@Trevorgoodchild Yeah - my take is that the State Dept assumes that anything that makes satellites fainter must be for espionage purposes. Even though with 10,000 sats already in orbit and tens of thousands more planned, astronomers desperately need all sats to be fainter in order to keep doing science at all. (Of course, I don't think we'll actually get to that many satellites before someone screws up and puts us into Kessler Syndrome, but that's a different discussion...)
