to

Is there anyone not deranged or delusional in this space?

>>16199837
wow, that's a lot of dead mexicans.

>>16199871
Because it's a challenge. Level 1 is getting mars habitable. It has a similar day length and enough water on it that it can be easily freed. Venus is 100x harder because you have to make the planet spin faster and find a way to get rid of all the excess gas. Also look how ugly it is

What are the chances that plate tectonics are really unique? Like, the only reason Earth has plate tectonics is because of the collision with Rhea?

>>16199871
I don’t think it’s unrealistic to think that humans could unironically colonize other star systems given enough time. And Mars / Venus are good candidates for us to learn how to craft similar Earth-like planets to our will. That knowledge will go elsewhere, to other star systems, potentially.

If the solution to the Fermi paradox is that all the aliens are too limp-wristed to conquer the universe, I say that's a good thing. More planets for us.

Good OP, nice job

>>16199889
It's very likely that they are extremely rare judging by our solar system. There is no other body in the solar system with active plate tectonics. One of the thousands of things which make the rare Earth hypotheis very likely. I think the videogame 'Space Engine' gets it right. Most 'inhabited' planets are not great and have a small amount of life clinging to them with an extremely slow metabolism, which are always micro organisms less complex than Earth micro organisms. Kind of like Mars actually.

Why do stars in this universe have to be such piss poorly designed? F/G/K stars before they hit the wall are likely the most comfy for life. I could not be assed to live around a dimly lit M-dwarf system.

>>16199891
Regardless of how much it may be in the range of impossibility or outright fantasy, I firmly believe that it is within humanity's right to rehabilitate the other worlds in this system, and grant the sun a new lease on life however possible. Earth, its moon, and the bright white sun (when not too luminous) is holy beauty and perfection. Yet it is all so incredibly fragile.

>I spy a pair of BE4 engines about to go onto their booster for USSF106, VulcanRocket‘s first National Security mission.

If these are for Vulcan's first NatSec launch, then shouldn't the pair for its second certification flight already be there? Are engines actually piling up while ULA waits on payloads?

>>16200072
my uncle works for astronomy and he confirmed the pixels are real

>>16200074
there's a picture of another vulcan with engines on it isn't there? I thought I saw it on here

An LH2 based Solar Moth gets an Isp of about 900s. This means a water prop Solar Moth should get an Isp of at least 300s based on ratios from NTP studies, probably more since the "fuel element" is sunlight concentrated into a zirconium oxide or diamond focus that doesn't mind exposure to steam plasma.

Consulting basic delta V maps, a rocket with an Isp of 300s and no boiloff risk could do a fully propulsive transfer LEO to LVO with a mass ratio of about 5.5, super doable with water tankage, and less with aerocapture/braking like Magellan did.

This means if we can shrink the solar moth system down far enough to be 4 tons launch mass including payload, a whole Venus mission could be launched on a Transporter mission. At Starship prices ~$100/kg that's crowdfundable.

>>16200078
Turns out the engines for V002 are already on their booster

>>16200086
there's no way that designing and building the first solar moth ever from the ground up would be cheaper than buying one of tom mueller's tugs which would do the same job better

>>16200091
it would be significantly less gay

>>16200087
I think the only thing really terrible about it will have been how long it took to get it into mass production. It doesn't hit Raptor's absurd performance benchmarks, but as a domestic RD-180 replacement it doesn't look like it's disappointing anyone. Right now they're getting enough hardware for a monthly Vulcan launch with the rate still increasing. This is a big improvement from the Delta IV/Atlas V status quo.

All that ultra-expensive hardware that requires so much care, it is a scientifist theatralisation. You should have realised this just by observing things like the countdown ritual. You know something is off. The goal of this expensive show is to delude people into the fake worship of technology, and to lure them into the defense industry, which is what lies behind civilian aerospace.

