Hello! Welcome to my channel. Hope you'll find this channel informative, interesting and helpful. In the meanwhile, here are some fun facts about rocket.

Rocket Fun Facts
----------------------------

1. NASA has launched a total of 166 manned rockets to space missions.

2. Rockets have been used in space travel for over 70 years.

3. NASA rockets cost $500 million to build and launch.

4. China has launched more rockets than any country in the world.

5. There are 4 types of rockets: solid-fuel, liquid fuel, ion, and plasma rockets.

6. 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.

7. 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.

8. The largest rocket is over 300 feet tall.
Standing at 363 feet tall with a thrust of 7.6 million pounds, NASA’s Saturn 5 rocket is the largest one to date. The Saturn 5 was used for Lunar missions between the 1960s and early 1970s.

9. Rockets launch in 3 stages.
Rockets aren’t one solid hunk of metal. If you’ve ever seen a rocket in space on cartoons or TV shows, you’d notice how it breaks apart. Essentially, a rocket breaks off into sections while in flight. The first stage of a rocket launch is ignition. From takeoff, the burning rocket exhaust will push the rocket forward. Once the fuel runs out, the section will break off. From there, the second stage fuel reserve will be used until the payload reaches orbit.

10. Rockets are loud.
Rocket sound is so loud, it can destroy the rocket. When a space rocket is launched, acoustic waves can generate up to 180db of sound – which is almost as loud as a nuclear explosion. To avoid this, a sound suppressor system is built into the launch pad. The system uses water to absorb the sound waves from the rocket as it launches.


11. Liquid-fuel rockets are more powerful than solid-fuel rockets.
Solid-fuel rockets were invented first in 13th century China. However, it was liquid-fuel rockets that eventually paved the way for space travel. Liquid-fuel rockets are equipped with more reactive oxidizers, causing a stronger chemical reaction and stronger propulsion. To escape Earth’s gravity, spacecraft must travel 4.9 miles per second – which is almost the speed of the world’s fastest production sports car.

12. The Saturn V rockets were the most successful rockets ever launched.
Not only is it the biggest rocket, but it is also the most successful one with 13 completed launches. Currently, at least two Saturn V stages from the Apollo missions are still in space. NASA is still tracking them as Near-Earth Objects.
