JWST is fairly old tech now so probably better - by better I mean in some colloquial sense based on the passage of time, i.e. JWST would be pretty useless pointed at the earth one imagines.

If OP is correct about 10cm, that would place it at around 3.7cm. It still is incredibly poor compared to what a high flying aircraft could capture, much less a drone spraying chemicals.
- sandworm101 5y agoThere are other considerations. The atmosphere is wobbly. You can have a mirror 100f across. That won't help the distortion. The only option is active optics, mirrors that adjust in real time, something very hard to on the ground let alone in space.