This really isn't ahead of anything. Ceres-1S lifts 300kg to a 500km sun-synchronous orbit. That's about the same as India's SSLV or 150% of what Electron could manage. It's just that this small rocket launched right next to a large city in China so it had a larger in-person audience than Apollo 11.

Shut up

>>16200462
hmmmmmmmmm

>>16200435
its too long for a single screenshot, basically an article

"As a founder of a launch company, I disagreed with the thrust of this NYT article. I admire SpaceX and welcome their success.

Our goal at ABL is to create fundamentally better launch systems, spread them all over the world, and launch all kinds of new technology that is 10x – 100x better than what exists today. We can help guarantee security, explore our solar system, study the cosmos, and improve billions of lives in the process.

The only way to do this seriously is to push the cost of launch as close as possible to it’s physical limit. Everyone working on launch systems is on the same team in this goal. SpaceX continues to raise the bar as high as they can. We don’t feel short-changed by it, we feel challenged and motivated to do the same.

Addressing a few specific points in the article:

Is rideshare pricing anticompetitive?
Some rideshare missions have definitely launched at a loss. Just do the math. Others have launched at a profit (particularly those with “cake toppers”). On average, with all costs baked in, it’s probably somewhere between a slight loser and slightly profitable. Which side of the line it’s on doesn’t really matter. Whether you are losing $4MM or making $6MM per rideshare launch, there’s no doubt it’s the least profitable activity.

And yes, it’s (partially) motivated by putting pressure on new entrants. That’s not too hard to corroborate if you speak to the right people and they are honest with you.

but…

at the end of the day this program has been a MASSIVE boon to our industry. Almost every innovative space program I can think of depends on rideshare to get started, test technology, get heritage, and build further. The existence of this program has increased the total demand for launch over the next 10 years by a multiplicative amount."

>>16200472
Elon's reply:
"Thank you for the thoughtful rebuttal.

To the best of my knowledge, none of the rideshare missions have lost money.

I do hope that rocket companies focus on reusability. That is the fundamental breakthrough needed for humanity to become a spacefaring civilization. Falcon is ~80% reusable and the team is doing incredible work launching every 2 or 3 days.

With extreme effort, Starship will eventually take reusability to ~100%. There are many tough issues to solve with this vehicle, but the biggest remaining problem is making a reusable orbital return heat shield, which has never been done before. The Shuttle’s heat shield required over 6 months of refurbishment by a large team, so was not reusable by any reasonable definition of the word.

This will take a few kicks at the can to solve and requires building an entirely new supply chain for low-cost, high-volume and yet high-reliability heat shield tiles, but it can be done."

kek you retard

>>16200477
I use chatgpt and/or copy reddit comments here

>>16200296
Maybe use larger tiles with more hold-points? It only takes 3 pins to break to lose a single tile, if it was 9 or 12 I feel larger tiles would have more chances of hanging on.

space is easy
reuse is hard

>>16200502
seems like an issue with the pins and the hold points and not with the amount of pins and hold points. the larger tile size idea is a good one, but the weight on itself (especially in atmosphere) will be not very good for it. mabey use the spray on shoes flint lockwood used in the first cloudy with a chance of meatballs movie, not joking an easily applied expanding material which firms quickly and sets hard could be a good solution, ditching the entire idea of a tiled surface.

>>16200647
It was always ice in the tanks. Keep up.

IFT1 using V1 engines had multiple fires in the engine bay wheich destroyed loads of engines because the heat exchangers leaked fuel into the engine plumes, V2 solved that by deleting the heat exchanger and pumping preburner gas directly into the tanks as pressurant. But the preburner gas contains water which forms ice and blocks the engine inlets. That's why following IFT2 and 3 they have increased the beefiness of the filtration system. We will see if it's enough.

>>16200649
The engines actually died because blockages, sloshing had nothing to do with it.

>>16200720
Yes, next week.
The 5th of june, which is on the week after the week which contains the 30th of may.
That week. Right.

