Since she will not post any more of my comments on Space Policy Online, I will just have to post them here. In response to http://www.spacepolicyonline.com/news/bridenstine-releases-american-space-renaissance-act-welcomes-comment
We will either choose to establish humans in space- to expand humankind off world- or we won’t. That is the choice and everything revolves around choosing to do so or playing games that dance around a lack of resolve.
Radiation is square one. Massive shielding is the elephant in the room and the only place to get it is the lunar poles. The only way to dip this water out of the shallow lunar gravity well is to start a new 30 year program of Super Heavy Lift Vehicle launches as the successor to the shuttle. That would be the SLS.
Abandoning the dead end of LEO and Mars is the only logical course. If NewSpace wants to redirect their efforts into lunar landers that will be fine. If they want to continue to pursue their LEO tourist empire fantasy then they will continue to be the worst thing that has ever happened to space exploration.
