Oh I dont know, maybe catching on fire, blowing up for no reason (SpaceX still doesn't know why). How bout 3 not turning on at all? any more than that and it's mission failure.

[Anonymous No.15434798]

>>15434768
One interesting thing about R3s is that at the TWR goes up, they can drop the number of engines on the booster, reducing the overall failure risk.

230T x 33 = 7,590T thrust.

269 x 33 = 8,877T thrust.

This means that they can drop the total engines down to 28 and reach 7,532T of thrust. We know for a fact that Starship OFT never reached 100% thrust and was at 90% the entire flight until TVC was lost and it still got up to 39km. So 90% of 7590T = 6,831T.

Based on all known data, if not for 11 engine failures and TVC loss, with 90% thrust, there's a good chance it would have reached orbit. For safety margin, let's assume that you need 7000T even to get to orbit. That then means that with R3s, you can drop the engine count down to 26 and you get 6,994T. Which is 163T more than 90% of R2s 33 engine thrust profile.

7 less engines with R3s on a booster and you can still get to orbit. Theoretically speaking. That means that for every 4 boosters you then build, you'd get 1 booster worth of engines "for free" if compared to the R2s configuration for Super Heavy boosters.

That's INSANELY GOOD outcomes.

>>15434806

Yeah, but I think SpaceX may go the option I suggested, so that they can launch more ships simultaneously rather than launch the same ship more times. Because flight time is still time where no additional payload is being launched. Since Elon grades rockets by useful mass to orbit, for every 400T you get 100T to LEO "free" is thereby better than waiting for the time to get the booster back and fly again. Imo.

Also, for additional reference, the SLS’ thrust to tons at launch is 4400T. So 26 engine R3s at 90% thrust gets you 1.589x more thrust than SLS. Truly absurd.

[Anonymous No.15434816]

>>15434807
They chickened out in 2018 relative to the 2016 spec.
>>15434814
They'll keep the engine count high and stretch the first stage's propellant tanks first, I reckon. With that much more thrust, they'll probably be able to push the reusable payload to 200 tons to orbit, which would cut the number of tanker flights to completely refuel a Starship from 8 to 6.

Raptor 2 increased its thrust by around 24% with a 20% increase in chamber pressure, which was achieved by widening the throat and lowered the specific impulse by 3s as a result. Raptor 3 has very roughly equal increases in chamber pressure and thrust over Raptor 2 at about 17% each, so the specific impulse should probably be the same... maybe better?

> Starship Raptor V1 vs. Raptor V2 = More power, less parts.

>SpaceX is working to rapidly improve the Starship launch vehicle and make manufacturing cost-effective. The company has been able to achieve this with the rocket engines' development.

>Raptors are fueled by 'Methalox', a combination of cryogenic liquid methane and liquid oxygen which is a unique fuel in the rocket industry. V2 is the second iteration of the engine, it has less visible plumbing/wiring & is more powerful. Both sea-level versions have the same nozzle exit diameter and similar dimensions, however, V2 is lighter than V1. Raptor V1 has a mass of 2,000 kilograms (kg) and V2 1,600 kg.

>V1 generated around 185 tons of thrust and the current V2 generates ~230 tons of thrust, making it one of the world's most powerful rocket engines.

>V2 production cost is around half of V1. SpaceX aims for the cost-per-tonne of thrust of each Raptor to be under $1,000 — so around $250,000 to produce.

didnt remember that there was such a large drop in mass, thats pretty crazy
so the thrust from v1->v2->v3 goes like
185->230->269 (tons)

More like the RS-25 was retardely overcomplicated and overengineered while the RD-0120 was much more simple in comparison.

Though the chart is a bit misleading seeing as the RS-25 has a little bit more thrust than RD-0120. It's a slightly better engine in terms of performance overall.

https://arstechnica.com/science/2023/05/the-ariane-6-rockets-debut-will-slip-into-2024-the-question-is-how-far/

> So in the best-case scenario, it seems likely that the European Space Agency and the rocket's developer, ArianeGroup, could complete these milestones by the end of the third quarter of this year. Assuming there is still a nine-month period between their completion and the inaugural flight of the Ariane 6, we can set a "no earlier than" launch date for the rocket in the second quarter of 2024. More realistically, the launch will occur sometime next summer.

