SpaceX to deorbit 100 older Starlink satellites

SpaceX has 5,438 Starlink satellites in orbit, out of 5,828 launched to date. The oldest still in orbit are from an initial group of version 1 satellites launched in 2019 and 2020 that lacked visors added to later satellites intended to reduce the amount of sunlight they reflect, reducing their brightness. Of those 420 satellites, 337 remain in orbit.

With those satellites de-orbited that makes for about a 10% attrition rate on satellites launched so far.
