Four stamps from Bulgaria, Switzerland, and the US. 1981-2009

>>14979053
he looks like the type of men you'd find in a bar here

>>14979053
The Swiss one is a pre-printed Shuttle stamp, exclusive to the postcard it belongs to

>>14979055
Both US stamps are shuttle stamps from the same 1981 "Benefitting mankind" series. I presume that both are meant to be Columbia.

As a sidenote I'll add that today is the 41st anniversary of STS-2's launch, also with Columbia.

>>14979437
The Chinese say that they're building copies of everything, especially when those things are the best or the biggest, but the only projects that Beijing ever decides to fund are the things that they have a real clear need for. They don't have orbiters the size of Buran or Columbia that need hauling around and they're perfectly capable of shipping payloads as large as their new station modules to Wenchang by boat. If the Soviets could have moved large things around by water as easily as the Chinese can the Mriya probably never have existed in the first place.

Seems like a relatively simple, if very large scale structure to put together. I'd hope to see more space stations like this as Starship spins up to LEO operations. At some point someone is going to have to figure out how to build large structures, do space welding quickly, reliably, and safely. Might as well start with depots and staging areas.

1051 launched Demo-1. It launched 575 starlink satellites, along with several other commercial sats.
1051 was a real achievement. It alone exceeded the upmass capability of other rocket families, launch companies, and even entire nations during the time of its service. It showed us a glimpse of the potential of rocket reuse.
RIP, 1051, you did a good job.

The NASA Astronaut Corps have a hard requirement for human-rating a rocket: someone riding on it can manually abort the launch safely at any time

No abort, no rating.

>>14979818
how did the shuttle slip by that requirement? was it brought in post-challenger?

>>14979818
Luckily that rating will be irrelevant soon

>>14979818
>someone riding on it can manually abort the launch safely at any time

>>14979834
>that launch tower
what a mess

>>14979838
It seriously is, outside of that early hiccup with one of the RS-25s and the inherent problems of the batteries in the ICPS being designed by chimps and the SRBs inherently rotting away in the elements and having to be replaced if the schedule slips to much, every other problem has been because the launch tower is just absolutely decrepit.

>>14979835
Nobody in NASA was ever pretending the Shuttle meets the requirement posted above.
It's simply not a hard requirement as stated then.

>>14979843
Pretty much everything about the Shuttle was given the "yeah it's probably good enough, don't worry about it and don't ask questions" greenlight

>>14979840
This reads like cope. There is neither a problem with the batteries nor with the SRBs

>>14979532
Are they okay?

>>14979718
yes, he would

>>14979588
it occurs to me that if the lightest air such as helium can get you into the stratasphere- then why not construct a volume in the vacuum of space itself- containing NO air at all, it will not pop like a air balloon eventually does and would be able to sit on the very top of the earths atmosphere and not worry about orbital decay. Generally i think this would be an anchor point for an elevator and a launch site that can skip out the need to push through the atmosphere- perhaps too awkard to doc with a mid flight shuttle given it will stull be on the atmosphere and you have to fly faster the closer you get to earth to maintain orbit- but it could just chuck out the supplies and be caught by the shuttle. would make for an amazing tourist attraction too- make it nice and big, dounut shaped would be stable i think.

>>14979753
>There will be no public outcry because this will not be paid any attention.
I hate to say it, but there will be no outcry because it will not happen. Starship is a dead end, SpaceX has the capacity to build a moon rocket but not through Elon's silver meme rocket. Falcon and Falcon Heavy and iterations are the way to go. SpceX makes damn fine rockets -- Starship is a shiny toy to keep Musk out of the real work so engineers can get shit done.

>>14979868
30 years ago, your words would make sense. But the world has changed.

>>14979869
Yeah, safe in the arms of Jesus.

>>14979874
Then why did the company bet starlink working on starship and why did the company invest billions of dollars and most of the R&D team on the rocket?

>>14979874
Keep shilling tranny. You're getting ever more delusional

>>14979874
Does this take the cake as one of the dumbest sfg posts of all time? I think it does.

>>14979872
>then why not construct a volume in the vacuum of space itself- containing NO air at all?

Helium/hydrogen/hot air balloons inflate by being under equal or greater pressure than the surrounding air. Hard to build up a lot of pressure with vacuum.

>>14979879
They made a mistake because the boss insists? Or they are not serious about planning to rely on Starship? Either seems possible.

>>14979881
>Keep shilling tranny.
>>14979882
>Does this take the cake as one of the dumbest sfg posts of all time?
Frankly I could not care less what you guys say -- It is absolutely clear that Falcon and Falcon Heavy are very fucking good rockets, I don't care what you haters say.

