Old thread >>10799324

ooooooh
flare stack

Launch (hop?) thread will be up mid day tomorrow.
I'll have to modify my template, hah. It'll be the first Boca Chica launch thread. Don't forget your snacks!

>>10807544
when did musk originally say it was gonna hop?

>>10807575
Tuesday, and I still think it's set to be tuesday

>>10807575
Tuesday, presumably after the Neuralink thing

>>10807575
about a month ago, but Raptor wasn't ready
they had a few resonance issues
Tuesday is the latest date with the updated Raptor and is looking pretty reliable

preburner

>>10807606
looks more like LOx prechill to me

>>10807606
Looks like some cryptid rather than a test rocket. Maybe if you desaturate the image, add a film grain effect, and post it on /x/ with some creepypasta story, then maybe /x/ would take it seriously.

>Starliner launch delayed to 30th November giving Dragon 2 an earlier launch date of 15th November proving it passes the Crew Dragon in-flight abort test scheduled between late July - September
The ABSOLUTE STATE of old space right now...

>>10807691
why can't oldspace into aesthetic

>>10807697
I kinda like the look of Starliner, looks more pragmatic than Dragon 2, not a slight against Dragon though.

Boorman's excalibur vibes

>>10807709
it discards too much with the serval module

>>10807714
You have a point, but I was just talking about Aesthetics.

>>10807713
What's the deal with the flame? I'm curious what the purpose is.

methane flare mhttps://en.wikipedia.org/wiki/Gas_flare

>>10807718
le penis rocket
>>10807719
they poured a bunch of liquid methane into the hopper, but it's uninsulated and they don't have the ground service equipment they need to scavenge all of it out of the hopper and put it back into storage. So they burn some or all of it.

>>10807714
>Serval module

>>10807722
>le penis rocket
It's unavoidable to make phallic objects in aerospace. If I had a nickle for every time freshmen snicker at that, then I would have enough money to buy a ticket on New Shepard.

>>10807727
yeah but it's got the mushroom head
if you're going to make a rocket at least have the decency to look like a dildo, constant radius or decreasing radius only please
large fairings on the tip only work when they're long enough to not have exactly the proportions of a human glans

>>10807728
Any reason why Starliner is as wide as it is? The Atlas V diameter (3.81m) seems wide enough for a capsule.

>>10807732
how many people does it seat? was seating as many as shuttle (seven) really a requirement?

>“We are more than halfway through the largest test campaign at Marshall since articles from NASA’s Space Shuttle Program were tested here,” Honeycutt said. “With the delivery of the liquid oxygen tank test article, we’re entering the final stage of Space Launch System structural testing.”
Be honest /SFG/ Will it make the June 2020 deadline.

>>10807736
>how many people does it seat?
I think it can seat as many as seven.

>was seating as many as shuttle (seven) really a requirement?
Probably not for regular service, but my guess is that NASA wanted the capsules to be able to hold up to seven astronauts in case of an emergency evacuation from the ISS and only one capsule is available

>>10807744
I think SLS might just actually fly
I don't think it'll have anything to do when it does, Congress never told NASA they were allowed to do anything with it, just that they were to develop it.

>>10807744
>Will it make the June 2020 deadline?
I doubt it, my guess is early 2021 if nothing bad happens during testing.

>>10807744
If Bridenstine skips the green run (which it is looking like he might), 2020 is easily doable, but the risk of an after-launch RUD goes up significantly.
If he doesn't, 2020 is only possible if the god of luck has literally everything go perfect in testing and nothing gets delayed or slowed even a tiny bit.

>>10807732
Starliner's design started as Boeing's bid for the CEV, aka what we now know as Orion. This is part of the reason the diameter is big. The other reason is...
>>10807736
Both Starliner and Dragon V2 seat 7, so I think a crew capacity similar to shuttle was a requirement. Back when it was the CEV and flying on the Ares I, Orion could carry 6.
Two of the seats were dropped when Orion was retooled for deep space missions to make room for the extra equipment needed.

