Cost of manufacturing it was prohibitive in the early 60s, and Glushko's autistic hatred of it meant they settled with Kerolox and Hypergolics. Not sure where it was mentioned or when, but the Soviets did research Methalox.

>>13889587
Personally he was a brilliant chief designer, perhaps the greatest engine designer there has lived, but he was single-minded in his approach towards space-flight, which exacerbated the competition and infighting within the Soviet Space Program. Fighting with an equally single-minded and stubborn Korolev over the engines for the N1 meant the Soviets diverted resources to the UR-700.
Then, scrapping two N1s when improvements had been made and then spending 10 years on Energia and dealing with the Ustinov's demands for a Shuttle really sapped resources. IMO but the N1 could have become the workhorse in time, and maybe would have evolved into something like Energia. His rejection of hydrogen and then adoption of it after the reorganisation of TsKBEM into NPO Energia smacks not just of hypocrisy but also vindictiveness.

corrosion

The idea of a large pool full of less corrosive liquid would have merit. The only reason we couldn't imagine it back then was because we couldn't / didn't know we could do rockets that land with high precision (not talking of nuclear rocket).

SpaceX would be crazy enough to try, but I'm afraid Elon is too crazy and will want something that look more classy.

If the 50 engine order is for Astra, they'll be fine as long as Astra is, and we'll see Firefly at least make their moon landers and tug. If it's just an IP agreement and a couple engines sent to Astra, and the 50 engine customer is someone else, that looks less certain. The report about Astra buying Reavers seemed to hint at either.
Alpha isn't very good compared to similar rockets by ABL and Relativity, and those have had more commercial success so far. I think Firefly was trying to beat them to orbit (they probably still will) and exude reliability by acing it on their first try (fail). Markusic recently said that they plan for the landers to be a bigger money-maker than Alpha, so they realize that Alpha alone won't cut it. Down the line, Beta seems earlier in its development than Terran R and maybe Neutron, so even if Starship doesn't take too much of the market by then, Beta may be dead on arrival. Integrated moon landers aren't a big enough market to justify these rockets.
They're setting themselves up well as a supplier though, so they may make it there, but they won't thrive.

He said they'd do another engine that would take people to Mars that wouldn't be called Raptor, and he's consistently spoken of dollars per ton to orbit. It's not hard to extrapolate that they're doing a design for reliability+manufacturing engine based on what they've learned making Raptor.

They then realized the full extent of the lies they had been fed, it was no promised land. Nothing would grow in this soil, the cold unbreathable atmosphere would kill them if the radiation didn't. They had no real reason to be here than the fancy of a rich man, and there was nothing they could do about it anymore. They were now stuck here for at least two years, forced to don a cumbersome suit to walk anywhere as their bones grew weak and brittle, they would all desperately work to refuel the few ships that survived, hoping those would last 2 more years in this cold hell. They knew not all of them would live to go back, they all secretly hoped the red hell would take out a few of them so they didn't have to fight for a seat.

After many hardships, . . . the Pilgrim Fathers first set foot upon a bare rock on the bleak coast of Arcadia Planitia, while all around the earth was covered with deep permafrost. . . Dreary, indeed, was the prospect before them. Exposure and privations had prostrated one half of the men before the first blow of the ax had been struck to build a habitation. . . . One by one perished. On the first of that month, forty-six of the one hundred emigrants were in their graves.

>>13890212
Also Elon's got people working on a successor to the Raptor engines. So he probably means by the time it takes all the space companies to get their act together to get colony-level supplies to Mars, they'll be taking off on that new engine.
Also, that new engine will probably only be taking off. To get to Mars from High Earth Orbit, we'll likely be using a NERVA engine. UltraSafe is working that beat, not SpaceX.

That's dumb, a rocket with NERVA engines would have no real advantage over Starship once accounting for the mass penalty from using hydrogen and you would still need multiple Starship(or SLS as this is another pork project) to assemble the rocket in orbit as no one is going to allow NTR launches from Earth, in addition you need another lander for Mars if it cannot aerobrake so more delta-v is required. Look at all the garbage NASA NTR concepts for proof.