>>14979874

>>14979903
I don't think the anti collision measures in airliners would work either in such a scenario where you're close together from the get go and would need an alert within a few seconds.
You could have that though with just GPS and higher rate state vector broadcasts.

>>14980244
>With the Democrats taking the Senate

Democrats already had the Senate.

>>14980244
The biggest difference for SpaceX is they'll lose government contracts if they keep trying to stop unionization. If they are willing to take care of the staff that made them the dominant launch provider I don't see any issues.

>>14980287
But now the dems have a clear senate majority and can't be blocked by one senator. With the house the dems can pass or block any spending legislation they want now. The only question is whether old space or new space will benefit.

>>14980302
No one will benefit.

>>14980302
If the Dems get control of the government you'll have a lot worse to worry about than space funding changes. Forget about getting Mankind to space at all.

>>14980302
NASA is always a popular subject regardless of political parties. Space politics are about contracts and jobs in the senator’s states, not about right or left politics. You should know this by now

>>14980302
Much bigger news for space is Shelby is gone, that one man held back space development 30 years.

Now that the Chinese seem comfortable with non-hypergolic engines and can produce the YF-100 in reasonable quantities they're talking about using the LM-5B to launch their own megaconstellation. We're going to get to play core stage roulette once a month in not too long.

Question, SFG:
Why was it so hard to break the sound barrier in the first place? Was it all mental?

>>14980331
Propellers make it very difficult because they don't do much besides spin the air around. You need jet or rocket power to do it reliably.

>>14980331
Supersonic speed are near impossible with propellers, the only plane to do so was the experimental XF-84H Thunderscreech in the 50's

>>14980338
Is that that crazy fucking plane whose propellers would also break the sound barrier as they spun? And it was loud as fuck and sounded insane?

>>14980340
Yes.

>>14980341
Kino

OK sfg bros, we want to resolve an earth-size exoplanet at 1 megapixel resolution. What will happen first:
1) batch sending solar sail / laser-propelled spacecraft to 600au to utilize solar gravitational lensing
OR
2) visible light interferometry via quantum computer networks and telescopes on/orbiting Earth
?

>>14980345
Fusion powered 600AU non-flyby.

>>14980340
The noise is the least of its issues

>Unlike standard propellers that turn at subsonic speeds, the outer 24–30 inches (61–76 cm) of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. The shock wave was actually powerful enough to knock a man down; an unfortunate crew chief who was inside a nearby C-47 was severely incapacitated during a 30-minute ground run. Coupled with the already considerable noise from the subsonic aspect of the propeller and the T40's dual turbine sections, the aircraft was notorious for inducing severe nausea and headaches among ground crews. In one report, a Republic engineer suffered a seizure after close range exposure to the shock waves emanating from a powered-up XF-84H.

>>14980349
>producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards.
I'm having trouble imagining what this even looks like.

>>14980349
7 hours of total flight time before being grounded forever. the pilot refused to get back in the cockpit

>>14980350
Imagine DBZ style continual air distortions radiating out from the propeller tips. The plane went supersaiyan.

I'd say artillery shells do it better and cheaper
Just make a dummy shell with holes at the front that creates a Stuka-esque sound or screech, and fire them with your artillery

>>14980365

anyone in direct earshot would be incapacitated and/or seizing. it's perfect for torturing civilians. so based

You'd have to be a few hundred meters from the props to get the ill side effects of pressure sickness, and even then you would be unaffected if it just strafed by at mach 1.
Ground crews only experienced sickness or nausea after a few minutes of a 30-minute test

>>14980379
Just make it faster. Spin the blades at mach 3 or something.

>>14980350
I guess it depends on the humidity. It could be like the vapor cone around a vehicle, or it could be a shimmering of the light being distorted by the rapidly changing air density, like you can see in schlieren imaging of supersonic aircraft or, rarely, rocket exhaust noise waves.

>>14980391
Use an Energia configuration for the Space Shuttle.

>>14980393
That's literally what SLS is.

>>14980399
is it possible to add a side-mounted space plane to SLS?

>>14980331
If I remember right there were a few things they had to figure out in the late 40s:
It was hard as hell just to build wind tunnels that could simulate the transonic regime

Then they had to figure out how to keep a jet engine from going out when the intake was admitting supersonic air

Then it was transonic instability (they figured out the area rule pretty quick)

And THEN they had to figure out the inertial coupling problem

After all that some poor sap shot himself down by flying into his terminal-velocity cannon bullets

>>14980400
Probably, but that reintroduces the Columbia death foam problem. It'd be better to make an HL42 sized DreamChonker or that Lockheed X-Wing Mars shuttle and put it on top of a Block 2.