>>10807744
>>10807757
Oh wait you said JUNE 2020.

Yeah, maybe if the Green run is skipped, since they're saving 6 months, they could make June.
Literally impossible if the Green run isn't skipped though. At best, they'd make a December 2020 launch with the Green run in the schedule.

they're proceeding through the preliminary testing much faster than the last time they tried this, which gives me confidence that they've mostly figured out their clathrate problem

>>10807047
last I heard, the GSLV-III polar moon shot encountered problems when loading cryogenic propellants and is delayed at least ten days.

Next scheduled launch is the final Soyuz-FG taking crew to the ISS on the 20th.

still venting, wow

I fully expect an Apollo 11 sticky beginning on the morning of July 16, and ending on July 24. If the moderators are worth their salt (they aren't), then this will happen.

This rolling sticky should also be billed as the default /SFG/ of the board for its duration.

what are YOU doing to prepare to become a future spaceman, /sci/?

Giant mechs on the moon to insulate against the dust and because of grav allow you to have large lead shielding and do lots of labour think avatar

>>10808008
lead is bad shielding, your ignorance is showing

>>10808016
is it kosher to be walking in the shadow of the flarestack? it's a ball of fire two stories tall

>>10808003
I'm a slum-lord in progress, and I'll use that money to fund larger real estate ambitions, and that money will fund some LEO business, and then I'll mine aluminum and water on the moon and sell it.

After that, 16 Psyche. After that, gas giant moons. After that, I'm getting the fuck out of here.

>>10808029
it's pretty far away

>>10808012
Depends on the kind of radiation retard

>>10808042
GCR interacts extremely poorly with lead, which is your primary concern on the lunar surface

>>10808032

On the exact contrary. You will die alone (every human dies alone) on the same sphere where you have had the pleasure to exploit nigspics, and to be yourself a Worthless Eater. Embrace the nihilism of your own Unbecoming. The very fact that you are old enough to be a landlord augers well for your final immolation. Most importantly of all, /none of your issue, if you have any, will escape either/. Nature has beautifully conspired (the emptiness and hostility of space, the speed limit of light) to place certain qualitative limits on such wishes for Flight from the World (from other shitty, poor lesser beings that 'I' would escape). I do not even begrudge you for wishing to escape humanity (I know very well how terrible it is to associate with stupid/poor people). But what I take pleasure in, is knowing that where it really counts, you are the exact same as everyone else, and will meet the exact same one undifferentiated end. Your money won't save you.

This is not a political statement. It is a simple statement of fact, and a happy one at that. "At the end of the game, the king and the pawn go back in the same box" -a cute, presumptive 'Italian proverb'

>>10807945
>This rolling sticky should also be billed as the default /SFG/ of the board for its duration.
No. There's too much other crap that happens in here. And let's let the retards troll the moon landing over there.

>>10808066

What a stupid post.

>>10808071
YOU DON'T BELIEVE IN FOUR-SIDED SPHERE EARTHS ?

>>10808058
I can smell the mental illness from here. Also-

>old enough to be a landlord
You could have been a landlord in your early 20s also if you weren't dangerously inept.

>>10808049
I may not know about lead, but isolating humans from dust seems imperative. Say you use some plastic composite, or some water ice. What are the potential for giant robots anime on the moon for construction/mining, etc? What are my chances doc.

>>10808088
just use a forklift m8
lunar dust is not a big deal

>>10808088
The clear answer here is some kind of resin/fiberglass mix that gets sprayed down around inhabited areas, to create a dust-containing mat. For equipment and people coming back to the base, there would be some kind of decontamination area or change-over station where people get into clean suits or vehicles so as not to track regolith back to the main habitat.

>>10808097
>>10808090

gotcha. To be honest I was wondering more broadly because of a disagreement I had with a friend. Bar logistics it seemed to me that because of gravity and regolith, as well as radiation and long days the conditions on the moon were worse to start out on. Things like internal bleeding would be lethal. And really the only advantage is minerals you can't readily get to and steady supplies.

