Can a craft with a warp drive go directly through solid objects?

>>15136773
You can go directly through solid objects if you're stronger than them.

Help making a turbopump pls.
I was building a hydrogen peroxide rocket engine and everything was going great - The gimbal is working beautifuly, the aerospike nozzle turned out better than I expected and I was on the verge of victory.
But then the time came to work on the turbopumps, and it seems that I've hit a wall. Spiral centrifugal pumps are a pain to model in the software I use, 3d printed PLA isnt strong enough to resist high RPM (specially when submerged in liquid) and since I'm working with 20mm pipes anything I design turns out so big it takes 7+ hours to print.
I thought of making a sort of inverted car engine where the axis would spin, moving pistons up and down and thus moving the liquid, but moving multiple o-rings up and down would require high torque, which PLA cant handle.
Help pls.

to scale

Can you steal this guys design? Pretty sure he has models uploaded. https://www.youtube.com/watch?v=hko2u0558js

You should switch to ABS or resin ASAP.

>Can you steal this guys design?
I actually tried, but hydrogen peroxide with sodium hypoclorite create salt, which would clog such a small pump.

Inshallah WDR Monday

>>15136782
Watch some Agent JayZ and find the books he recommends to get your head around jet technology

>>15136782
I've seen PLA pumps on youtube and they work, but you're probably looking at high pressures if you want the rocket engine to work. First of all I suggest looking into the more 2d versions of pumps (pic related) because they're both easier to model and make. How did you make the aerospike? BTW it's a turbopump if it's powered by a turbine.

>>15136804
And here's a picture of compressor from a functional mini jet engine, just to give you some ideas. It's made from plywood and wrapped in carbon fiber around the perimeter. You could make something similar out of laser cut metal. Also designing a pump impeller isn't easy and you're best of just copying some existing design.

>>15136804
>How did you make the aerospike?
Using the probuilder add-on in the unity engine (you can laugh all you want lmao)

FUCKING LAUNCH ALREADY IT HAS BEEN 2 YEARS HOLY SHIT

>>15136773
warp drives are fake, this is like asking about how strong superman is, or how long it will take Russia to conquer the Ukraine (very and two weeks, fyi)

>>15136809
How did you manufacture it

>>15136773
No, it tears space apart such that objects do not maintain solidity at any level in warp space.

>>15136822

>>15136830
3d printing

Someone double check my math here but
If you clustered seven LE-9 engines on an SLS first stage you’d pretty much match the performance (you’d actually be running with about 300,000 lbf more than 4x SSMEs, but you’d have less isp the whole time)

Does spacex have any plans on testing methalox vortex engines anytime soon? A newer, shorter replacement for the raptor would be great for ascent/descent engines
https://ntrs.nasa.gov/api/citations/20010020208/downloads/20010020208.pdf

>>15136838
The ISP difference is fucking large though. You're effectively losing the effective of 10% of the propellant mass by making the switch.

>>15136852
Yeah and it’s a sustainer stage so that isp helps you out past the lower atmosphere. Although I think thrust fighting gravity is still more valuable than isp at the last stretch of the race

WDR Monday…for real this time…no more finding things to delay for another week…surely…this is it…no more nitro-cryos…this is the one…eventually…any day now
>Booster 7 rusting at this point

>>15136903
Ironically the HWNDU will be crying about billionaires and space travel. These guys are all the same.

When methalox is concerned, how feasible are airbreathing HTHL SSTO's? Technically speaking, something with engines that function as turbojets up to around mach 2, and then run as plug nozzle aerospike engines above that.

