More that the satellites are in fixed orbits that are relatively low (250 km) and moving at thousands of km per second. Even if the target is directly below them, they need to rotate quite a lot to see it for more than a few seconds at a time. If the target isn't directly below, they need to look much farther sideways than down.
- habnds 7y agomost spy satellites aren't geostationary?
- kragen 7y agoNo.
- ubertakter 7y agoSlight typo there: "thousands of km per second", you probably meant "thousands of meters per second". Low orbit is on the order of 7-8 km/s. I did find the typo humorous.
