It kills me that it took humanity so long to make use of such a basic fuel for rocketry. Methane is barely even mentioned in "Ignition!" for example.

Zhuque-2 is noteworthy not because it is methalox but because they managed to make orbit without a solid motor stack provided by the government.

>>15557868
worked for the first time but I think it got overloaded in 5 mins
there is not much more info on the site than the screenshot

>>15557871
but how much of it is just Chinese academy of sciences hand-holding?

>>15557871
There was one liquid propellant rocket that got to orbit from another chinese company, but I think it was RP-1

did they really develop and manufacture successful methalox engines in 18 months?

the engines looked great btw with the identical mach diamonds, you can tell they're firing perfectly. What a beautiful launch

>>15557880
>id they really develop and manufacture successful methalox engines in 18 months?

They finished developing an existing design.

AI is kinda needed for future anyway. Musk has talked about AI for the last decade. Tesla/Neuralink are already AI plays.

>>15557925
Soyuz-5 was a RKK Energia project that they tried to force Moscow and Roscosmos to show financial interest in. S5 couldn't launch from Vostochny, there's no real advantage in launching a GTO optimized Zenit-clone from a polar site like Plesetsk, and Moscow has been pulling away from needing launch sites in a foreign country ever since the wall came down. Soyuz 5 has been the next best thing to dead for nearly a decade.

>>15557955
>>15557949
the boring company has been making some progress recently too, boring machines surfaced infront of two new locations in las vegas and a prototype autonomous car like pod leaked (which has been shown in renders before, but this was an early physical prototype of some sort)
I don't think these really slow him down too much though as he isn't personally designing the boring machine or neural network architectures day-to-day and I remember from some interview that he uses like 40% of the time at tesla and 40% at SpaceX (or 45% each) and has been doing this for quite a long time with other sidehobbies
X.AI exist basically because OpenAI (which Musk was co-founded and gave money to) went into a direction he didn't want
that was at the end of 2015, doing stuff at multiple companies or other entities is not new and people whining about twitter are retards that haven't really followed what Musk is doing

Tianlong 2

China has lapped russia in terms of space capability—I cannot deny this truth any longer

>>15558010
> Tianlong-2, another launch vehicle designed by the company, entered service in early 2023.[4] It is 32.8m tall, and it can lift up to 2t to LEO and 1.5t to 500km SSO.[5] The maiden flight of Tianlong-2 took place on 2 April 2023, successfully carrying the Jinta cubesat from Hunan Hangsheng Satellite Technology to a Sun-synchronous orbit. This mission represented the first successful launch of a Chinese privately funded, liquid-fueled, kerolox rocket with Space Pioneer becoming the first startup company to reach orbit on its maiden attempt.
> 2t to LEO and 1.5t to 500km SSO

>>15558018
didn't that happen a while ago, China is exceeding Europe too now and would probably exceed the US if SpaceX didn't exist
India will probably be "third", both Europe and Russia becoming irrelevant

>>15558018
Same thing happened with nukes. China the was fastest country to go from a fission bomb to a fusion bomb. They just weren't as interested in stockpiling as the US or soviet union was (that we know of)

>>15558024
Despite having to fall back on their domestic needs they're still putting a reasonable amount of mass into orbit. Russia has nine more protons to launch over the next seven years and they don't seem to have much trouble launching a double-digit number of Soyuz-2s every year despite everything that's going on. They're not going to be doing much that's big or exciting but they'll keep on lofting Kosmos payloads with their usual Slavic inertia.

Why are there so many third world subhumans in these threads recently? OP is one clearly.

https://www.space.com/artemis-4-5-moon-missions-european-astronauts

>>15558024
yeah, in terms of launch rates, China's rise started in 2010 and accelerated in 2018. Russia's decline started in 2015 (coincidentally?)

>>15557934
Using about a dozen people with full-cortex neuralink implants and a supercomputer to network them and parse the output, you could make a brain-telescope that observes the causal layer above the universe. I wanna go try to pitch it to them and get tossed out of a boardroom.

