>It means that most of the IM-1 antenna's signal is bouncing of the Moon's surface to get to us. IM-1 is natively RHCP and when that signal reflects off of something it becomes LHCP. Meaning the direct signals from IM-1 are largely blocked.

House China committee demands Elon Musk open SpaceX Starshield internet to U.S. troops in Taiwan
>The House Select Committee on the Chinese Communist Party sent a letter on Saturday to Elon Musk demanding that U.S. troops stationed in Taiwan get access to SpaceX's Starshield, a satellite communication network designed specifically for the military.
>The letter, obtained by CNBC and first reported by Forbes, claimed that by not making Starshield available to U.S. military forces in Taiwan, SpaceX could violate its Pentagon contract, which requires "global access" to Starshield technology.

Really im supposed to believe this shit can land on the moon after what we saw with nova C? This is extremely dangerous and useless. Even the minimun error could tip it over, Artemis IIIs astronaust are even in a worse situation than starliners

>>16044506

>>16044506
You can always just abort and fly back to orbit if you have too much translational velocity or closure rate or whatever. It's that easy in rocketry when you have return fuel with you.

>>16044506
This thing is going to strand the Artemis-III crew on the moon, they better send extra consumables.

>>16044476
lunar surface isnt a mirror, it would scatter the light

>>16044506
nova C forgot to turn their lidar on. using unfamiliar instruments as a back up is probably the source of the issue and not vertical landings themselves.

>>16044506
wtf does Nova C have to do with it?
You're comparing a little bundle of junk parts with a rocket that has engines and half-full tanks that give it a low CoW.
Have you ever wondered why F9 stages don't fall over on the barge? That's because it's a fucking empty soda can with rocks on the bottom.

>>16044522
Light is a wave, though

>>16044532

>>16044526
Nova-C also has engines and half-full tanks...?

>>16044476

>>16044539
>>16044541

>>16044506
Easy

>>16044568
It's more like two half-empty cans stacked on top of each other. But that is beside the point.

Imagine if the can was fully empty of liquid, and instead of the liquid you put more marbles of equivalent mass into it. That is Nova-C

In desperation to salvage something from the crashed IM-1 moon didn't lander, the mad lads at EagleCam are going to Super Mario Jump their mini probe off the bent bird:

> “We are currently running simulations which show that EagleCam should deploy a total distance of somewhere between 3 to 5 meters [10 to 16 feet], with a best guess at about 4.1 meters [roughly 13 feet],” said Troy Henderson, faculty lead of the EagleCam team.

Pic related.

>>16044584
How will they transmit the footage back to Earth?

>>16044584
Why didn't it deploy during landing when it was supposed to, wasn't that the whole point?

>>16044587
wifi

>>16044549
Final statement:
>According to the number of return photons I go even further and conclude that in all lunar laser ranging experiments the measurements were taken to the bare surface of the Moon.
the data does seem to fit that interpretation. interesting find

>>16044594
I believe they unscheduled the EagleCam deployment when they reprogrammed the lander to use the payload doppler lidar

>>16044415
>>16044418
its ogre...

how will spacex land if the adults in the room cant?

>>16044583
You still don't seem to comprehend just how much denser the LOX is. Look closely at the numbers on that pic. The LOX is only a little bigger, but weighs 3.5 times as much as the CH4.
Now imagine that the bottom half of that soda can is full of mercury.
And even half full, the total of fuel is still clearly all in the bottom half of the rocket.

Wise man once say:
Weebles wobble, but they don't fall down.

>>16044596
That just lets them transmit to the lander, which can't even send back to Earth footage the lander itself takes

>>16044583

>>16044587
> “We have built-in redundancies into this device, with Wi-Fi antenna diversity both in the payload and the lander, which increases our chances of mission success under these unexpected scenarios,” adds Eduardo Rojas, the Embry‑Riddle assistant professor of Electrical & Computer Engineering who designed EagleCam’s Wi-Fi antennas.

