That NASA is more than a space agency may come as a surprise to some. Aeronautics, the first A of the NASA acronym, has always been a part of the National Aeronautics and Space Administration, but against the headline exploits of rocket launches, Moon landings, Space Shuttle missions, and Mars rovers, aeronautics is easily lost in the shadows of NASAs marquee space programs. This relative obscurity belies what has been a remarkably creative, productive, and highly effective group of researchers who, at one time, even helped bring about the Space Age and invent a space agency. The list of accomplishments for NASAs first A is long, and this book goes a modest way toward sketching these developments. Aeronautics really might be called the other NASA, distinct in its charge, methodologies, and scale. Aeronautics research is not mission-oriented in the same way that going to the Moon or Mars is. It is interested in learning about physical phenomena, such as turbulence, and how to do something, such as quieting the noise of helicopter blades. |
