That makes a lot more sense, otherwise the SNR from 90 meters away seems like it would be … enormous.

We can see Uranus from Earth which in on a similar size/distance order of magnitude :).

Actually the angular size of Uranus seen from earth is almost a million times larger than a microbe seen from 90m (not that TFA was about seeing a single microbe, or seeing a microbe at all for that matter).

There is but a sliver of atmosphere between Earth and Uranus... and all of the atmosphere between sensing apparatus and microbes 90m away. I am curious how moon would look like if there was the atmospheric scattering the entire way there. Or if would even be able to spot Mars / Venus if we had a constant 1 atm the entire way.