Not so much a problem of getting signal back to the crashed lander, but the lander with low power and bad antenna orientation relaying that signal to Earth. And a yatzee roll whether the bot lands with the camera pointing the right direction.

>>16044602
>lox is denser than ch4
So? Both are denser than helium pressurant, no?

I don't see how it matters how dense the propellants are. It's still better to have the mass be mostly concentrated in the engine at the bottom, than to have a larger fraction of the mass in the tanks above it

"Wheeeee!"

>>16044621
its so over...

>>16044506
>It might tip over
Isn't that why they're so adamant about sending the diversity team first?

>>16044568
The header LOX tank sure has a lot more mass than I thought it would

>>16044635
This is the last time anyone's ever going to be seeing this, unless Japan actually decides to build the H3 Heavy.

must be brutal knowing that you graduated training in 2011, everyone else on your 14 person group has flown by now but you've still never left earth. not only that but the group after you has also all flown. even most of the group after them has no flown.

imagine telling everyone you're an astronaut for the past decade and a half and just waiting around at home.

>>16044739
We've always trained an absurd number of astronauts compared to the actual number of crewed missions

anyone else thinking we could probably massively improve tps tile performance if we made them from actual high temperature ceramics rather than fuckin silica?

>>16044767
well they managed to get through the rest of her group and the one after. the crew dragon really helped with that

What would happen if China make it to the moon before Artemis III? I Think itd be a hard blow to NASA, because to the eyes of the public/normies China would be the new biggest superpower in space, and its going to happen the same thing after apollo 11, no one gonna give a fuck about artemis III because the chinese did it earlier

>>16044770
no, actually I mostly think about how we could brute force our way into using cheaper crappier materials for everything.

>>16044776
Nothing, but it would be a black eye for a space program that declared a stated interest in doing something and proceeded to fail at doing it for decades

>>16044777
that can still be accomplished while alongside going to an all-alumina tile, for example.

>>16044781
The only signal theyre getting is reflecting off of the moon. Its actually ogre, I wonder if they get to keep all that money they got.

>>16044784
money was mostly for the cost of the lander/rocket. theres probably not much profit left after they pay their staff. but IM-2/3 give them a chance to redeem themselves in NASAs eyes for future missions

Would an orbit transfer station like this be possible? If you need access to Mars or Ceres/Asteroid Belt you can ride this thing until it gets there if its a large enough station i.e. self-sufficient with plant farms & artificial gravity (not O'Neill cylinders). Maybe you swing by the asteroid belt on the ship to pick up a load of materials from a mine and drop it off at Mars, grab a food resupply while there and head back to Earth to sell goods? I would think of it as the first real space 'ship' like how was done in the colonial period. Not sure how the gravity would work, it would probably be a bunch of joined rotational space stations with boosters attached and separate gravities for Martians, Terrans, Lunarians, Belters, etc. to get acclimate to any locations they get dropped off at. The thing I'm not sure if Earth's, Mars' and Ceres' orbits would synchronize to establish a permanent stable connection for a space station that can consistently go around that fast or if maybe something else could be used.

Eagle Cam bros?

>>16044840
Buckbroken, by me.

>>16044770
How do you make them lighter than just silica?

>>16044839
behold the Aldrin cycler. two stations in heliocentric orbit. one has a fast trip Earth -> Mars and then a long way back (where it would be unmanned) and the other has a fast Mars -> Earth. The fast part of the orbit is the bit closest to the sun.

I don't think it would effect the delta-v to get to mars because any craft would still need to match orbits with the station before docking, but it would cut down on redundant mass for habitation etc.

>>16044878
Ingenius, but couldnt you have allot more stations along their own cycler paths to increase cargo back and forth? I would assume they never cross considering how big space is

I do wonder how they'll fit in a launch abort system, since sticking a motor to a capsule on top won't be an option due to the header tank. Might have to go laterally and only then up and away, which seems like a fun engineering challenge to get to work both in flight and on the ground. The alternative would be something like separating the whole top half of Starship from the fuel tanks, which looks at first glance to be scary because it's introducing a seam into a previously-solid structure and the tile surface. Option C is to just not launch with humans aboard and to embark in space, Artemis style.

