not really, it means they are trying to launch it sometime this fall
doesn't mean they are going to succeed

>>16230566
I hope they show some ITAR protected stuff

>>16230571
they won't

>>16230569
Surely the fact they are putting in the time to get it licensed indicates they're fairly confident they'll meet that timeline?
Also they're contracted by nasa to do their first launch in september and this lines up with that.

most of your pessimist kin said spacex was a fraud scam company and wouldn't survive its first decade. they then went on to predict falcon 9 reuse would never work out, crew dragon would fail, etc. i'm not going to bet on them being right about spacex.

NASA lied, again!

>The current solar cycle is bigger than predicted, and apparently John Clark of NASA has sent an email stating that the Hubble Space Telescope might only last another 18 months to 2 years without a reboot. This shocked the #OPAG2024

>throosters fucked
>what if stayliner has to stay?
Ok but for real, what happens if there is a stricken spacecraft docked to the ISS that is unable to perform a controlled departure from the station? Do they give it a toss with the canadarm like that battery pack? Leave it there as a storage closet? No way the can fix it with an EVA, right? Surely NASA has a contingency plan for this.

>>16230851
They have top men working on this.
TOP men.

>>16230851
they could probably tug it out of orbit with a progress or cygnus or something.

>>16230851
They'll probably figure out a way to deorbit it to free a docking port for future crew dragons missions

>>16230851
>Do they give it a toss with the canadarm like that battery pack?
That would depend on if it has an attachment point that the arm can latch onto. I do not think that it does

>Leave it there as a storage closet?
They'd have to for the short term. It can't leave under its own or any other power and the station tends to find a way to make use of any available volume. The Bigelow test module ended up as a generic storage space once it defaulted over to NASA control.

The really big issue would be that for as long as it's blocking one of the two docking ports on the American segment you can't have Crew and Cargo Dragons docked at the same time. The people in charge of scheduling crew rotations and resupply are going to be boldly discovering new levels of Hell.

>Surely NASA has a contingency plan for this
For something as bad as this? Probably not. The best they can realistically do is pray extra hard that it doesn't happen.

>>16230776
>replying to bait from last thread

>>16230875
>For something as bad as this?
they used to have contingencies for everything during apollo. LM ascent engine failure, a crash, massive CME, everything. Now they dont even consider that some shit from boeing might get stuck on their station? sad times.

>>16230875
They 100% have a contingency for this. They’re not going to tell you what it is until they’re for ed to implement it because they don’t want to spread FUD

>>16230875
>attachment point
I thought there was, but if not that seems like something that could be sent up and attached via EVA
>for something as bad as this
It's not great but come on lol "What if space ship gets stuck" seems like a pretty basic question to ask during your risk assessment and contingency planning meetings.

>>16230851
just abandon the ISS, its near the end of its life anyway

Starlink launch does nothing for me anymore

>>16230913
One absurdly large one.

>>16230912
yeah besides how it makes more and more money every month haha

>>16230913
Because it was a requirement back then, the N1 was spec'ed out as a ballistic missile in addition to a launch vehicle. The 1962 version had a 75 ton payload capacity to LEO and was expected to carry enough warheads to be able to annihilate the United States in a single launch.

You de-orbit the thing by uncoupling it and use its thrusters to slow it until it falls below escape velocity and then drop it in the fucking ocean, what else.

>>16230781
>might
Doing a lot of heavy lifting. It's still at 512 km.

>>16230798
HWO won't launch until the early 2040's, and that's assuming no major delays.

>>16230965
>unable to perform a controlled departure
>uncoupling it and use its thrusters
I think you might be the retard here

>>16230965
the hypothetical is “what happens if the thrusters are broken” though

>>16230970
it might be ok for unmanned flight...maybe they wont risk them crapping out when people are on board? they'll probably test the thing and decide if it can be trusted not to wind up going where it shouldn't

>>16230965
>You de-orbit the thing by uncoupling it

When does SpaceX get panzers?

why does the rest of the industry fail to try?

>>16230970
It has some thrusters left, faggot. It's just that they might not be in any shape to safely return astronauts. Keep up, tard.

latest starlink hitpiece: megaconstellations DESTROY the ozone layer. shut them down NOW!