There was no mention of not going to Mars. If anything, there's a vague notion of "engine that can (((actually))) make life multiplanetary", the !Raptor.

The notion that Raptors wont bring humans to Mars is not implied, what is implied is the possibility that (actual) aka full scaled multi planetary colonization would require a new engine.

The issue is more the specific energy of the battery rather than just the extra mass of the motor and the metric to be concerned about is cost and reliability, not performance. Raptors are good and reasonably cheap but they're not the best choice when you're 200 million km from Earth.

I think the Raptor 3 is separate from the new engine which would have a different name and perhaps cycle. I just don't know what it could be or the purpose of switching over to it for the Mars version of Starship. If the gain was in performance it wouldn't make much sense for them to still produce Raptors, this implies that the advantage is in safety or cost, what other reasons are there?

What other cycle would it make sense to use?
Lox/Methane rich single pump requires a seal and doesn’t offer any better performance.
The only cycle that could be competitive in performance and offers greater reliability is the expander cycle. But it has the problem that total power is limited by the square/cube relation between nozzle area and volume. They would have to use multiple nozzles or a linear aero spike.

I have no idea about what could improve safety that also requires a total redesign.
I had not considered cost but I also can’t think of one or few components that would significantly decrease it. Maybe there is a better alloy than inconel? That would be a change dramatic enough to require new cooling and plumbing.

Maybe it’s a bunch of small bad decisions that compounded and lead them to a dead end.

Doesn't have the requisite specific heat capacity. They are using slush hydrogen to cool incoming air, compressing it and burning it in 'air breathing' rocket engines. To compress the air enough to do this you have to cool it and that requires a hella lot of cooling capacity. Slush hydrogen is pretty much the only thing they can use.

Not the most practical design, could be so much easier to just use a fly back booster. Personally I would like to see a turbojet/ramjet stage 0 on a "single" stage to orbit spaceplane.

Mars is half argon / half nitrogen excepting the CO2, so presumably... half Ar / half N2 at the poles where the CO2 freezes.
So the colonists will be breathing Ar / N2 mix with 21% O2.
The problem will come where they need nitrogen for crops.

>>13890894
>Electric but there's no fucking way the battery mass is worth it
That’s why I suggested electric expander cycle.
Expander is highly efficient and simple but takes too long to start. Electric is fast to start but running for long periods of time is wasteful.
Of course you could start an expander cycle with compressed gas too...
And you still would need multiple nozzles... raptor currently delivers 1.8MN so to use an expander cycle and achieve roughly the same you would need 5 or 6 nozzles at the 330kN limit each. (Wikipedia says that is the limit)
SH does have area to spare underneath it, starship not so much.
>>
>>13890894
>there's also Electric but there's no fucking way the battery mass is worth it
I wouldn't be so sure, iirc someone on NSF ran the numbers on the Falcon 9 using scaled up Rutherford engines and the mass penalty was quite reasonable. I haven't seen anyone do it for Starship and it might not be a good idea right now with current battery technology but ten years from now it could be a different story. Clearly this new engine is a long term ambition and as far as I know they're still moving ahead with the factory near Boca Chica that will produce Raptor 2.0

They're going to be condensing nitrogen out of the atmosphere for their fuel production. Haber-Bosch is energetically pricey, but could be done using chemical feedstock that will already be lying around. You could skip the Haber-Bosch for food production by inoculating the soil with nitrogen-fixing bacteria. Long term colonization efforts would probably benefit from having industrial ammonia production though.

To be fair Merlin is open cycle, Rutherford is “closed cycle”, this could make it up for the battery mass. But starship is already closed cycle.

I'd like to see a electric-pump-fed 3rd stage for Starship, just designed for the last portion of reaching space, landing on Mars, and returning to LEO as let's face it not a lot of cargo is going to be coming back from Mars anytime soon and humans should reenter on a fresh ship. The same design could eventually be used for Lunar Starship, just without the tiles or used a kickstage for small payloads not worth orbital refueling.

