On December 18 ,1958, America launched a rocket that broadcasted a Christmas message from space The message was recorded by Dwight D. Eisenhower, who was the president of the United States at the time. The mission was considered a great success, as it launched the first ever communications satellite into orbit, and laid the foundation for what is now an essential multi-billion dollar industry today. The communication satellite used to broadcast the Christmas message came to be known as the "talking Atlas”, as it was launched aboard an Atlas rocket. A rocket is exactly what you think it is - a long, thin metallic cylinder with a pointed nose that shoots up from the ground, leaving a gigantic cloud of smoke in its wake. However, there is more to it than that; there are a number of other things that make a rocket functional and useful. The word ‘rocket’ can mean different things in different contexts. Simply put, a rocket is a spacecraft, missile, aircraft or other vehicle that obtains thrust from a rocket engine. From the outside, the frame of a rocket is very similar to that of an airplane. It's made of various light, but very strong materials, like aluminum and titanium. The ‘skin’ of the rocket is covered with a thermal protection system that protects the rocket from extreme heat caused by air friction and helps maintain cold temperatures that are needed for certain fuels and oxidizers within the rocket. The body of a rocket is composed of different sections, all of which are housed within the frame of the rocket. The first component is the payload system of the rocket. For the uninitiated, the payload is the rocket’s carrying capacity. The payload depends on the type of mission the rocket is being used for - it can consist of cargo, a satellite, a space probe and even a spacecraft carrying humans. So, if you want to send humans to space, the payload of your rocket will contain a spacecraft, whereas if you’re using the rocket as a weapon, then the payload would consist of a missile. Next is the guidance system - the system which ensures that the rocket stays on its intended trajectory and goes where it's supposed to go. The guidance system consists of onboard computers and sophisticated sensors, as well as radar and communication systems to maneuver the rocket while in flight. Last is the propulsion system. A majority of the entire length of a modern rocket is actually made up of the propulsion system. As the name suggests, the propulsion system consists of the components that help launch the rocket off the ground, and subsequently propel the rocket in a given direction. So, how is this huge, **enormously** heavy, cylindrical metallic tube shot into space? In order to get into space, the rocket must first cross the thick layers of atmosphere that envelop the planet. Since the atmosphere is thickest near the ground, the rocket has to go **extremely** fast in order to get past this part of the atmosphere. So how does it climb so fast in the air?...
