Associated Launch Sites
  • 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...
  • Eglin This US Air Force proving ground and missile test range, based in Valparaiso, Florida and extending over a vast expanse of the Gulf of Mexico, was founded in 1935, In early 1946 the First Experimental Guided Missiles Group was activated at Eglin. The highly-instrumented Eglin Gulf Test Range supported flight tests of Bomarc, Matador, Quail, and Hound Dog cruise missiles. Both the military and NASA used Eglin to support launch of sounding rockets in support of their programs. Eglin was known to have been used for 441 launches from 1959 to 1980, reaching up to 686 kilometers altitude. The actual number of missile tests was many times greater. More...

Associated Stages
  • HJ Nike-1 Solid propellant rocket stage. Loaded/empty mass 1,900/954 kg. Thrust 365.00 kN. Rocket motor originally developed for the Army Honest John tactical missile. In sounding rocket applications the interstage adapter was bolted to the front of the Taurus and consisted of a conical shaped adapter which slip-fit into the second stage nozzle, thus providing for drag separation at Taurus burnout. Each Taurus fin was 0.46 square meters in area. Normally, the fins were canted to provide a two revolutions per second spin rate at Taurus burnout. The weight of the booster system is 3005 pounds.

  • HJ Nike Nike-3 Solid propellant rocket stage. Loaded/empty mass 599/256 kg. Thrust 195.60 kN. Vacuum specific impulse 195 seconds. The average sea level thrust of the Nike rocket motor was 190.3 kN. The interstage adapter was bolted to the front of the Nike and consisted of a conical shaped adapter which slip-fit into the second stage nozzle, thus providing for drag separation at Nike burnout. Each Nike fin was 0.45 square meters in area. Normally, the fins were canted to provide a two revolutions per second spin rate at Nike burnout. More...