>>15558072
E*rope is doomed to a future of being passengers and followers in space endeavors. Are there even ANY European orbital launchers now that Ariane 5 is out the door?

>>15558095
Soyuz is verboten and Vega keeps blowing up stages, so no.

>>15558089
I think that is literally the longterm point of Neuralink, merging with AI and the starting pitch of X.AI (understanding reality)

landspace reached orbit 8 years after founding, 2 years slower than SpaceX but with a much bigger rocket. I think they'll become a big player very quickly

>>15558111
Kek based

After some researches I can conclude that this is the design evolution of Ariane 4’s first stage and boosters, the S2 and S3 were unchanged

(Number is propellant mass)

1976: First Ariane 4 studies (interesting, always heard A5 studies came before

Spring 1979: L180 or L200 4-Vikings + 4 PAP 7.3t ; 3,300 kg payload (2,900 dual launch)

Summer 1980: L220 5-Vikings + 4 PAP 8.5t; 3,900 kg payload

By Spring 1981; L220 5-Vikings + 4 PAP 12.6t; 4,080kg payload

Later in Spring 1981; L190 4-Vikings + 4 PAL 42.5 (not-jettisonned) or 4 PAP 7.3t ; 4,190kg payload

June 1982: L220 4 Vikings + 4 PAL 36 (jettisoned & recoverable) or 4 PAP 9.5t

Some time in 1983: L220 4 Vikings + 4 PAL 39 (Jettisoned & unrecoverable) or 4 PAP 9.5t

Picrel is a drawing of the 1981 variant, the first stage L190 (vs L220 final) is noticeably shorter compared to the boosters L42.5 (vs L39 final)

Most of this comes from A. Souchier (Ariane 4 propulsion director) or R. Vignelles (Designer of the Ariane S1, Director of launchers ar Cnes in the 80s) writing

>>15558111
its true

Excited chinamen

Who is most likely to be the next company to make a Starship clone?

The chinese are working on 3, I imagine some other launch manufacturers want to get in on super heavy launch

>>15558110
I don't think it's something Ukraine would consider for at least a decade post war.
For Turkey it would probably be a bad deal, basic contributions are based on GDP. Turkey has a fairly large GDP, but their industry and research are pretty behind to actually exploit the benefits of membership. There is also no way in hell they would be accepted with Erdogan still in charge.

>>15557968
>medium lift rocket carries more than small lift rockets

anon...

>>15558162
could be any company at this point depending on how they execute on the falcon 9 clone
I guess it could even be a completely new/unknown startup, but doing a Starship clone directly before a smallsat launcher or Falcon 9 clone seems almost impossible

>>15558162
I doubt anyone seriously considers Starship clone before Starship actually works, funnily enough it will be too late then. Just like it is happening with Falcon 9, at this point Starship will be flying before F9 clones start flying.

>>15558113
>landspace
weird name for a space company, maybe it sounds better in chinese

>>15558218
Their chinese name is blue arrow
(蓝箭航天空间科技股份有限公司)
I think the logic is something like "From land to space" but yeah it sounds bad

>>15558227
Blue Arrow sounds so much better.

What's the latest from Kopernik Shores?

>>15558162
Many will try. I suspect over the next ~10-15 years the only things that will even come close to SS will be Long March 9, and perhaps New Glenn with a third stage? I can’t think of anyone else who even has the capability except for India but that shits going to take even longer than LM9 which is already as slow as molasses in january. ESA and JAXA have the theoretical capability but that’s not happening

>>15558167
china is ahead of 99% of american rockets

>>15558256
Either Blue Arrow or Lanjian Aerospace if you just want to try pronouncing the original Chinese. Anything's better than Landspace.

>>15558265
But not the 1% that count.

>>15558265
Yes a medium lift rocket will carry more than 99% of small lift rockets.

