Well, it looked spectacular.

I'm referring to NASA's recent launch of the Ares 1-X, billed as the prototype of the Ares 1 as a crew launch vehicle, a fancy term for a manned space booster. The rocket is said to have performed as planned, and ushered in the era of the Ares rockets to replace the Space Shuttle next year. Only it won't. In fact, the much-hyped Ares 1-X was much ado about nothing.

Yes, the rocket that thundered aloft from NASA's Launch Pad 39B sure looked like an Ares 1. But that's where the resemblance stops. Turns out the solid booster was - literally - bought from the Space Shuttle program, since a five-segment booster being designed for Ares wasn't ready. So they put a fake can on top of the four-segmented motor to look like the real thing. Since the real Ares' upper stage rocket engine, called the J-2X wasn't ready either, they mounted a fake upper stage. No Orion capsule was ready, so - you guessed it - they mounted a fake capsule with a real-looking but fake escape rocket that wouldn't have worked if the booster had failed. Since the guidance system for Ares wasn't ready either they went and bought a unit from the Atlas rocket program and used it instead. Oh yes, the parachutes to recover the booster were the real thing -- and one of the three failed, causing the booster to slam into the ocean too fast and banging the thing up. So, why you might ask, if the whole machine was a bit of slight-of-hand rocketry did NASA bother to spend almost half a billion dollars (that's billion with a "b") in developing and launching the Ares 1-X?

The answer: politics.

Technical problems, the kind that follow every new rocket's development, have haunted the Ares like leftovers from Halloween. The rocket as currently designed shakes so much during launch that shock absorbers are needed beneath its capsule payload. All of this takes time to fix -- and money, money that NASA really doesn't have. To stave off critics, three years ago the Project Constellation managers conceived of the 1-X flight to supposedly show some progress. They could instrument the rocket with hundreds of sensors gathering information never before obtained during a booster use in a Shuttle mission. It would give the launch team some practice in the assembly of an Ares. And NASA would find out if something as ungainly as the Ares 1 design - a thicker top than the bottom booster - could survive during ascent through the Earth's atmosphere. Of course, all of the changes to the Shuttle launch pad to accommodate the Ares wouldn't be ready in time, so they decided to just leave all of the Shuttle hardware, such as the rotating tower that envelops the Shuttles there. A success might just buy more time for Ares to fix its problems.

And that's just what happened.

2. Gee if we had enough small ones

I know the best place to put them. I like Buzz Aldrin also.