> There has been some criticism that Europe did not innovate enough with the design of its Ariane 6 rocket when the vehicle was conceived in 2014. The booster is largely an update of Ariane 5 technologies, with an eye toward reducing costs, rather than a major step toward a reusable booster like the Falcon 9. However, if the rocket had arrived by its original target in 2020, it would find no shortage of customers given the current lack of launch capacity in the Western world.

> Instead, the Ariane 6 will now be about four years late and compete against a new generation of rockets with varying levels of reuse and cost competitiveness—including Rocket Lab's Neutron vehicle, United Launch Alliance's Vulcan, SpaceX's Starship, Blue Origin's New Glenn, Relativity Space's Terran R, Japan's H3 rocket, and more. In other words, had ArianeGroup executed on the development of Ariane 6, it could have gotten the jump on all of these vehicles and been the West's alternative to the Falcon 9.

so I guess the rumours from one of the tank providers was right, specifically

I have a question about the fermi paradox and SETI:
how far away are we actually capable of looking? Say for example there was a civilization that was an exact copy of earth, down to our radio signals and everything, but as many years in the future as it is light years away (ie. if it's 40 light years away, it's 40 years ahead of earth, so their radio signals look exactly like the ones we are sending out in 2023). How far away could we spot them?
Also if they weren't emitting radio or any other signals, say the planet only had plants and microbes and what not, would we even be able to spot them in alpha centauri?

Without more information I'm inclined to believe that unless someone is building a ton of dyson spheres very quickly right next to us we wouldn't be able to spot them and the answer to the fermi paradox is "we don't know because we haven't actually done a good job looking"

No, engineering applies scientific results when useful but does not require any particular stance on truth.

That's a big asterisk. With CH 4 nuclear thermal you get only 625s Isp at 3000K vs ~900s with LH2 but your tanks are like 1/6th the volume and it is much easier to store. Neither is worth considering until you're operating at much higher temps and the fuel is no longer solid, even then you're so limited by cost it's not a solution for any type interplanetary colonization effort.

So added complexity that doesn't address the fundamental problem of spaceflight, which of course is cost. Let me create for you a short list of realistic near future spacecraft:

>Power sails feeding EP ships with much faster acceleration vs. conventional designs
>Mag sails, possibly with artificial magnetospheres installed near planets without one
>Laser electric and laser thermal, both have high upfront costs but very low marginal costs, an interplanetary highway can be achieved. This is near end game technology unless antimatter becomes readily available, can do interstellar missions that span only a couple decades instead of a human lifetime or more
>Sundiver style photon sails for deepspace flyby missions and out to the solar gravitational lens point
>QI thrusters(joking)
>Slowboating with chemical and depots all over the place, autonomous ISRU and resupply

How do you do such a bad and slow job of copying something when all the corporate espionage has been done for you in immense detail by an army of autists that you didn't even have to pay.
By the standards of this level of industry, BO essentially has an IKEA manual for how to build a gimpy Starship clone with BE-4s, and this is what they have so far. When was Jarvis first heard of, again?

It's poop. Zubrin only proposed it as an air breather for Mars (or Venus I guess) because external propellant has an Isp of infinity as long as your reactor doesn't break.

Remember Spaceguy5? The s o y boy NASA employee that works on SLS, constantly talks shit about SpaceX, claims that the number of refills for Starship HLS is at least 14 and that they did destructive testing with people still near the pad?

This is the most bland, unspirited, limp-brained description of that situation considering his personal connection to it.
Not that I'd never discuss that sort of thing on any account associated with my actual identity in the first place, but it reads like he ran this by a panel of sensitivity readers and a lawyer before posting it.

That's incredibly fucked. Kennedy v. Louisiana was a mistake. There's something very unnerving about this guy's posts though. He doesn't seem to have any real emotional attachment to the issue. Could just be a coping mechanism but it seems like the epitome of an npc response. It's like he heard the story from a friend or saw a post on the internet about it. Also annoys me that he's posting about the kids' personal shit, and on an account which could be linked back to them.

Either coping mechanism or a sign of derangement. He's the guy who wants to fuck horses. His ex divorced him. Then married another guy. She later killed herself. Then the step father that she married was also a creep pedo. Horsefuckers and pedophilia are of the same kind given the show was aimed at children and these grown men are likely attracted to children/s horse shows as a romantic partner in life because of their innate pedophilia to begin with.

Thats on top of the hatred/seething of everything Musk/SpaceX from the guy. He probably sees Musk as a successful man, with many children, and career that surpasses his own, while not being a pedophile. So he sees Musk as a threat.
