  • 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/Aerozine-50 Nitrogen tetroxide became the storable liquid propellant of choice from the late 1950's. Aerozine was a 50-50 mixture of hydrazine and UDMH developed for use in the Titan 2 missile. Copied in one Russian missile but otherwise straight UDMH used more commonly. Higher boiling point than UDMH. More...
