The billionaire entrepreneur said that "VisorSat" satellites equipped with a sunshade to block reflections from the sun are a potential fix. The glint makes the satellites bright enough to see from Earth and has marred some astronomical observations over the past year. Musk said the next launch of Starlink satellites should be equipped with the dimming devices.
"We will take further steps as needed," Musk assured the audience of scientists, adding that the fix is "quite simple" and "we'll feel a bit silly in hindsight."
Considering answers to Did nobody in the Astronomy community think 12,000 new satellites in LEO might be a problem? I think they should have started feeling a bit silly in hindsight a little earlier, but that's a different topic.
Question: How will SpaceX's VisorSat work? How could a sunshade articulate to shade parts of Starlink satellite as it orbits the Earth?
Highly relevant (and currently unanswered): What attitudes will Starlink satellites have in different orbits?