I don’t get it, why aren’t we getting pics from the moon? Were they really that incompetent as to mess up comms in 2024? No way, right?

>>16045017

Even if it’s a diversity hire on the ops team who fucked up — the FACT IS they didn’t have a proper double-check process. Could you imagine if NASA or the armed forces made such a clownish India-tier mistake? And chef’s kiss was that it was NASA to bail out the mission from total failure. This is going to be used as pro-government/ pro-NASA ammo forever.

>>16044813
>>16044739
it would be VELY IMPLESSIVE

>>16045036
I suppose it could be used that way, but anyone who did should be reminded that if NASA/JPL made a lunar lander themselves in the present day it would likely cost at least 10x as much as any of these CLPS missions. My understanding is that the CLPS program is meant to help private industry build up some experience in developing lunar landers and give them government money to help them get through the early, amateurish fumbling stage and turn out a solid, reliable product eventually, and afterward NASA can just buy their services for much less than doing it all in-house. Time will tell, of course, how well this works with these small companies. Seems like the big dogs like SpaceX and BO have already poached most of the best aerospace engineers in the US.

>>16044998
Can Starlink penetrate the forest canopy? It's all good if your area has coverage, but if you can't get a signal then its just as useless.

>>16045036
in the end it doesn't really matter, this means they have a problem in some procedures that need to be amended
if they do actually fix it, it is way better to iterate like this than use 10x the time and money to get it perfectly working the first time

Intuitive Machines probably has people smarter and more knowledgeable than anyone here, yet they fucked up anyway. As with Astrobotics, JAXA, Ispace and others. Though one can argue it was due to special circumstances this time.

Of course it is physically possible to land a tall narrow lander that has a significant amount of mass high up. It just means the safety margins for error are narrower. SpaceX might be accepting tighter safety margins because they want to save money by re-purposing much of SS rather than building an entirely new lander from scratch, and they think this is will save far more money than they expect to lose by increasing the risk of failing and having to re-do the unmanned demonstration mission. So it can be simultaneously true that SS HLS is tippy while it also being a rational decision for SX to pursue it.

>Clues About SpaceX's Second Starship Launch Tower! | Starbase Update

>>16045092
the us government has been flying satellites for many years that can listen to normal cellphones, why can't starlink do it?

FIRST BOLE SEGMENT completed!

>>16045211
because those satellites have arrays larger than a football stadium

>>16045218
You want snooping to work even when the cellphone is close to its cell tower and using low power to transmit. Preferably from indoors too.

That stupid lander landed in the worst possible location

>>16045217
I hope it blows up unironically. So much money sunk into this tech and it’s not advancing us one bit

>>16045258
*crashed

>>16045261
It's still in one piece and still works. I would call it a quite successful landing.

>>16045260

>>16045228
looks like hes using his ballsack as a spacehopper

>>16045263
But the balls are not in the right orientation. How can you have a spiritual/cultural significant execution when you 100+ balls with names on the m are not pointed in the right direction?! It's insane to call it successful. You can't recharge the balls' energy when they're not pointed at the Sun. The names of all those wonderful people are now in some kind of multi-billion year purgatory of darkness; permanently belly-flopped - RAPED by someones failure to pay attention and flip the switch to turn the laser landing guidance system on. I can't stand this! I feel like I'm up there with all of those balls, forever.

They lost the technology...

>>16045269
those things didn't even have smart lander tech like the mars rovers. they literally just used altitude data from the radar to guide it during landing. no images etc.
I wonder if they just got lucky and never happened to come down on a boulder.

>>16045268
Those balls are now legal to salvage, right?

