I'm not sure if it actually "shares its design" with KH-11, but has a more indirect connection, e.g.:
https://news.ycombinator.com/item?id=23150092:
> My favorite KH-11/Hubble story is that during the design of the Hubble Space Telescope, NASA originally wanted a 3 meter mirror. However when they began to design and budget the satellite they were quietly told they should reconsider and use a 2.4 meter mirror, as this would be significantly cheaper since they would be able to leverage existed machinery capable of created mirrors of that size and precision. That infrastructure and manufacturing process had already been created a decade earlier for Keyhole.
Perkin-Elmer designed a new null corrector to verify that the mirror was made to spec, but the null corrector was incorrectly assembled (one of the lenses was out by a few mm). They also used the previous null corrector to test, which showed that the mirror was incorrectly ground, but decided that the new null corrector's measurements was correct.
The test equipment is a much smaller part of the cost than developing, building and testing the machines required to actually grind the mirrors to spec in the first place.
but that's an awesome rabbit hole you pointed out!
Why have i never seen these, is it simply that I wasn't looking for them?
One is that Hubble's mirror is not expected to burn up on re-entry and may therefore hit the ground.
How is this managed with similar spy satellites? Presumably the problem is more acute, because not only do you need to avoid killing someone, but you also want to avoid any chance of falling on hostile territory. Are they actively steered into known parts of the ocean? Or does something else happen (one suggestion with Hubble was actually to fire a missile at it just before entry in order to break the mirror in space).
And just because the mirror won't technically completely burn up in reentry doesn't mean it'd leave anything useful for adversaries.
For instance: https://www.thespacereview.com/article/5003/1
That's all fascinating stuff! What are some books that cover the start of the pursuit of those advanced machines? Can I say warfare machinery? Was it the end of WWII and a race to self-protect, was it the start of cold war, establishment of NATO, or a particular administration?
It was kind of a "yeah of course, what do you expect, we don't have this capability?" rhetorical question.
It was known in much the same way Janet flights are known.
Thinking that nasa leadership wouldn't be aware of its existence at all is not accurate, I think, any more than thinking people at certain aerospace contractors didn't know it existed... More like, it was metaphorically over on the other side of a fence that people were not allowed to touch.

There’s plenty of other examples, Hans Mark is the most obvious highest up one. “Leadership at NASA doesn’t know about the NRO” is a hilarious concept to me. Did they forget they own jobs?

Plenty of other similar examples.
How is NASA leadership not supposed to know about the NRO when they worked for the NRO?
That seems unlikely because they'd have been recruiting from the same pool of talent. They'd have been wondering where the best people from specializing in space tech, optics, etc went, and being leadership at NASA means you're probably not stupid, and you go to the same events as them. Also as NASA leadership, it would have been a pretty logical next step for your own career.
I don't doubt that people outside of the NRO had no idea what they do there, and that people lower down the hierarchy didn't know about it, but NASA leadership must have known there was a shadowy org working on cool satellites.