Would be funny if it was Rocket Lab, constantly trying to stay in their niche but being forced by SpaceX to keep up
>Neutron comes online
>Fly it a couple times
>For fuck's sake, SpaceX is absolutely mogging us again with Starship
>Fine, get the blender, we're doing heavy lift ourselves since nobody else is going to
Unfortunately even if Neutron works well and soon enough and they keep it going while developing something big I don't think they'd have enough funding and all the VC money is still gobbled up by SpaceX or going to sexier companies like Relativity.

Realistically though the startups probably can't afford it even if they wanted to and the institutionals are too slow or can't get their governments to fund it. Bezos might be the only one actually capable of doing it.

>>15557791

not surprising but what about japanese astronauts? if a canadian is on artemis 2 and euros are on 4 and 5, then are we getting a japanese on artemis 3?

>>15558319
maybe, I still think it is too early to tell if Rocket Lab, Relativity and Stoke are going to die
Rocket Lab has the side business of doing satellite buses, which is going to grow alongside Starship going online (assuming something like a general satellite bus that outcompetes everything else becomes a thing like one of the scaremongering articles was talking about with respect to starshield)
the bus side of the business could keep them afloat until they build the Starship clone

>>15558162

His job is probably site supervisor or procedure manager or something like that. I know a guy whose entire job is to just watch people all day long while they work near heavy machinery to make sure they follow procedure and also act as a witness. He doesn't have a supervisory role, he doesn't have anyone explicitly under him, but he is the safety manager.

Stokes is not convincing
>Hydrolox despite volume constrained S2
>Not a cylindrical S2 like starship = shit mass ratio
>Quasi-Aerospike so vacuum isp will just be good, not outstanding
>Underwhelming S2 performances means payload will drop quickly with higher energy orbit.
>Expendable S2 will bring less payload increase due to the way it’s made
>Underperforming reusable S2 + Light hydrolox fuel = S1 will Provide more of the dV
>higher S1 staging speed = either more reentry burn or shielding (Dow range landing) or exponentially more boostback fuel (RTLS)
>S1 supposedly high performances FFSC methalox engine That’s yet to be proven


I do commend them for trying to do a full RLV and directly aiming the medium launch market

Honestly if they CAN make that S1 I fully expect them to drop that S2 architecture
If they can make that S2 but not that S1 well they’ve got a useless rocket

>>15558331
The problem is you need billions and billions of money. Satellite buses and Neutron aren't going to make Rocket Lab or anyone that kind of money and investors aren't going to give it to Rocket Lab until Starship shows likelihood to actually have a decent market and most would rather give it to SpaceX at that point. Even SpaceX can only afford Starship because of frequent investment rounds and all the NASA money. I really hope someone gets to compete with SpaceX lest they become complacent but I just don't see how unless Jeff actually gets off his ass and leads BO full-time.

>>15558352
That's why I both say they'll see pressure from SpaceX to compete better and that Neutron is far from a certain success. I think they have the most solid footing of the also-rans but they're far from safe even without Starship. If Neutron was coming sooner they'd maybe have a chance of profiting from Vulcan's constant delays but it'll probably be just too late.

>>15558373
I still haven't looked into Stoke because they seem like such a meme

>>15558373
Honestly hydrolox capsule-like reusable S2 sounds straight out of the 90s. It could work but it will be subpar, it seems they’re trying to compensate for it with a state of the art S1

>>15558374
SpaceX only becomes complacent when Musk stops firing people and eases off how hard he works the employees. If those two things never stop then they will never become complacent.

>>15557934
He really needs to lay down the ketamine and other drugs

>>15558024
imagine if US tried to compete with Atlases and SLSes with China

>>15558378
That's a hope and may well be true, but it would be better to actually have a competitor that forces them to not get complacent instead of relying on the whims of a single man.

>>15558304
That's a really cool photo

>>15558387
Yeah but we both know that won't happen. The crazy bastards out there who might won't get the chance because they don't have the means. And the people who have the means don't have the will. It'll just come down to a knife fight between SpaceX and China until AGI kills us all.

>>15558407
they pretend you can cram 7 stinky niggers in there so the theoretical cost per nigger is under budget

Dragon doesn't fly 7 people either

>>15558373
Every single one of these points is off the mark.