Why not? There is not a great mass penalty if you don't have to do long high throost burns. This is from another post about scaling Rutherford.

>Wanted to see how well an electric pumped Starship kickstage would work with refueling. If a kickstage was carried up empty, but ready to be fueled with and then burn 80t of methalox in an engine with the same burn rate as Rutherford vacuum but on methalox...
>80t of methalox at 7kg/s takes 3.17 hours, and 317 kW/h of electricity to run a 100kW pump.
>1268kg of battery mass at battery capacity of 250 Wh/kg for Li-Po. A surprisingly small dry mass penalty compared to tank mass for 80t propellant. Also assuming that batteries could fare quite well with a discharge rate not much more than 0.3C
>If that battery and the rest of the stage can fit inside 10t empty mass, then it can consume less than 10% of Starship's payload, and still deliver useful dV to the rest of that payload after refueling. (Had been thinking of Lithium Sulfur, but I can't figure out if Sion's version of those is real or cancelled... But they would do well enough at ~0.3C discharge.) I don't at all know if a Rutherford vac could be modified to handle 3h runtime on methalox, with the same propellant flow rate it has now... Or if that would be worthwhile to build. Amusingly the Falcon 9 second stage is something like 3X lighter than my guess in mass fraction, and gets better ISP than Rutherford vacuum... but couldn't be refueled from Starship's main tanks, so it might have lower payload capacities to lower dV's.

The argies attacked the HMS Invincible with two bombs and the last exocet.
A pair of super etendarts launched the missile and headed back. The other Skyhawks continued in the direction of the missile. When they arrived the carrier was smoking.
2 of the four skyhawks were shot down and the other ones missed.

The carrier was most likely damaged, that is why she returned after the fleet.
>>
>>13890984
Ah. On Wikipedia, I see the Bongs maintain that the Invincible was never struck, and her destroyer escorts were able to down the exocet. Most of the media I've seen on the Falklands has been British which is probably why I've never seen this.

While we're Falklands posting, heres an interesting fact about the Argentine invasion of South Georgia, codenamed Operation Alpha
>On the face of it, Operation Alpha was a perfectly workable plan. It was basically a Southern Thule-style military escapade, and there was no reason to expect drastic consequences. The problem, however, was that it muddied the waters for the plan to invade the Falklands, which was an entirely separate undertaking. Indeed, some of Admiral Anaya’s senior commanders thought they had persuaded him to postpone Operation Alpha and were horrified to hear it had gone ahead. There was obviously no chance now of an early breakthrough in the negotiations, because the British were furious. Worse, with Britain’s attention now focused on the South Atlantic, Anaya’s commanders were in danger of losing any element of surprise. The irony is that if Anaya had shut down the stunt in South Georgia he could have launched the conquest of the Falklands a few weeks later, when the weather would have made a successful British expedition almost impossible. But as it was, the British reaction forced him to bring the invasion plans forward. And although she could hardly have known it, this was Mrs Thatcher’s great stroke of luck.
tldr; if the Argentine military had all been on the same page they would have had a good chance of prevailing

Because expander cycle is much more efficient. Rutherford is a good option at seal level when you need a lot of thrust and can’t use expander because it’s limited by the area/volume relationship of the nozzle. Or when you want a simpler engine.
Vacuum engines that use something other than expander usually do so for simplicity. If you are designing an engine from scratch to work in space alone then expander is the way to go.

Im still fond of the idea of having a electric start for a multi nozzle expander.

i think most people are onboard with the idea that russia will invade ukraine by february. and since the west so far has been willing to back ukraine in various ways, we could see something happen in space between russia and the west. for example, we could see russia try and damage or destroy an american spy sat. we've already had them willing to engage in harassing behavior like that before

>Kosmos-2542 passed within 20 km of USA 245 several times on Jan 22. The closest approach was about 13 km. Kosmos-2543 is making regular distant passes of USA 245 about every 4 days, to about 100 to 200 km.
>It seems unlikely that this is coincidental, although I am open to counterarguments. It would appear that both Kosmos-2542 and 2543 (which were launched together) may be observing the US spy satellite, which was launched in 2013.

