In answer to the original poster's question: IF VSE gets cancelled, will that be the end of humans beyond LEO? I think that the answer to that question would be yes, for at least a century, if not an end to human spaceflight by the United States for half a century or more.<br /><br />WILL it get cancelled? I think the answer to that question is NO. There would be too much at stake in the realm of political prestige, especially with China launching humans, the Russians continuing to launch humans, and Malaysia now looking at launching humans into space. Politically, I think it would be "the devil to pay" is any administration or congress allowed the United States to lose human spaceflight capacity, regardless of political party.<br /><br />Will the VSE get amended or changed? The answer here is probably yes. The engineering will lead to design changes in the launch vehicle and spacecraft, as it has done with every man rated vehicle since Mercury. The stick design may well be changed in favor of something else, but eventually, Orion will fly to LEO, to ISS, as a shuttle replacement. It will be capable of taking humans beyond LEO by design. That leads to another question, how far behind Orion and its launch vehicle will come the Cargo Launch vehicle, the lunar lander, and the Trans Lunar Injection stage? The timeline and funding for those projects will detrmine, ultimately, when humans go beyond LEO again, for the first time since 1972.<br /><br />Metal is being bent, and real hardware is being tested on Orion. That part of the program is well underway. My concern is with the TLI stage, the Lunar Lander, and the "Ares V" cargo launcher. Without those, Orion will just be a shuttle replacement flying to and from ISS, and nothing more.
