaceX and ULA a few years ago for medium-size satellites, but not really now. Also, its design has been constantly changing (from a three-core Alpha to a single-stick with AJR engines to a single-stick with in-house engines), so it seems pretty early in development. I'm pessimistic about it flying.
I knew they were already diversifying into other space systems, but the plans you showed look cool. Hope that works out for them.

>>12554771
Beck should go buy a surplus Proton to complete his subatomic collection

>>12554809
Imagine a Proton launching from Mahia

>>12554741
SN9 will stick the landing

Check em’

>>12554736

I also know that Aerospikes that burn RP1 do exist but they're much smaller plug nozzles rather than linear spikes like on the X-33.

I also took the idea from the sea dragon to use propellant extracted directly from the adjacent seawater by electrolysis.

I'm going to have to do some serious rethinking on this entire concept but I think if I really bust may ass I can get it right. We need an ultra heavy reusable launch system.

What would be the process for buying a dozen SCUD missiles (sans warhead) from the Republic of Egypt for research purposes? Asking for a friend.

>>12554859
Egypt probably wouldn't risk selling them to non state actors. North Korea and Iran would be your best bet, as they're in the process of modernizing their missile arsenal, and have no qualms with supplying weapons to terrorists.

Does Musk legally have to give the DoD access to monitor all Starlink traffic because of the PATRIOT ACT? I wonder if there's going to be a whistle blower about that, or if he's personally involved in that in any way.

>>12554889
Patriot Act is dead because Trump refuses to sign on the bill to fund it. Biden will have to activate it again consciously rather than merely maintaining it

>>12554630

what equipment/facilities would one need to live on Mars for at least 2 years before another rocket can get there?

>>12554321

>>12554924
Sufficient life support and reliable power are the obvious concerns. You may or may not need food production as well, depending on how much you've packed.

>>12554924
You could land a starship and live inside it for two years with just a handful of EVAs to set up some infrastructure and retrieve supplies from your cargo ship. But if the goal is to set up a colony you're going to need a lot more stuff.

>>12554889
Wouldn't it be more because it was launched on a rocket than the payload itself being relevant?

>Standard missiles (anti-air, anti-space, anti-missile, and anti-ship family of missiles)
>Tomahawk missiles (require no introduction)
>ASROC (anti-submarine torpedo carrying rockets)
>and many more!

>>12554972
There isn't really any reason to. Plus with gliders there's no backup if the arresting wire is missed or snaps.
Maybe if we ever got a spaceplane that landed under jet power, but then you would be able to just cruise it to a runway.

>>12555022
And also radio waves.

it's crazy to think that musk's most potentially profitable project, starlink, is already in beta testing.

>Musk does a cheeky Starlink IPO at the bottom and makes is all rich

>>12555033
Is starlink going to public stocks?

>>12555045
they said they were going to spin it off and take it public a while ago, but then quickly walked that back. I think it would be stupid not to take it public after Starship is up and running and capable of filling out the rest of the constellation very quickly, but it's not like Musk needs the money at the moment so who knows. Maybe there are SpaceX investors who would want to pressure him into it since it would make them as absurdly rich as he is almost immediately.

>>12555051
>they said they were going to spin it off and take it public a while ago, but then quickly walked that back

>>12555088
the sort of rounded pyramid shape is pretty sexy

what do you think will happen to roscosmos?
they seem kinda hopeless, spacex can get crew to the iss far cheaper and the f9 in general is much cheaper. i think their only hope is probably gonna be NASA having the soyuz in case crew dragon or starliner (lol) aborts or has a delay or something.

