So anyone have any speculation as to what happened with SN9’s Raptors? I’m with the theory that the Raptors are fine but somewhat scuffed. I also think that SpaceX is worried about optics with the upcoming HLS selection.

How do I suggest new ideas to squad?

Dumb statements. The elements are distributed according to Gods plan.

>>12585710
God only ever rolls dice

>>12585709
Nothing, it's a myth.
Mueller came in and handled a lot of early and middle stage Merlin development, Merlin 1D was the final evolution he led, Merlin 1D+ was mostly handled by the SpaceX propulsion team rather than his direct leadership, and he had basically no involvement with Raptor at all. This is actually the ideal thing to have happen because the entire SpaceX team is less likely to simultaneously have fatal aneurisms than one guy and doom the projects they're working on to development hell and eventual cancelling.

>snine status: overbudget and behind schedule, hop never ever

Not a china shill, but what if zhenzhou would have been the original soyuz designed by the soviets?
The ability to leave a miniature space station in orbit would probably have been really useful back in the day

>>12585810
It’s really neat. I’m a huge fan of Chinese Station design because it’s so Soviet. They even have their own version of the TKS.

>>12585810
Kind of a neat idea to expand your station with every crew rotation, so long as you have enough nodes to spare. If those little things are standardized you could build a little hotel with individual suites, that'd be kinda cool.

>>12585643

This is big if true TM, because no one's been able to manage >80% mass closure.

>>12585891
What’s he doing in Boca Chica? He’s just another NASA astronaut right? There’s no way that’s related to HLS progress is it?

>>12585900
It probably is HLS related lol. Even if it isn’t, Johnny and NASA seem very interested in SNX

>>12585881
based

>>12585900
Maybe meeting with Elon or who knows what the fuck astronauts who aren't flying do during the day. I imagine most astronauts on Earth who aren't actively preparing for a flight just sit around most of the time.

>>12585923
Yeah I’ve wondered about that. Some astronauts sit for over a decade without flying. What do they do? Consult with scientists?

OOF. Maybe that tip was more of a problem than they thought. To be fair that would have scrapped any other rocket

>>12585934
eda also has good sources. Interesting that he specified "human error"

>>12585934
fuck we'll be lucky to get orbital this year

>>12585934

>>12585937
idk I always thought that that was a stretch. Cutting-edge dev ALWAYS has unexpected bumps

>>12585934
'tip'?

>>12585934
They should just get SN10 rolling. How’s she doing anyways?

Alright then, since SN9 is having issues, what are the odds 10 flies before 9 then?

>>12585936

>>12585932
I doubt it. They're not there to give their technical opinion or participate in the design process (other than usability design of the cockpit, I suppose), they're there to risk their lives for the chance of going to space. When they're not doing that, they're probably on press tours or literally being paid to do nothing.

>>12585945
do they have the raptors for 10? I imagine raptors are the bottleneck here.

>>12585955
They’re at like SN60 with the Raptors it’s insane. By the time a Raptor is at Boca Chica it’s already obsolete.

>>12585934
oh, ok so he doesn't know as much as that post implied

>>12585979
I mean at this point they could probably just send SNX (sex) over there. SN9 did a good job of showing how Raptors can function even while damaged.

Spacex is finished.

>>12585897
They probably just eat each other or something. What CCP does is not applicable to normal humans.

>>12585959
This, this is also why it's okay that they keep eating them at Boca, they already know they have better shit in the pipeline and there's no other purpose for the older engines

>>12585987
>SNX (snecks)

>>12585946
I bet SN9 can provide valuable data that might be useful for when a starship is damaged on the Moon or on Mars. It's perfectly reasonable to try to get it to lift off the ground, especially if it RUDs afterwards.