>>14980399
SLS is inferior to Energia. Energia also has flown more than SLS.

Pooping in space just spunds like it would be fun and feel amazing. I been reading a lot of how astronauts get "constipated" but that's not a bad thing really. It just means their body is able to store much more poop than normal since gravity isnt pulling the poop down. Such that when astronauts eventually do have to poop, it's like this immense long strand of expansive spongy poop, unlike anything you could excrete on Earth. Imagine what that would feel like

>>14980407
Imagine transferring from a deep transit ship to a spingrav station and suddenly having a week's worth of poop feeling gravity's call. You'd want to keep the parts of the spin wheel next to the elevators well supplied with toilets.

>>14980405
That's what you get for using death sticks instead of proper liquid boosters.

>>14980407
It'll feel like fingering your asshole because that is how you fish all the floating poo poo out from your starfish.

>>14980412

Its gonna be fucking KINO

I doubt the footage will look much better than what we already have.

>>14980504
It'll look worse.

>>14980470
NASA will ask for 5 billion dollars to develop 4k camera

>>14980470

We lost the tech

>>14980523
Boing was given 82 bil USD and still no 4k cameras. Welcome to oldspace.

>>14980470
best I can do is 720p youtube compressed screencaps

>>14980504
The new footage will be souless. 4k digital images are too sterile. It needs to be shot on real film that gets properly developed.

Found on Twitter. Roman's 18 4k^2 infrared detectors for the Wide Field Instrument. Looking pretty. For defence JWST uses smaller 2k detectors, of which NIRCam has 10.

>>14980536
By 2K you mean resolution, like in cameras?

>>14980539
Yes, 2048 pixels along one side. ~4 megapixels in consumer camera units.

>>14980504
Unfortunately I agree. They will literally not produce footage better than in your picture. They were better at it 50 years ago

>>14980738
Technically yes, but it's just too sterile. It's like when you look at an older ever so slightly grainy movie and compare it modern movies. All the "warmth" of the colours are gone and everything is too fucking perfect looking.

I really don't know how explain it without sounding like a buzzword spouting retard, but I much rather footage of rocket launches and the likes looked like pic related.

>>14980784
Pretty sure it's possible to make a filter, slap it on modern pics and get this effect (it would be the most soulless thing, tho)

>>14979581
looks kinda like 1980s freedom designs

>>14980864
I'm sure that was the point

Is hydrogen slowly being retired as rocket fuel? I think Vulcan and New Glenn are the only upcoming rockets that still use hydrolox, mainly because they're oldspace.

>>14980884
ariane 6

>>14980864

>>14980884
No, if anything it is becoming even more common since you see a demand for high energy upper stages. Of the current and upcoming heavy/super heavy lift rockets only Space X's rockets and Relativity don't have/plan on having a hydrogen upper stage.

>>14980894
And Proton I guess

>>14980894
But I'm not talking only about heavy+ lifters. It seems like only the veterans are choosing the hydrolox, because they have experience and for newcomers, it's too expensive.

>>14980907
No shit oldspace uses hydromeme and nobody else, it has to do with the history of rocket engine development. RP1 as a first stage makes more sense but since hydromeme was developed in the USA because they couldn't risk RnD costs on oxygen rich staged combustion.
Also hydromeme is garbage as a first stage, RP1 is king and more economical.

>>14980918
mark my words, BE-4 is going to be way more of a bitch for reusability than BO/ULA expect. And at the end of the day AR1 will be vindicated as the better option that was never chosen
Reminder that the RD-180 was designed with reusability in mind

>>14980907
Aside from how complicated it is to work with using hydrolox has diminishing returns the smaller the rocket is. You rather have dense fuel by point you reach the size of small size launchers.

>>14980907
Hydrolox is more popular than ever so I'm not sure what you're on about. A few small sat launchers not using it because using hydrolox is retarded for them doesn't change that.

For me? It's naphthyl-oxygen.

>>14980402
>some poor sap shot himself down by flying into his terminal-velocity cannon bullets
expand on this pls

>>14981017
For the upper stage, you mean.
It's called using the right tool for the job, within expectations and budget constraints.
RP-1 is still the better choice for the first stage.

>>14981024
Russia and India especially have had awful luck with cryogenic upper stages and would be way better off just using hypergolics or solids
Expertise is another metric you should factor in

>>14981024
Yeah, no shit. Don't make retarded assumptions of my intent.

>>14981028
What the fuck does that have to do with what I'm saying? Are you even reading the posts or do you just want to flex your pop sci knowledge?

