Associated Launch Vehicles
  • Vanguard American orbital launch vehicle. Vanguard was the 'civilian' vehicle developed by the US Navy to launch America's first satellite as part of the International Geophysical Year. The Army / von Braun Jupiter-C instead launched the first US satellite after Sputnik and Vanguard's public launch failure. The second stage design led to the Able upper stage for Thor/Atlas, and then to the Delta upper stage still in use in the 21st Century. The original version of Vanguard used a Grand Central final stage. 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.
