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...

1963 July 20 - . 05:44 GMT - . Launch Site: Wallops Island. Launch Complex: Wallops Island LA3. LV Family: Scout. Launch Vehicle: Scout X-3A. LV Configuration: Scout X-3A S110. FAILURE: Failure..
  • Reentry 3 re-entry vehicle test flight - . Nation: USA. Agency: NASA. Apogee: 2.00 km (1.20 mi). NASA launched a Scout rocket with a nose cone of experimental heatshield material from Wallops Island, Va. The rocket was intentionally destroyed when it deviated from its course a few seconds after liftoff. The nose cone had been expected to reenter the atmosphere at 27,934 kilometers (18,600 miles) per hour to test the material's thermal performance under heating loads near those of a lunar reentry.
