Robot Spaceplane To Launch In 2008
FleaPlus writes "The US Air Force has announced that it is developing an unmanned reusable spaceplane, the X-37B Orbital Test Vehicle. The first launch is in 2008 on an Atlas V rocket. The X-37B will be one-fourth the size of the Space Shuttle and serve as a testbed for technologies for future reusable spacecraft. Its predecessor, the X-37, was drop-tested from the Scaled Composites White Knight mothership earlier this year."
Do you have any idea the wide variety of orbits used by satellites?
Do you have any idea the fuel costs it would take such an "interceptor" shuttle to move amongst these orbits?
A missile can do it simply, cheaply, and now. Occam's razor suggests they wouldn't build such a complicated ship for such a simple mission, and that your conspiracy theory is unfounded.
From everything I've read about the Space Shuttle design process, a major goal in making it reusable was to reduce the cost of getting into space. However, several competing interests within the government saddled NASA with conflicting demands. Attempting to satisfy everyone with one big multi-use tool made the whole system much more expensive to operate and maintain. It also strained the definition of "reusable" by needing major components that weren't reusable at all, and requiring the Shuttle itself to be almost entirely rebuilt between launches.
Now we're seeing more specialized designs. Heavy cargo launchers can be much cheaper when they don't have to carry people. Crew launch vehicles can be made safer at less cost if they aren't also being asked to carry heavy cargo loads.
The X-37B, if it leads to spacecraft that are truly reusable, could be another step toward making everything we do in space less costly and more productive. In the long run, that goal is far more important than any other mission in space, whether the short term goals are military or civilian ones.
Subsidization of the economy through the Pentagon system suggests a complicated ship for a simple mission would be acceptable.
If the US went to war at some point in the next decade or two with Korea, Iran, China, etc., it would likely need the ability to rapidly re-deploy satellites that are knocked out. In case you think an altercation between China and the US is unlikely, they've reportedly already started messing around with US spy satelites by shining big ground based lazers at them (possibly to blind them).
Something to think about: if China or another nation knocked out an unmanned facility in "international" territory (e.g. a satelite) for whatever reason, do you think the US would go to war over it? Having a quick launch capability or ability to change orbits for existing satellites gives another option that doesn't involve applying force, such as "impounding" said country's space hardware.

Doc, those people aren't starving. When the government says some people "have hunger" or "food insecurity", it's really the literal meaning. Sometimes they're hungry. That's not the same thing as starving - if you ever see a TV segment on this the thing that will jump out at you is most of them are grossly fat.
So no, 12% of Americans are not starving. Additionally, the government is getting these statistics from bureaucrats that want a bigger budget, who in turn are asking people on public assistance, in effect, if they want more money. So this number is very suspect even for what it is.
If you dig deeper you'll find these are people who are "falling through the cracks", and by that I don't mean there aren't programs to help them, I mean they aren't doing what they need to do to get the assistance that's available. So money isn't the solution to this problem.
The Airforce has data from the X-15, the SR-71, the Space Shuttle, the Delta Clipper, and pretty much everything from the X-30 through somewhere in the X-40's. They don't need the Japanese design. What they need is funding, commitment, and trust. Three things that the executive branch of the US Government fails in spades to provide.