>Not cylindrical
because the second stage is capsule. Are you going to complain about Dragon not being a perfectly optimized soup can?

>Quasi-Aerospike
So they can use their actively cooled heat shield to run their expander cycle engines. It's solving two issues that occur at the same time.

>Underwhelming, Underperforming
By what standard?

>Expendable S2
The whole point of the rocket is that it's completely reusable.

>higher S1 staging speed
Oh no! they'll have to engineer for a higher thermal load. whatever will they do?

>high performances FFSC methalox engine That’s yet to be proven
This is the closest you come to a valid point, but it's not like FFSC engines have never been built before.

>>15558373
Yes all their problems come from hydrogen

>>15558430
Higher staging and thus first stage velocity means that RTLS is no longer an option (higher operational costs) and more of your limited mass budget going to thermal protection (lower payload).

>>15558430
>because the second stage is capsule
jesus man the further away from a ball or a cylinder the heaviest the structure is, that's basic stuff

>Quasi-Aerospike
they'll be having expander cycle and settle for 440 isp. They wouldn't have had these two issue with a normal cylindrical lifting body

>By what standard?
by the standards that TSTO at such a small scale is REALLY sensible to any additional dry mass, they're likely at least halving it just to reach the usual SSO, based on some numbers I've seen people speculate.

>The whole point of the rocket is that it's completely reusable.
That way of thinking works for starship, not for a medium scale launcher, they'll be kept out of segment of the market if they can't adapt their performances to the payload.

>Oh no! they'll have to engineer for a higher thermal load. whatever will they do?
Downrange means longer recovery time, doesn't work that well with a fully reusable rocket, RTLS means more fuel expended, there's no engineering around that,

>>15558453
I'm not saying it won't work, I hope it works, I just believe it's not the optimal way to look at medium launcher TSTO full reuse, and that they will have to compensate for that S2 with a REALLY good and large S1.

A major agreement on space exploration is to be signed between Russia and African countries

Yuri Borisov, director of the Russian space corporation Roscosmos, who is visiting Egypt, said that the signing will take place during the second Russia–Africa summit on July 27-28 in St Petersburg.

According to Cherif Sediqi, president of Egypt's Space Agency, this is not a bilateral agreement between Russia and Egypt, but a document that should be concluded at the level of the African Space Agency (AfSA).

In addition, Russia is ready to assist the member states of the AfSA in the construction of space centers and the development of their own range of launch vehicles.

"One day, Egypt and the African Space Agency will probably have their own cosmodromes and a complete family of launch vehicles. We are ready to help you in this area," the Roscosmos CEO said

Curiositys wheels continue to get fucked up

https://www.nytimes.com/2023/07/04/business/india-space-startups.html

short article about the space startup scene in India from 4th of July (posted in full below)

> The Surprising Striver in the World’s Space Business

>With at least 140 registered space-tech start-ups, India stands to transform the planet’s connection to the final frontier.

> When it launched its first rocket in 1963, India was a poor country pursuing the world’s most cutting-edge technology. That projectile, its nose cone wheeled to the launchpad by a bicycle, put a small payload 124 miles above the Earth. India was barely pretending to keep up with the United States and the Soviet Union.

>In today’s space race, India has found much surer footing.

>In a sleek and spacious rocket hangar an hour south of Hyderabad, a hub to India’s tech start-ups, a crowd of young engineers pored over a tiny, experimental cryogenic thruster engine. The two founders of Skyroot Aerospace, talking between blasts of hissing steam, explained their exhilaration at seeing a rocket of their own design mount India’s first private satellite launch last November. These new thrusters will guide Skyroot’s next one into orbit this year, with a much more valuable payload.

>>15558586

>>15558627
Yeah basically what the other anon said. It’s fun seeing them take a beatdown yet still work. Like yes, in retrospect JPL looks retarded for making a dumb engineering choice, but the wheels aren’t broken beyond repair so there isn’t really a problem

>>15558639
>but the wheels aren’t broken beyond repair
anon...

>>15558608
Do you think they smash up the wheels on the spare back at jpl so that it continues to match handling?

