While I appreciate the main message of Zubrin’s article — that the SLS and Deep Space Gateway are fundamentally irrational pieces of hardware and that SpaceX offers transportation services for a tiny fraction of the price — it appears to me that he glosses over the true cost of such a moonbase: developing and building all the necessary hardware that he describes and which currently does not exist. The list is long: various sizes of H2/O2 rocket engines (would have to go to Blue Origin for those), lunar landers with 12 ton payload capacity, solar panel arrays suitable for use on the moon, high-data-rate communications gear for use on the moon, microwave power-beaming set up with a range of 100 kilometers, two crew vehicles for use on the lunar surface, a “trailer”, and a group of tele-operated robotic rovers, 12-ton lunar surface habitation module, Lunar Excursion Vehicle (LEV), electrolysis/refrigeration unit to convert mined water ice to hydrogen and oxygen, and probably other major pieces of hardware that I have missed as well as a large number of smaller pieces of hardware that he does not list.
It will cost billions to develop and build all that hardware. I’m fine with cancelling SLS and DSG right now and diverting all that money to the project Zubrin proposes, but the reality is that is not going to happen because powerful senators will not allow it
Regardless, I applaud Zubrin’s proposal and am happy to see him call out the SLS and DSG for the ridiculous waste of money that they are.
