I’m going to start writing about one of the key parts in any system that you need to send cargo or humans to space, the rocket, mainly its history, their origins, divided by organizations that built and/or operate it, and anything that I can add that I don't mention here.
A brief introduction here.
People may think that when someone talks about rockets, it means something related to wars, destruction, or even fireworks. They can mean any of those two, and also the ones used to escape the earth gravitational push and go into space!.
I will talk about the latter, which I think are the most exciting ones nowadays. Some of the space rockets started based on military models, ICBM (Intercontinental Ballistic Missile).
The firsts rockets...
The first rockets that we have knowledge of, where made by the Chinese by the 13th century, they were powered by gunpowder.
The name comes from the Italian word rocchetta (meaning "little spindle").
Modern rockets derive from the V2 rocket that began development in Germany. Later after the World War II, the Americans captured and recruited more than 1600 German scientists, engineers and technicians during Operation Paperclip, including the famous premier rockect scientist Wernher von Braun.
How they work?
They use the Newton's Third Law of Motion. This law says that for every action, there is an equal and opposite reaction. The rocket pushes on its exhaust, and the exhaust pushes the rocket back, simple as that.
So this is it, a little introduction to rockets, stay tuned for the following series of articles! :D