Pros:

>eliminates the need to build new spaceports
>can use most existing airports
>can self-reposition by flying itself from one airport to another
>can also function as a hypersonic transport from on point on Earth to another
>fully reusable with no major hardware expended

>>15136929

forgot pic like a dumbass

>>15136929
LITERALLY just do sea platform launched VTVL retard

>>15136929
Just build a SSTO with an RD-701 instead :^)
https://youtu.be/ctikrdo-2wQ

https://twitter.com/JennyHPhoto/status/1616102587962376192
neat

>>15136929
A few years ago, I had the idea for something similar but hydralox and SABRE engines

>at takeoff, use engines as rockets to get up to ramjet speeds
>switch to air breathing, shoot upwards at 45 degree angle
>once you've yeeted yourself out of the atmosphere at as high a speed as possible, switch to rocket and continue climbing into orbit
>when you're done in space, burn in the opposite direction of your orbital vector and flip that shit around, and then ride the hypersonic descent back to your launchpad, using the aerodynamics to control it like a glider and using the engine in case you need to turn around or whatever

Looking back, it's a much, much shittier solution than a Falcon 9.

>>15136968
Somewhat related but has there ever been an instance of a rocket exploding, breaking, falling over off the launch pad etc. and a stage being recovered, refurbished, and reflown? I vaguely remember manlet talking about this in an older video but idk if it was just a fever dream I had

>>15137100
If it got announced as such in the Blue Book planning doc thing they just published, then almost certainly. I'm not sure just how serious we can take the sources I'm seeing talking about it on twitter right now. The previous names all had about the same level of fanfare.

>>15137100
Please no I don’t need to confuse this with my favorite guns

>>15136929
whats this obsession with SSTOs

>>15137112
Some people never evolved past the 1990s.

>>15137111
how's that firing pin bro

>>15137112
SSTOs only make sense if you need to be able to land on and take off from various stellar bodies without any infrastructure. And there are a lot more problems to that then just making an SSTO… and I can’t think of why you’d need to do that, at least in this century

why is it so hard in rocket engine ignition? You would think that for a chamber full of combustible gases a spark plug would suffice?

>>15137112
childish dreams

>>15137112
they're cool

>>15137169
Back on earth they kinda make sense if you just want to send crew to Low Orbit while minimising failure point and with minimal infrastructure

>>15137158
https://headedforspace.com/how-rocket-engines-ignite/

Uneven ignition -> uneven combustion timing -> uneven pressure -> damage to engines

>>15136997
I think the closest to a failure and reuse in the USA. Is the Atlas 1 failed to launch, control considered shooting it, but eventually it was recovered and flown. An anon here could hopefully remember more details / find the YT video interview. The falcon 1 tank collapse kinda counts. Some shuttle flights got lucky on return too.

So NASA isn’t serious about a lunar base are they?
I mean, HLS for Artemis III could function as a base, but the fact that NASA isn’t serious about it like they aren’t serious about mars is disappointing

>>15137207
they barely have funds for the first 3 Artemis mission

>>15137184
thanks

>>15137169
Pretty much.
What's the point of science if not to make science fiction real?

>>15137183
they make way more sense on almost every other planet except earth, hell starship will technically be an ssto on mars

Reminder that 1.5 stage vehicles can get to orbit

>>15137234
Even space elevators are possible on Mars
getting out of Earths gravity well is always going to be relatively expensive

Which one will the US land on? The Chinese are also looking at some of the same sites for their missions

>>15137248
to add to that simple reuse of the first stage that is now possible make SSTOs obsolete

>>15137248
The Space Shuttle

>>15137252
I wonder if this decision will have far reaching consequences. Like NYC is where it is now because some ship happened to land there early n shiet

ZERO-STAGE-TO-ORBIT (ZSTO)

>>15137252
Connecting ridge seems best. Lots of plots near each other

>>15137253
SSTO is meme-tier difficult on Earth and trivial everywhere else. Even from Venus cloudtops. We'll end up using ordinary rockets as SSTO by default when operating in the wider solar system, with a special cuck-booster when operating from Earth.

>>15137234
>starship will technically be an ssto on mars
Not technically. Literally.

>Artemis 3 sending the first poc and woman to the moon

Didn’t really care about it that much but then I found out only 2 astronauts will be actually landing

…

>>15137317
Can you combine them into one to save mass? A genderqueer bipoc?