>>16044767

>>16045272
Someday - all these landing craft will have little museums around them. This one, too. And no one will know that it tipped over because Western culture was failing at the time and this failure was a perfect representation of that. The plaque will have the names of everyone who worked on the mission, and how it was so successful.

CZ-6C and CZ-12 are both SAST rockets. CZ-10 is a CALT rocket. So the projects use different resources to a large extent.

By the way, I don't think it's particularly important for CASC to hurry with the CZ-10. Many other companies in China are working on F9 clones. CASC is probably wise to focus on projects that are more schedule-safe, to bring more balance to the industry in terms of schedule predictability.

Schedule predictability is important for payload companies. If everyone focuses on new launchers that have a high risk of being delayed, there might be delays that ground payloads for years and cause enormous losses to payload companies and their customers. The risk might cause payload companies to hold back, meaning China might be in a situation of having a lot of launch capacity and not enough payloads to launch.

Since almost all new Chinese rockets under development are similar F9 clones, delays are not independent events. So just because China has 15 F9 cloning projects going in parallel, this does not reduce schedule risk.

Also, CZ-10 has a horrible payload mass fraction. It's a very suboptimal rocket, which I think is because it's a kludge solution that uses parts that weren't designed for it. I think CASC views CZ-10 mostly as a cheap-to-develop tech verification project with which they can get experience with booster recovery before they freeze the CZ-9 design, not as the future staple and workhorse on which the Chinese space program depends.

*of the launchers that have realistic prospects of large scale use and affordability. Solids don't count.

>>16045499
Since they already have CZ-2F and Shenzhou, which are adequate for their space station needs, I think in terms of crewed missions it matters little how long CZ-10A is delayed. Right now they don't have anywhere else to send crew in LEO than their space station anyway.

The CZ-10 is for the crewed lunar missions, and is NET 2027. I suspect that CAST's Lanyue and Mengzhou probably wouldn't be ready for flight tests until around then anyway

>China’s Mengzhou spacecraft, the Lanyue moon lander, and the new-generation manned launch vehicle the Long March-10 have all entered preliminary development stage, and are proceeding smoothly. China aims to send taikonauts to the moon by 2030.

They could get there before we get back, but we'd really need to suffer some further delays to put them into a clear lead. The biggest advantage they've got is that their initial lunar exploration system is so conservative. They don't have to design and perfect any orbital refueling or reuse systems. The LM-10 uses the same tooling as the LM-5 and the YF-100 engine has plenty of flight time by this point. The capsule and the lander are the most complicated parts, but Mengzhou has been cooking for almost as long as Orion and Lanyue doesn't push for any huge capabilities beyond getting crew to the surface and back to LLO.

The other side of the coin is that the real moon race is about who can establish a permanent outpost first, and the various landers and launch vehicles under Artemis give America a pretty big advantage there. China will need something equivalent to the Long March 9 for anything more than flags-and-footprints and that still exists mostly as a PowerPoint demonstration.

I would say pretty high because I have a strong feeling BO's Blue Moon will land the first group(s) of Artemis astronauts.
Starship HLS is a high risk very high reward system (if it works we can build the Artemis Basecamp easily) but it was the only system bidding at the time.

>>16045566
They're running into significant budget constraints too - remember their program is even more underfunded than Artemis.
This would be the most they've ever spent on space.

>>16045531

This is not ideal for LEO as it's using the lunar rocket's (pretty heavy) second stage with 1 less engine as its upper stage hence bad mass fraction and TWR
They can probably optimize it like F9 v1.1 -> B5 though.
What's more important to them I guess is to have a reusable rocket that is crew rated asap.
YF-100 has actually failed twice now so it is below international standards (Merlin and RD-180) for crew.

>>16045708

when did they fail? The CZ-5 and CZ-7A failures were both on the hydrolox stage, no?

>>16045715
The CZ-7A might have been due to a YF-100 issue, but we've never got any official statement about why that launch failed. The CZ-5 Y2 launch failure was due to a turbopump issue with the YF-77 on the core stage.

