That seems to assume that only the government can build a man-rated launcher. It also assumes that the government is the only customer for a man-rated launcher. Both of these assumptions are a bit suspect, I think. Taking the first one: if we really want to put some U.S. employees in space, and assuming no shuttle and no replacement NASA launcher, then there are several options. One (which is rumored to be part of the plan) is to purchase launches from other spacefaring nations. But another is to purchase launches from any other company that can provide them. Government IS the only customer for man-rated orbital space launches. Dennis Tito, etc., were stunt passengers. They came nowhere near paying their fair share for what it really cost to develop and build the spacecraft in which they flew. It their were big profits to be made in this tourism business, it would have happened long ago. Government has never built a man-rated launcher or spacecraft - it has always paid shareholder-owned contractors to develop and build them. In the past McDonnell Aircraft and North American Aviation (Rockwell) built the spacecraft. General Dynamics, Martin Marietta, Boeing, Chrysler, etc, built the boosters. (NASA's MSFC built some Saturn first stages, but never itself built a complete multistage manned launch vehicle). If, in the future, it was "any other company", what would be the difference? Government would still be writing the checks. Taking the second assumption: space tourism is about to take off in a big way. By the time ISS is completed and the shuttle fleet retired, we will at least have a suborbital tourism industry. To the extent that this industry will largely consist of U.S. companies flying U.S. passengers, this constitutes "U.S. human spaceflight," don't you agree? No. - Ed Kyle |

Exactly what is the "danger", Ed? There was was a ~5 year gap in US manned space capability back in the 1970s. The nation didn't miss it. Sad to say but manned space is not a "must have" capability. The danger is that five years becomes ten. That development problems (= cost overruns) create political gridlock that stretches ten years to forever. Think about how long it took to start building space station. Pres Reagan wanted it built by 1989! Human spaceflight is a "must have" if you intend to play the space power game, because successful national space efforts are about 1) prestige and 2) power through enhanced defense. The latter has consumed more U.S. funding than civilian space since about the mid-1980s - at the expense of the former. A NASA chronically starved for funding has become a national embarrasment rather than a source of national prestige. If NASA discontinued human spaceflight and merely sent a robot or two to the Moon, it would not be worth the money spent because it would gain no prestige and would not enhance national defense. - Ed Kyle |

How does manned space flight contribute to national defense? All military manned space programs in both the US and USSR were all cancelled because they *didn't* contribute anything to national defense. What has changed? Jim Davis |

Well, duh! The fact sheet describes Bush's proposed policy. I was stating how I would modify that policy to mitigate your concern. No offense, but I have more faith in the ability of Russian aerospace companies to deliver Soyuzes than in your ability to modify NASA policy. |

Virgin Atlantic seems to have done ok. And by most reports, Tito paid more than the cost of his flight. In other words, Energia (I think it was) made money on him. |

There's also a very strange statement about the CEV schedule: "The new spacecraft, the Crew Exploration Vehicle, will be developed and tested by 2008 and will conduct its first manned mission no later than 2014." If the CEV will be developed and tested by 2008, what's it going to be doing during the six years between 2008 and 2014? If I take the news release literally I would say about 6 years of unmanned tests of the CEV. Or perhaps the term "first manned mission" refers to some kind of operational mission as opposed to manned test flights. Or perhaps, since NASA has reverted to using the term "manned", they're planning to fly the first six years with female crews? (It makes as much sense as anything else.) My point was that I believe it is a waste of time to worry about the exact wording of the press release and I believe a lot of your comments are on that same point. Mike Walsh |

It's not just in the press release, Mike. The President of the United States said the same thing, so did the Administrator of NASA, and the 2014 date is even in the budget chart. If worrying about words is a waste of time, why read this forum? It's got nothing but words. |
