A cryogenic solid hybrid engine with a solid propellant chamber, a first propellant within such chamber in which the first propellant is in solid form in the chamber and is in fluid form at room temperature, a coolant fluid chamber and a coolant fluid in the coolant fluid chamber being maintained at a temperature blow the freezing point of the first propellant. The invention also relates to a method for propelling a rocket and a method for forming a solid propellant grain for use in a cryogenic solid hybrid rocket engine.
