@jwz If I understand this correctly, the astronomers get the full original data, but with a three day delay, while the spooks get it with no delay. Is that right? And the telescope images the entire sky every three nights. And astronomers still get immediate alerts but only if there isn't something that the spooks want to chop out near that position. I guess the astronomers will have to hope that we don't get something like a gamma ray burst too close to a satellite, which would inspire them to all look closer at that spot.
