For a lucid, detailed,Â and factual review of changes to ourÂ national space policy please see this article by Dwayne Day at Space Review. I will keep an eye out for his future articles, he definitely grabbed me with this first para:
Ever since the new National Space Policy was released on October 6, partisan pundits on both the right and the left have been commenting on it with limited degrees of knowledge or logic. After reading their work, one gets the sense that very few of the commentators actually bothered to read the ten-page policy. Rather, they read articles about the policy, and comments about it by people they dislike, and then fit it into their standard partisan model of good and bad. Because all politics are tribal these days, there is no need to actually think. All that matters is whether one is a Crip or a Blood, an Eloi or a Morlock, a Republican or a Democrat. Rather than analyze and discuss, the pundits reach for the nearest rock.
He also posts at great link at the end of the article to a PDF that compares the prior policy to the new.
