Quote from: Robotbeat on 04/30/2018 03:54 amSpaceX will price their services to maximize their profit and/or revenue. Novel, I know.Not in the slightest. SOP for aerospace. The surprise (for some) is that SX is not behaving in any way that's actually different from other large aerospace primes, other than the sticker pricing.

Which, by the way, is not the only such minor technical error on the hardware/aerospace elements of the document. This isn't so surprising when one considers the qualifications/experience of those responsible for preparing the EA and that those topics aren't the primary focus of the process. The preparers all have solid backgrounds in biological sciences and/or environmental management/science and are generally very experienced in the EA process but none of them are trained in engineering/aerospace/etc.:The above comment isn't meant to denigrate the quality of the work they did, but just to point out that when it comes to the nitty-gritty specifics of the aerospace side one shouldn't treat the EA as the Gospel Truth.
I think you means SOP for almost every single company ever. So expecting SpaceX to act differently to A.N.Other company when they need as much income as possible seems odd to me.
SpaceX are doing exactly what they need to do to ensure the money flows in. It going to be some years before prices for launches really drop, and until then, they need the cash to build the craft designed to bring about that drop. And what they are doing is pricing below others, but high enough to keep the money flowing in.Simples.
I'll believe SX will charge an outside customer a price equal to an F1 flight for a BFR when I see it happen.

So expecting SpaceX to act differently to A.N.Other company when they need as much income as possible seems odd to me. Most people have forgotten, but the reason is that only a few years ago SpaceX said their intention was to drastically lower launch prices with reusable F9/FH, in order to create new markets and new demand for space launch. Most on NSF forgot about that, but that is why many are/were expecting different. Feels like the hoped-for new demand still hasn't materialized.
Here's the thing. Starlink has no service to deliver right now and won't have for several years (in fact I don't think they have a date for that).Meanwhile SX is a)Building the factory for BFS b) Developing BFS now.That's a shed load of money that's going out right now. Do you still not see how your funding does not seem to match reality?OTOH the $14Bn COTS II contract has been awarded and I'm confident early payments of that are already flowing into the SX account.

Maybe a few token launches could be sold under cost, but Bezos is more concerned with funding R&D for actual ventures than for throwing money at just subsidizing launch cost for dozens of launches.I do think Blue will lower SpaceX’s profit margin per launch, but they’re not going to straight up subsidize marginal launch costs.
What exactly would he gain by subsidizing? As soon as the subsidy expires, customers just go wherever the launch is cheapest again. It won't make them any more money.

Blue Origin could price a New Glenn launch at some arbitrarily low number and keep it there until all of the competition is gone, Bezos has that kind of money.

That sort of behavior violates antitrust laws and the Military's desire for redundant launch capability, so it would have to be done judiciously, but it could be done.
