They are supposed to automatically de-orbit in ~5 years (atmospheric drag) if they are DOA based on a quick search. That does mean that they are space junk for a while but not permanent space junk.

Heh, its kinda sad that noone mentions space environment impact at all. How that 40k sats will pollute already decently pulluted orbit.
I wonder if decommision process will be clean (burn in atmosphere). If there will be failure rate, we will end up w/ dead sats at orbit.
I really wonder if thats really necessary. I think that money could be better spent building earth infra reaching those under-serviced places. Cheaper, easy maintenance, less centralization.
We also need orbit for more importand sats out there than internet. GPS, earth monitoring infra, space telescopes, R&D.

The principal barriers to another launch are a successful test of the new water deluge system, and qualifying a more advanced flight termination system.
The fact that not only they tested WITHOUT a water deluge system the first time, OR a flame trench, is why the Cult of Musk will continue to hold them back. It's fascinating to me to watch him 'discover' solutions to problems solved 50 years ago that he chose to ignore.
The environmental impact was far less than believed. An analysis of
the dust spread across town was shown to just be sand, not vaporised fondag, as thought.
The easily predictable environmental damage around the launch area still exists and is significant, and will take them months to clean up via the terms of their contract with the state of Texas.
There is really massive construction going on, replacing the existing
megabay, the damaged tanks are being replaced rapidly, the launch site has been dug out and partially repaired, and a new launch license was issued for the next 6 months last week.
Also here, the fact that they even have LOX and CH4 thanks THAT CLOSE to the pad itself is borderline negligent, but still absolutely mind boggling.

Starship is years away from being flight ready. The most recent test launch from Texas was not a 'successful failure' as widely portrayed in the media. Reputable people who have been working in this field for decades have pointed out tons of massive problems that are not quick fixes.
1) I agree that they are years from flight ready, however the improvements in the queue for the next launch are already impressive. A lot of nay-saying concerns have been addressed since the launch.

While the everyday astronaut and starbase_csi can be thought of as fanbois, they are also producing the most quality reporting and analysis that exists:

They are good folk to track.

There are an amazing number of individuals reporting on daily progress, with live video feeds.

The next ship and booster will possibly be tested next month, and these have replaced the hydrolic controls with electric and have better motor shielding in general.
Yes, an utterly amazing amount of things need to go right to launch a spaceship, but ... my best bet for another launch of starship would be early september.

But your calculations don't take into account that they are not at
anywhere close to a full constellation: they are only at 4k out of the 40k
I mean, this could be a spectacular flop like Iridium but a lot has
changed in 20 some years not least of which is the cost of launch.

- Starlink currently reports around 1.5M subscribers. At $110 a month,
- A Falcon 9 launch is billed out at $67M. A Falcon 9 can carry up to
60 Starlink sats. That's ~667 launches to reach the stated goal of 40k sats in the constellation. So roughly $45B in just launch costs, if you assume
- The reported price per sat is $250k.
Assuming they give themselves a friendly internal discount, the orbital buildout cost are in the neighborhood of $30B for launches, and $10B for sats.
- The satellite failure rate is stated to be ~ 3% annually. On a 40K cluster, that's 1200 a year.
That's about 20 more launches a year, and $300M for replacement sats. Let's round off and say that's $1B a year there.
So far, that's a $40B buildout with a $1B annual run rate. And that's just the orbital costs. We haven't even calculated the manufacturing costs of the receiver dishes, terrestrial network infra cost , opex from staff , R&D, etc .
Numbers kinda speak for themselves here.
I mean, I get that Musk is sort of a cuckoo bird but say what you will he does have big ambitions.
Ambition is good. But reality tends to win the day. As does math.

Unlikely. They will remain niche. The economics don't make sense for
Why would they put up 40000 satellites if their ambition is only

From my standpoint, they don't have to completely replace the
incumbents. I'd be perfectly happy just keeping them honest.

about. I was talking about the home dish costing $1k. That sounds like it could easily be reduced significantly unless there is some underlying tech reason. they need so they literally can't support higher numbers. Their new generation of satellite is also suppose to be doing some in-orbit routing or something like that which would I would assume will really help on the bandwidth front. How much that affects their maximum subscriber base when they are fully deployed I don't know but it's bound to be a lot more possible subs than they have now. the real economics. I'm pretty sure they've been purposefully throttling demand because they still don't have the capacity so it would make sense to overcharge in the mean time. Is there something inherent in their cpe that makes them much more expensive than, say, satellite tv dishes? I can see marginally more because of the LEO aspect, but isn't that mainly just software? It wouldn't surprise me that the main cost is the truck roll. that's $165M in revenue, the public launch price. (Because if they are launching their own stuff, they aren't launching an external paying customer.) those services to completely replace terrestrial only service. the real economics.
