I do agree you could in theory dog food it if with your own megaconstellation but then you have to pay for that too and compete against other megaconstellations that aren’t hobbled by also developing their own launch vehicle. I don’t see how anyone gets funding for that when there are already multiple deep pocketed players in the space.

That the business model is always a sole mfg/sole operator model. Realise this is completely different to every other transportation method on the planet. The market changes beyond recognition when you stop doing spacelaunch-as-a-service and turn it into spacelaunch-as-a-product. But for that to happen you need to get away from a launch tower that Arianspace described as "The Eiffel Tower on wheels" IE 27 000 tonnes of steel So if you do what you've always done you should'nt be surprised you get what you've always gotten.

I don’t understand your meaning. Are you saying the launch service needs to be split into its constituent components - with one company providing the launch facilities and another providing the launch vehicle?No, I don’t think I’m understanding you correctly at all.

SpaceX is under no compulsion to offer prices that are just above cost. SpaceX will make profit where they can. So don't expect prices to go that low without competition.

I agree that’s what he’s saying but I don’t follow the logic. Adding more middle men into the supply chain does what? Somehow gets a lot more satellites built?

Airliner mfgs don't run airports. Their finances are not coupled to how much business in moving goods they can attract, but in how many ships or planes they can sell to operators. But while launch facilities are so tightly coupled to the vehicles they launch, and most of those are expendable anyway that will never happen in space launch and the business will remain (relatively) tiny compared to air transport or shipping. And SS won't change that.
https://twitter.com/sciguyspace/status/1628801563824103425?s=46&t=NUvXH8X_iuI_twjBjZBghAThis revenue breakdown illustrates my point quite clearly.In 2022, even with total market dominance and a record cadence, SpaceX launch revenue was only $2.4B. Across all launch categories - Small, Medium, Heavy and Crewed.Let’s say you can double that if you count Starlink launches as revenue generating. So call it $5B.That’s basically the pot of gold everyone is fighting over. And no newcomer is going to get all of it, or even most of it, as SpaceX will continue to claim the bulk of it, even with new competition emerging.And that’s before they start dropping prices to hold on to as much of it as possible.It’s a fool’s errand for the new arrivals.

They are not net profit, i.e. do not include cost of doing business or any past investment - despite pretty much every post in this thread slagging small launch revolving around the notion of 'paying back' investment (as if that was how investment worked).

Quote from: Robotbeat on 02/24/2023 03:01 amThe only argument they could have is if they’re using it to enable their own megaconstellation without helping fund their competitor. Also, if their tech is potentially truly transformative like Stoke’s. Or if they’re just content over lower returns plus enabling humanity to become more spacefaring.So to categorise:1. Develop launch as a support service for your own constellation - that’s basically Blue Origin (if you fudge the lines between Blue and Amazon). But at much higher cost to Amazon than if they went with SpaceX. And Blue is not going for dedicated small launch, so this doesn’t support the small launch business case.2. New tech which is a category all on its own, and yes, better tech than SpaceX is indeed the one use case that I agree with. A big assumption to base one’s business case on, though.3. Atruism rather than profit as a motivation. In that case business cases become irrelevant - as long as continued subsidization keeps flowing in from somewhere.

Quote from: Robotbeat on 02/24/2023 04:29 amMuch cheaper per-launch cost than Starship. Potentially a competitive per-kg cost, too. Which means SpaceX will need to lower the price on Starship. Both of those are pretty awesome for the customer.SpaceX is under no compulsion to offer prices that are just above cost. SpaceX will make profit where they can. So don't expect prices to go that low without competition.SpaceX isn’t the only game in town. Electron, LauncherOne, Vega, SSLV and PSLV all exist a lower per launch cost for smaller payloads and you’ve got Firefly, ABL, and Relativity coming soon-ish. Even if Stoke gets their cost down crazy low to let’s say $1M, they will need to cover the costs of running the company too. Even running lean but at a high cadence that’s probably $10M/mo. That’s 10 launches a month … just to break even. That was effectively Astras plan and we see how that worked out.

They don't need to launch profitably, because launching regularly (even if it's barely breakeven on a per-launch basis) gives them free launches to test out their own spacecraft components. So it's not exactly "a support service for their own constellation," but is instead a support service for their components business.Still, this is consistent with your idea that the launch market overall is small, and whatever piece of it you think you can take from SpaceX isn't worth the investment necessary to do so.

That was effectively Astras plan and we see how that worked out.Stoke's design could get to below $300k per launch, their capacity is about a factor of 10x per launch than Astra, and Astra's plan relied on magic cost reductions of aerospace hardware, not on reuse (which doesn't require lower hardware cost, just recovering the rocket and having low refurb costs).The approach is good for hundreds per month. And with megaconstellations, that's feasible.Reuse is a near step-function increase in capacity. You can see that with Falcon going from like a dozen launches per year to now over 60 (and possibly up to 100 this year) just with first stage reuse (and fairing). With equally-rapid upper stage reuse, you could be doing thousands of flights per year.The dumb idea was to try to do massive constellation launches with expendable smallsat launchers, literally the most expensive possible approach. Stoke is neither expendable nor a smallsat launcher (it's a medium lift launcher) and they're going with an approach that could allow an edge over SpaceX's approach (a more reusable and robust actively-cooled metallic heatshield which should require less turnaround time and maintenance than the Shuttle-like Starship tile system), so the same logic does not apply.

Kuiper has secured launches on other rockets, but that just means they’re not resting on their laurels, not that they wouldn’t consider other launch vehicles for later iterations. After all, even OneWeb is launching on Falcon 9.