>>15137322
>save mass
Send quadruple-amputee astronauts!

>>15137317
And the others are on the cuckshed gateway (which hasn’t had a single module launched) (the airlock is being built by the UAE) (it will be empty except during Artemis missions)

>>15137322
There are literally two black women in NASA's astronaut list who have been waiting for 15 and 30 years respectively for *any* flight, it's unlikely any of the two will be picked for Artemis 3's landing tho.

>>15137258

>>15137317
kind of depressing actually
making it somehow special and forced like this I think cheapens it quite a lot
"look at these monkeys we put on the moon"

>>15137327
Kek

>>15137334
this could be fixed by having a black man, a woman, and then 2 other people as well

>>15137334
This, just put Glover on the flight and don't make a big deal about it, the fact they do says more about them than anyone else.

>>15137327

There's nothing on the moon
Space is empty and not worth exploring

I know SSTO is pretty much impossible on Earth now, but what about 100 years into the future? Who’s to say something Skylon-esque won’t be working by then? Idk

>>15137334
I like it because it lampshades the absurdity. Putting a woman and poccer on the moon was explicitly a goal, so rather than pretending "haha we selected the best astronauts and whoops turns out to be a woman and a brown just like we demanded", let's send them up there like the symbolic cargo they are regarded as, then get back to normal missions afterwards.

>>15137346
>nothing on the moon
Good, that means no blacks

>>15137353
Haven’t you been reading the thread?

>>15137351
might as well be a teenager and an actual monkey

>>15137349
No point. SSTO is easy anywhere but the Earth. From Earth you just use a booster which lands back on Earth for reuse.
I understand the appeal of SSTO, particularly HTHL. You jump in your spaceship and zoom off into space. You don't need to rely on some fag launch tower or booster infrastructure. But this reality is possible from every other solid body in the solar system. You could even zoom of a Venus cloud city in one stage.

Imagine, if you will, Inverse Shuttle

>>15137327
Pretty much how I got to orbit during the early days of KSP's development

I wonder how long the FAA environmental report would be if this launch tower gets approved. Though, this would disturb the stratospheric ecosystem, one of the tardigrades' natural habitat.

>>15137467
the tower was just a scheme to gather enough paper to stack up to geostationary orbit

>>15137469
Why don't they simply stack towers on top of one another until the top is in space?

Didn't see this posted anywhere, Starlink made a deal with the biggest cruise company

So true

>>15137462
Kino. It hurts so bad to see what could be but never ever will be. I wish I could reach acceptance wrt SLS like erik but I’m still stuck in seeth

I was watching an old stream of an Ariane 5 launch with the smaller hypergolic upper stage they don’t use anymore; and the vehicle literally gets to 8.2 km/s at stage separation. Wtf that’s insane it’s almost an SSTO (plus boosters)

https://www.canada.ca/en/transport-canada/news/2023/01/government-of-canada-to-make-an-important-announcement-about-commercial-space-launches-in-canada.html

Canada is about to be making a big announcement about commercial spaceflight activities tomorrow, so I guess this means that they're getting a new spaceport. I have no idea what rockets are supposed to be launching from there, since the only people who have ever expressed any interest in Nova Scotia are the fucking Ukrainians and they're not going to be exporting Cyclone-4Ms any time soon.

>>15137498
Considering that the average height of a flight of stairs ranges from 8.5 ft to 11 ft (let's just grab the value in the middle, 9.75 ft = 297.18 cm), and that space officially starts at 100 km from sea level, if you were to use a stairwell at sea level you would have to climb at least 33,650 flights to reach space.

>>15137511
All 12 people in Canada will surely benefit from this

>>15137510
Nah, no fucking release clamps, no dodgy aerodynamics of coupled aircraft, just temporary formation flying and a fueling hose hookup

If you can think of a better way to float around pointlessly and mine useless carbon dioxide, I'd like to hear it.

