This is unbelievable.
- giantrobot 6y agoWhile that's an impressive zoom, the camera is moving much slower relative to the targets (~0km/s) than if it were in even a low orbit. It's also imaging people at the extent of its zoom at only a few km away. In orbit it would be hundreds of km from its targets. CubeSats and other small satellites can capture useful imagery but they're not spy satellites. There's optical limits to their capabilities because of their size.