People talk about the difficulty of doing higher energy re-entry, like mars return, but Starship can maneuver to some degree, unlike a capsule.

You could for example re-enter at higher altitudes with lower peak heat and use the starship's lift to keep you in the atmosphere for longer.
You could maybe also do a multiple pass re-entry.

I don't understand rarified gas hypersonic thermal and fluid dynamics, but it works in KSP, so surely it should work in real life.

>>16200724

>Ceres1
More interesting than the last two, but it's just a mostly solid rocket design which is carrying "two new satellites" (more detail not provided, but presumably EO sats). They should have moved on from this rocket by now.

>>16200888
Thanks for giving me a quick rundown on SpaceX history. Elon Musk shook hands with many presidents

Musk having some very close advisory role where he can influence FAA and other stuff would be quite significant
it wasn't off topic, it was directly related to regulation

>>16200882
Obamna was on a crusade to deflate NASAs budget so handing off ISS resupply to a private company fit that narrative. Constellation was cancelled and he wanted to cancel human spaceflight indefinitely. It was a happy confluence of interests where Obamna trying to gut NASA gave room for SpaceX to emerge, and then Trump brought back constellation in the form of Fartemis giving them room to go interplanetary without eating the entire cost. We are in a brilliant timeline really. If Trump wins the next election and has Musk in his inner circle then Moon by the end of his term is possible.

>>16200822

wouldn't that be illegal

would trump have enough influence/power to cancel artemis? or at least extend it so the earth->moon orbit portion could be done with private launchers and wouldn't need SLS

>>16200906
>where do you think all the other post-Singularity civilizations went?
They created an AI which destroyed the civilization and then destroyed itself.

>>16200900
then don't go, its as simple as that

>>16200909
they aren't close yet, this is just some preliminary talks
I don't see how that would be illegal, just make the regulations less retarded, cut AST out of FAA and give them a bigger budget so they can keep up with the licenses (or change it so you don't need a new launch license every time for routine launches)

>>16200974
>>16200960
Something like 0.1 to 1% of Martian soil contains nitrates. You'd have to have nitrate "combines" collecting huge amounts of Martian soil, then sifting and processing it with a huge energy input, something akin to how tar sands are processed in Alberta. You quickly run into a pyramid scheme where the crew required to process the nitrates is consuming more food (and hence, more fertilizer) than they're generating. And that's only one step in the process...

>>16200826
Funny, from what I've heard Jobs was also a sociopath, along with most successful CEOs.

I have been saying that losing a dozen tiles is a literal non-issue. If Elon doesn't think this he is wrong.
-Stainless steel melting temperature and reentry temperature are about the same
-the steel behind a lost tile would be cooled through conduction to all the protected metal surrounding it
-the steel behind a lost tile would be cooled from the gas/liquid from behind it.
These factors make it so that the steel behind a lost tile doesn't reach it's melting point

SpaceX officially released a statement saying it was LOX filter/flow clogging by way of ice. Same happened in IFT-2. IFT-3 managed to get further before they had the same issue.

Sometimes the best part is an actual part (that deals with the problem).

>>16201043
>What's the solution to the water-ice problem?
I don't know enough about their current design to say what would be an effective solution. They seem to be on the right path from the differences between IFT-2 and IFT-3.

>>16201043
It's not a problem and it's not actually real tranny. Show me ONE place where they say it's WATER ICE. the filters were 99% likely clogged by Methane. Not your fucking schizo claim with no proof but twitter

>>16201050

>>16201052
the burden of proof is on you to prove your absurd claim. its all based on EDS nonsense. SpaceX would never make a shitty decision like putting fucking WATER in th tanks.

What's the solution to the jello baby problem?

>>16201050
>Show me ONE place where they say it's WATER ICE.