>>15137526
No seriously, all these precarious half-stage maneuvers are less convenient and practical than a normal booster.

The only recover liquid fueled rocket stage before SpaceX was half of a Titan II first stage that miraculously survived re entry and crashing into the water after launching Gemini 5 into orbit

>>15137511
I'm guessing a new launcher flying from the MLS spaceport, like ABL, Astra, or an unflown meme launcher like Phantom.

What if they took SLS and put one really thick and stubby SRB underneath it as its first stage to use the hydrogen core as a pure second stage? Assume that the RS-25s would be capable of air-lighting.

>>15137535
The Big Ares

>>15137529
>both spaceplane and tanker take off from normal airfields
> this is just as inconvenient and inflexible as needing a launch pad

>>15137476

Reusable boosters make ssto unnecessary and less capable.

>>15137540
How is an airport in any way more practical than a launchpad?

>>15137535
A pair of SLSs as boosters for a Sea Dragon.

>>15137534
Astra doesn't seem likely to talk launches from anywhere until Rocket 4 is near completion. ABL is more likely, but I don't see what Nova Scotia could offer them that they don't already get from Kodiak, SaxaVord, and Cape Canaveral. I don't see any of the credible players lining up for this and this announcement seems too big for the meme VC scammers. It's weird.

I'm something of an Antarctica autist.

Recently, I was thinking, Starlink would be ideal for places like Amundson Scott station and Tristen da Cunha that can't get decent internet. How much extra effort would it take to get decent 24/7 internet on the South Pole for these use cases?

Don’t they use the NASA worm boosters for commercial/starlink flights from time to time?

>>15137548
There are thousands of airfields already in existence and so you don't have the objections about noise etc. that launch pads bring. You have noticed the battles SpaceX has had to fight haven't you? Then there's the e2e passenger transport a Black Horse vehicle could provide

>>15137548
They aren’t and actually take up more space. It’s just normie bait, convince people that they can do new things at familiar places. And it appeals to bean counters because you supposedly wouldn’t need to build anything new (ignore all the new facilities and fuel storage you’d need to build at any given airport, ignore that it would extremely disrupt normal operations especially at touchdown, ignore that launch conditions for a spacecraft are much tighter than for an aircraft)

>>15137570
Gwynne probably shot this down when she realized elon would just put memes on boosters and by the third flight they would be stale as hell. Imagine if we still had falcon boosters with doge coin and uganda knuckles memes

>>15137575
that would be based

>>15137379
abby zero g boobies omgomgomg mommy

>>15137560
If it's a new launcher moving in, this was Canada's initiative and not the launcher's. The Canadian smallsat market can't be that lucrative and certainly wouldn't offer unique orbits, but the government might want something to show off. ABL feels most likely, but I'm just preparing myself for the secondhand embarrassment if they went with something lesser.

They need more polar shells, and a relay to reach a ground station. When the laser system is working, it the relay can be almost anywhere on the planet.
South pole is probably easier than the middle of the Pacific, because they could easily build a relay station close enough, maybe at the tip of Argentina or Chile.

>>15137564
Assuming a government contract, since there's no way you could fund it at the $100 rate, a single launch in just the right orbit might get you 24/7 fairly shitty internet. It looks like there are some in fairly polar orbits. I don't know what it costs SpaceX for a Starlink launch, but maybe 1-2 launches. I doubt it's cost effective compared to terrestrial point to point backhaul or packet radio or whatever.

Pog. Now the antarthots can livestream their orgies

Reminder, there are 80 moons on Jupiter

The “half completion date” requirement for Starlink Gen 2’s constellation was pushed from late 2026 to December 2028. This is good as it gives SpaceX more time to get the constellation done

Im by no means a tankie and communism (especially modern faggot self-proclaimed communists) are gay beyond belief. But recently I’ve had an autistic fascination with the USSR. Especially their science sector. It’s so fascinating. They literally had the means to get to the Moon what fucking retards. Are russians genetically predisposed to run themselves into the shitter?

