The „Five-hundred Meter Aperture Spherical Telescope“ (FAST) can deform its wiremesh mirror to target different directions and to remove the spherical aberration issue by turning the surface shape into a paraboloid. If that’s possible for a robotically constructed and maintained structure is more than questionable. https://en.m.wikipedia.org/wiki/Five-hundred-meter_Aperture_Spherical_Telescope https://en.m.wikipedia.org/wiki/Five-hundred-meter_Aperture_...