So this is basically the equivalent of Vulcan, SLS, Starship and Falcon Heavy?

>>15558644
this is actually a good question

>>15558649
Yes on the last three. I don’t understand your Vulcan comparison though

>>15558608
I will always wonder what the choices were behind those wheels. They looked flimsy to me on day 1, but I though surely they must've thought of that? No, they actually break and now they drive backwards. I suppose they were enough for the intended mission length, but you know these always get extended, imagine if it couldn't get extended because your team's stupid wheels fail before the rest of the rover.

>>15558642
>>15558658
Wait hold up, are the wheels THAT messed up?

>>15558654
Vulcan can also do the 4 side boosters

>>15558658
they thought they would not wear down so quickly and the reason to choose flimsy wheels was mass autism

article from 2014 doing a deep dive into the wheels (this was linked to in the orbital index weekly issue)
https://www.planetary.org/articles/08190630-curiosity-wheel-damage

>The skin of the wheel is 0.75 millimeters thick -- the absolute thinnest that could be machined.

>>15558668
I can certainly understand mass autism, but you'd think they'd spare a few grams to make sure the wheels can definitely take a beating even over what you think should be fine.

>>15558668
>>15558687
OK damn I didn't realise how big these wheels are, it makes more sense now, but still.

1/16th of the first stage thrust is wildly undergunning it on Relativity's part. Falcon 9 is a little better than 1/9th with MVAC compared to the sea level Merlin, and Starship is starting at 1:5.5 of the booster's thrust, going up to 1:3.7 with a nine-engine Starship.

its a thing, basically means longer conversations with ChatGPT-like chatbots that have been prompted to play some kind of role tend to become deranged/bad, the short argument for this was something like: there are only a few ways you can prompt to be sane and diverging from this path means the bot starts to emulate something that is not sane as chatbots are basically playing some personality when you ask them something
bings chatbot is prompted with a long list of stuff like you are a chatbot called sydney, you are helpful etc
an analogy would be lets say you have a spoon and a plate of ice cream
most actions you can take with these items are deranged, only a few actions are sane (use the spoon to eat the ice cream)
throwing the ice cream at a wall, smearing it on your face, stabbing your eye with a spoon etc whatever, almost anything you do is insane except eating the ice cream with a spoon

>>15559238
Honestly impossible to tell at this point, but probably not like that and certainly not in those timeframes. I'd say it depends a lot on how well and quickly SpaceX and BO execute their HLS programs, if SpaceX has multiple HLS and private Moon missions under their belt while flying Starship commercially regularly and BO is getting there for HLS at least I could see SLS get very hard to defend even for Congress. But if SpaceX is just barely managing to get HLS ready for 28 or later because refilling, reentry, and HLS Starship design take far longer than hoped, SLS might stay around for a while.

Gov't regulations are fairly scary. But if they're too onerous, there's at least one backup plan: Launch from the oil platforms. I know SpaceX got rid of Deimos and Phobos (https://spacenews.com/spacex-drops-plans-to-covert-oil-rigs-into-launch-platforms/)), but that was because they didn't have all the features they needed. A purpose-built offshore platform could be used for launches in the middle of nowhere. Potentially it could have undersea methane and oxygen pipelines connected to it.

there is a thing called outbreeding depression
from a population increasing standpoint, the highest fertility is between people who are like second cousins or something like that
not close enough for inbreeding to be a problem, but not far away enough so there are weird mismatches and especially stuff like not being suitable for the environment of either parent (this might not be as big of a deal as it was previously, but there are other factors than just not being suitable for the environment)
diversity is often touted as positive due to people being brainwashed to believe it automatically results in diversity of thought
it doesn't

A few times I have seen people try to refute and deboonk the claim that the Shuttle had a large delta wing because the military wanted cross range capability for polar orbits. Who is it spreading the idea that this is a myth? Is it Scott Manley who's telling people this isn't true?

