Hello ladies and gents this is the Viking telling you that today we are talking about
Rocket Facts
From going distances that humans can’t reach to ensuring our safety, rockets improve our lives in more ways than you might think. Sit back and count down to these rocket facts that’ll make you realize the science behind these projectiles.
01 The term rocket comes from the Italian rocchetta, which translates to “bobbin” or “little spindle.”
02 The Chinese were experimenting with rocket mechanisms as early as 995 AD in the Song dynasty.
03 The 4 main parts of a rocket are the nose cone, fins, rocket body, and engine.
04 The cargo on a rocket is called the payload.
05 A rocket must travel at 7 miles per second to escape the Earth’s gravity.
06 Astronautics is the study of rocket science.
07 Solid-fuel rockets were the first large-scale rockets.
08 Robert H. Goddard is known as the father of modern rocketry, inventing the more powerful liquid-fuel rockets.
09 Ion rockets use electrical energy from solar cells.
10 Plasma rockets are still in development. They are powered through stripping negative electrons from hydrogen atoms
A rocket ship beats the vacuum of space.
Space is a giant vacuum with no air or atmosphere. Spacecraft can move through the vacuum through its engines. Rocket engines work through a chemical reaction that pushes it forward. The resulting rocket exhaust is expelled in the opposite direction of the ship at high speeds. This enables the ship to navigate and sustain its trajectory through space. That’s definitely one of the rocket facts to keep in mind.
Rockets were first used as weapons.
During the war between the Chinese empire and Mongol invaders, the Chinese devised a gunpowder-fueled arrow. The retreating Mongols described these projectiles as “arrows of flying fire.” These fire-arrows were the first solid-propellant rockets. From there, further experiments with cased gunpowder led to the development of military rockets and missiles.
You can make a rocket at home.
Learning how to build a rocket can help you understand the science behind it better. You may not believe it, but you can build a simple rocket out of random stuff lying around your house. With paper and a fizzy tablet, you can demonstrate the mechanism and principles of a rocket.
Rocket power is measured in thrust.
Rockets are self-propelling projectiles. Using up the fuel in the body, the rocket exhaust keeps it moving in the same trajectory. The force inside a rocket’s engine is called thrust. Since rockets weigh millions of kilograms, they must exert the same amount of force to propel itself through and out of the atmosphere.
The first rocket in space was launched by Germany in 1942.
Germany launched the first rocket capable of reaching space in 1942. Dubbed the V-2 rocket, it was not actually intended for space travel. Instead, the V-2 was constructed as a ballistic missile during WWII. Nonetheless, it was revealed in a flight test to be the first man-made object to fly into space.
The first rocket was invented in China around 1100 AD
The rockets invented in the 10th century China used solid propellants and were mainly used as weapons and fireworks. It was not until the 1920s that rocket science was studied further. By the 1930s and 1940s, professional rocket engineering started to take off.
And as always have a chilled day from the Viking