>>12555085
Not him but it's for the proposed space force point to point version for cargo. It's still retarded since putting VLS lengthwise would tip it over if you used it even ignoring the tank space that would be used up

>>12555022
It could store its heat in heat batteries and perhaps radiate it away after it reaches the far side of the earth, given the already high value and size of the thing. Also, I'm guessing that its deployment time would be relatively short, preferably on the far side of earth to help avoid detection

>>12555088

the biggest problem with that is that LA is going to become a warzone, Hawthorne is going to need to be shipped wholesale to either Brownsville or McGregor

>>12555253
Or the US military decides that Starship is so important to maintaining dominance despite the decline of the Republic that they declare Boca Chica a military installation and provide protection and funding for Musk's madness. Basically the Brotherhood of Steel, but with Starships instead of power armor.

The real tandem mirror machine, for reference. Not a plasma doctor but from my limited brainlet understanding it basically slams two jets of plasma head-on into one-another and then simultaneously fires a score of neutron beams into that center region, initiating fusion. The very uniquely shaped looping electromagnets are plasma mirrors meant to bounce cooling plasma coming from the core back into the region of fusion, however this was insufficient and eventually lead to the later Tokomak doughnut design and then Stellarator helical design.

nice. The current and up and coming smallsat market is really interesting. Btw for what it's worth I personally would watch a video breakdown of them all. Nothing too in-depth just a rocket comparison, like how Firefly is actually quite large (1000kg payload) and Astra is comparatively tiny. The problem here is that there are so many of them.

Actually nevermind I found a list and holy fuck there are a ton of these things: https://www.newspace.im/launchers . I've not heard of most of them.

>The last machine, the Mirror Fusion Test Facility was 372 million dollars, at that time, the most expensive project in Livermore history. It opened on February 21, 1986 and was promptly shut down. The reason given was to balance the United States federal budget.[11] This program was supported from within the Carter and early Reagan administrations by Edwin E. Kintner, a U.S. Navy captain, under Alvin Trivelpiece. Kintner resigned in 1982 complaining that the federal government had not provided the resources needed for the research.[14]

I red about magnetic mirror fusion the other day and this struck me as really odd.

A loss of power would interrupt the fusion but the pressure would dissipate immediately. Even more since this one is a SPACE engine.

>they're wrong about stocks having a rational basis.
very true. I see tesla stock people saying shit like "Elon sleeps in his factory... he's not an ordinary guy which means that Tesla is not an ordinary stock!" Shit makes no sense but this kind of thinking keeps their morale high.

>>12555088
Lockheed martin has always been my favorite oldspace company. Definitely the most competent of the bunch.
Now if only their lander wasn't fucking hydromeme

>>12555379
Clearly this is a sign that it worked perfectly and this had to hide this newly discovered supertech.

SLS is merely a decoy to hide that they have been building a Marsbase using fusion powered spaceship for a while.
It would annoy them if Elon came nearby, that's why the congress will kill the project on legal reason.
Gotta hide the Men In Black you see...

>>12555379
>This struck me as really odd.
It's honestly quite simple, the United States Government is an active and malevolent enemy to the United States citizenry, and is doing everything within it's power to annihilate any vestiges of freedom left in the country. That means all economic freedom, freedom to speak, to defend oneself, to move and travel and interact with other people unhindered, all forms of individual sovereignty.
Practical fusion power means an enormous and rapid reduction in the costs (and thus constraints) of electrical power for the average person and for independent industry, practical space travel similarly is the ultimate freedom of movement, the ability to literally leave an entire planet behind if you don't like it but can marshal the resources to get out.

They want us trapped here to become their slaves in perpetuity.

