American manned spacecraft module. Study 1961. The Service Module housed the fuel cells, environmental control, and other major equipment items required for the mission.
It also provided the propulsion requirements for lunar launch through transearth midcourse corrections. The same basic engine would used as on the terminal landing module with the throttling feature removed and a radiation cooled
skirt added to provide an expansion ratio of 40:1.

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...