>>15137694
Doesn’t make you a tankie. Soviet and Russian stuff is incredibly fascinating. And yes, Russians seem to have some weird curse on their society where they approach greatness then flop at the last second

>>15137693
Also, Starlink V2’s constellation has expanded to 10,000 satellites. SpaceX this needs 5,000 Starlink V2’s in orbit by December 2028. At 50 per launch, this is 100 Starlink launches by then

>>15137693
Thats necessary because FCC had delayed the application by 2 years.

>>15137696
It works out in SpaceX’s favour though. The original plan needed 3750 Starlinks launched 50 a time on Starship by 2026, which is pretty optimistic. The new constellation can be launched by Falcon 9 too

>>15137671
Yeah, specifically about Amundsen Scott though, I'm not sure there are any satellites currently in appropriate shells. Big geostationary sats or what have you are probably cheaper, but I certainly wouldn't complain if SpaceX filled out shells for the north and south poles.

>>15137698
>>15137696
And also, the “half completion deadline” used to be December of 2024. 75 launches of Starship by then is wildly optimistic desu, but it explains why Elon ranted about
>”If we don’t have Starship flying weekly by the end of next year (2023), we may go banrkupt!”

>>15137702
>>15137698
>>15137695
Lastly, this pivot away from the original Starlink V2 sats that could only be launched by starship seems apparent in why Ship 24 and Ship 25 had their payload doors welded shut. No need to deploy satellites for a defunct plan (the new Starlink V2’s are Falcon 9 sized)

>>15137694
I am fascinated by china. I dislike them, I’d even say hate them, but it’s interesting seeing them develop a space program and try and survive as this weird quasi-isolationist yet coping communist state.

New book examining the old O'Neill colony concept using Starship. Instead of building them at L5, they're built at about 500km altitude with terrestrial industry. Afterward you can boost them wherever, but the cost and technical challenge is a lot lower if you don't have to build mining and manufacturing facilities on the moon before you start on the stations.

>>15137875
Apparently Starship is competitive with the going rate of building infrastructure on the moon. My bet is the most efficient way to do it is build a small colony with onboard refining and manufacturing hardware in LEO/MEO, then boost that to L5 to continue manufacturing there with lunar materials.

>That jamming reported in the media was normal GPS jamming on the front lines. Starlink's Dishy had used GPS to determine its location for pointing and uplink timing control. GPS jamming by Russia (and Ukraine) broke it in the first few weeks. One of the Starlink engineers then designed an algorithm to eliminate the need for GPS (using Starlink as a GPS instead) which solved the "jamming" problem.
wait starlink has it's own built in gps alternative that is jam proof?

Can the falcon heavy booster that is abandoned in the ocean be recovered? I feel like China could recover it if they knew of the launch and ballparked the crashing location. They would just need a submarine and maybe go for the Merlin engines. It's seems really irresponsible to let a booster go instead of letting it land like the others.

>>15137994
Yes, researchers have already done this by analyzing the signals without any help from SpaceX.

how will we cope lunarsisters? the literal best case full reuse scenario still is in the neighborhood of half a billion

What’s the X-37 even doing up there?

>>15138437
Honestly. The cope is going to be Starship limiting to the cost of fuel.
18 fully reusable flights could be on the order of $20M (huge cope).
Realistically landing on the moon is not going below $1000/kg any time soon. Keep in mind that is still assuming a massively reused successful Starship program and is cheaper than LEO currently is.

>>15138456
Tbh if Starship is $20 M/launch and it takes 9 or so launches to get to mars, that makes the ticket price for a crew of 25 $7.2 M/person

>>15138468
The issue with NTR is that it also requires a deceleration burn at mars, which adds another 3 km/s of burning. Aero capture + Chemical is way better. Also, NTR often uses zeroboiloff hydrogen propellant

>>15138458
I believe it can go below $20M but for every crew flight you will still be sending dozens of infrastructure payloads.
We can do great things on Mars and the Moon but the current Starship will still only take us so far.
We need extremely cheap energy for synthesizing fuel or better propulsion or both to go further.