He didn't weigh any of the problems I listed as all too relevant when compared to the 6 months travel / 2year window. And I didin't really have an answer for that, other than starships at scale because they are cheap. And every two years you produce very many of them or something/cheap subsided travel

>>10808086

I had the early 20s low-ball in mind when I wrote the above (there is no escape velocity to which the very young and very rich can really aspire. This, because they are still helplessly dependent on the cooperation of other human beings and supply chains to effectuate their will). Assuming you're the same poster (though this applies to all human beings), you're going to die alone on earth. Cope, dilate, and eat shit faggot.

>>10808066
in some alternate reality, there's an actual conspiracy to make people believe the earth is flat, and the globe-earthers trying to reveal the truth make posts like this.

It looks like they've got a crew up doing something to the engine on the hopper.

>>10809435
it leaked through the check valve because check valves don't work in zero g or maybe they turned the capsule upside-down at some point

Thanks

>>10809389
>It is worth noting that the reaction between titanium and NTO at high pressure was not expected. Titanium has been used safely over many decades and on many spacecraft from all around the world. Even so, the static fire test and anomaly provided a wealth of data. Lessons learned from the test – and others in our comprehensive test campaign – will lead to further improvements in the safety and reliability of SpaceX’s flight vehicles.

that's "things hitting titanium while it's dunked in NTO", not "freshly exposed titanium metal exposed to high pressure/temperature NTO"
the willingness for Titanium to go up in flames should not be underestimated

>>10809514
Wait, if they already tested all the components themselves, then the only thing they're testing on such a run is the integration of the components... which they would then un- and subsequently redo anyway. Seems like a waste of time. Especially since they can't test the full range of forces it'll experience during flight anyway.
Just launch the fucker. It's a fucking test run mission anyway.

A high speed high pressure slug of NTO would create a water hammer (tetroxide hammer?), so 60ft-lb of impact force doesn't seem unlikely.

>>10809787
anyway, titanium has a habit of unpredictably bursting into flames when exposed to oxidizer

>>10809791
oxidizers, man. they're just too hazardous, we should switch to high thrust gas core open cycle nuclear engines instead

>>10809809
no

>>10809744
They might do that.
The main risk is skipping it means not getting full data on how the various systems interact. In particular, they're worried about the systems and fuel plumbing in the engine boattail.
Skipping it is risky because even if no negative effects manifest during Artemis 1, if a serious issue's found during the green run for Artemis 2 (which will definitely NOT be skipped), they won't be able to fix it without delaying Artemis 3.
The SpaceX style of flying as a test works better when you don't have a once-per-year launch rate.

>>10809395
>if it happened during in-flight abort
>complete loss
That would have not only made the abort test much more """fun""", but they wouldn't have the debris conveniently in one area on the ground to pick up.

>>10809407
I think that was the plan, to reuse crew Dragons for cargo, but the only thing keeping them from using "flight proven" capsules for non-NASA passengers is the desire to focus on Starship, and maybe lack of somewhere to go other than ISS.

>>10809424
>they stopped the production line for the old cargo capsule, so no more Dragon 1
I'm guessing they may keep a couple around in case there's a need for the extra width of a berth docking.

>The LightSail 2 mission team has delayed deployment of the spacecraft’s solar sail until at least 21 July 2019 to conduct additional attitude control system testing and potentially update the spacecraft’s flight software. LightSail 2 remains stable and healthy in orbit, and returned another picture to mission control at Cal Poly San Luis Obispo in California.
>With its solar sail stowed, LightSail 2 will remain stable in its current orbit. Once the sail is out, increased atmospheric drag will limit to about 1 month the time the spacecraft can raise its orbit. Therefore it is critical that the attitude control system is working as expected prior to sail deployment.