The erasure of religious ritual and identity does not result in the end of religious fervor. Whatever it is you've substituted for god may not be the God of the bible, but your god is something, and I'm willing to wager that whatever it is you've made into your own personal god isn't telling you to go forth and prosper. You think you hate religion. In reality you hate stupidity, fanaticism, and corruption. "Smart people" are immune to none of those things.

Excerpted from Von Braun's Project Mars (the book where the Elon is the ruler of Mars)
>"Life below ground, to which our aging planet has condemned us," said he, "has made us forget that another and a greater world lies without the hermetic capsule wherein we perforce must live.
>"Until our Earthling friends and brethren came to us through the airless reaches of the solar system, we were in danger of entirely forgetting that there is a heaven wherein God guides the courses of the stars of His creation. We awoke to the joyous discovery that we are not alone in the infinite ocean of the stars. We rejoice that our kindred from across space think, feel, hope and believe as we do.
>For eons we have sought the answer to the final question, the great, hitherto insoluble question of the purpose of the cosmic creation - why did God make the magnificent machinery of the universe? To this day, our natural scientists have stood perplexed but gripped in the fascination of its endless complexities and bemused by the infinity of its riddles. Our Earthling companions have brought us the answer: it is Life! Joyful, pulsating Life, everlastingly sustained by the two divine urges, Love and Hunger!
(1/2)
>>
>We may well still wish to know what is the purpose of this life, and to that question, too, they have brought us an answer full and complete: it is the quest of perfection! In this quest, life has evolved from the amoeba to the thinking, sentiment being, following the dictates of the conscience with which God in His own good time endowed it, so that it might seek Him and strive for His perfection in the full knowledge that never can it fully be attained.
>The inspiration of your cosmos-shaking journey, my Earthling brothers, cannot have been that of a purely technical experiment, despite the magnificence of its conception. You have come to us on a mission whose ultimate object was planned by God Himself, for it is you who have brought together the germ plasms of rational creation in our solar system that they may thrive and grow into a higher and more noble organism, which shall envelope the depths of space. In no other manner than by the joining of individual cells did the higher forms of life evolve at the beginnings of time!
>Let no man here, whether Earthling or Martian," cried Ansanto prophetically, "misapprehend the significance of this mission! Let us follow in the path it so clearly defines for us, and may the generations which shall come after us never deviate! Then, and then only, may we be assured that we have seen God's plans and aims, and that we follow His Holy Will towards His cosmic ends."

"Atheism is a religion" is such a dumb take. It's like claiming zero and the empty set are the same thing. It's a very similar error to people not understanding how "latest common ancestral mitochondrial DNA to all of mankind" doesn't mean that Eden is a true story because they don't understand how tree data structures work.

I wonder if among the countless carbon-based civilizations out there, if there are any at all of course, and considering this type of life in general not that different from that of E*rth, the majority of them would be more similar to reptiles rather than mammals or any furred creature.
>>
>>13891587
IT might be that a bipedal body really is universally useful, and a head (sensory organs near the brain) with a mouth attached is just efficient. Alien life might be surprisingly similar to us.
>>
>>13891590
It's also possible that bipedal dinosaurs could have reached such a shape given enough time. Scales are simpler to evolve than hair/fur systems, so I suspect if a planet had fewer catastrophic comet strikes than Earth did, scaled bipeds might reach orbit.
>>
>>13891590
Oh yeah, I agree. When I said reptiles I meant bipedal ones, like those reptilians in conspiracy theories lol.
Also, it would be interesting to know how an aquatic intelligent species from an ocean planet, if they were to somehow evolve into a humanoid shape, would fare when trying to get out of their planet. They'd have it harder than us I think.

