To Boldly Go Where Ever - If you don't know where you're going, any road will take you there, Elliott Pulham, Space Foundation
"As of yet, there are no commercial systems that can take crew and cargo to orbit and dock with the ISS. There are, of course, several such systems in development. A SpaceX Dragon crew capsule prototype was on display at the 25th National Space Symposium, and we look forward to seeing what commercial solutions are on exhibit at the upcoming 26th National Space Symposium. But financing, testing, regulating, and human-rating such systems will not be easy or inexpensive. Given the scale of investment required, and financial and technical risk that must be assumed, the markets for these systems need to be global, as they are with the commercial aircraft industry, to enable a reasonable return on investment. Yet we're no closer to meaningful ITAR reform that would open those markets."
Keith's note: Thus sayeth the dinosaur. With this kind of defeatist thinking coming out of a major aerospace business organization, one might conclude that American business is no longer up to the challenge of space. Elliott certainly seems to think so. Indeed, he clearly seems to think that the only solution is to have the government run everything, call all the shots, etc. One look at Constellation's technical and funding woes speaks to the inadvisability of this. Which is better, one monolithic approach ("on steroids") with no Plan B, or one that utilizes a variety of approaches, from multiple sources in a synergistic, flexible, adaptable arena?