Don't need fuel from Earth, just mine thorium and let radiation transmute it
>Ultra-safe nuclear thermal rockets using lunar-derived fuel
>A solution is to harvest fertile thorium on the lunar surface, then transmute it into fissile uranium using the gamma ray fog which pervades the deep sky. It is only at lunar orbit, at the very edge of cislunar space, that the Earth-launched machine becomes a nuclear thermal rocket (NTR). Thorium is not abundant, but can be concentrated by mechanical methods because of its very high specific density relative to the bulk of lunar regolith. Thorium dioxide (ThO2) has an extremely high melting point, such that skull crucible heating can be used to separate it from supernatant magma. When filled into a graphite-lined beryllium container (brought from Earth) and set out on the lunar surface, high-energy gamma rays will liberate neutrons from the Be. After moderation by the graphite, these thermal neutrons are captured by the thorium nucleus, which is transmuted into protactinium (Pa91). This element can be extracted using the THOREX process, and will then decay naturally into U-233 within two or three lunar days. The uranium is oxidized and packed into fuel pellets, ready to be inserted into a non-radioactive machine, which now becomes an NTR.

Large fucking chunks of where the map says China are foreign territories filled with people who don't even speak Chinese--some of them are not even ethnically Asian. What they all have in common is strict control by the central government that is used to ensure the stability of the current form of government, the rule of current leaders and the economic prosperity required to maintain stability and enrich those with power. China has its hands everywhere in international politics, far outside its borders, and of course its economic impact is global. Not only that, but there are Chinese people living in large numbers in every (?) country on Earth that the PRC considers citizens, regardless of where they were born. Don't forget Chinese development projects in third world countries.

In short, the PRC is the exact opposite of isolationist.

...What? Do you think people are going to run ICE engines on Mars? In your head, how is that going to work?

>>15139022
Zubrin has proposed Mars vehicles powered by ISRU synthesized hydrocarbons and oxygen for the advantages of IC engines. When you try and imagine electric bulldozers etc. he has a point.

>When you try and imagine electric bulldozers
Infinitely superior to internal combustion bulldozers in every way imaginable? Electric motors make peak torque at stall, they absolutely destroy diesel engines for work exactly like a bulldozer.
>M-muh batteries
3.7 m/s^2, it needs all the weight it can get.

>SpaceX employees say they are relieved Elon Musk is focused on Twitter because there is a calmer work environment at the rocket company
>Current and former SpaceX staff, who requested to remain anonymous, told Bloomberg that they didn't require Musk's attention every day. Following the billionaire's takeover of Twitter in late October, there has been a "semblance of calm," when Musk is focusing on other activities
>Musk's engagement in daily operations at SpaceX could create more work for staff, per the report. His demands for changes to hardware sometimes result in another redesign, staff added.
>For example, Musk had previously ordered random changes to suit his preferences, such as staff redesigning technical hardware due to its aesthetic which can take weeks to achieve, current and former employees told Bloomberg. His demands have sometimes led to staff reworking the product again for its functionality, they added.
uh oh

the weight of tje batteries is a big factor in range when it comes to electric vehicles so driving on a planet with a third the gravity makes them way more viable

There is air on mars. Just not oxygen in the air.

>>15139043
I concede the bulldozer point, I can't remember the use cases Zubrin actually proposes.

Ya don't obsess over them, until one of their Young global leaders becomes your country's PM

Canada's announcement is... launch regulations.

lmao, what else could have been, pathetic

Tractor configurations do have some advantages, tensile structures save weight

My schizo bad, mostly for manufacturing products and certain industrial process, but yes ev are still idiotic, what are you go going to do with a big mining machine that last like 20 min and have to be recharged for 6 hours?
