About 15 minutes into the news conference, NASA Associate Administrator for Science Nicky Fox mentioned that one way to reduce MSR cost would be a smaller MAV. About time.
On the other hand, in subsequent Q&A she said no time for technology breakthroughs, must rely on high-heritage technologies. They plan to solicit new mission ideas from industry and NASA centers (as has been done multiple times over multiple past decades). About a half hour after the start of the news conference, the Washington Post reporter pointed out the seeming contradiction between "whole new approach" and "heritage technology." (submitted here about halfway through the news conference) |

About a half hour after the start of the news conference, the Washington Post reporter pointed out the seeming contradiction between "whole new approach" and "heritage technology." It would seem clear from the context that "whole new" means applicable technologies new to this specific mission plan and "heritage" means applicable technologies established previously in the history of spaceflight. So there's no contradiction, but it remains open if the intersection between the two sets might be the empty set. The Washington Post writeup (behind a firewall for non-subscribers) doesn't mention this question, but quotes Bill Nelson as saying that: 1) A previously-projected cost increase from ~$4B to ~$10B is unacceptable. 2) A previously-projected delay to a 2040 return is unacceptable. Further quotations from Nicky Fox, Scott Hubbard, and Bethany Ehlmann play out the dialectic that a cheaper outside-the-box solution that doesn't increase risk is desirable; desiring that doesn't mean that such a solution exists; but they are seeking such a solution now. |