>Satellites that make up megaconstellations like Starlink has lifespan of a few years, before they reenter Earth's atmosphere and need to be replaced.
>Deorbiting satellites release small particles of aluminium oxide, which catalyzes destruction of ozone molecules - 'catalyze' means the aluminium oxide is not consumed in the reaction, and it can go on to destroy more ozone molecules, presumably similar to CFCs.
>Most aluminium oxide particles form in the mesosphere (50-85 km), and takes up to 30 years to drift down to stratosphere, where most ozone is located at.

>>16230995

Its Magian FUD to keep us in their precious cave

>>16230988
As >>16230972 suggested, my premise is that the spacecraft is dead in the water, unable to maneuver in any sort of useful or safe way. Not saying stayliner is in that condition currently.

>>16230924
26 tons could apparently get you 100megatons of nuke. Starship could probably haul the 10gigaton monstrosity edward teller proposed with project sundial straight to any commie within the atmosphere all at once. Could also just blow it up where it stands and not worry about the flying part tho

How financially viable would a Hubble-equivalent private space telescope be?
I can't find any solid data on what it costs to get time on one of the big telescopes, either space or ground. Do research teams even "pay" for that with grant money or do they just submit proposals and get assigned priority appropriately?
Between straight-up renting time on the thing and employing an office full of grant proposal writers to vacuum up government and institution money, what might the ROI look like on a project like that? I bet you could build and run a better version of that thing for so much cheaper without the usual government bloat.

>>16230989
Steel Link is the future.

Steps to Making starship work:
>Make it 18m wide
>Add white structural paint to protect the steel

>>16231020
Honestly the FAA shouldn't have proclaimed test #3 a mishap, either. Good that they're seeing sense now.
The only one which required government involvement was #1 (because of the launchpad) and even that was a Texas problem.

>>16230851
Chuck the fucker retrograde, either with Canadarm like you said or send some astronauts out there to give 'er a heave. Once it's far enough away, use whatever control authority is has left, if any, to slow down even more so its orbit decays sooner.

I hate to be the devil’s advocate fag but
I know these types of dudes. Yes it is innocuous humor. But at a certain point it gets annoying/weird, especially if you know “engineer personality” people. I don’t think it’s outlandish to think that Musk (as much as I bend the knee and worship his autism for progressing us 50+ yrs forward in spaceflight) is probably letting a ton of weird, awkward autism slide at the senior-level; resulting in very very strange interactions at his companies. I hate to say it but doing shit like having IVF children with a subordinate is VERY fucking weird. Making penis jokes when you’re a hyper-smart but hyper-awkward twink when there are smart women in the room adjoining you at the white board is weird.

reminder what berger said 5 days ago:
>The microscopic structural cracks are located inside the small PrK module on the Russian segment of the space station, which lies between a Progress spacecraft airlock and the Zvezda module. After the leak rate doubled early this year during a two-week period, the Russians experimented with keeping the hatch leading to the PrK module closed intermittently and performed other investigations. But none of these measures taken during the spring worked.
>the Russian leaks are now classified as a "5" both in terms of high likelihood and high consequence. Their potential for "catastrophic failure" is discussed in meetings.

>>16231208
This is it, the catastrophic depressurization event.

>>16231217
We're not seeing a mass evac of the station it's probably not a hull breach. There was an American spacewalk coming up that would have involved Crew-8 commander Matthew Dominick, so that could be the commander that was mentioned. The audio we got was a SpaceX flight surgeon and there was mention of "post splashdown," so I think the most likely read of the very limited info we have is that there was a incident in the pre-walk prep and Endeavour might be getting ready for an emergency return to Earth.

what if they're just talking about the procedure for each specific crew member after an emergency splashdown rather than saying that the commander specifically is in trouble?

full transcript of the audio
https://x.com/airplaneian/status/1801032577773666428

>>16231247
>>16231248
Read the description, it has nothing to do with the iss

>>16231248
kek.

>>16231252
Yeah I just realized kek

>>16231250
They definitely aren't. Check the >>16231251 transcript. I could believe this being training if it wasn't for the fact that she ends the call by telling them how to contact a hospital in Spain.

look at him go

>>16231251
Here is a full transcript of the radio traffic in question from the NASA ISS live stream:

So if we could get a commander back in his suit, get it sealed and step into procedure 5.180 for suited hyperbaric treatment, section three for oxygen post-splashdown, that would be my recommendation. How copy?