I suggest reading about evolutionary pressures and just evolutionary biology in general. Maybe it would change how you think about extinction events, since they function more as an opportunity and occupied niche+ecosystem reset switch rather than a setback. There is a reason, after all, for why European honeybees as a collective and individually are the most intelligent arthropods on the planet.

>Parker Solar Probe will break its own distance and speed records on that approach – the 10th of 24 planned, progressively closer trips around the Sun – when it comes about 5.3 million miles (8.5 million kilometers) from the Sun’s surface, while reaching top speeds of 101 miles (163 kilometers) per second, or 364,621 miles per hour.

Ummm, that's not how it works.

Once a year, Curiosity would stop and celebrate the anniversary of its arrival on Mars by stopping briefly to sing "Happy Birthday" to itself. Then, once again, it continues through the dry desolation of the planet surface on a path of discovery. When you stop and look past all the scholarly debate and man-made traditions of Christianity and look at the basic message of love and salvation presented in the scriptures, you will discover a beautiful picture. Over time, the simplicity and accessibility of this message has been diluted and overcomplicated.

I disagree, we're not particularly angry, there's just not much going on right now.

>The primary difference between the Falcon 5 and the Falcon 1, as the vehicle unveiled Thursday is now called, is in the first stage. Instead of using a single “Merlin” engine in its first stage, as the Falcon 1 does, the Falcon 5 will cluster five such engines in a longer, wider stage. The second stage of the Falcon 5 will be similar to the Falcon 1, and the Falcon 5 will sport a larger payload fairing, three meters in diameter. Like the Falcon 1, the Falcon 5’s first stage is designed to be recoverable, and hopefully reusable.
>That larger first stage will give the Falcon 5 a much larger payload capability than the Falcon 1. A SpaceX document listed the capacity of the Falcon 5 at nearly 4,200 kilograms to low Earth orbit (LEO) and nearly 1,250 kg to geostationary transfer orbit (GTO).
>Musk pointed out two key characteristics of the rocket. “Falcon 5 will be the first US launch vehicle with true engine-out capability in over three decades, since the Saturn 5,” he said. That engine-out capability means that an engine can fail during flight without preventing the success of the mission. “We can have multiple engines fail, depending on the phase of flight, and still have a successful mission,” he said. He later said that up to three engines could fail, again depending on what part of the flight the vehicle is in. “We think that will really have a dramatic improvement in the reliability of access to space.”
>The other noteworthy feature of the Falcon is its price: SpaceX plans to sell the vehicle for $12 million a flight: about $2,850 per kg, or $1,300 per pound. “It’s going to set a new world record for the cost per pound for access to space,” he said. “That’s a huge improvement over anything else.” Musk said the Falcon 5 should be available for launch in 2005. “We’re discussing first launch with a number of potential customers right now,” he said, but did not elaborate on whose those customers might be.

maybe at some point a change in engine configuration meant that they'd have to flare the skirt out and mounting legs to that was going to be way more complicated?

My theory is life is common but intelligence is very rare. We know that star systems regularly pass by earth(Scholz’s star passed within Sol’s Oort cloud 70,000 years ago, and was going fast so it’s currently 22 light years away; it’s estimated stars go through the Oort Cloud about every 100,000 years). There’s a cloud of spores, bacteria, algae, etc that’s been blasted off earth from big impacts like the Dino killer asteroid. Those specks of life have some tiny bit nonzero chance of getting deposited on planets that come near earth. Most of the seeding will just be comparatively low complexity life (single celled), but even a single algae cell could terraform a world and be the foundation of a new tree of life. Although that panspermia’d planet would have a common ancestor to earth, the very early stage of the seeding event means the complex life that’d develop on those worlds could be very different. They might have intelligent octopusses instead of primates.

I think martians will have way higher than 2.0 fertility rate. I think Martian society will incentivize smart, motivated women to have tons of kids by structuring society to make it so. In the rich earth countries now, women must choose to have a career or have kids in their late 20’s/early 30’s. I.e a female doctor waits to have kids til after residency. This means the window to have kids is short so fewer kids are had. These smart, motivated women are precisely the kind of citizens Mars would want to propagate to grow a smart, motivated native population. So how do they make it happen?