>>12586106
pretty lame if these raptor issues are known problems that have been fixed and they pushed back testing for a week at least for no real reason

>>12586005

>>12586084
wake up, you've been living in a dream world bezos

>>12586114

>>12586111
Again it's important to consider the environment that these engines were being fired in. They weren't on the test stand, where they would have been fired several times in the past. They were on the ass of SN9, pointing straight down onto a concrete slab, and as we've seen before this makes the concrete cry out as it strikes the vehicle. Those two engines could have had something as simple as a chunk of rock strike the nozzle and put a deep enough dent in there that they decided not to risk firing it again. I highly doubt that either of those engines is totaled; I also doubt that we'll see them ever again, because it's probably faster for SpaceX to just pick out another two fresh from the warehouse than to try to go in and repair those engines.

They will do at least that one module NASA contracted them for. And even that will improve the ISS greatly, because they were waiting for it almost two damn decades already.

>>12586462
Elon says a few hours at most, but they also have to test the new engines so effectively it will always be a couple of weeks minimum until these engines have a few thousand throosts on the books.

>>12586445
>>12586453
say what you will about delusional anon, but had he been running the show, that static fire woulda been one and done, and we likely wouldnt be waiting till Q2 for SN9 to hop

>>12586465
it's a lot more than that, boyo

>>12586459
Yeah I suppose you would have to be delusional to think that it will take only a week.

>>12586465
no, he said it "needs to be" a few hours at most. That's his aspirational turnaround time which means currently it's orders of magnitude longer than that.

i wonder how many of these old space dudes almost shit themself while SN8 did it's backflip, only to relax when it exploded.

>>12585934
Well Musk did say they will have to do static fire after two engine replacements. So that will take a while. Remember the last time engine replacement took a while. While Musk wants it to happen in few hours, its a stretched goal, not an immediate goal. So I expect atleast a week away, maybe 2-3 weeks for proper static tire test and results.

some of them already have towers and equipment for the cable cams. I would think it would have to be a very bowled stadium, and would need to have radio-reflective material placed over all the seats. However the shape of the seating is definitely not the right parabolic shape for a parabolic antenna, you would need to build structures where the seats once were. you have a point though that it provides a good existing underlying structure that you could then build a scaffold over.

thx, yeah with some modification, not straight from grass. https://www.youtube.com/watch?v=vKYjCmD7m1Q

ok nvm probably too much radio noise

>>12586836
yeah, landing with solids is a pretty insane thing to even try

so when are we getting liquid hobby engines

Geoff who?

>>12586910
As soon as I move into my new place I'm starting on a hobby ion thruster

>>12586910
Building your own engine is certainly a possibility, considering people build hobby scale afterburner turbofans at home. Ethanol would be a simple fuel but fuck knows how you could possibly manage liquid oxygen at home.

spacex stans on suicide watch

>>12586939
2/10 you put in a little effort.

>>12586910
You can buy COTS hybrid engines from some companies. Pure liquid engines, never ever. Like >>12586934 said, good luck convincing somebody to sell you lox not to mention storing it, and if you try to make your own hydrazine/N2O4 you'll probably kill yourself and all your neighbors

>>12586879
One word: passion

>>12586934
>>12586946
You can make LOX at home

>>12586951
This

>>12586951
Tiny (millilitre) quantities in a test tube perhaps, making any substantial amount would require very large amounts of liquid nitrogen and a way to store that. Then you need a way to store your liquid oxygen at -150 or whatever.

>>12586763
I'm half convinced that WAS a 4ASS mole. They painted a rocket like a 1990s disposable drink cup, snuck a Hitler joke into the mission name (National Socialism - 14 Words), used the wrong units on purpose to trigger everyone watching the stream, tilted like a drunk walking home from the bar, and fell the last ten meters or so unpowered.

>>12586946
Can you make a propane/ethanol engine? That would be room temperature storable and you can buy your propellants at hardware stores.