Because I'm watching the MIT OCW video lectures of MIT 16.885J, Fall 2005, and they've got a bunch of old Shuttle guys giving presentations and they're all asserting the supposed 'myth'; the big delta wing was for cross range capability so the shuttle could do a single polar orbit then land back at Vandenberg:
> Because of the military requirements, we had to change our specifications. And this became another one of the elements that drove the final design. The military wanted a 60 foot long payload bay. It had been 40 in the designs that we had been doing so far. They wanted 40,000 pounds Polar, and that made our due east payload up to about 65,000. That was a big change from 20,000 to 60,000. And they needed 1,500 [miles] cross range. They wanted to be able to go around the earth while the earth turned and land at the same spot. So they had to have 1,500 miles of crossrange.
https://youtu.be/iiYhQtGpRhc?list=PL35721A60B7B57386&t=2696

>>15559681
That quote is from Dale D. Myers btw.
Later on in the lecture series, Aaron Cohen reiterates the same point. Both of these guys would know better than whatever internet jackoff is spreading a deboonking.

>>15559681
>>15559684
And here is Jeffrey Alan Hoffman explaining the same point:
>>>/wsg/5181311

>military wanted large crossrange for polar orbits
>that necessitated the delta wings

>>15559681
Who is saying.
What are they claiming the reason for the large delta wing is then.

>>15559692
All these old shuttle guys are saying the big delta wing was for military polar orbit missions. I don't know where the contrary claim comes from and I can't point to a specific instance of it at this moment, but the counter argument goes something along the lines of

>nuh uh, they chose a big delta wing because they just did okay. the military had nothing to do with it. nasa built it exactly the way they wanted it and the design wasn't in any way compromised or otherwise influenced by the military

No one cares about obscure sh*ttle faggot lore. Kill yourself.

>>15559693
Unless he changed his mind that doesn't come from Mr. Manlet
https://youtu.be/_q2i0eu35aY?t=70

>>15559695
Elon-sama, you should have watched this lecture series because they're talking about how getting tiles to stick to the orbiter was the hardest part of the entire project.

>>15559681
Sounds funny, because it's common knowledge to any spaceflight interested person at the time military and congress fucked over the initial shittle drafts possibly turning it into the deadliest manned vehicle for no real practical reason (that we are aware of, which might be important, I suppose)

>>15559703
>(that we are aware of,
Well it certainly never flew from Vandenberg, they wouldn't be able to hide that. It did have classified missions, but none to polar orbit.

>>15559693
https://twitter.com/waynehale/status/1331230062876778501
>The huge re-entry crossrange capability of the shuttle - which was a direct result of the requirements of 3B - was extremely important and used every single shuttle flight - even it 3B itself never flew

I can see this turn into an argument: since crossrange was so important the design would have evolved towards that even without the military requirement.

>>15559708
According to these guys, NASA was planning for 400 miles crossrange and the military wanted 1500 or 1100.

>>15559701
>because they're talking about how getting tiles to stick to the orbiter was the hardest part of the entire project

Turns our gluing unique micro thin shapes onto a fabric sheet is a shit idea, shocking. Kill yourself boing locksneed nigger

-X

>>15559710
The problem was mainly the thermal expansion of the aluminum structure of the orbiter not matching the thermal expansion of the tiles. The 'fabric sheet' was the solution to this.

>>15559712
Wow it's a good thing that steel has a thermal expansion coefficient three times less than Al*minum then you stupid reddit faggot huh?

>>15559722
>Al*minum

>>15559681
https://history.nasa.gov/SP-4221/ch5.htm

The cross-range was an accidental by product. The real reason they went for it was because it had better handling capabilities across the supersonic regime, and eliminated the need for a suicidal nose dive that Max Faggot wanted with his straight wing shuttle.

