Satellites have had the ability to do that for decades. I was in the military during the Reagan administration and we would roll $weaponsystem under cover when the Russian satellites were passing over. They could see even small details such as which model it was.

But more resolution isn't what's important. Other capabilities, such as deep infrared, ultraviolet, radio, whatever scanning is more useful. Sats made U-2s, SR-71s mostly obsolete; drones are doing a lot of what Sats did. Top of the list though is refueling spy sats. That is the Holy Grail of reconnaisance which the USAF X-37B totally experimental research craft totally doesn't do.

Refueling massively extends their use and lifespan. Its like have twice as many for the money. Cuz, ya know, a hundred ain't enough.