Only bit of new information, really

>>10810039
It's useful if you haven't got a power supply or mass to carry around a chemical, nuclear, or MPD propulsion system, but without say a powerful laser propulsor station once you get out towards the orbit of Mars it becomes incredibly inefficient. We're talking square kilometers of sail for significant payload masses, and in the belt and outer planets and the Oort cloud they're only getting a tiny bit more propulsion from the sun than they are from other nearby stars. Since we don't have any massive solar or nuclear powered laser generating booster stations they can only operate effectively in the inner planets, so yeah, cheap lightweight satellites within the orbit of Earth or nearer to the sun can benefit from them.

Anon, you don't seem to understand how government contracting works.

>>10810431
>>10810441
Neither of the pads at LC 39 could handle the full-length firing of an SLS core stage. It's only designed to handle the minute or two the exhaust gases from the engines impinge on it.
A static fire would be conducted at pad 39B if the green run is skipped. But it would be comparatively brief.

>>10810441
Fun fact: like the shuttle, the SLS does not require actual hold-down clamps, per se. The weight of the vehicle itself holds the rocket down on the pad prior to SRB ignition. In fact, the whole rocket rests on the SRBs while on the pad. The core stage is "hanging" from the thrust beam.

>>10810555
Why not? most of the heat is from the SRBs, isn't it?

>>10810560
If you watch a launch video, the time the flame trench is exposed to the full force of engine ignition in a normal launch is comparatively brief. Maybe about 10-15 seconds. Even without the SRBs, it's just not designed to handle those stresses for such a long period.

>>10807544

it's a flying engine test stand

>>10810577
Fucking this.
They just slapped some aluminum foil on it because SpaceX are (apparently) marketing geniuses that somehow figured out how to make even fucking ENGINE TESTS hype.

So is there a time for this or is it just tomorrow sometime? Normally SpaceX is better at providing times.

They shoulda given NASA the finger when it came to propulsive landing, that way they wouldn't have to deal with rust in the internals having bad interactions with hypergols. Also it would have been really fucking great to watch capsules land propulsively.

>>10812189
>They shoulda given NASA the finger when it came to propulsive landing, that way they wouldn't have to deal with rust in the internals having bad interactions with hypergols.
Post-Shuttle NASA is far too safety oriented to let SpaceX do that. If SpaceX did try that, then most likely they would've been kicked out of the commerical crew program.

>>10812259
On one hand you could say it wasn't worth the delay, on the other hand you don't have to deal with the possibility of seawater rust causing your hypergols to ignite incorrectly and RUD your capsule. Shit isn't one of the other next-gen capsules going to do a dirt landing with airbags? Even that would probably be better than an ocean splashdown.

Once we have laser propulsion sails will be an effective way to move less time-critical supplies and vehicles around the solar system, or reduce overall propellant requirements for acceleration if they're outbound or braking if they're inbound.

>>10812799
Very funny, but no. It's just a cartoonish reenactment of the general feelings I get from others who are not into spaceflight. They feel that spaceflight isn't important at all, apart from the basics like satellite tv or weather monitoring. I even encountered one person who told me with a straight face that "we know more about the surface of the moon than the bottom of the ocean, shouldn't we instead focus NASA's budget to explore that than space?" in a college discussion about if NASA should get a larger budget. I'm sure it's not a common sentiment, but it's far from rare in my experience.

>>10812799
Learn English.

>>10812816
>I'm sure it's not a common sentiment
Don't be so sure, I've heard that line myself more than once.

>>10812792
Yes we need to send NASAs budget in the form of food aid to Africa so they can reproduce more and we need to send them more food.

>>10812816
NASA's budget is fine. The problem is NASA adminstration's lack of oversight on their own spiraling project cost over runs. Did you know that SLS was supposed to fly in 2016? Before its first human flight, it will cost Americans ~$70-$80 billion dollars? All the delays for their project and what did NASA do? Give the contractors BONUSES.