Copy. Understand that this is a best effort treatment, and so whatever you can do is going to be better than doing nothing. And just as an FYI, prior to sealing, closing the visor and pressurizing the suit, I would like you to check his pulse one more time. How copy?

Correct, yes. That would be, actually, Sif [sp?], you're on this call. How much oxygen do we have remaining in minutes?

Perfect, so yes, then I would like you to have 100% O2 flowing via mask while you get the suit on. Prior to closing the visor and pressurizing, I'd like you to do a pulse check one more time, and then step into 5.180, section three.

Is there a way that the mask can be attached? So is there a way that we could get the suit over the head, have the visor open, and put the mask at least close to his face while you finish sealing up the suit, or is that not feasible?

Copy. Copy.

>>16231249
Kinda sounds like that, or something related to the preparation. Little more than speculation at this point though.

>>16231258
Well, I think at this point, because the hypobaric exposure is the big problem, and given his exam, I am concerned that there are some severe DCS hits, and so I would recommend trying to get him in the suit as soon as possible, and giving oxygen as best as able during that process, but the best thing would be to get him in the suit ASAP.

Thank you. Just as a FYI for you, I am still about one hour out from MCC-X. Unfortunately, we will need to keep doing the phone situation until I am able to be there. I am currently stuck in traffic.

While we don't have other flight surgeons on call, while I am stuck in traffic, I can reach out to see if there's anyone who can get there sooner than one hour. That being said, there really isn't anything we could do in person that we can't do over the phone at this point. Unfortunately, the prognosis for Commander is relatively tenuous, I'll say, at this point, to keep it generic.

One thing, I don't know if you got this message before, but I did find a, through Dan, I did find a hospital in Spain that has critical care facilities and hyperbaric treatment facilities. Would you like me to give you that hospital and their phone number again?

Okay, so that is San Carlos, S-A-N-C-A-R-L-O-S, in San Fernando, spelled the normal way, and that's in the province of Cadiz, C-A-D-I-Z, in Spain. And that phone number is country code XXXXX . Again, that number is country code XXXXX. How copy?

Copy. In the meantime, I will continue my trek in. Otherwise, I will see if a flight surgeon can be there sooner, and then you are free to call me with any updates or any changes. If the crew do get suited and start the treatment and they make a call down, I would request to be updated at that point. Thank you very much. Anything else I can do for you, Sif? Thank you, bye.

>>16231095
what do you think the talks with Argentina are for?

I'm worried guys.

>>16231125
Every window is a launch window if you have enough Delta-V

I lean towards it being the crew 8 commander. The Russians would have their own flight doctor on call.

>>16231265
the chick on the phone said she's the only flight surgeon currently available

>>16231265
russian doctor got conscripted, that's why they are using a doctor in spain

>>16231258
>>16231261

Not good.
I've seen this happen, most likely at a lower level than what happened, but that is bad. The next several weeks will be interesting for spaceflight.

another fifty billion dollars down the drain

>>16231265
Crew 8 commander has/had a spacewalk in a few hours from now, he would have likely been in the middle of decompression to prepare for the walk.

>>16231267
kek

Nothing happened, it was a drill

>post splash down
Yeah, it definitely is the crew 8 commander. Starliner can't splash down and Soyuz would be an odd as shit choice to specify splash down.

>>16231270
how can you get "multiple dps hits" during eva prep though?

>>16231216
it would be so funny if someone hit this with an anti-satellite missile while it was full of chinese "people"

>>16231270
note, the pre-spacewalk procedure includes being in the special airlock area, so maybe it wasn't a pure O2 breathing system failure but a issue with the final airlock door?

>>16231273
maybe they dont trust soyuz or starliner to return the injured commander safely

>>16231274
it's suppose to be dcs aka decompression sickness

>>16231273
Read, nigga, read:
>So if we could get a commander back in his suit, get it sealed and step into procedure 5.180 for suited hyperbaric treatment, section three for oxygen post-splashdown

Any live maps of current ISS location and trajectory? Maybe the spain hospital is the closest to their current possible deorbit burns?

