William Hale
It worked by spin stabilization where the method exhaust gases struck small vanes at the bottom of the rocket which caused it to spin as much as a bullet does in flight. It was fueled by exhaust gas. -
Konstantin Tsiokovsky
It worked by using liquid propellants for rockets in order to achieve greater range. The speed and range of the rocket were limited only by exhaust velocity. It was fueled by liquid propellants. -
Robert H. Goddard
He used solid-propellant rockets. The various types of solid fuels burn gases. He used fuel and oxygen tanks, turbines, and combustion chambers. -
Space X
It is powered by rocket engines that burn liquid oxygen and rocket-grade kerosene propellants. It uses liquid fuel. -
Hermann Oberth
It worked by burning a mixture of liquid oxygen and alcohol at a rate of about one ton for every seven seconds. It led to the development of the V-2 rocket