Thank fuck for this, page 8 of the actual document, objective 1.2:
>"The increased power demands of long-duration surface crewed missions and crewed flights beyond the Moon have led to consideration of surface fission power and nuclear propulsion technologies. Surface fission power reactors are envisioned to provide stable, base-load power to meet anticipated habitat and exploration missions on other worlds. Space nuclear propulsion systems offers advantages for exploration missions to Mars and beyond, including increased mission flexibility, mission abort modes, improved crew health and safety, and reduced mission cost."
>"DOE has a long history of advancing nuclear power solutions in support of the U.S. space goals. Starting in the 1960’s, DOE’s predecessor agency, the Atomic Energy Commission, actively designed and deployed the world’s first space reactor for use as a satellite power system (SNAP-10A) and also demonstrated nuclear propulsion technology through the NERVA program. DOE is well qualified and will play a critical role in developing and supporting future space nuclear power systems such as fission reactors for crewed base camps on the Moon, as well as space nuclear propulsion systems that may carry crews to Mars. Further, as with RPS, DOE will be able to take advantage of this space nuclear power R&D in the ongoing efforts to revitalize the U.S. commercial nuclear industry, leveraging commonalities in fuel design, material and component testing, and demonstration of small reactors to expand the use of technology to remote locations.

>>12555508
SpaceX but they haven't shared it
it's very dependent on the parameters of Starship during reentry (mass, CD, L/D, etcetera)

what the FUCK is this

>>12555520
3D PROOONTED nuclear reactor fuel element. Not some rando university project that will never actually accept fuel either, it's being done by ORNL.

The starship is a meme concept. Even if it does successfully flop on its belly on reentry, and even if the landing burn fully ignites and does its job of slowing the object down accordingly to what'd been planned, the debris upon landing pose too much of a threat to the physical integrity of the outer engines. The damage a flying projectile at such high speeds, flinged from the earth beneath the rocket due to the impacting thrust, could provoke irreparable damage to the outer layers of the starship, thus compromising the efficiency of its internal works. It's a flaw thats not avoidable in the slightest with our current technological capabilities.

The New Glenn, however, is immune to this phenomenon, as it boasts state-of-the-art technologically enhanced engines that put starship's thrust generators to shame.

A new era in spaceflight is enclosing on us. And it's coming to stay. The New Glenn will redefine the general public's notion of what is advanced tech. Be ready and fearful, for nobody is slowing us down.

So that's why it's painted black.

>>12555692
SpaceX has launched a lot of “competitor” payloads. Remember the Iridium launches from 2017? All of those went into an LEO constellation. Remember Orbcomm OG2? Also an LEO constellation. Not even including the dozens of geostationary comsats SpaceX launches yearly anyways.

That being said Viasat is retarded as fuck. However they’ll probably fly on an Ariane V

>>12555692

You do realize that you can still put a piece of proonted metal into a lathe and clean it up right? The difference is that you'll only need to clean it up, rather than having to drill and shape the thing out of a block many times heavier than the original part, while not being able to form all the same shapes a laser sintering printer can. Once more precise heads are designed for supersonic deposition printers you won't even have to worry about much cleanup, since supersonic deposition has no sintering and needs no heat treating or washing.

So did SpaceX actually do anything with those tank sections? Do you think they built some tanks and said “oh fuck this sucks.” We know of the 12 meter CF tank but that’s it desu. It seems like after the 2016 Announcement no word was made on BFR development until in 2018 Elon revealed that they built it out of Stainless instead

>>12555797
what pressure does current starship get to?

>>12555840
SNX, pronounced snex.

>>12555907
That's basically what happened, they figured out they couldn't heat treat a single tank, tried two COPV sections fused together, those blew up, tried sections with metal joining between them, that blew up, realized it was LOX embrittling and delaminating the carbon layers, so they dumped it and went to metals that performed well at cryogenic temperatures.

EverydayEstrogenaut makes great videos it’s just that he’s such a liberal fag that it offsets the neat visuals and information and whatnot.

>>12555965
yeah the history of these vehicles and that competition was really interesting

>>12556013

Thank God Trump admitted defeat. Now we can truly explore outer space

Angry Astronaut is kinda funny and I like how he shits on Blue and Boeing but on the other hand he seems to be a huge contrarian.

>>12556060

I think that if there ever is a pulsed fission rocket they really should actually call it the Chernobyl Drive, because what it seems like you're essentially doing is causing the core to go prompt critical for a tiny fraction of a second, it's constantly sputtering between almost dead and 20kMW/th output.
