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...
  • 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...
  • Wake Island US Pacific test vehicle launch site. In use from 1974 for launches of re-entry test vehicles and anti-ballistic missile targets. Known to have been used for 18 launches from 1974 to 2004, reaching up to 500 kilometers altitude. More...

Associated Stages
  • M56 Solid propellant rocket stage. Loaded/empty mass 5,170/466 kg. Thrust 228.40 kN. Vacuum specific impulse 297 seconds. Second stage of Minuteman I. Used as first stage of Aries sounding rocket and various SDI targets in 1980's. More...
  • Talos-1 Solid propellant rocket stage. Loaded mass 1,500 kg. Thrust 516.00 kN. The Talos motor was fitted with a conical adapter for mating to the second stage. Differential drag forces caused separation. Four fins were arranged at the aft end in a cruciform configuration and drove the vehicle to approximately one revolution per second burnout roll rate.