>https://www.spacex.com/updates/
Fifth paragraph down:

>The most likely root cause for the early boostback burn shutdown was determined to be continued filter blockage where liquid oxygen is supplied to the engines, leading to a loss of inlet pressure in engine oxygen turbopumps. SpaceX implemented hardware changes ahead of Flight 3 to mitigate this issue, which resulted in the booster progressing to its first ever landing burn attempt. Super Heavy boosters for Flight 4 and beyond will get additional hardware inside oxygen tanks to further improve propellant filtration capabilities. And utilizing data gathered from Super Heavy’s first ever landing burn attempt, additional hardware and software changes are being implemented to increase startup reliability of the Raptor engines in landing conditions.

>>16200963
Nope, as others have said there's a reason we distinguish between regolith and soils, that plus the regolith is very toxic, it's full of perchlorates.

>>16201061
NTA schizo.

>>16201050
>the filters were 99% likely clogged by Methane
SX said it was in the LOX lines, not methane

So they need to dehumidify the tanks before filling them with cold propellants?

>>16201004
Eh... I get the arguments but there's still some issues you're missing
>Steel doesn't have to melt to deform
>Discounting the pressure of the atmosphere on the ship during re-entry
>Fuel and Gas isn't spread uniformly throughout the ship
>Issues around over-pressurisation as fuel boils off
I'm sure a solution can be found within a few test flights but seeing a tiles fall off during launch and then seeing them crack away as the flaps actuate in space is a bit more immediate

>>16201071
LOX then you fucking idiot.

how will they refuel a ship on orbit if they will have impurities in the fuel? the refuelled ship will be like a third ice by weight lol. I guess that solves the ISRU water problem because you can just bring it with you in the fuel.

>>16201078
>LOX then you fucking idiot.

>>16201078
That just doesn't seem possible. The freezing point of oxygen is 40 degrees lover than methane. Theres nothing on board cold enough to freeze oxygen.

>>16201083
>Theres nothing on board cold enough to freeze oxygen.

I don't think it was frozen oxygen.
It was maybe impurities in the tank prior to fueling, or maybe the filters themselves failed and clogged the lines. They weren't too specific on exactly where or what clogged, only that it was in the filtration section of the LOX lines.

just show me mammals gestated and raised to adulthood in 0.38g and we can put the issue to bed. you can do that can't you?

>>16201123
show me any animal gestating in space
protip: you can't

>>16201123
There is no evidence of jelly babies, or any evidence to refute it, because the tests have not been done.

>>16201122
mr. space thinks that things other than specific impulse matter when you're measuring how good a rocket stage is. typical mistake made by low-energy minds.

>>16201057
I would pop the bubble. I'd be wearing a ron paul 2020 shirt at the time so people get extra confused about why I did that

>>16201122
But the core of the Vulcan is the 2nd stage.

throat my cock dickhead.

best crew

Go dilate with your SRBs.

Based chaos enjoyer

Much like Musk, the Raptors on superheavy are failing because they are huffing their own farts (autogenous pressurisation system)

fucking tory bruno

>>16201173
what the fuck is he doing

ok apparently it was bullshit, not sure why I thought otherwise
fuck WSJ

>>16201185
this happens all the time. WSJ or some other rag reported that he and Trump were discussing shit like a year ago too. turns out that they were just briefly in the same building. same with the Putin phone call etc

>>16201188
Musk was in a Trump advisory panel before. It's not that loco.

>>16201173
Why is this creep looking at SpaceX scrubs and not his own rockets.

>>16201185
and Starship is landing on Mars in 2020, just as Musk tweeted

>>16201198
the CEO of that company knows way more about rockets than Musk unironically.

>>16201202
He had a lot of time to think about rockets at Blue Origin.

>>16201198
If true, why wouldn't Musk just buy this guy out? Would be cheaper than three more big bombs

>>16201206
Does he want to sell? It hasn't been proven by the only real test. And Musk isn't gonna eat his hat anytime soon.

>>16201198
>to the best of my knowledge
so he's confirming that rideshare missions HAVE lost money. Every time Musk qualifies a statement like this it means it's 100% a lie.
