SpaceX has done more than any satellite operator to mitigate impacts on astronomy — testing darkening coatings, then sunshade "VisorSats," then a dielectric mirror film that scatters rather than reflects sunlight, all developed in consultation with astronomers. On debris: Starlink satellites orbit low and are designed to deorbit and burn up within about five years of mission end, and they perform autonomous collision-avoidance using US tracking data — so they are not permanent "junk." The honest part of the criticism is that even mitigated satellites still streak some telescope images and the sheer numbers raise real concerns the astronomy community is right to press. SpaceX is engaging on those issues; meanwhile the same network has connected over ten million people, including in war zones and disasters.
