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...

It is used for launches of unmanned government and commercial satellites into polar orbit and intercontinental ballistic missile test launches toward the Kwajalein Atoll. More...
  • Poker Flat Sounding rocket launch site. In use from 1969 to present. Poker Flat Rocket Range (PFRR) contains five major launch pads. Pads 1 and 2 each have a 7.5K launcher, pads 3 and 4 each contain 20K MRL launchers, and pad 5 contains a 4K twin boom launcher. Pad 3 is equipped with a moveable launcher enclosure which can be used to protect a rocket on pad 3 and workers from the severe winter weather. More...