>>10812822
Well that just makes me sad. Dealing with that point requires unwinding so many misunderstandings and ignorance that just makes one feel like they're playing chess with a pigeon.

I just wish more people took spaceflight seriously. I'm not expecting people who know and understand the history of spaceflight back to Goddard, but I want people to see spaceflight as seriously as they see the maritime industry. Only the most ignorant people would say that maritime trade, research, and industry is pointless or wasteful or silly. Yet a not-insignificant number of people would feel that way towards spaceflight, despite the fact that it is becoming just as important as maritime.

I'm not sure why people feel that way, I don't study culture, but my guess would be spaceflight's strong association with nerd-culture (which is still seen as negative), and the fact that (at least in America) spaceflight petered out really quickly after Apollo and didn't maintain a presence in the American pubic eye. Although, it did seem like the public didn't like Apollo all that much already, with it only getting a 50% approval rating at best.

>>10812650

>>10812837
isn't NASA's budget a rounding error against the food aid sent to Africa?

>>10812841
>NASA's budget is fine. The problem is NASA adminstration's lack of oversight on their own spiraling project cost over runs.
I know this now, but I had that debate when the SLS was "brand new", so the information about just how poorly NASA manages it's contractors wasn't super common yet.

>Did you know that SLS was supposed to fly in 2016? Before its first human flight, it will cost Americans ~$70-$80 billion dollars? All the delays for their project and what did NASA do?
Yep. And I know what's coming.

>Give the contractors BONUSES.
That still pisses me off so much. I do support the SLS, I understand the importance of having it (apart from giving contractors money), and I want it to fly. But that thing NASA did, not just a single mistake they did this over and over, is the reason why I will talk trash on that garbage fire of a rocket. That act NASA did was shameful, and the management inside that allowed that to happen should both be fired and bared from having a leadership position that's higher than a McDonald's manager.

>>10812195
NASA is embezzlement orientated, not safety

>>10812851
>the importance of having it
New Glenn, Vulkan, and OmegA with distributed launch can all replace everything it's capable of.
Starship can replace it with orbital refueling, and has a few extra capabilities besides.

>>10812863
True. But SLS has one key advantage over all the other upcoming new rockets, it can be launched first. Sure, that advantage is losing strength because it has been delayed for so long, but if there were a sudden need for a super heavy rocket then the SLS can be there. Now the SLS comes with some nasty management that would definitely get in the way of that, but the possibility was there. The SLS could've been the last hurrah of the "Shuttle era", not the best, but useful until the gap was filled by the new era rockets.

Then again that's bordering on alternate history.

>>10812606
What's all that gas it's venting?

>>10812902
Liquid oxygen vapors, which mostly means what you're seeing is water vapor that's been condensed out of the air by the extreme cold
basically it's steam

>>10812902
LOX to prevent pressure buildup as it boils off

>>10812902
the fire on the right is a methane flare for the same purpose (burn off excess methane as the methane boils away)

>>10812906

>>10812926
it's a flying engine test stand, and the tethers are loose, so even a static fire involves the whole thing rising a foot off the ground

>>10812932
They already loosed the tethers? Then isn't this it's first true untethered flight, even if it only goes a foot?

>>10812937
no, the tethers just suck, they're not hard hold-downs like on a launch pad, they're just straps

>>10813018
Are RCS systems normally loud? I don't think I've seen one used at ground-level before.

>>10813022
it's high pressure nitrogen, have you ever opened a high pressure air line

>>10813018
There's a twenty foot tall liquid nitrogen tank outside the building I work, and every time it vents when I'm walking past it scares the bejesus out of me because its so fucking loud.

And that's just incidental pressure release.

>>10813025
Can't say I have, but it's not hard to picture it being pretty deafening, depending on the pressure.

>>10813014

>>10813031
>>10813034
80 psi 1 inch line is deafeningly loud, and that didn't have a rocket nozzle on it
air is 80% nitrogen so I'll assume it's the same
also you should always be wearing hearing protection around liquid nitrogen tanks