I’ll let you take that piece of information and decide if NASA leadership knew about the NRO or not when Hubble launched in 1985.
Launch vehicles are effectively ICBMs and a significant body of NASA staff is former USAF. I wouldn't say there's "no reason" A huge number of NASA employees and contractors absolutely have clearances (even if just incidentally.)
If NASA was having visible issues and difficulty in trying to get something like Hubble working in space, then perhaps the US’s spy agencies (known or not) also had the same difficulties. NASA employees wouldn’t need to have known about the NRO to help provide cover for their capabilities. Just publicly showing their struggle - for transparency - would have been enough.
(If NASA had a clue about the NRO capabilities or not, I doubt they would have cared. They still got their space telescope!)
https://www.google.com/search?client=firefox-b-d&q=perkin-el...
Whether any of that information would be allowed to go in the reverse direction back to NASA is another question entirely...
It makes me wonder about things like AR/VR, where, likewise, things are just starting to hit the lit sphere, with great difficulty; does the military already have tech that's 3 or 4 generations ahead?
If you think the public DEM/DSM datasets like the ASTER GDER v3 or SRTM GL1 V3 are pretty good, I would bet that the DoD has things far more accurate than those as digital models of the surface and built environment of the earth's surface.
It was good enough then to track individuals movement and 'replay' where they had been over the last few days to figure out where they came from and associate them with other people/ vehicles/ rf signatures.
I think it's safe to assume that the quality kept quietly improving from orbit since then- it's just too good to publicly release / declassify.
"Space internet?" It's regular internet from space available anywhere open to the sky. Seems like it would be incredibly profitable.
https://en.wikipedia.org/wiki/United_States_Space_Surveillan...
Much as the US is aware of the orbits of their satellites.
If you already assume that it's hard to 'hide' the existence and orbits of your satellites from an advanced observer with good telescopes and ground radar and ways of correlating the data, the fact that your ocean surveillance satellites emit radar might not be a problem. No need to be passive about it.
There isn't much need for stealth in all this the same way there isn't for an optical spy satellite. The adversary knows it is there and what it is looking at. The adversary just doesn't know its exact capabilities, and there's not much they can do about it being up there that doesn't lead to a sudden military escalation of some kind.
I suppose even higher and you could start resolving things like license plate numbers from space, but it just seems like sharply diminishing returns in general.
[1] - https://xrtechgroup.com/who-has-the-highest-resolution-satel...
Different thing. But in answer to your question, revisit time and immediate availability of data would be a major thing. The size/scale of the commercial earth observation satellites that have been launched are quite small and likely nowhere near as capable as even what 'black' programs had 20 years ago. Or even having the capability to get near-realtime live visual spectrum imagery for military command/control purposes (e.g: Is that long boxy vehicle rolling out of a warehouse right now a regular semi truck or a transporter-erector-launcher?).
Much rather contribute that amount one time to OSM and have details from all cities from there.
I mean, it sounds like $4k and maybe again as much on compute could fix OSM for a city?
Pocket backdoors.
For a while just before smartphones, at least 15 years ago now, carriers were experimenting with APIs that allow opted-in dumbphones to be triangulated (via cell tower) and tracked via API.
They rolled their own.
If they had such "eyes" on our earth, couldn't they have clearly spotted those Methane emissions from Turkmenistan well earlier than the UN MARS program did? or many "beneficial" to humanity things I cannot even think of right away.
Even militarily... US wanted to avoid the Hormuz Strait closure.. I think that was a clear enough military goal. Could nt they spot where the mines are, and where the attacking positions are from their mighty tech instead of this prolonged war? As in, the strikes they did already - couldnt they have taken out all attacking capacity right away if they had such powerful tech eyes?
4 years ago, people didn't fill their pockets on the current scale, and they also didn't pitch their own businesses under the cover of national interests.
Decades ago I wrote a paper, lost to time now, on the effect of his military purges on the fighting effectiveness of the Red Army during the back half of WW2. He purged not just senior commanders but mid ranks and up, think like down as far as their equivalent of majors. A vast amount of battle-relevant experience was swept away, much more damaging in the day-to-day grind than simply disappearing a few field marshals.
My point is, hope is not lost for the US military. Yes lots of irreplaceable senior experience is being tossed aside for unforgivably stupid and pointless reasons, but there's a lot of recent, hard-won, actual shooting war experience in the officer corps which, if they don't all bugger off in disgust, will serve us well in future. Today's captains and majors are well aware of how drones in Ukraine have changed battle[1], to give one example, and the career-minded among them will be in doctrine-influencing and development positions before too long.
I'm aware this is to some degree wishful thinking.
[1]I chose this example because it's going to be one of that drunken fool's more consequential errors: re-tasking the Army unit charged with developing drone capabilities for the US.
Yes, but that would "show their hand" - secrecy has always been paramount.
Of course, then Trump came in and freely shared sattelite photos of idk, an Iranian launch site or something which revealed the US's current day spy sattelite capabilities.
stop making excuses for people you don't even know
You can call back to Major General Smedly Butler and his "War is a racket".
WWII got the US out of the remnants of the great depression. The massive industrial push for both our equipment and the lend-lease model was a massive infusion into our economy. It was so huge, that it never really stopped. Our economic model and system was sick, and the military industrial complex(dramatic but apt term) was a large-scale make-work endeavor that would double as an expression of global power and propaganda both home and abroad.
One could take this and begin to see that conflict may be instigated for the sake of the MIC. Al Qaeda wasn't in Iraq, but it didn't stop us from invading, making up claims of WMDs that couldn't be substantiated, then destabilizing the region. The power vacuums then create later conflicts, for more military machinery to be built for.
The HMMV was continued to be sent to the middle east long after we all acknowledged they were death traps for soldiers. Same thing for certain tanks, they kept making them to keep people employed.
The big thing now, is the propaganda worked too well, and we became too focused on giving as much taxpayer dollars to lockheed and raytheon as we could.
We didn't win Afghanistan, Iraq left ISIS in it's wake. But the point wasn't to win, it was to brutalize(externally facing propaganda) and sell weapons. Since the purpose of conflict was so extremely warped to enable the MIC, winning didn't matter, and our ability to win corroded greatly. We won WWII because of our logistics. Those logistics have broken down as we deindustrialized and moved to more and more expensive "smart weapons". Those smart weapons made promises of warfare so advanced, you only need a handful. So we pay millions per missile. Then we use them all up defending against dumb weapons, and we lack the capacity to make more.
Our military is in effect a paper tiger. The real threat of the US military is mass civilian casualty. If we can't take them out with drones, land invasion would be a catastrophe, and then actual WMDs would be deployed to save face. Nuclear genocide is the US military's only real remaining card, as we've devoured the propaganda and rested on our grandparent's laurels while losing sight of what earned the respect.
I think the war has been a lesson that the technological capacity isn't magic and US strike capability is not unlimited. Everyone assumed they were going to do a Venezuela or Ukraine "special military operation", decapitate the leadership, strike a few barracks and declare victory. Now the US leadership seem surprised that the Iranians are continuing to fight.
(The definitive film on insane US leadership is of course Dr Strangelove, a film that came out when Trump was 18 years old. The character of General Jack D Ripper is shown to be an insane conspiracy theorist babbling about commies and fluoride who starts a world-destroying nuclear war on his own initiative)
When you say "everyone" do you mean "everyone in the US military establishment"? I remember very few independent commentators who suggested the US intervention in Iran was a good idea. (Personally I think it's too early to say.)
The last US troops withdrew from Iraq this week. I wonder how long the US will be able to tolerate not having an overseas ground war.
Not to mention if it were made public, how could it be done without exposing the technology?
“US govt sees massive methane emissions”
“How?”
“Uhh, satellites.”
“Which ones?”

