Discarding Shuttle: The Hidden Cost, Paul Spudis, Air & Space

"On February 15, 2011 a symposium entitled "U.S. Human Spaceflight: Continuity and Stability" was held at Rice University's James A. Baker Institute of Public Policy. Organized by George Abbey, the resident space expert at the Baker Institute, one might have suspected that it would be Shuttle-centric and indeed, it was. Many pertinent points relevant to the current discussion about NASA's human space program and its future (or lack thereof) came out of the presentations at this symposium."
