It’s nice to see that the donated NRO satellite buses found a use i remember when they were initially donated everyone cried that NASA didn’t had the budget to make any use of them. I wonder what else do they have lying around, since it’s clear that what they have now is more advanced than what they’ve donated. I also wonder with the advancement in SAR technology how much longer would optical recon sattlites would even be used for because as long as the NRO still uses optical sattlites we have some sort of economy of scale that can be leveraged for cheaper space based telescopes.
