"However, former astronaut Bonnie Dunbar, now also a UH professor, argued that SpaceX and commercial flight are being touted as a solution but that the money being diverted from NASA to fund these endeavors will cost space exploration in the long run. "Industry is not poised to do the kind of research and development we need to do for space exploration," she said."
Keith's note: This is typical of the pervasive ignorance that surrounds NASA - and it comes from decades of drinking the Koolaid. Bonnie Dunbar clearly has no idea what other commerical launches SpaceX has (or its long manifest backlog), how much private capital has been invested in SpaceX, or even the nature of what SpaceX does for NASA. It doesn't do the research that she's so worried about. It hauls groceries. Someday it will fly Texans. What these people do up there - with that cargo - is NASA's call. They are buying a ride. Given the $500 million to $1 billion cost per launch of a shuttle, this is a bargain no matter how you look at it.
