  • Lox/Gasoline Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. Gasoline of various grades were used as fuel in the earliest rocket engines of Goddard and others. Once appropriate blends of kerosene were developed in the United States and Soviet Union, that became the hydrocarbon fuel of choice. More...