They make public schools excellent (the opposite of most places), and make houses large so the marginal cost of additional children on families is low (literally the opposite of Singapore).

They reduce credentialism significantly (I think most jobs could be done by smart highschoolers, and it’s a damn shame to make people waste their most fertile years learning stuff that in almost all cases is worthless).
They make society high trust (like japan where 2 year olds can be trusted to run simple errands “Hajimete no Otsukai”, and society at large looks out for all their children’s welfare. Anyone harming children gets to go for a walkabout on the surface with no spacesuit).

It also follows that planetary protection is immensely stupid— planetary protection had assumed the only way for life to spread was in artificial satellites but evidence shows Mars <-> Earth panspermia is possible (and even likely!?) with purely natural means. But now we can update our prior opinions on even Interstellar panspermia as more likely because we know that stars pass close to earth so frequently. If life on earth is 3.7 billion years old and stars pass nearby every 100,000 years there have been 37,000 stars potentially seeded! Many stars have several planets in the habitable zone (and beyond that, life could live someone outside the habitable zone if there was latent heat or generated heat from tidal forces or fission) so the possibility of panspermia must be considered

My theory on the great filter is that communal intelligence is rare. If humans were solitary but smart we couldn’t individually ever build anything complex. If we are social and dumb we couldn’t build anything complex. The combination of smart, social, AND able to avoid other self interested people keeping us planetbound make us an extreme outlier.

planetary protection seems like the old division of the cosmos being divided by the sublunary
sphere dressed up in postmodern leftist garb
>Medieval scholastics like Thomas Aquinas, who charted the division between celestial and sublunary spheres in his work Summa Theologica, also drew on Cicero and Lucan for an awareness of the great frontier between Nature and Sky, sublunary and aetheric spheres.[6] The result for medieval/Renaissance mentalities was a pervasive awareness of the existence, at the Moon, of what C.S. Lewis called 'this "great divide"...from aether to air, from 'heaven' to 'nature', from the realm of gods (or angels) to that of daemons, from the realm of necessity to that of contingence, from the incorruptible to the corruptible"

>General Power was not out there alone. He had the full support of the Chief of Staff of the Air Force, General Curtis E. LeMay. Writing in a 1962 letter to Power, he said, “I share your views regarding the potential of ORION.” Nor was it just talk: both the SAC commander and the US Air Force Chief of Staff were willing to put their money where their mouth was. In 1962, funding for the SEOB and Orion propulsion development together accounted for $1.36 billion (over $10 billion in 2014 dollars), or 18 percent of the total Air Force space development budget for fiscal years 1963–1967, as requested by LeMay in his Air Force Space Program.

I'm not going to argue against the worth of the war. Wars are to be won, that's an indisputable fact. But what does incinerating entire cities full of innocent people gain towards winning? Judging by our experiences in WW2, it does nothing to end the war any quicker.

WW2 was bad because that Fabian prick FDR and his admin full of communist spies and fellow travellers helped destroy what remained of the West after WW1 by throwing their full weight behind Stalin. His successor had the right idea
>Harry Truman, a rising star in the Democratic Party, proposed on the Senate floor on June 23, 1941, that US policy should be conditional on the progress of the fighting: “If we see that Germany is winning we ought to help Russia and if Russia is winning we ought to help Germany.”

sure. nuremburg was a mockery of justice by any conception. the legacy of putting defeated enemies up for show trials on charges for crimes against an international law that the victors made up on the spot instead of just hanging them is one of the worst things america's ever done.
>But what does incinerating entire cities full of innocent people gain towards winning?
because we thought were going to have to invade japan and wiping out industrial production in tokyo was a key step in softening them up? it wasn't america's job to build bomb shelters in tokyo, that was japan's, and they decided that they had better uses for the concrete.

Yes, particularly the offshore launch platforms. He might be able to get starbase to 10-20 launches a year though, which while not a lot, is probably more then enough for the current commercial market.
