Re: Infinite loop
Yes, we spent alot on Apollo. But we went from a suborbital 15 minute manned flight to walking on the moon 8 years later. Orion isn't doing anything new, and is just the capsule.
NASA contracted with SpaceX to design, test, and send crew to the ISS in the Crew Dragon capsule. The testing included an abort test, an unmanned test mission to the ISS, a test manned mission to the ISS, and up to 6 crewed missions to the ISS. The contract is for a maximum of $2.6B. While the Crew Dragon is smaller than Orion and isn't currently moon capable, it costs pennies relative to Orion.
And then there is SLS........
