Apr 23, 2019 at 12:41 comment added Cyclic3 @uhoh no problem! I appear to have mismatched a bracket. I do not have the ability to correct single character errors, so would you mind removing it?

Apr 21, 2019 at 13:29 comment added uhoh @PhilFrost come on now, 70m to 35cm diameter is a factor of 200 smaller, but the wavelength has changed from 4cm to 0.8 microns, a factor of 50,000! The gain is through the roof for the spacecraft, and the telescope in LEO can be another 10x in diameter. For a complete analysis, including how to do the noise analysis for an optical link where you can do photon counting, we'll need a new question post.
Apr 21, 2019 at 13:01 comment added Phil Frost "the "dish" shrinks from a huge steel monstrosity to the mirror of an optical telescope tens of centimeters in diameter." To maintain the same antenna gain, yes. But doesn't the FSPL increase by the same factor?
Apr 20, 2019 at 16:49 comment added GdD I love how the super-intelligent machines that discovered Voyager 6 could build an enormous spacecraft to travel the galaxy back to its origin but couldn't wipe off a bit of corrosion on the the nameplate!