>>14981029
Slow down Mr Egotistical, I'm merely appending your statement so you don't get into useless slapfights (like you are trying now) by flexing poorly researched talking points.
Hydromeme is a word for a reason.

>>14981032
gonna cry?

>>14981032
You are clearly unhinged

>>14981034
Appending my statement? I literally agree it's shit. Doesn't change the fact that its more popular than ever.

Pseudo intellectuals are so embarrassing.

>>14980756
To see how it bends where.

>>14981038
Can you name those numerous examples? There is Ariane 6, SLS, LM9, Vulcan but they're all either oldspace, or government rockets and don't imply increasing popularity.

>>14981038
What's embarrassing is that you are so invested in an argument and yet do not specify crucial data required for productive discussion.
If you don't have a productive response, do not respond- it is already expected you will only lash out while using ambiguous wording like "popular," since you are clearly too narcissistic to clarify within something as broad as that word.

>>14981058
Well that's disingenuous nonsense to not include old space or governmental built rocket. Outside those there are literally only smallsat launchers and SpaceX.
>>14981060
None of what you brought up were crucial data. This discussion was always whether hydrolox is becoming more or less used. Not why it's shit. Stop with this doubling down nonsense and actually read the thread. I assure you most retards here knows RP-1 is a far better for first first and booster stages.

>>14981077
Ofc you still respond, you just can't handle it.
Here's something more your speed then, since you are so blinded (or stupid) that you cannot read the very post you are responding to:
HOW. IS. IT. GETTING. MORE. POPULAR?
There you go, six words. Here are four more:
GIVE. US. THE. PROOF.
Now tell us and stop deflecting, otherwise you are just running damage control. You wanted a slapfight, now answer us damn it, or you are exposed as the fool.

>>14980884
bet they regret committing to Vulcan Centaur and Ariane 6

>>14980926
>mark my words, BE-4 is going to be way more of a bitch for reusability than BO/ULA expect.
ULA doesn't have any expectation on BE-4 reusability

>>14981022
You are constantly producing thrust and cruising at supersonic speed, your bullets exit the gun barrel at your speed plus whatever speed their propellant charges impart. You fire bullets ahead of yourself, they begin to slow down immediately after leaving the barrel due to air resistance, you do not because you are producing constant thrust. The bullets eventually slow to terminal velocity, the speed dictated by the maximum acceleration under 1G gravity minus air resistance losses, you collide with the bullets because you are now moving much faster than they are.

>>14979243
>The Chinese Dream (tm)
Looks staged, if you are US you can do the same.
But maybe it will be regarded as old fashioned.

>>14981084
>still doubling down this hard
Pathetic.

More nations and rockets than ever before will fly rockets using hydrolox within the next 5-10 years. That's why, I already said it. Rocket development is not exclusive to the private sector which you for some reason believe. And even if I think the private sector is doing a much better job the majority of the world's developing rockets come from old space and governmental institutions.

The US, India, Japan, China, ESA and even fucking Russia will/plan on using it in the next 5 years.

On top of my head rockets that will use at least one hydrolox stage that will fly by then are H2, H3, Angara 5 KLVH, Long March 5, Long March 5B, Vulcan, Ariane 6, GSLV mk2, GSLV mk3 and New Glenn. And I probably missed a bunch.

Never has there been so many rockets using hydrolox.

Yes, hydrolox is a meme. Too bad most rocket development is performed by memers.

>>14981104
who was the guy that did that?

>>14981077
You're disingenuous for ignoring smallsat launchers in the first place. The majority of new projects are using either kerolox or methalox. SpaceX, Rocket Lab, Relativity, Firefly, ABL or RFA. Those companies are setting new trends, not NASA or ULA. Meanwhile oldspace is replacing their old hydrolox vehicles with new hydrolox vehicles. ULA is retiring DIV and Atlas V in favor of Vulcan. NASA is making SLS, based on Shuttle while Ariane 6 is just an updated Ariane 5. This isn't a sign of increased popularity.

>>14981106
>no direct comparison
>reddit spaces
>holier than thou bitchfit
>categorizing countries as singular entities
Just the surface of the issues in your thinking, but you will never change them because you are blinded by emotion, but since I suspect this gish galloping is intentional, I digress into my main point:
By your own logic, if we sort by the "engine development institutions," "use cases," and "engine development" we could have a comprehensive list of whether or not, empirically, "hydrolox is popular." But you are only involved in this conversation for your ego, as I stated several posts ago. You were requested to give even basic evidence but you instead sputter unspecific, thus useless, data.
Lmao. I'm not taking you seriously if you can't even take the time to back your point with evidence, as you are the claimant. I tried to be nice, but you invoked a pointless de-railing egocentic argument without bringing in real numbers. Kill yourself, it would be a net benefit to the spaceflight thread.

