  • Gemini American manned spacecraft. 12 launches, 1964.04.08 (Gemini 1) to 1966.11.11 (Gemini 12). It was obvious to NASA that there was a big gap of three to four years between the last Mercury flight and the first scheduled Apollo flight. More...

Associated Propellants
  • N2O4/MMH Nitrogen tetroxide became the storable liquid propellant of choice from the late 1950's. Monomethylhydrazine (CH3NHNH2) is a storable liquid fuel that found favour in the United States for use in orbital spacecraft engines. Its advantages in comparison to UDMH are higher density and slightly higher performance. More...
