Ask HN: Book (or resource) on costs to travel to space for fiction book?

Hello HN Community. I think this is the best place on the internet to ask for this. I am writing a satire novel in which the first crewed mission to Mars has place.

Although it hasn't to be 100% realistic (and it isn't part of the plot), I'd like to try to be faithful to reality. Is there any book that explains more about the costs of a mission like that, different industrial needs, etc? If it isn't a book it is welcome as well (a documentary, for example).

Thank you very much!
