This is the fourth good Starlink launch in May, 2021.

There are 1638 good Starlink satellites in orbit.

Viasat is begging the FCC now to stop SpaceX from crushing Viasat. Viasat will go to the courts to try to stop SpaceX Starlink. Viasat is using the excuse of needing an environmental study to be performed.

The FCC granted SpaceX's request to lower the altitude of future satellites in the Starlink Low-Earth Orbit (LEO) constellation. The FCC's decision in April came despite protests from Viasat, Amazon, SES, and other satellite competitors.

The translation of the FCC protests is SpaceX competitors saying :
– help us. we are unable to compete against SpaceX. Either we cannot get our satellites into space or we have satellites that are forty times higher so they take 0.6 to 0.8 seconds to communicate with customers (latency).
– help us. Our high-altitude satellites are about to become worthless.
– please FCC stop or slow airlines and the military from being able to use a faster and low latency service.

You can also go to the Viasat blog where Viasat explains why latency is not a big deal. Viasat has some software and network prediction to minimize the latency lag. This does require them to guess what information you might need and waste your bandwidth if they guess wrong. Viasat also has quite low monthly data usage limits.
