Air Force Sends Mystery Mini-Shuttle Back To Space 123
dsinc sends this quote from an AP report about the U.S. Air Force's X-37B spaceplane:
"The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. It's the second flight for this original X-37B spaceplane. It circled the planet for seven months in 2010. A second X-37B spacecraft spent more than a year in orbit. These high-tech mystery machines — 29 feet long — are about one-quarter the size of NASA's old space shuttles and can land automatically on a runway. The two previous touchdowns occurred in Southern California; this one might end on NASA's three-mile-long runway once reserved for the space agency's shuttles. The military isn't saying much, if anything, about this new secret mission. In fact, launch commentary ended 17 minutes into the flight. But one scientific observer, Harvard University's Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics, speculates the spaceplane is carrying sensors designed for spying and likely is serving as a testbed for future satellites."

NASA had a "designed by committee" project that threw in everything including redundant kitchen sinks and ended up with a bloated whale of a project that was highly impractical and utterly a failure at what it was intended to do: reduce costs. Instead what we got was something designed by committees of non experts that ended up with something like Homer Simpson's badly designed car [onscreencars.com] that has been an utter failure in the marketplace.
This is a classic White Elephant [wikipedia.org] development that simultaneously bankrupted NASA while disabling the development of any more feasible technologies. So we're stuck with it while NASA tries to regroup and come up with a strategy that doesn't suck.

The worst feature of the shuttle was trying to make it carry both people and cargo. That is like trying to make an airplane do the job of both a F-16 and a C-130. It is not going to do either very well. We should have designed a cheap unmanned heavy lift vehicle that was 99% reliable, and a much smaller "space-plane" to carry people that was 99.99% reliable. Instead we built a really expensive manned heavy lift vehicle that was ~98% reliable (135 launches, 2 failures).

The shuttle rode on the side of the stack for a reason - so it could use it's three main engines for the entire climb to orbit. These engines were designed to be the best rocket engines ever developed (which meant they'd be very complex and expensive) and, therefore, to be re-usable. They were on the back of the orbiter not as an error, but precisely because that meant they would come home for re-use instead of being thrown-away on each flight. What you seem to think was a mistake, was in fact a design feature and part of the argument for making the scheme both technically and financially workable. As long as going to space requires throwing away most of the vehicle, it will remain the exclusive domain of governments and rich businesses/businessmen. Nobody but the super rich could afford to fly from NY to LA if the entire airliner was discarded during the flight and the passenger parachuted onto the LA runway in a small escape pod.
In actual practice, nothing about the shuttle system turned out to be as cheap as initially intended; that rarely happens on the first-generation of any world-leading technology. Had we built a 2nd generation of shuttles they likely would have performed far better with lower turn-around times and costs.

The Shuttle was a MANNED vehicle while the USAF's is NOT manned. Having a crew requires significant amount of equipment and weight to provide the minimum of life support (power, air, light, cooling, food, waste processing etc) which is not required by the USAF's unmanned drone. Further, it's been a couple of decades since the shuttle was designed and technology has advanced, getting smaller, lighter, and less power hungry. I am not surprised that an unmanned vehicle is smaller, cheaper, and more mission capable all things being equal. But they are not equal..
Comparing the current state of the art and complaining that what we fielded 30 years ago was a waste is not valid. Yes, the Shuttle did not meet the cost per launch targets, but I don't think the shuttle program was a total waste of time or money because of that. And the USAF's unnamed drone is 30 years more advanced in technology which was partially developed through what we learned though the shuttle program.
If anything surprises me is that it took so long for the USAF to figure out they needed a reusable platform of their own, but even that is understandable when you remember they used the shuttle for some classified work when it was available. This is just the natural progression of things.

Perhaps, but NASA has had major managment issues from the start. Go read Appendix D of the Challenger Disaster report, by one Mr. Feynman, who had to fight tooth and nail to expose the institutional problems that led to the problem. It's since become a case study in how not to manage a project and is required reading in several prominent engineering companies. The design of the shuttle engines, while amazing pieces of technology, were not built according to best practices -- it was literally put together as a whole system and then tested as a completed unit rather than integrating each subsystem after extensive testing and comparison with expected baseline. Debugging the damn thing was exceptionally problematic and to this day it's still not known if all the possible failure modes and bugs have been found and documented. Management showed a long pattern of decreasing safety standards and bypassing procedural safeguards to maintain their image as "cutting edge".
NASA still suffers from those problems today, and private contractors and now the USAF have proven that the technology is actually not all that sophisticated nor requiring the massive administrative overhead that is so typical of NASA missions and daily operations. They've done it faster, better, and cheaper than NASA did, and their success lies not in copying existing technology, or inventing new technology, but in having good project management skills and not letting committee thinking and politics mangle and derail the whole thing, leading to massive cost overruns.
