Just a reminder of the key things related to Starlink (since I had to go look them up - https://en.wikipedia.org/wiki/Starlink_(satellite_constellat...):

* Total deployed size will be ~12K satellites and take a decade or so. Will be operational in a reduced capacity as early as next year.

* Since they're in low earth orbit, latency could be in the 35ms range.

Some people on the Spacex subreddit calculated that the upcoming Starship vehicle could dispense over 500 Starlink satellites in one launch: https://www.reddit.com/r/spacex/comments/bnjrnf/elon_musk_on...

I believe the 35 ms latency number is on top of any required routing latency, either on the ground or in space. I'm curious how much each satellite hop will add.

this guy made an excellent youtube video modeling and visualizing the satellite orbits, the network routing paths across them, and the resulting latencies: https://www.youtube.com/watch?v=QEIUdMiColU&t=4m

NYC to London on the current internet is 76ms, he shows it across starlink's updated plans as working out to around 46ms.

Later in the description he points out a mistake in his own math and says that starlink paths should be 8.7% faster than the video shows, so really jfk<->lhr ~ 42ms.
