Detailed explanation-1: -It is exactly 75 years since Dr Robert H. Goddard successfully launched the first liquid-fueled rocket on 16 March 1926. In his biography of Dr Goddard, Milton Lehman referred to this event as “a feat as epochal in history as that of the Wright brothers at Kitty Hawk".
Detailed explanation-2: -rocket. Image credit: U.S. Air Force. Goddard began experimenting with liquid-fueled rocket engines in September 1921, using gasoline as fuel and liquid oxygen as an oxidizer, successfully testing the first one a little more than two years later.
Detailed explanation-3: -Liquid fuel was also used for the massive Saturn V rocket that took astronauts to the moon in the 1960s and 1970s. Liquid remains the fuel type of choice for human missions to this day; because the burn can be controlled, it is safer than solid rocket propellants.
