Nope. That’s what’s happening here.Smart.How sure of that can we be? Is there documentation or quantitative argument that supports it?FWIW, and I'm too busy/lazy at the moment to hunt it down, but I seem to recall that Transporter is actually SpaceX's second attempt at dedicated rideshare; the first time their prices were too high, and their offering failed to gain traction until they met with smallsat company reps to find out what they were willing to pay. This would have been a few months before the current Transporter service was announced IIRC.

Quote from: Robotbeat on 10/19/2023 07:31 pmNah, there are ways to do it. Stoke’s approach is one way.Stoke hasn’t even built a rocket let alone a launch business. I don’t think it’s possible for any of the small LVs to make it just by being a launch company. It’s not that big of a market and has some significant established players. The amount of launches they would need are unrealistic. Just look at the SPAC decks for Astra and Virgin. You’re talking 40+ launches a year, which just doesn’t exist. Rocket Lab did it right by having adjacent businesses. Also note that we know Rocket Lab loses money on every launch but I don’t see anyone calling them a monopoly trying to stomp out their small LV competition.

It seems obvious that nobody's rocket launch business plan will close. All of these plans (small, medium, and large, reusable and expendable) were made when Falcon was launching at most at a rate 1/4th the current rate and fairing recovery was still experimental. So SpaceX's marginal launch costs were maybe 3x what they are now. And now, Falcon is the most reliable rocket family in the history of spaceflight and can give you guaranteed slots on short notice.
I have reservations about Rocket Lab's move into an adjacent business. It is a good move to survive, but all of these payloads are surviving at the forbearance of SpaceX. As soon as the non-communications markets become big enough, I would imagine that SpaceX would wish to move into those markets.
I'd dispute a 3x reduction in launch costs.
So I don't think most of SX's competitors will be laying down to die just yet.
<snip>The lessons from Ariane 5 are quite instructive. Arianespace had a fair stretch when they could routinely get two primary satellite payloads. As comm sats got bigger it was more difficult to find one "normal" sized and one just-a-bit-smaller that needed a similar orbit (because despite using hypergolic propellants their US could only do a single start, a stunningly dumb decision IMHO).<snip>
The Ariane 5's orignal hypergolic upper stage, the EPS have single engine start. However the later EPS-V hypergolc upper stage on the Ariane 5 ES(V) have multiple engine starts. The lower performance EPS and EPS-V stages can loft 6.6 and 7.5 tonnes to GTO respectively, so can only launch one larger payload or two smaller payloads. The Ariane G/G+/GS series with the EPS upper stage retired after 2009. The Ariane ES(V) only launch ATVs to the ISS and three pairs of Galileo navigation satellites before being retired after 2018.The Ariane 5 ECA with a non-restartable HydroLox upper stage can loft about 10 tonnes of payload to GTO. The follow-on Ariane 5 ECB with a restartable HydroLox upper stage can loft 12 tonnes to GTO was shelved and replaced by the Ariane 5 ME design that was also shelved.As larger payloads grew beyond 5 tonnes, finding a complementary smaller payload gets harder. Especially after SpaceX starts siphoning off the smaller payloads.
Happy to hear your estimate of the marginal launch costs at a 100/yr launch rate. Let's say $10 million? $15 million? It's got to be much less than two years ago at a 30/yr launch rate and no fairing reuse.

No need to bring Starship into the discussion. The Falcon of today is a much more formidable competitor than the Falcon of two years ago.

Stoke’s approach is one way.Such as?Instead of starting small and expendable, start small and reusable, starting with the upper stage and doing gradual envelop expansion tests all the way up to simulating a full orbital flight under tether or with shallow hops. Do it for the first stage, too. This is would be a more extreme version of what Stoke has done. I have seen it suggested for first stages mostly.Note that stoke can probably go a lot faster than spaceX due to the small size of the vehicle.

