Are there photos of just the Starlink satellites? I know the impressiveness of the stack of them, but I can’t tell what I’m looking at without seeing one outside of the stack. It’s like showing a photo of a geologic specimen without a scale reference.

there is a little bit of info on the starlink site: https://www.starlink.com/

One off the satellites where apparently already dead and would not respond to commands when they got it mounted on the rocket. But they launched it anyway.

Probably didn’t anticipate the delta in load in the flight plan?

The satellites stack, so the speculation is that they would have had to spend days to unstack and restack everything.

Can't wait to see every Tesla become a wifi hotspot hooked up to Starlink. Traditional ISPs are in trouble if the Starlink latency is really in the sub 100ms due to the LEO distance advantage. Global coverage with decent latency! I wonder if that's why google dipped out on rolling out fiber infrastructure. Physical infrastructure is about to become obsolete as more advancements in wireless tech and satellite internet…

Keep in mind, the entire Starlink array will only be able to handle like ~1% of global consumer internet traffic. They're only a handful of gbps downlink each. ~10gbps downlink.

How easy will star-link be to block, for example in Russia say or China?

Easy for start, just blast satellites passing over with comparably big amounts of rf. Or just require spacex to not provide service in your territory "or else". If those phased antennas are very good, they may block point sources of jamming by "muting" that small area, but if you pump enough energy into rf, antenna will be overwhelmed and will degrade fully. But that requires tracking each of satellites passing overh…

That is definitely not how China would enforce it.

You need a Starlink terminal in order to communicate with the satellite. China will most likely just block the sales of Starlink terminals in the country if they want to enforce a ban.

4th reuse. Wow didn't realise they were that deep in already. Thought reuse was still conceptual

Also first re-use of a faring as well, which is awesome because they're apparently not that cheap to make.

Was this fairing caught by their recovery ship or did they restore one that splashed down?

I do wonder if that fairing endeavor will come out net positive over the lifetime of Falcon. They paid for a specialized boat to catch the things, and iterated on the boat design several times.

Starship is the real reusability project; Falcon is now just holding on to revenue while they get Starship ready to take over the entire launch market (including their own).

The fairing is passive, I really wonder if it would have been more cost effective to try and reduce the fairing cost to a (few) hundred thousand bucks or so instead of going to all the trouble of catching it.

Although maybe this is best seen as R&D cost for the eventual Starship architecture?

20 Gbps per satellite, according to the FCC filings.

Which isn't that great.

The ones that flew today were fished out of the water after the Arabsat-6A mission. The two that they've caught with the boats were from STP-2 and Amos-17.

Apparently they're going to attempt to go fish these ones out, too, since the boats didn't head out today because of rough seas.

But if you remove all streaming/porn/torrent traffic it would be able to handle a lot more of the global traffic.

I've been thinking about this, and it seems doubtful. The fairings are under a million dollars apparently, so they'd have to recover many dozens if not hundreds to pay back the investment into all the catching technologies. It's not clear that they'll ever use that many fairings before switching over entirely to BFR.