>Draper did not accept the idea of building a shuttle as an airplane that would come in nose-high, then dive through 15,000 feet to pick up flying speed. With its nose so high, the plane would be fully stalled
>Draper preferred to have the Shuttle enter its glide while still supersonic, thus maintaining much better control while continuing to avoid aerodynamic heating.
>The delta also had other advantages as well. Being thick where it joins the fuselage, it would readily offer room for landing gear. Its sharply-swept leading edge meant that a delta would produce less drag than a straight wing near Mach 1. In addition to this, when decelerating through the sound barrier, a delta would shift its center of lift more slowly. The combination of a sudden drag rise near Mach 1, combined with a rapid center-of-lift shift, would [213] produce a sudden and potentially disconcerting change in the stability characteristics of a straight-winged shuttle when slowing through the speed of sound. This change in stability would be much less pronounced with a delta, and would give a pilot more time to react.
>The merits of deltas might have remained a matter for specialists for another important feature of the delta: Compared to the straight wing, it produced considerably more lift at hypersonic speeds. Using this lift, a reentering shuttle could achieve a substantial amount of crossrange.

>>15559706
Absolutely true. I got confused with the catch-a-spy-satellite requirement.

>>15559693
>>15559681
>>15559709

Please fucking read the shuttle decision
>NASA wanted that crossrange for abort scenarios
>Hypersonic flight was badly understood, and Delta was widely seen, in NASA and USAF (although the later did come up with complains earlier) as a safe bet.

Yes early studies had straight wings, yes USAF involvment weighted in, but once they changed NASA NEVER looked back

When the OMB, later in 1971, tried to cut fundings and NASA had to consider falling back to a smaller shuttle which DID NOT fullfill the key USAF requirement (the small shuttle was still to be used alongside Titan III, which would launch stuff like Hexagon satellites)


>With the OMB now pressing NASA to return to the payload capacity recommended by Max Faget, the agency had to consider whether it might cut costs by also returning to Faget’s straight-wing orbiter design
>Charles Donlan, acting director of the Shuttle Program Office, ruled this out. In a memo to Low, he emphasized that high crossrange would be “fundamental to the operation of the orbiter.” It would make the Shuttle maneuverable, greatly broadening the opportunities to abort a mission and perhaps save the lives of astronauts. A high crossrange would also afford frequent opportunities to return to Cape Canaveral in the course of a normal mission, following launch from that site
>Delta wings also promised advantages that were entirely separate from crossrange. A delta orbiter would be stable in flight from hypersonic to subsonic speeds, throughout a wide range of nose-high attitudes. The aerodynamic flow over such an orbiter would be smooth and predictable, . In addition to this, the delta vehicle would experience relatively low temperatures of 600 to 800 O F over its sides and upper surfaces
>Because of this combination of aerodynamic and operational advantages,Donlan favored the delta wing for reasons that were entirely separate from those of the Air Force.

>>15559777
wrong, SpaceX and Tesla have been around like 20 years
the boring company got started like 8 years ago so its too early to tell but the initial portions of the las vegas loop is a success (contrary to what you would read from musk hating news tabloids) and they just finished digging tunnels to two new stations so in fact it seems to be going very well
https://twitter.com/boringcompany/status/1678557789873147905
https://twitter.com/boringcompany/status/1678559122021842944

Neuralink is also very new and it seems to be going forward as human trials should be starting soon
way too early to say they are a failure at this point
XAI just got started
twitter is bigger than it ever was, soon to be cash flow positive so that seems to be going fine too

so all in all, 2 extremely succesful companies basically dominating their own fields, 2 companies that are just about to reach commercialization stage, 1 company that was on the brink of bankruptcy but seems to be fine now (twitter) and one company that was started just now
which one of these is a failure?

>>15559785
zip2 was clearly a success as well, it was sold for 307 million in 1999
x.com was clearly a success too merging with Paypal, which is still around

>>15559848
one company I would argue which was an initial failure was perhaps solar city, which got bought out by Tesla
the solar got basically shut down temporarily and is starting to slowly ramp up now I would say it is not really a success at this point and even if Tesla starts to ramp up solar later, then I'm not sure it can be contributed due to the merging with Solar City
whether shutting it down (well not completely, but operations are very low) was due to the unexpected interest in model 3 and thus needing to focus fully on that or due to the business case just not making sense is still too early to tell I think
I haven't really looked into rooftop solar enough to say what the main problem is, I think labour is one of the largest problems right now

