       | As always, this is only the case immediately after sunset, when
       | it's dark on the ground but the satellites are still in direct
       | sunlight. Fifteen minutes later they're completely invisible.

         | Sure, you're not going to see satellites. But against a dark
         | sky, you can see satellites reflecting for at least a couple
         | hours. They may not be in direct sunlight as it gets later, but
         | they are still illuminated by the atmosphere on the sunny side
         | for a while.

       | from what I have seen of the way they pack the Starlink
       | satellites into the fairing, they seem to be volume constrained
       | in the fairing rather than mass constrained, so there may be
       | additional mass budget available for little overhead.