What use is a moon rocket with no moon lander or capsule?

I guess you could say the longer it takes to develop everything necessary, both rocket and payload, the further away China's space exploration ambitions are pushed. And this is true. But are they really the most important rocket/payloads for China to do in space? Commercial and military applications of space are very important, and aerospace resources are limited.

>>16045753

>>16045577
uh oh

sorry, Pedro left a box of bolts in the LOX tank

So all those new welds are a filter that stretches the width of the tank.

Are the Russians not training new cosmonauts anymore? It's always the same old cosmonauts being launched. These old men must be reaching accumulated days in space numbering 4 digits at this point.

>>16045753
> Raptor engine failed
Uhhh that's bad

>>16045753
Going off of CSI Starbase's model of the plumbing, one of the LOX inlets got blocked by FOD or debris and led an engine to have an uncontained failure. It doesn't seem likely for multiple blockages have occurred since the LOX is pulled directly from the tanks.
Maybe water ice? Water ice is less dense than LOX and would've become an issue near the end of the flight.

They're testing components. It seems to me that YF-215 in 2023 was at approximately the development stage of Raptor in 2014. So they seem to be about on track for the stated schedule of a CZ-9 first launch in 2033, which is not long after a flag-and-footprint landing in 2029
https://spacenews.com/china-makes-progress-on-raptor-like-engines-for-super-heavy-rocket/

>China will need something equivalent to the Long March 9
They have an idea of assembling a base using pressurized moon carts (picrel). Could they perhaps be built light enough to be sent individually with CZ-10?

>>16045777

>>16045792
yeah but that doesn't make sense. they say and one can see that many engines shut off due to reduced in let pressure. just one of them failed explosively.
where's would this common filter be? or was the tank literally full of 20000 ball bearings to clog them all?

>>16045753

>>16045799
The LM-10 should be able to handle an LM truck style lander, but the cargo wouldn't be much compared to Blue Moon and would be next to nothing when compared to Starship HLS. I haven't heard any estimates on the weight of the non-crasher half of Lanyue but the useful payload to the surface can't be much more than ten tons. There's also the issue of just how many LM-10s China can launch in a given period of time. I don't think Bejing would want to use the LM-10 as a base building rocket if it meant they'd have to skip that year's lunar landing.

>>16045825

>>16045014
>Option C is to just not launch with humans aboard and to embark in space, Artemis style
This is the only real option with the current design of Starship, maybe v2 will be wide and large enough for a launch escape system.

It's difficult to imagine a system large and robust enough to secure the really large passenger numbers that musk needs for a mars colony.

>>16045806
There could've been a thin layer of water ice on top of the LOX from contamination during fueling. Doesn't need a common filter if a bunch of water ice shards all got ingested by all the filters at once.

>>16045777
It’s pretty standard given the flight rate of Soyuz, don’t you think? The only russians going to space are doing so every crew rotation for the ISS. So not extremely often (especially now that everyone seems to be trying to keep humans in space for longer and longer durations. Both the US and Russia seem interested in this—which cuts down on the number of active astronauts you really need at one time)
All you need, really, is a reserve of ~20-30ish people who have been up once, twice, three times. Keep them on rotation. Every couple of years a few retire, so you bring in new people as-needed.

Literally just scroll up bozo

7 engines failed.
There was enough FOD in the tank to block 7 distinct filters?
Maybe I'm making a mistake.
Were they feeding from the landing tank? How does ullage gas get into that tank? Maybe there's the filter that got blocked.

>>16045853
>filters
What do you mean

>>16045844
Yeah okay that makes some sense.
If this was the last burn from the main tank and not from the landing tank already then it would have been nearing depletion.

