  • Deacon The Deacon was an advanced solid rocket motor design cancelled at the end of World War II. In 1947 NACA began using reworked surplus motors to boost instrumented subscale aircraft models to speeds of up to Mach 4. They became a workhorse for the Agency's aerodynamic research, resulting in new production. Thousands were flown, until, by the end of the 1950's, supersonic wind tunnels took over the job. More...

Associated Launch Sites
  • Wallops Island Small NASA launch site for sounding rocket launches and occasional Scout launches to orbit. Air launches are conducted from the Drop Zone Wallops Island, 37.00 N 72.0 W. With the last orbital launch in 1985 and the decline in sounding rocket launches, Wallops fell into near-disuse as a launch center. Its fortunes revised with the establishment of Mid-Atlantic Regional Spaceport in 2005 and orbital launches resumed in 2010. More...