>>16231279
somebody find procedure 5.180

>>16231279
That really doesn't give the enough context for what "post-splashdown" means here.

>>16231280
the SpaceX dragon recovery ship is rather specialized. I'm really not sure some random boat in Spain can bring it onboard etc?

>>16231280
the orbit's nowhere near passing close to spain right now. it's gonna be hours away if that's what they're doing.

>>16231280
They about 8 hours away from a landing near Spain. It's more likely that the Cadiz hospital was brought up as an option for a telehealth consult since they're hyperbaric specialists

>>16231283
What, they can't open it on the water?

>>16231035
To state the obvious, your financial viability would hinge on cutting up costs and then minimizing your operating costs. Can't say much about the business case though.
>cutting up front costs
The obvious thing to do would be to trade manufacturing complexity for mass where it makes sense and take advantage of COTS parts as much as possible. For launch costs, you'd bank on starship's supposed low $/kg to orbit, but depending on dimensions though you may be able to get by with a Falcon 9 in some configuration.
>cut operating costs
Big difference between now and the early 90s is the capability and power draw requirement vs size and cost of computers. You could have a lot of on board processing done to minimize/optimize data that needs to be downloaded through the DSN, or even better yet, use starlink some how instead of the DSN. Once your data is on the ground, hopefully your private enterprise would be much leaner and more efficient with its manpower than a public entity to keep salary costs down.
>business case
There's only so many university astronomy departments with only so much budget to spend on imagery. If that adds up to be more than what you manage to get your cost down to, then sure, viable, but probably not

>>16231280
Wouldn't just using the Soyuz or Starliner be better at this point? You would want to land on land in an emergency rather than waiting for somebody to pick you up from the ocean.

>>16231287
it's not that they can't, but ultimately, the dragon capsule is more valuable than an astronauts life

>>16231283
fly a coastguard helicopter out there

>>16231283
I would imagine they'd prefer to bring him back to NASAs flight surgeons anyways.

>>16231284
>>16231286
Yeah, nevermind
If they wanted to do an emergency deorbit they'll be quite close to the west coast in the next orbit

>Any live maps of current ISS location and trajectory? Maybe the spain hospital is the closest to their current possible deorbit burns?

From what I've been hearing, if Dragon makes an emergency undocking soon, they will be splashing down by Spain.

I feel like of them got depressurized, and they are going to do an emergency landing to try and save him. I've seen divers who come up too quickly puff up from the rapid drop in pressure, but this is a whole different environment. I think we may have our first death in space.

You could use starships to get them out to LaGrange points and do parallax studies too. What I'd really like to see would be some of the Key Hole EO sats hubble was based off of around mars

>>16231295
back to our regularly scheduled programming

>>16231296
>I think we may have our first death in space.
The first American death you mean?

>>16231289
You need to leave on the ship you arrived on. A Russian Sokol suit wouldn't be able to hook up to the life support systems on Dragon or Starliner. You could just pile everyone in without suits but NASA would only go for that if the station suffered a major breach, and the Commander needs to be suited up and linked into an oxygen source for the current treatment to work.

>>16231292
>fly a coastguard helicopter out there
Not a bad idea actually. Get a rigger to lash it up and they can fly it to land.

>>16231295
Nothing burger. Nothing ever happens.

>>16231295
why would they wake up a doctor half way around the world at 2am for a sim? the janitor could play that role

>>16231306

Just because we like spaceflight doesn't mean we're well adjusted

>>16231300
>The first American death you mean?
Fair.
I meant on the ISS specifically.
Unless I'm just an idiot and a Russian died on the ISS?

Do we have a second confirmation of sim?
The line
>Understand that this is a best effort treatment, and so whatever you can do is going to be better than doing nothing.
had me really worried.

>>16231284
Might just be the only place that has facilities to treat that kind of decompression sickness, or maybe they want to get the experts there to assist remotely.
You'd think NASA would have prepared for this sort of thing though, at least to the degree of having some names and numbers ready.

>>16231321
It was a Salyut station and all three dudes died when they went to undock, something fucked up with the docking ring and pried open their sealed tin can as it departed. The whole thing was on autopilot so Soyuz delivered their blue corpses safely to the landing site on the ground.

