I was jolted a bit when I read the amounts and requirements for commercial crew last week. Not that Boeing got more than SpaceX, but rather that $6.8B is budgeted for a developing a couple of commercial capsules to fly on existing launchers. Boeing’s $4.2B doesn’t bother me as it should be expected of traditional contractors, SpaceX’s $2.6B does.
I am not going to suggest that human transport vehicles to LEO should be trivial or cheap. I do suggest that SpaceX requiring $2.6B to finish development of Â a capsule that is supposedly almost ready to go, even including the maximum 7 flights, is well out of step with the reported development costs of that company. It has been said quite often that SpaceX developed the Falcon 1, Falcon 9, and Dragon 1 for under a billion dollars.
My question is, why should capsule development cost on the order of triple that of an entire Falcon 9 launch vehicle? This is not to trivialize the work to be done, or the paperwork involved, but seriously asking what is so complicated and expensive inside that vehicle that drives the cost far beyond that of entire launch vehicle families?
This post might be considered snark. That is not the intention. It is a serious puzzle that affects development of the solar system. A puzzle that I can’t yet understand. I am not real interested in the standard NASA bashing response of how the government drives up costs that we have all rehashed a hundred times. I am interested in any solid information on the hardware/software cost drivers of this bus without a main engine.