I think cost is the biggest problem. Partially covering your roof with Tesla solar shingles is a cluster fuck. But covering it fully can mean very suboptimal performance for the more shaded side. Traditional panels cost less in purchase and labor to install, and you can easily size the need.
Also grids tend to be chock full of solar energy during peak hours. So the grid operator might not even want to buy your excess production. That means a battery is almost a requirement for your big solar roof to make any sense, driving up cost even further.
It's a luxury purchase for rich fucks. Plebs need not apply yet.

guys when a turbofan compresses air, I understand that a lot of that is to generate more energetic combustion but does the compressed, denser air column allow the blades to generate more thrust against that denser air?

context: will a quadcopter with ducted, stacked, sequentially compressing propellers generate additional thrust considering that no combustion is taking place?

>>15560020
Ducted fans improve efficiency keeping the air on top of the blades from being flung outwards, this only works in Earth atmosphere or thicker cause the efficiency exceeds the extra mass.
What you’re describing is a counter rotation ducted fan

>>15560016
you sure think about cocks a lot

>>15560029
I'm not asking about ducts though I'm asking about compression

is the whole satellite scrap if the reflector thing doesn't deploy?

Have they tested the steel plate yet?

>>15560100
Yeah could be done.
Your main issue would be a battery that lasts that long while solar charging from the faint light of the stars.
Also unknown unknowns we have no way to really test our technology for a half a million year lifetime.

>>15560100
I'm a proponent of this but think we could do it on Europa first.

I once read that being farther outside of the sun's gravity well was better from a military/strategic standpoint. Is this true, and if so does this mean that pluto dwellers will inevitably rule the solar system?

> When you look at the rendering of this new satellite, you’ll notice a few major differences from almost any other communications satellite in geostationary orbit. The most striking is the enormous reflector — one of the largest ever sent into space — tethered to an extremely long boom arm. There are also a total of eight solar panels per wing with an overall wingspan of 144 feet, which is approximately the same as a Boeing 767 airliner.

>The boom arm tethering the reflector is a direct, but larger, derivative of the James Webb Space Telescope’s mission-critical sunshade mid-booms.

>The reflector, key to ViaSat-3’s mission, is exceptionally large for a commercial broadband satellite.

>“I worked with reflector suppliers before coming to Viasat, and I’ve only ever seen one reflector that was larger,” said project engineer Jason Roberts. “This is among the largest reflectors that have been flown. It’s huge!”

I dunno desu. It's more energy-intensive to get to Mercury from Earth than leave the solar system entirely. Dropping things into the interior ain't cheap.

Hey faggots. Remember when you said Gravitics had hardware and Vast didnt?

>commercial space stations
At the moment the only thing they could use to get there is Dragon and it doesn't seem like SpaceX is planning on building more Dragons either.

>>15560249
Which is not the greentext in >>15560206

>>15560283
Vast is the only one using a Falcon to fet its first small module up there. Set for late 2025

>>15560283

CGI can look indistuishable from real images.

>>15560387
It can.

Once the two tanks are connected, the pump starts pumping the liquid-vapor mixture from the receiving tank. The mixture goes through a centrifugal separator, where the liquid is returned to the receiving tank while the vapor is injected into the refueling tank. Higher pressure pushes the liquid-vapor mixture from the refueling tank into the receiving tank.

This method might take a little longer than the spinning method due to mixing in the refueling tank and liquid recirculation in the pump-centrifuge circuit, but it is simpler and subjects the rockets to less stress.

Where is my grant money?

>>15560391
This literally doesn't solve the problem.
You need micro-g acceleration so the vapor and liquid stay separated at the refueling tank.

>>15560338
In Musk we trust

>>15560106
been telling /sfg/ the good word about nautilus for years now. we gonna watch alien buttsex with that shit

>>15560397
Not really. You push the vapor-liquid mixture in the refueling tank with the vapor from the centrifuge, so eventually all liquid will get to the receiving tank and you will only have vapor in the refueling tank.
