Engineers developed an engine prototype which could reach unprecedented speeds, cutting down interplanetary travel time.

In a Saturn V rocket engine, liquid oxygen and kerosene fuel are pumped separately into the engine at high pressure. They first travel through a pre-burner, which dumps exhaust into the air.
