Associated Launch Vehicles
  • Trailblazer 1 American test vehicle. The rocket's first three stages would take the upper stage package to a 260 km apogee. The upper stage package was mounted upside-down in relation to the other stages. When it had reached the peak, the three upper stages fired in sequence, ramming the payload, a 13 cm sphere, into the atmosphere at orbital re-entry speeds. More...

Associated Propellants
  • Solid Solid propellants have the fuel and oxidiser embedded in a rubbery matrix. They were developed to a high degree of perfection in the United States in the 1950's and 1960's. In Russia, development was slower, due to a lack of technical leadership in the area and rail handling problems. Solid propellants have the fuel and oxidiser embedded in a rubbery matrix.