>>16045853
The new filter spans the LOX tank, you can see the welds on >>16045812

>A leak in the aft section of the spacecraft that developed when the liquid oxygen vent was initiated resulted in a combustion event and subsequent fires that led to a loss of communication between the spacecraft’s flight computers. This resulted in a commanded shut down of all six engines prior to completion of the ascent burn, followed by the Autonomous Flight Safety System detecting a mission rule violation and activating the flight termination system, leading to vehicle breakup. The flight test’s conclusion came when the spacecraft was as at an altitude of ~150 km and a velocity of ~24,000 km/h, becoming the first Starship to reach outer space.

>becoming the first Starship to reach outer space.

Starship is officially a spacecraft now

>>16045860
Nope not till it reaches orbit, sorry. I’m absolutist on this. Kinda have to be, given how much I have bashed New Glenn at this point.

>>16045844
According to redditors quoting alleged insiders, the problem was CO2 and H2O ice from autogenous pressurization gasses. The gasses were "wetter" than expected and formed enough ice to clog the filters. These were posted last week before the SpaceX update so it's likely credible.

>>16045863
Wasn’t this a problem during the hop campaign?

>>16045861
>LEO/themosphere is space
Sorry, I’m absolutist on this

>onboard video

>>16045866
I don’t disagree on this now that I think about it

Well, in other news the FAA says Boeing sucks

>>16045867
>the LOX vent plumbing was leaky and dumped LOX into the hot engine bay.
neat

>>16045867
>internally called otf-2
worst version of the name ive heard yet. wasnt even orbital

Space starting at 600km is a bit of a stretch for me, but I agree that it's a bit silly to call 150km "space". It's still cope when we do it. It's at the very least not "outer space", isn't that past the heliopause anyway? Or is that the start of interstellar space?

>>16045872
FAA called it that, SpaceX were more autistic with their IFT

OFT is cooler anyways

>>16045865
I thought that was ullage collapse from sloshing?

>>16045869
Congratulations on becoming an exochad

>>16045863
Elon's best-part-is-no-part autism bites again if true. A dedicated methane/lox gas generator providing heat for an evaporator would've prevented this failure mode altogether.

>>16045883
He's still literally and exactly right about this. This might be the single thing he's most right about. If you never break something because you removed something essential, you haven't taken enough stuff off yet.

>all these failures even with modern technology and advanced computer simulations
Imagine what it was like trying to build the N1 back in the day lmao

>>16045883
Don't they have a heat exchanger for producing ullage on each engine?
That should isolate it from all combustion products.

>france is considering sending troops to ukraine
https://www.reuters.com/world/europe/frances-macron-says-sending-troops-ukraine-cannot-be-ruled-out-2024-02-26/

obviously unlikely to happen, but since France is the major space power of the EU, what would the space battlefield look like in a war between Europe and Russia? i feel like Russia would push Europe's shit in when it comes to space.

>>16045891
according to the insider, they were using the LOX preburner tap-off for the LOX tank instead so the gas had CO2 and H2O in it.

>>16045893
Obviously Russia demolishes EU here (they straight up can't defend against Russian EW satellites) but the latter has America's help.

>>16045894
>according to the insider, they were using the LOX preburner tap-off
LMAO.
maybe they deleted the heat exchanger.

>>16045863
>Someone in the L2 forums pointed to issue out in January. They Best Parted too close to the sun and deleted the heat exchanger, dumping pre-burner exhaust straight into the lox tank. This works well for pressurization but there’s a tiny little issue.

>You dump hot CO, CO2 and H2O into the lox tank. What happens next? The gases condense, run down the walls of the tank and then form ice (and dry ice).

>This ice floats. Everything is perfect *until* the booster flipped over. Then all the turbopumps choked on slurry.

>>16045890
Honestly easier because despite their large sizes, both Saturn V and N1 were specifically designed to be overall-simple - with only strategic hurdles needed at any given time along the production process.
N1’s only problem was that it was being built by Russians. What’s worse; Russians under the USSR government. What a disaster, no wonder it failed!

>>16045894
>>16045899
This is so based actually. Best part is no part.

