QuoteHowever, Boeing dispute these prices per seat namely because it doesn't take into account the potential 5th seat on Starliner (which can be replaced with cargo):QuoteIn regards to to the per-seat cost estimate, Boeing said that its craft "will fly the equivalent of a fifth passenger in cargo for NASA, so the per-seat pricing should be considered based on five seats rather than four." https://www.spacedaily.com/reports/Boeing_Starliner_to_cost_90_Million_per_seat_999.htmlWhat does this even mean... both Dragon and Starliner have theoretical capacity for 7 seats. ‘The equivalent of a fifth passenger in cargo’ sounds like nonsense to me, comparing apples to oranges. Is Dragon’s cargo capacity even lower than Starliner’s, never mind lower enough to justify a 35*4= 140 million $ difference in cost per mission?

... They didn't say anything about Dragon. Just the $90 million figure. Give that 5th seat number ($72 million) to Boeing as long as you do the same for SpaceX and reduce their price to $44 million a seat.

It is more about comparisons with the cost to NASA of a Soyuz seat.

It is more about comparisons with the cost to NASA of a Soyuz seat.I know there has been frequent moans about how expensive Roscosmos is, and "giving Russia $90M per seat", but on that basis alone SpaceX will cost much more if you include the development cost. Despite SX's aim to reduce spaceflight costs, the CC programme has only limited flights and high (necessarily so) safety and oversight standards. As well as limited re-use. SpaceX is competing against Boeing, not the Russians.The arguments for SX vs the Russians, are things like, independent launch ability, developing US capabilities, and US space industry, having proper REDUNDANCY so a problem with the Soyuz doesn't halt launches... etc. Removing the indignity of having to rely on Soyuz! And having their own programme as part of expanding HSF from American soil, and so being able to claim leadership etc, as well as making strides in exploration.

If you factor in the likelihood that the Russian seat price would increase over the duration of the SpaceX service, it probably comes out pretty much the same.QuoteThe arguments for SX vs the Russians, are things like, independent launch ability, developing US capabilities, and US space industry, having proper REDUNDANCY so a problem with the Soyuz doesn't halt launches... etc.You forgot the most important one; having more than one US astronaut on the ISS at a time.*26 because the two DM-2 astronauts have effectively been converted from a short-stay mission to a long-duration mission
Yes I agree that is essential; I thought of that, but that was caused by a choice to stop buying more seats, because CC was due to come on line... shortly ....
I really don't understand people implying Roscosmos is doing something unethical with their pricing. Why should they sell a service for less than the customer is willing to pay? They've kept human spaceflight alive for the nine years the other guys have been fooling around with various projects. If the boss making dumb comments is a reason to belittle the company, we really don't have much room to say anything. I'm in awe at the way they've kept the dream alive through the incredible upheaval they've endured in the last 60 years, and anybody I meet who's been involved in the Russian space program won't be paying for drinks that night. Except for the guy who drilled that hole.

Unless ISS is deorbited in 2026, NASA will need more than 12 operational flights, so they will need to buy more flights. Which will probably reduce the overall program per-seat cost, as development costs are a large chunk of that price.
Why? Isn’t this discussion about cost to NASA, rather than benefit to SpaceX of the program? Non-NASA flights benefit SpaceX by letting them leverage the NASA investment, but have no (direct, anyway) impact on NASA or its costs.

What evidence do you have that they are wrong in that statement?edit: to save some time, also consider that SpaceX has fixed costs and development costs of its own that were contributed. The CRS contract is a potential indicator of what can happen to NASA costs as the cost environment changes.

The CRS contract is a potential indicator of what can happen to NASA costs as the cost environment changes.I’m not suggesting they were (And I don’t think they are!) - I was just confused, the previous post seemed to be just a simple calculation of the cost to NASA. Literally just addition and division, so I didn’t see how other customers factored in to that calculation.

There will be no direct handover.This is also off-topic for this thread which should stay focused on Starliner. It's not off topic. The purpose was to decide when Starliner needs to launch, in addition to when it can launch.
