It's even worse than this.The other issue is the size of the lens.
Resolving power is limited by the wavelength of light used (lambda) and the aperture of the telescope on the satellite (D).
Combine that with the minimum altitude of the satellite (h), to get the minimum feature size resolvable on the ground (I'll call it x), while looking straight down.
I'll have whatever he's drinking.As long as it wasn't cloudy.
Like I said, worse than this. Since the aperture is so large, it actually needs to be concave so that the sensors are all the same distance from the subject. So the telescope has to be "parabolozed" or flat to about 1/10 the wavelength, which at visible frequencies is very, very small. So 79 million meters, curved precisely and flat to about 38 nm.. . .we would need a mirror the size of
D = 1.22 L/θ
L = 6 um Avg infrared ( 6 X 1/1,000,000) = 0.000006 meters
s/R = θ
R = 1080000000000 (meters light travels in one hour)
s = 0.1 meter (10 cm resolution keeping with the 10cm resolution used earlier but in this case using infrared wavelengths which are longer)
It gives us a telescope with a mirror 79,056,000 meters in size.
