If you've been to any of the nighttime observing sessions at our Public Observatory, you might have wondered why we mostly view the planets and the Moon. After all, the Observatory houses a professional 16-inch telescope, and several other high-quality portable telescopes; shouldn't they be able to show us great views of galaxies or nebulas? They should, and they could, if they were located at what astronomers call a "dark site" — away from the city lights that often outshine the lovely stars of nighttime.
For those of us who study the very early history of the airplane, the sight and sound of a World War I rotary engine running is a thrill that leaves a lasting impression. To fly in a rotary powered World War I airplane is a transformative experience.
During the recently completed centennial of naval aviation (2011), there were many and varied tributes to the factual history of naval aviation. Nevertheless, we cannot forget that public perception of the armed forces is also a strong historical consideration.
After pressing some buttons to start up the ascent engine of their lunar module Challenger, astronauts Gene Cernan and Harrison Schmitt left the Moon on December 14, 1972.

Twenty-five years ago, the staff of the National Air and Space Museum held its collective breath for nine days as a seemingly fragile, flying fuel tank made its way across oceans and continents in an attempt to become the first aircraft to fly around the world non-stop and unrefueled.
The American flag is one of the most important symbols of the United States. For many, it symbolizes respect, honor, and freedom. For others, the flag represents reflection, courage and sorrow.
Airplane designers will tell you that the wing is the heart of an airplane. For conventional airplanes, it provides most of the lift generated by the airplane; the fuselage and tail contribute only a few percent of the overall lift of the airplane.
The first mass-produced toy ray gun had boys and girls flocking to department stores. Do you remember the first space-related toy you ever received?
These suits have come a long way. True, it’s only 37 miles from Suitland, Maryland to Chantilly, VA. On a good day, that’s less than an hour’s drive on the beltway. But today, like 42 years ago, these suits are worlds away from where they came.
