New technology can be surprisingly inexpensive. In the U.S., the Pentagon and the intelligence community spend billions of taxpayer dollars pushing the envelope on creative new hardware and software concepts that may never emerge from behind the black curtain of secrecy. That is probably a good thing for bombs and bullets, but it keeps a lot of potential dual-use technology out of the economy. Fortunately, there are means for innovation at the other end of the funding scale that can drive economic growth with actual, and significant, return on investment.

A classified U.S. National Reconnaissance Office KH-11 “Keyhole” satellite was successfully launched into low Earth orbit from Vandenberg AFB, Calif., on Aug. 28 by a United Launch Alliance Delta IV Heavy.

Many of us have enjoyed spectacular video of rocket launches from the rocket's point of view, with the launch pad receding rapidly and strap-on boosters falling away as the black sky of space shows up around Earth's curve. The “RocketCam” videos are a staple on YouTube, but they have a value that far exceeds entertainment. In the high-stakes spaceflight business, video shots of rockets and other space hardware in action give engineers a much better view of system performance than even the most detailed numeric telemetry.

Young people seem to be getting the message that engineering offers opportunity: 84,000 U.S. students graduated from universities in 2012 with engineering degrees. That is up 12% from 73,000 just six years ago, according to the National Academies. And despite the downturn in the economy and in federal spending, the aerospace and defense industry continues to provide at least some of that opportunity.
