I'm more worried about NASA's goals than I am their costing strategy. SLS and Orion are taking up much of NASA's budget, and I don't see the payoff. What science are we going to add with another manned moon mission? Going to the moon and returning with stuff like the Genesis Rock was important, but that's been done. Likewise I'm really not sure what science we've gotten from the Space Shuttle and the ISS, outside of biology on long-term human space flight. Whereas stuff like Voyager, Galileo, Cassini, Juno, Hubble have had _clear_ science gains, and cost much less than manned missions. Now we the Webb Telescope and Lucy, we should be doing much more stuff like that.