> in comparison
The total 2026 US Defense budget is 1.06 Trillion dollars, or ~1,060 Billion dollars. NASA's 2026 budget is 24.5 Billion dollars, or 2% as much as the defense budget.
You chose to single out the Space Force, which has the smallest budget of the 5 branches of the US military. For contrast, the Navy's budget alone is 235 Billion $, close to 10x NASA.
For further comparison, the R&D budget of a single private company, Apple, was $34B in 2025.
I propose to compare aerospace with aerospace.
[1] https://en.wikipedia.org/wiki/2012_National_Reconnaissance_O...
The navy was up there to maintain superiority over water. The airforce over the air. The army likewise.
But nobody clearly owned maintaining superiority over the domain of space and any operation that needed to ensure uncontested operation in space was a joint agency nightmare.
Space force is chartered to provide superiority in space so the other services can conduct their operations up there. Space is clearly a specialization that is differentiated from the air.
It isn't much different than how the Air Force was eventually carved out of the Army Air Corps.
https://en.wikipedia.org/wiki/List_of_NRO_launches
"Air Force", "Space Force" are maybe well known to the general population, not many people outside of military/government/tech circles even know the NRO or NGIA exists or what the acronym means. The line gets a bit blurry between Air Force money spent, NRO, NSA, in some regards it's just better to think of it as buckets of how things get labeled within the larger DoD.
My personal favorite mission patch: https://en.wikipedia.org/wiki/USA-247#/media/File:NROL_39_ve...
The mission scope of the various intelligence agencies has evolved a lot over time as capabilities and requirements have changed. Even the histories of how these independent agencies came to exist is pretty interesting.
And yeah, that mission patch is fire.

Although the new title is four words long, the agency will officially use a three-letter acronym. This is by design, according to NGA officials, who feel that the new title more accurately reflects the agency's true mission, which is to provide intelligence and analysis rather than simply reproducing maps and imagery.
There is one NGIA on the Wikipedia page, in the title of a document from 2014:
https://www.governmentattic.org/11docs/NGIAoigGAMPC_2007-201...
So more like a common misspelling?
" "NGIA" intelligence mapping"
It'll turn up a ton of results where people external call it NGIA including a number of .edu sources...
In some ways I guess it's a bit of a stylistic choice, putting a letter for each of the four words of its name, much as how BBC News does not always capitalize all acronyms. Copy and pasting from their style guide:
"acronyms
Use the abbreviated form of a title without explanation only if there is no chance of any misunderstanding (eg UN, Nato, IRA, BBC). Otherwise, spell it out in full at first reference, or introduce a label (eg the public sector union Unite).
Where you would normally pronounce the abbreviation as a string of letters - an initialism - use all capitals with no full stops or spaces (eg FA, UNHCR). However, our style is to use lower case with an initial cap for acronyms where you would normally pronounce the set of letters as a word (eg Maga, Sars, Aids, Nasa, Opec, Apec).
There are a few exceptions:
The National Institute for Health and Care Excellence is capped up ie NICE
Special educational needs and disabilities becomes SEND
The UK Independence Party is capped up ie UKIP
Strategic Health Authority becomes SHA ("Sha" looks like a typo)
Seasonal Affective Disorder becomes SAD ("Sad" would be confusing)
Where a capped-down acronym risks being misunderstood as a word.
For names with initials, we avoid full stops and spaces (ie JK Rowling and TG Jones).When abbreviating a phrase, rather than a name or title, use lower case (ie lbw, mph)."
> NASA's total enacted budget for fiscal year 1996 was approximately $13.9 billion
> a 1996 bipartisan commission report noted that the NRO possessed "by far the largest budget of any intelligence agency," and contemporary experts track the broader military space budget at roughly $10 billion to $11 billion annually for the NRO alone
So pretty similar budgets. The NRO imaging lens used in Nancy Grace was manufactured in 1999 but planning started in 1996.

