They added the sun shields in mid-2020, after several hundred satellites had already been launched. Those remain visible, and make up about 8% of their fleet today.

Kinda makes me wonder what we're going to do about all these satellites in 50-60 years when there's thousands of decommissioned ones floating around.

They deorbit themselves after about 5 years... so if starlink goes tits up, at worst you'll see the satellites for around 5 years. Sooner if they are intentionally deorbited.

They’re easy to knock out of orbit and auto decay because of the light atmospheric drag. Shouldn’t be a problem.

Higher orbit debris could last a lot longer.

Starlink satellites are visible with a 20x80 binoculars, shortly after sunset, in the west. Later they aren't visible at all.

I do a little stargazing with binoculars.