Untestable single-fire engines built by Russians

>>16045907
And there's not even an indication they reversed that decision.
Dumping water into your propellant tank to own the libs.

>>16045744
Hey faggot. Ever think that license time can drop from previous expectations? You should maybe go fuck yourself.

>>16045913
They added a filter to catch any ice.

Having to go back a step means you sufficiently Best Parted.

>>16045799
>surface habitats
i prefer the lavatube penetrator version

>>16045087
A lot of people don't pack a compass or a map or anything else. Or for that matter, they don't take a stock of their cardinal direction when they leave civilization behind and make a note of it, so that if they get lost, they have a direction to focus on to return to it.

And then as others have said, the overriding of logic caused by panic.

>>16045142
A managed democracy would lead to population collapse anywhere but Earth because of the extreme environmental hostility that exists without a stable local biosphere. The biggest weakness with democracy is that popularity matters more than ideas or merit. Trump won in 2016 despite having 0 political or governance experience, because he knew how to talk to the audience and worked the system in areas where his opponent, too arrogant to see her own weakness, ignored the constituents. Thereby ensuring that he locked in all core votes necessary for victory.

It's possible for a technocracy to eventually transition into a direct/managed democracy, but not vice-versa, as the probability of meritocratic decision making is unlikely to succeed due to inherent biases of humans bubbling up with our desire to be tribal no matter where we go.

>>16045913
when you have a high production rate they let you do it

Just about everyone who dies in the wilderness these days does so alone. Never hike alone.

That doesn't sound very rapidly reusable if you have to clean your tanks of combustion products after every flight.

why so schmooov?

That's cgi?

How would you change bikes for a huge low g shirtsleeve environment?

>>16046071
Tune up the suspension but that's about it. Bikes are simple things. Even for lunar ops an electric dirtbike only needs different wheels and suspension settings.

There’s so much SpaceX cock-sucking it makes me super suspicious of any good news or hype re Starship. The company doesn’t seem to be suffering under a terrible competency crisis as most American tech companies are — but it’s seems out-of-order how MUCH failures they suffer with core tech. Yes Elon arrived on the scene at just the right time to exploit the battery revolution and yes he was able to execute on major government contracts and thereby secure the funding needed to grab up the best orbital bands — but it needn’t have been SpaceX it could have been anyone who grabbed that business. SpaceX was competent enough to successfully execute on that government work which in the end of that is all that matters — but I feel like soiface propaganda constantly bombarding me about how awesome Starship is going to be when all I see are failures. Can someone explain?

the real red pill is hydrophobic ceramics. TPS absorbing water was a big part of the problem the shuttle had. It needed a weird fucking coating or else it'd absorb water like a sponge. Hydrophobic ceramics might not have this problem.

>>16045829
Need to purge the tanks and lines better, thats it

>>16046128
anon they're literally dumping preburner tapoff into the tanks to pressurize them during flight, that's going to cause a lot of ice to freeze out and clog things if the filters aren't up to task

>>16045883
Thats why you test
A better filtering syatem might be cheaper and lighter than a heat exchanger

>>16046131
so it wasn't all the bird crap, bugs, and loose metal clogging up the filters?
>>dumping preburner tapoff into the tanks to pressurize them during flight
that sounds retarded, but what do I know

>>16046056
Just flush it nigga, how hard can that be

>>16046131
fucking source?

Realistically how long will it take for BO, Relativity, Rocket Lab, ANYBODY to get to SpaceXs cadence?

>17 corrective actions
What are the 17 corrective actions?

>>16046131
Just make better filters

>>16046147
17 payoffs

>>16046098
when i make this kind of bait, i write considerably less. and instead of SpaceX write it as "space-x"

>>16046122
Right now it sounds like they're stuck trying to finding a good site for their orbital launch system. They were thinking about Hawaii but that went about as well as you'd expect. Now they're looking at some spots in Alaska and Australia.

>>16046098
it's simple: you're retarded.