>>16231329

>>16231333
they undocked from salyut fine. it was when they jettisoned the orbital module before reentry that the reentry module decompressed.

>>16231337
A pressure regulation valve opened well ahead of schedule and depressurized the capsule prior to reentry. This was back when Soyuz crews were even more mass-constrained than they are now, so there wasn't a budget (or room) for them to wear pressure suits as a part of normal operations.

>>16231341

Russian translation, back into English:
>There were no emergency situations aboard the International Space Station.
>At approximately 5:28 p.m. On the CDT, the sound was broadcast live by NASA over a simulated audio link on the ground, indicating that the crew member was experiencing effects associated with decompression sickness (DCS). This audio was inadvertently garbled from an ongoing simulation in which crew and ground crews train for various scenarios in space, and does not relate to a real emergency.
>The crew members of the International Space Station were sleeping at that time.
>Everyone remains healthy and safe, and tomorrow's spacewalk will begin at 8 a.m. ET as planned.

There's no money to be made

>>16231436
Who cares about nsf. I'm talking about putting some big heavy cheap optical scopes into space. A whole bunch for economies of scale. You charge by the hour for observations or by the photo for images. The client base would be pretty broad. Everything from space agencies to universities, museums, even science clubs I suppose depending on the price.

>>16231435
Not bad, but the context lost is that SpaceX pioneered it 10 years prior to Rocketlab's first launch.

>>16231443
The customers is the NSF. Everything from space agencies, universities, museums, science clubs go to NSF for funding/research. Thats where the customer is.

electron is cool but I fear neutron may be dead on arrival
I wonder how much a neutron launch will cost vs going on a SS in a shared payload

>>16231451
I kinda like Neutron because it's weird and launching from Wallops, but I have to agree. It has an uphill battle even without Starship. Pretty sure the number tossed around for Neutron was $50-55M

>>16231450
You're still not getting your money back, let alone making any profit on a project like that even if you charge the crap out of scientists for observation time
Only someone with Musk's net worth and a really good heart would ever fund something like that

>>16231451
Starship will put everything else out of business. The only survivors will be those kept alive by governments for national security reasons.

>>16231451
I've seen Neutron described as "the Antares of reusable rockets" and I can't say that doesn't sound accurate. At this rate Rocket Lab is going to get lapped in engine development by Stoke and Relativity.

That said, I could potentially see Neutron launches from my house, so I feel compelled to be supportive.

>>16231455
Charge 500$ an hour for 24 hours for 1 year and that's $4 million. It would take 1 year to pay off the starship launch at that price assuming you fully book the telescope

>>16231460
Sure, easy to cover the launch costs, what about the other >2 billion your cool telescope will cost?

>>16231452
I think neutron is almost fully reusable after light refurbishment so that price per launch should come down a lot
it'll be good for customers who want an affordable rocket that can take them almost directly to their target orbit as they won't have to share the launch with other customers which would be the case with SS

>>16231461
Leave it up there for 25 years.

>>16231275
ok

>>16231469
Ok, you got 100 million now, just 1.9 billion to go

>>16231461
Don't make it out of expensive materials then? Starship allows the use of cheap n heavy materials like glass over beryllium. you also don't need complex mechanisms. I bet you could get the cost down a fair amount and make a Hubble successor pretty easily. There would be tradeoffs In capability but that's something you would discuss with the scientific community at large to address their needs.
If you make the whole thing automated it could run 24/7 on a schedule without management.

>>16231469
Also this. If you leave it up there as long as Hubble has been up then you get your money back and make a profit.

>>16231480
Yeah this. Go the RFA route and use cheap mass manufactured parts. The expensive stuff is the mirrors and the sensor equipment but even those will be less expensive because they aren't mass constrained due to starships huge payload mass

>>16231461
Do a joint DoD/private sector project. Harvard alone has an endowment of over 50 billion dollars. Split the cost of the telescope 50/50. Pitch it as a NEO detector, and then have all of the different Unis who would want to use it kick in a percent of the cost of the development in order to gain access to the data and time on the scope. Hell, if you want to make an it an international project, then expand it to include different organizations and unis that aren't American. 2 billion sounds like a lot, but if the DoD covers half, that's 1, and if the rest kick in 50 million each (shit they could find in their sofas) then you would easily be able to take care of the construction of the telescope.