.....So we're awaiting A6 with the Vinci engined stg2 at present?
Quote from: john smith 19 on 10/24/2023 10:27 pm.....So we're awaiting A6 with the Vinci engined stg2 at present?The solid boosters and the Vulcain 2.1 main engine are not quite the same as the ones on the Ariane 5 ECA. So might have teething issues as well with the first few launches.But, yeah. Arianespace is waiting for the Ariane 6 to get through the integrated system test (aka wet dress rehearsal).
Refurb costs of both fairings and stages will go up with the number of landings that need to be dealt with. If that can all be done by the existing workforce all well and good but if you take on new hires then the that's a cost rise.
When I did my little cost modelling game for this SX were saying that the proportion of the launch price of the US came to $17m.
Mass production (by rocket industry standards of "mass production") can lower that a bit, but how much? Perhaps Coastal_Ron could make a suggestion? The standard aircraft industry "learning curve" was a 15% fall in unit price per each doubling of production volume. A quick Google says they've launched F9 274x, that's 2^7 roughly, which would suggest they've cut costs by 105%. IOW every new F9 US is making them money .
And something I've never quite been sure about it is how much (or rather how little) what's being made is allowed to change before the learning curve has to be reset. Obviously how it's made can change quite a lot (that's where the benefits come from after all), but how much can what is being made change?
In case you missed it, I published issue 76 of the newsletter yesterday. In this issue, I looked at how European small launch companies view @SpaceX rideshare mission pricing.

Of course those percents do compound, so it's ~0.32 or about 6M 2010 dollars. With inflation this is ~$8.5M today which actually sounds about right Quote from: RedLineTrain on 10/23/2023 04:19 pmIt seems obvious that nobody's rocket launch business plan will close. All of these plans (small, medium, and large, reusable and expendable) were made when Falcon was launching at most at a rate 1/4th the current rate and fairing recovery was still experimental. So SpaceX's marginal launch costs were maybe 3x what they are now. Same as John Smith, I'd dispute that 3x value. ~30% since Falcon launch rate was 4x less -- that I would agree.Remember that marginal costs by definition exclude stuff like paying for facilities, and to a large percent salaries (unless you're contracting / hiring just to handle that yet another launch). We actually got numbers from the times when the launch rate was 1/4 the current one. Musk tweeted $15M for yet another launch (likely marginal cost) while in the similar timeframe SpaceX accidetally released some video from investors meeting (they pulled it in a few hours, but it was too late) and there the total cost of commercial launch was ~$27M. So applying 15% learning curve per doubling combine with inflation we should get ~$12M of marginal cost. And the non-marginal part of the fully burdened cost at the 1st order would be ~1/4 t was back then (they didn't increase Falcon related employment, nor did they add new facilities) so from $12M (since 27 - 15 = 12) to $4M. So $16M cost of F9 launch now vs $27M few years ago. This is very very rough estimate, of course.
You are assuming that the personnel doing the refurbishments are just idling when they are not refurbishing. That is not a safe assumption. Not necessarily false, but not necessarily true either. They may be assigned other productive tasks when they have no stages or fairings to refurbish. Or not. As far as I know, SpaceX has not said anything about that.
And even if they are idling when not refurbishing, there is no universal standard for how to report that in their accounting. (That applies not just for personnel costs; there is no universal standard for what should be counted as fixed costs, and what should be counted as variable costs.)And that is why you can't blindly compare marginal costs; they may have been calculated using different standards.
A couple of years ago, Elon tweeted that a Starlink launch cost about $15M. I don't have the time to locate the tweet, but I remember that it was phrased as that included recover and refurbishment costs for the first stage and for the fairings, but assumed that building the first stage and the fairings were already paid for, and fixed costs were not included either. But I did get the impression that personnel costs for recovery and refurbishment were included.In about the same timeframe, he also said that the Falcon 9 upper stage cost about $10M, a new first stage about $30M, and a new fairing pair cost about $6M.
That's not how cummulative percentages work. You should calculate (1-0.15)7 ≈ 0.32, which would mean a 68% savings.
But that 15% per doubling sounds like a very rough rule of thumb, that is only true within some specific conditions. Yes, the longer you produce a product, the cheaper you can typically make it (when correcting for general inflation). But how quickly you can lower your costs depends on a lot of factors, including where in the learning curve you are. And in the real world there are often stair-step changes; it is not a continous function.
There is no generic answer to that question. It Depends.
Good interview with Dan from ABL. Listen about halfway on what he said on rideshare..

The 70+ flights that ABL has apparently sold so far demonstrates the existence of a market for non-ride-share small launch much better than ABL's CFO's opinion can. (Unless those launches don't actually involve any commitment or money by the buyers, which I can't rule out.) Rocket Lab Electron and Firefly Alpha also have significant manifests. I'd guess that a few small launchers will survive competition from each other and from 20+ tonnes to LEO launchers including Starship but small launchers may not survive competition from 2-20 tonnes to LEO fully reusable launchers such as Stoke's Nova, especially if the small launchers don't go reusable themselves.