>>14981133
The fact that more smallsat launchers are entering and the fact that old space is completely retarded doesn't change the fact that more rockets and more nations than ever before will use hydrolox.

Again, stop being such a sperg and actually read the posts before trying to say irrelevant shit everybody here already knows. Hydrolox is becoming more popular than it has before, which I personally find to be a shit development. Especially for nations like Japan.

>>14981137
>a whole text of damage controlling nonsense
More rockets than ever before will use hydrolox in the upcoming years. That'sa fact. By definition it has become more popular. You completely sperging out and posting irrelevant nonsense when yoj got called out as the pseudo faggot you are won't change this FACT.

>>14981137
Do all pseudo-intellectuals sperg out this hard when they get accused of being one? It felt like I was reading one of those edgy sonic pastas.

>>14981133
What small sat launchers will exist in 5 years lol. SpaceX is now launching once a week till they run out of boosters

>>14981192
HECKING DEDICATED ORBITS

Who the fuck cares what fuel regime is more popular? What is this fucking twitter now, even if we assume that hydrologgs is more popular what the fuck relevance does that have, except that stupidity still exists now as it did say ten years ago, and that stupid people will indeed continue to be stupid?

>>14981192
Unironically none in the US. Rocket Lab and Relativity Space will have moved on to Neutron and Terran R. I don't expect anybody else to survive in any meaningful manner. Might be some in other places like Europe (RFA for an example) since they seem at least 5 years behind in the smallsat trend.

>>14981192
Rideshare is not a replacement for specific orbital parameters required by scientific test satellites, which are the majority of smallsats currently being made

I had a dream that Starship was launching the same day as SLS. It was epic

>>14981230
Why bother if you can just buy a dedicated Neutron launch with return to launch site for a similar price at that point?

>>14980338
I think supersonic prop driven aircraft are more possible than they are usually given credit for. Consider that there are tons of supersonic low bypass turbofan driven aircraft, which generate a not-insignificant portion of their thrust with a fan. We are VERY good at making supersonic blades these days after decades of working with turbofans. We have the benefit of lots of knowledge and tools that the engineers working on the XF-84H didn't have.


Note that I'm not saying supersonic props are in any way practical, just that they aren't impossible.

>>14981243
A dedicated neutron lauch for a cubesat?
Keep in mind that many universities or companies get a certain budget for the satellite and launch, so building a larger satellite is often out of the question to preserve funds for the launch

SLS is still fucking broken jesus christ

>>14981370
I'm saying the total cost to operate a Neutron that returns to launch site would be cheaper than throwing away an entire Electron rocket.

Why put the cubsat on Electron if it cost less to use the Neutron?

>>14981382
NTA but you’d i’m sure a lot of it has to do with the option of a) getting an electron launch in the next ~3 years or b) waiting an undetermined amount of time for neuteon to not only go online but then be free for your launch after going through it’s dedicated, more pertinent payloads first
If you’ve already been given enough funds to build your payload and still afford an electron launch then why sit around for something cheaper

ominous

>>14981416
I'm talking about why there's no point in smallsat launchers relatively soon into the future. Neutron and Electron are just an example dynamic I'm talking about and obviously in the context of both of them being fully operational.

>On Sept. 21, 1956, test pilot Tom Attridge began a shallow dive in his F11F. As he did, he fired two short bursts from the aircraft’s four 20mm cannons, and thought nothing of it – until he got to the end of his dive, and the bursts began to shoot up his aircraft. He started at 20,000 feet and then went into a Mach 1 dive as he fired. He accelerated with afterburner and at 13,000 feet, fired to empty. He continued his dive. but at 7,000 feet, something struck his canopy glass and one of his engine intake lips. The aircraft began to lose power, and Attridge headed back to base to land it.

>But in order to make it back without shattering the canopy, he had to slow down his Tiger to a crawl, and the engine would only produce 78 percent of its normal power. He wouldn’t make it back to base at that rate. Two miles away from the runway, the engine went out completely.

>Attridge didn’t bail out – test pilots are crazy – in the slowed aircraft, he settled into some trees. Despite some injuries, he exited the plane once on the ground and was picked up by a rescue helicopter. The plane, as it turned out, was hit in the windshield, the right intake, and the nose cone by its own rounds. The low pitch of the plane and its trajectory, combined with the trajectory of the bullets and the speed of the Tiger’s descent at half the speed of sound right into the guns’ target area, meant that the plane would easily catch up with its own burst of 20mm fire.

>The pilot shot himself down in about 11 seconds.
