Quote from: clongton on 11/24/2025 07:59 pmThe noble dream of 2 dissimilar paths to ISS crew rotation was a good idea, but that was a very long time ago and only 1 of the 2 chosen paths have panned out - Dragon/Falcon. Starliner/Atlas has been a dismal failure; no fault to Atlas.I wonder, in an alternate timeline point of view, what things would look like at this point if the situations were reversed - Starliner reliably flying crew to the ISS and Dragon struggling. In my cynical mind, SpaceX would have been kicked to the curb by now.

Quote from: yg1968 on 11/24/2025 10:45 pmhttps://x.com/joroulette/status/1993092300210122921Hmmm... another Joey Roulette story that contains about 50% facts and 50% assumptions and opinions.What Joey is missing is that the original CCtCAP contract had a 50-50 split in value: half the contract value was for final development of the crew transportation service, as well as flying an uncrewed and a crewed testflight in support of certification.This applied to both CCtCAP contracts: Boeing was to receive a total of $2.1B for the development & certification portion of its CCtCAP contract, divided over a whole bunch of milestones. Nearly all of that has been paid to Boeing, for the very simple reason that Boeing has met almost all of the certification milestones, except for returning to Earth with the crew onboard.The reason that total payments to Boeing are approximately $200M bigger than the payments for development & certification, lies in the fact that Boeing has already met some preparatory milestones for the operational crew flights. And each of those milestones also come with payouts.Joey is wrong when he states that Boeing is at only 25% progress. The development & certification phase of the CCtCAP contract is actually the hard part of the contract. Boeing found that out the hard way. Dev & cert is actually about two-thirds of all the work that needs to be completed.The original CCtCAP contract for SpaceX held a total value of $2.6B. Half of that ($1.3B) was assigned to milestones for development & certification of the Crew Dragon vehicle. Flying the six operational crew rotation missions, which were part of the original CCtCAP contract, earned SpaceX the other $1.3B.

NASA is only getting one worthless cargo mission

I believe that using a Starliner CCP flight as a cargo mission has negative worth to NASA, based on some simple math.

What do you see as the worth of this mission?I can't answer for Jim but I think that the value for NASA is having another uncrewed test for Starliner and, as a result of the renegotiated contract, NASA now has reduced its obligations to purchase 2 Starliner missions which is seen as a good thing as it seems unlikely that NASA will need more than the remaining 4 missions until the ISS is deorbited in 2030.
Not sure where "four missions" comes from. I thought a total of 20 operational CCP missions were needed, and SpaceX is contracted for missions through Crew-14. Starliner would contribute another three. We have heard that mission times might be extended to 8 months (3 every two years). Is this now a formal plan?

Perhaps that more than 4 are needed but NASA can exercise options if necessary for additionnal Starliner (or could sole-source other Dargon missions if necessary). I think that NASA's plan is to alternate between Dragon and Starliner missions as soon as Starliner is operational.
Your equation is incomplete
Your equation is incomplete, but I understand your intent. If we replace it with a more valid equation it still ignores the cost to NASA caused by the disruptions to the orderly schedule of CCP and CRS missions, plus the program costs within NASA for Starliner oversight.
Quote from: DanClemmensen on 12/18/2025 02:17 pmYour equation is incompleteFeel free to show your own math. But first, what cost would you assess to NASA (the USA) if it is unable to maintain crew rotation on ISS? What if that were $1T?
At this point, supporting Starliner probably has more to do with keeping NASA's manufacturing base intact than with actually being a backup spacecraft.
