When near the south pole of our Moon a permanent human community is established to search for and produce water in the permanently shadowed regions there, it would be nice to have some light from above !
Would it be possible to instal a framework of mirrors in space above such a human settlement so there would not have to be worked in constant darkness ?
Within the framework the mirrors could turn independent from each other and could function as solar sails as well to withstand the gravity of the Moon.
Of course, software would be needed to anticipate the constantly changing position of the framework by changing the angle of the different mirrors independently.
