As one who worked very closely with NASA in Huntsville, AL - Houston, TX and Cape Canaveral, FL, I can tell you the NASA of today is "not as good as the original" NASA of decades ago.
NASA has suffered the damage that occurs in almost every Government Bureaucracy focused on the appearance of competency and compliance with politically correct social experiments and junk science --- it becomes incompetent and dangerous to the public welfare.

I was working at NASA Ames when one researcher glumy announced one day that NASA had reached a milestone: one bureaucrat for every researcher.
