The first rockets were invented in China sometime between the 9th and 13th centuries (A.D). These were black powder rockets that were essentially what we would call fireworks today, but were technically what are known as solid fuel rockets.
The Rocket was designed and built by George Stephenson with the help of his son, Robert, and Henry Booth, for the 1829 Rainhill Trials.uring the race, the Rocket reached speeds of 24mph during the 20 laps of the course. This was due to several new design features. It was the first locomotive to have a multi-tube boiler-with 25 copper tubes rather than a single flue or twin flue.
