During a virtual conference briefing this week, SpaceX founder and CEO Elon Musk provided more details about a new plan that his company has to mitigate the impact of their Starlink satellite constellation on night sky observation. Musk first revealed the intent to build a “sun visor” to lower their visibility on Twitter, but we didn’t know much about how it would work or how it compared to the test dark paint job that SpaceX tried previously.

As reported by Space News, SpaceX’s new “VisorSat” approach will essentially use sun visors to block inbound sunlight from hitting the reflective antennas on the spacecraft, stopping them from reflecting said light back to Earth, which is why they appear as bright lights in the night sky.
