Given the tremendous data bandwidth, storage volumes, and power required to handle such data digitally, I imagine that a film setup might still be simpler and a faster way to downlink the data (with little chance of jamming or cyberattack). But the cost of more advanced modern optics would also increase the preference toward extended endurance over the four or five return capsules KH-9 carried.
Improvements in computer analysis seems to have advanced enough to make processing such large volumes of imagery reasonably feasible on a more regular and ongoing basis which would also encourage more regular use which might also encourage the development of a more reusable digital solution.
Perhaps a better solution might be to use a larger number of smaller satellites each with more limited coverage but also needing less bandwidth and storage to operate?

The digital one will probably be what any 21st century KH-9 uses, simply for reasons of economy.

Apparently for 0.1 m resolution from 750 km at visible light wavelength. That's the required size. But i guess we dont really have rocket that big yet. except the unbuilt Energia-Vulkan.

If you can afford a spy satellite, you can afford this.
It isn't required to mimic your nation's broken procurement process.
Special Aromas wrote:Correct.
The question is whether you need the 40,000km2 photos available every five days or whether 1,000km2 imagery transmitted in real time are more useful to you. The NRO & CIA decided that real-time image availability was more important and KH-9 became the last US film satellite program.
KH-11 transmits data at a frequency too high to pass through the atmosphere and instead uses a relay system of other satellites before transmitting back to earth, which keeps the probability of intercept fairly low. It's also doubtful it stores any data on-board as it's unnecessary with a full-time data link.

One solution would be to put the OBC in an X-37 type vehicle which can be launched and recovered as needed.

It will have reduced takeoff weight, due to hydrogen being lighter than air. However, the nature of hydrogen requires that it be stored in the fuselage, requiring a longer fuselage that results in a loss in performance. I would say just stick with normal aviation fuel.
