Spy satellites orbit about 100 miles above the surface and are travelling very fast to stay in low altitude orbit. This thing is less than 12 miles up and is traveling very slow. That's a big difference in picture resolution and the ability to collect radio frequency data. They are listening as well as looking.
And, if their technology is like ours allegedly is, most likely getting 3D images better than Google street view!
Why exactly would they be studying the weather in Montana anyway? And yes, the Chinese are laughing their asses off at us.