>>12586965
not sure where they got it but I've seen youtubers use lox + propane for vortex engines. https://youtu.be/tqEfbJRKzeQ

>>12586965
Yeah I can't see the average joe being able to make enough to power a significant rocket. What would a more available alternative be? I know there's a few hypergolics that aren't especially hard to make, but they are way to dangerous/toxic to really be feasible.
I know that nitrous oxide is more available since they make those nitrous oxide/paraffin hybrid engines.
>>12586976
There's no oxidizer in that blend, you've just got two fuels mixing. I did see a nitrous oxide/ethanol engine mentioned in passing in an internet search, that could be interesting for a hobby liquid engine, although I think the nitrous oxide would be a gas in all likelihood but whatever
https://www.researchgate.net/publication/305620863_Development_and_testing_of_a_nitrous-oxideethanol_bi-propellant_rocket_engine

>>12586965
You can build an air liquefication setup with some pretty basic components and a little gumption

>>12586981
wait, I take that back. Upon watching it again looks like he was using liquid propane + gaseous oxygen

Not this one. I don't know when they'll try again, but it seems like they built in some time between the last and next recoverable boosters to make adjustments. When they do, they'll probably just parachute it into the ocean again for now.

I poked around and it looked like it had a cover that just popped right off like a fairing. When through the rest of the flight without a covering.

this but unironically

how far could 4ass go if it stopped being a meme

>>12587142
It’s great to see the plumbing be tested but the RS-25s have been active for 40 years. It’s not some huge breakthrough like Raptor.

Now that I ponder it some more, they have to be thinking IPO. With space becoming more popular as an investment sector, a successful OneWeb IPO could be extremely lucrative. Look how well Virgin Galactic stock is doing and they're still far from operational.

>>12587265
OneWeb just seems to be unlucky. They’ve been building sats before Starlink even was announced yet they just aren’t fast enough.

>>12587280
for real?

Simple math. A warship with a mass of 3,500 tons, plus a 500 ton Nuclear Salt Water Reactor engine with an ISP of 67,000 seconds and a thrust of 12.9 Meganewtons (12900000 Newton’s) could reach 0.15% the speed of light with 4000 tons of fuel (and a dry mass of 4000 tons) when traveling on a one-way trip, or 0.075% the speed of light if it decelerated at its target. At 0.075% the speed of light, our ship could travel 30 AU (the distance from Neptune to the Sun) in just 8 months. Said vehicle would be able to thrust at 1.6 m/s^2, or 1/6th Gee with a full tank, and 3 m/s^2 with an empty tank (1/3rd gee).

VEHICLE STATS
MASS: 4000 tons dry. 3500 ton Warship plus 500 ton engine/reactor
MASS WHEN LOADED: 8000 tons. 4000 tons of propellant used.
ENGINE THRUST: 12.9 Meganewtons
ENGINE ISP: 67,000 seconds
VEHICLE DELTA V: 454,000 m/s
VEHICLE TOP SPEED WITH DECELERATION: 227,000 m/s, or 0.075% the speed of light

Is SLS actually possible this year if fire test is successful?

technically yes. feasibly no.

Yes. SLS has been done for a year now

Allright boys, post your best oldspace copes

No engine tested at Stennis has ever failed. Can Space-X Buca Chuca say the sane? I'm waiting...

>>12588045
There will be more working RS-25s after the SLS test fire than there were Raptors after the SN9 test fire. Just saying

>>12588053
probably because they've been tested at stennis only after the shuttle era ended, after 40 fucking years of service

>>12588059
nope, nasa said it on stream today. so you are wrong

Was oomoouhmoouh an alien ftl spacecraft and if so how can we contact it?

>>12588055
>there will be more of an engine that has been flying for 4 decades than there will be engines that first test fired 4 years ago.
I'm not the kind to suck Musks dick but do you actually think that is any kind of proof SLS isn't shit?

We don't, they just fly one past every century and when we can move it into LEO for study they know we are worth talking to.

Clean SRBs could be the future

>>12588166
What does a "clean SRB" burn and how is it cleaner that hydrolox's water exhaust?

>>12587650

the dumbest part about posadism is that it is actually a logical extension of marxist ideology. essentially, marxists think that human societies follow a predictable path based on their level of economic and technological development, with communism being the final stage of that. so, if you buy into that shit, it does make sense that aliens, who are technologically advanced, would also be communist.
