Do these correlate with a higher loss rate of LEO's like Starlink?
Yes and no. Starlink’s loss rate has to do with their two step launch process. For cost reasons, they launch a bunch of satellites to an initial altitude of much lower than LEO, typically between 200-300 km. At these altitudes, satellite drag is high and gets higher with solar activity. Then they use fuel to propel them into their operational orbit. This worked fine during solar minimum when space weather activity is low. However, as we approach solar max, this method will continue to cause more losses because of higher space weather activity. The February, 2022 incident when they lost 38 satellites was due to a moderate geomagnetic storm should have been a wake up call. That storm wasn’t even that big. If they continue to launch using this method over the next few years as we reach solar max, they will continue to lose more satellites.