We don't know that. The competition (USSR/Russia) also keeps secrets, and not being a free society, has much less reason to publish them later.
Another perspective on this. We currently study life with a planetary sample size of 1. Just a single additional example, especially one with a completely different origin, would almost certainly change many of our most basic assumptions about what life is and how it works.
It would also lead to a significant power shift in the religious world where individuals have proclaimed their version god as absolute for thousands of years.
An event like this would end up kicking us out of this era, and into another joint-species belief system... Only time will tell if it'll restart the cycle over again or if something new comes from it.
It was made wrong (the mirror was shaped incorrectly).
Luckily the HST was designed to be serviced (it had components within it that would degrade over time, and some components could realistically be upgraded as technology became better), so they swapped out the optics so that it worked with the incorrectly shaped mirror.

> I don't think the USA could keep mega-super-duper technology hidden from others in the long run.
The only things being hidden are basically trade secret stuff, e.g. better materials, better software, better sensors, etc...
The US had a geopolitical advantage keeping their sensor tech secret. Other nations didn't know how good they were and only hid their actions to the degree they thought shielded themselves. When the knowledge eventually came out, other nations knew if they wanted their sercets kept, they would have to invest in better obfuscation.

> And NASA often wants more money - just take the whole search for life on planets. This is so pointless - life exists already here. What is the addiction to want to find life outside of the planet? Other than, of course, getting more money, which is understandable, but it doesn't answer the question.
Since you're not behind the rationale of curiosity, I'll present you with a utilitarian justification:
Ancient Rome had steam power (see: Aeolipile). But it was basically seen as a useless toy. It took almost 2 millennia until the Industrial Revolution happened and steam power took its rightful place in our history. Humanity got there, but it took a lot longer than it needed to.
Imagine what would have happened instead if Ancient Rome could have looked across an ocean and seen a civilisation harnessing steam power to its fullest. It would not have taken almost 2 millennia for them to catch up. They just needed a hint as to where to focus their attention.
History is littered with missed paths that could have accelerated our progress.
Newton was playing around with shaped glass and investigating optics. What if he heard of someone else seeing weird lines when they left their prism in the sun? He had everything he needed to stumble upon the ultraviolet catastrophe himself and we would have ended up with quantum mechanics centuries earlier.
Going back further, what if the Antikythera Mechanism's gearwork technology became widespread? What if the ancients had their own Babbage and created programming millennia before?
Penicillin could have been discovered even earlier.
All that's needed is a little observation of "Huh, that's weird" and everything spills out of that.
Investigating a line of inquiry doesn't guarantee that we're going to end up with something. So we have to investigate wide, rather than deep.
But imagine if we find an alien civilisation and make another "Huh, that's weird" observation. All of a sudden we have a higher confidence that an investigation down a specific path does lead to something new.
- An exoplanet not moving elliptically or hyperbolically? That'd focus a large amount of attention into overcoming previous assumptions about inertia.
- Lot of lensing effects and bursts of shifted light? That'd focus a large amount of attention into bending space.
- Seeing spectral lines that don't match known matter? That'd focus a large amount of attention into the strong nuclear force, exotic matter, magmatter, etc...
- An impossible star? That'd focus a large amount of attention into the processes powering that star.
- etc...
TL;DR: Finding another civilisation doing something basically changes the rate of return calculation for research.
I understand your point, just wanted to mention that that civilization would be leading the known world at the time, methinks ...
The US has a history of keeping vehicles, weapons, and operations hidden for decades, even things in the past decade.
> What is the addiction to want to find life outside of the planet?
Knowledge. Trade. Technology. Weapons. Religion. Science. Sex (lol).
