Earlier quoted context omitted.

Like the Space Shuttle.

No. The shuttle boosters were expended every single launch. The Falcon 9 booster comes back and lands. Ironically, the Falcon 9 second stage is expended every single launch, but that will not be the case with Super Heavy / Starship that is in development.

No they were not. Only the external tank was expended. The SRBs were refurbished and the orbiter was reused/refurbished.

I'm so excited for Starlink! As a solo founder I do all of my support, but I like to frequently go off-roading and camping outside of cell service. I have a satellite messenger for critical things, but it still leaves me feeling quite anxious to go on extended trips. If I can toss a starlink dish in a briefcase and get fast affordable internet in the Sierra's, life will be good.

This was the fifth time this particular booster launched and landed successfully. Incredible.

Like the Space Shuttle.

i suspect the cost to refurbish a shuttle + tank + boosters is more than the start-to-finish cost of a brand new Falcon9 let alone re-flying a recovered Falcon9.

As someone who lives in the mountains of Puerto Rico and has to rely on "unlimited" cell phone coverage that data caps me and satellite internet that also has data caps.... I can't wait until starlink is up and running and we may have an option for high speed, low latency, internet for us who hate cities and love nature :)

Are these still missing laser comms?

Yes. They couldn't make them entirely burn up on re-entry so the FAA blocked them using them until they solve that. It is the risk of them falling on someone.

I'm curious what the level of risk actually is. The earth is struck by many small meteorites every day. We don't know how many, but based on how many are observed, it's probably on the order of 10/day. The last person struck by a meteorite was Ann Hodges in 1954. She was only bruised, since, like most people at any given time, she was protected by a roof. A woman named Lottie Williams was struck by part of a Delta rocket in 1997 and was also uninjured. The chance of hitting someone is tiny and even then, it's not necessarily fatal or even serious. And wouldn't SpaceX be able to de-orbit the satellites over unpopulated areas, except in rare cases where there was some sort of loss of command?

Maybe living in a world where a trip to the grocery store can have fatal consequences has warped mysense of risk, but this doesn't seem worth worrying about.

By "main booster" did you mean the big red thing? That was a fuel storage tank and yes, it was not re-used.

I believe it was actually one of the more strongly limiting factors on the frequency with which space shuttle launches could be conducted because the factory producing them could not turn them out particularly quickly.

Or get foam to reliably attach.
