We are Ready for Commercial Human Spaceflight, Leroy Chiao

"Many of my colleagues and peers have written articles and pieces, deriding the idea of commercial LEO access. Indeed, the track record of the self-described "New Space" companies has thus far, been marked generally with failure and arrogance. Not all, but many of these folks, before they run their companies into the ground, seem to spend the bulk of their time attending self-serving, self-aggrandizing conferences where openly slinging mud at NASA is sport. This is hardly constructive, and it brings discredit to others who have serious aspirations for the future of commercial spaceflight."

Launching NASA on a Path to Nowhere: Analysis, Tom Jones

"The new budget, announced Monday, seems merely an attempt to disguise the demise of U.S. leadership in space. The president does away with Constellation, its Orion spacecraft, and its Ares I and Ares V boosters. The abrupt cancellation means the U.S. no longer wishes to send its explorers to the frontiers of knowledge and spacefaring skill. We are deliberately choosing to have no better space capability than do Russia, China, or India."

"Another former shuttle astronaut, Ken Bowersox, is more bullish on the commercial prospects - perhaps in part because he's now an executive at one of those companies, California-based SpaceX. Today Discovery News quoted him as saying that space contractors "should be able to come up with new and innovative ways" to fill NASA's needs for resupplying the International Space Station."
