  • Europa European orbital launch vehicle. Europe's first space launcher. The first stage was a British Blue Streak IRBM, the second stage the French Coralie, and the third stage the German Astris. All orbital launch attempts failed due to unreliability of the third stage. The project was cancelled after withdrawal of British support and replaced by the Ariane. More...

Associated Propellants
  • N2O4/UDMH Nitrogen tetroxide became the storable liquid propellant of choice from the late 1950's. Unsymmetrical Dimethylhydrazine ((CH3)2NNH2) became the storable liquid fuel of choice by the mid-1950's. Development of UDMH in the Soviet Union began in 1949. It is used in virtually all storable liquid rocket engines except for some orbital manoeuvring engines in the United States, where MMH has been preferred due to a slightly higher density and performance.
