Starlink Satellites Are Still Bright - Astroguyz on SpaceX's rapidly growing Starlink satellite mega-constellation -
The problem for astronomers didn’t really become apparent until the first launch of 60 Starlink satellites in May 2019. To date, SpaceX has launched Starlink batches at a breakneck pace, with over 2,900 total deployed and 2,286 still in orbit and in service as of early August 2022. SpaceX ultimately wants to put 12,000 Starlinks in low Earth orbit with provisions for a possible 30,000 more. The Starlink internet service went live in late 2020.

This has included painting the coffee table-sized satellites black, adding visors, stickers, and angling them edge-on to the Sun during twilight passes. ‘VisorSat’ helped to lower Starlinks down by about a magnitude… but the newer generation of Starlinks do not incorporate this feature, as a visor would interfere with the new line-of-sight laser communications between satellites.
Also, the attrition rate for Starlink seems pretty high: already, 218 satellites have reentered, including most of the