Europe has their own NSF version and its even more unlikely to get any private customer there because its more of a communist state there. Atleast in the US, theres a chance in the near future

You still need a good mirror. Those are always expensive at hubble scales, even for dirtside telescopes that don't need to worry about mass constraints.

Honestly, your best bet is probably going to be some kind of big interferometry constellation. Pick the best optics you can and then buy them in bulk. Operating a flock of a few dozen networked satellites will let you get away from bespoke problems and make it easier to continuously maintain and upgrade they system.

>>16231485
Why don't they do it then? The launch cost is negligible compared to the telescope itself
Falcon Heavy is right there and could easily launch something larger and more capable than hubble, even without tricky folding mirrors

>>16231491
Explain where the $2b figure comes from. You aren't inventing anything, you don't have mass constraints, and the launch could be in the single millions

we really need better exoplanet telescopes,
our current primitive methods of transit photometry and radial velocity(star wobble) just isn't cutting it with what we have up there right now
we are missing out on at least 80% of smaller earth/mars sized like planets currently

>>16231493
>optical interferometry
That doesn't exist the way you think it does yet

>>16231495
Because they are gay. And they do do it. The University of Arizona by themselves have built several very large telescopes. The Steward Observatory Lab at Arizona builds the mirrors for Magellan.

>>16231496
Hubble today would cost 3.6bil with inflation, you're not developing a similarly capable telescope for less than 2, anything worse than the hubble is just not worth launching at all

>>16231496
He probably got the figure from Magellan because that project cost 2 billion.

>>16231479
Unironically earth imaging is one way to break into the market and get positive cash flow before launching Megane 1 into orbit as a proof of concept to show a company can operate a space telescope commercially
>>16231485
>Pitch it as a neo detector
One of its potential capabilities I like this it won't cost 2 bil though. Also we are talking about more than one telescope. I'm talking about like a dozen so you get economies of scale on the expensive parts. Imagine 12 bigger than Hubble optical space telescopes operating in orbit. You could do so much with that. Would need other revenue streams as well but that's all part of the business of commercial space
>>16231491
It's not gonna cost 2billion dude.
>>16231493
>Expensive mirror
Yeah I'm aware but the mirror isn't going to cost 2 billion and even if it's several hundred thousand dollars or even a million per mirror that will be the bulk of the cost of the telescope and the rest can be done a lot cheaper than Hubble.

>>16231500
Never underestimate engineers and their creative ways to cut costs. If you aren't paying the premium aerospace prices for parts you can get away with a much cheaper telescope. Also again, Hubble was mass constrained. This telescope has over 100tons to work with. There is basically no mass constraint here. No need for lightweight composite or aluminum. You can use steel and other suitably strong and heavy parts.

>>16231502
The problem with mirrors is time. One of the main reasons why they do segmented mirrors in the first place is because they take less time to grind and polish than huge single mirrors do. Going back to Magellan, it took them something like 13 years to grind and polish all of the mirrors. There is probably a way to cheat this with laminates, but what the fuck do I know?

>>16231504
Problem's not mass, it's assembling the damn thing and making the mirror, this takes time, expertise, and by extension, money

>>16231505
>Cheat this with laminates
Finding a way to make a cheaper primary mirror would be a huge breakthrough and something worth funding so...

You could use nonstandard shit like water or some other liquid that forms into a mirror. Or have some super tiny, easily mass manufactured polished tiles like pic related though getting it to focus might be a problem.

>>16231500
Hubble was engineered around constraints that Starship eliminates. Add in advances in computers over the last 35 years and $2b is an absurd number

>>16231323

>>16231497
nobody gives a fuck about finding good exoplanets since interstellar travel is a very long ways off still

>>16231478
>beryllium is cheap and heavy

What the fuck are you smoking? Beryllium is extremely lightweight and extremely expensive

>>16231372
Why is microgravity in quotes?

>>16231513
>a high quality camera
>some mirrors
>sattelite bus
They might as well make a telescope as a mass simulator for next flight test

>why is elon obsessed with human population numbers?
Because the people that actually build society and drag the rest of the morons into the future are a tiny %.
Less people = less autistic engineers
