He's also promoting a paradigm for the continued existence for NASA, one where it is the incubator of cutting edge technologies that then get passed on to private commercial enterprises. Before NASA was expected to build rockets and lead missions, and along the way it spun out some commercial products like Tang, Velcro, and other stuff by happenstance. Now the model is that private industry will lead commercial ventures into space, assisted by NASA for technology development and backing for high-risk prototype missions, similar to CRS.
