Mind Exploding Facts About Rocket Science


How well do you understand rocket science? Well, fear no more: here are 24 bite-sized facts about an astronomically difficult science.


1. What Is a Rocket Anyway?

In its simplest form, a rocket is simply a chamber using pressure to enclose a gas. In this train of thought, a balloon is actually a rocket. Though there is a bit of variation, a modern rocket is typically a tube-like stack of components which carry propellants—fuel and an oxidizer—and one or more engines equipped with stabilization devices and a nozzle for acceleration and expansion of gases. So simple.

2. Back to Ancient China

The first development of rockets was by the Chinese in 1232 AD, when they used gunpowder projectiles in battle. However, there is evidence that suggests they were experimenting with these prototypical rockets as far back as 995 AD.

3.  Ah, Colonization

The use of metallic cylinder rocket artillery came along in 1792, when the rulers of Mysore in India developed the technology. After they were defeated by the British, the British took these developments and expanded them further into the 19th century.

4. Life Beyond the End

JPL continued operations following Parsons' departure, and after the development of the Explorer 1 satellite, that marked the beginning of America's involvement in the Space Race with the Soviet Union, it was incorporated into the National Aeronautics and Space Administration.

5. The Explorer

Explorer 1 was sent into space in 1958, and remained there until 1970. It had a mass of only 13.37 kilograms. This weight was very light compared to the Soviets' first satellite, Sputnik, which was 83.6 kg. Explorer was fitted with a Cosmic-ray detector and a Micrometeorite detector.

6. Exit Velocity

In order to be able to burst through the gravity of the Earth, a rocket needs to travel at a speed of 7 miles per second. Now, we’re not scientists ourselves, but it seems like that's pretty fast.

7. Sputnik!

Sputnik 1 preceded the launch of Explorer 1, and the Soviets actually got off a second rocket, the Sputnik 2, before the Americans achieved success with Explorer 1. Sputnik was originally launched on October 4th, 1957, and was a spherical object fitted with antennas, as opposed to the cylindrical shape of the Explorer.

8. Neighborhood #2

The Soviets launched Sputnik 2 only two months after Sputnik 1, but this time it carried a small dog by the name of Laika. Laika became the first animal to orbit Earth, but her lifespan was cut short as she didn't survive for long afterward. Some scientists were skeptical about a human’s ability to survive a launch, so animals were tested first. Because our lives matter more, of course.

9. We Gotta Do It

The Space Race got its start when Mstislav Kaldysh, Sergey Korolyov, and Mikhail Tikhonravov submitted a letter to the Soviet government proposing the development of an artificial satellite to orbit the Earth.

10. The Other Father

Robert H. Goddard is also sometimes considered the father of modern rocket science, as the scientist first flew a liquid propellant rocket in 1926, which turned out to be the progenitor of the Saturn V rocket that launched 43 years later.

11. Ending the Reign of a Tsar

In 1881, the history of rocket propulsion veered strangely when Nikolai Ivanovich Kibalchich, one of Russia’s rocket pioneers, participated in the fatal attack on Tsar Alexander II. As the primary explosive expert, Kibalchich launched four projectiles at the Tsar, resulting in his demise. The 27-year-old genius, in line for execution, continued to concentrate diligently on his mathematical equations while confined within the foreboding walls of his cell.

12. Hold Your Jets

The 111 meter tall Saturn V was developed particularly to launch the Apollo astronauts, and used 1.2 million liters of liquid oxygen to combust and produce 7.5 million pounds of thrust in order to launch itself.

13. Out Of Service

The lunar space station was split between Russians and Americans, and they got along great over the first few years. That is until the Russians' eating habits got in the way: Because of their diet, the Russians were prone to clogging the shared toilets, so the Americans banned them from their half of the station.

14. Commerical Space

SpaceX launched their first commercial prototype in 2010. Named Falcon 9, it orbited the Earth twice before landing in the Pacific Ocean.

15. Cheese in Space

On SpaceX’s first test launch, they secretly sent a wheel of cheese into orbit in honor of the Monty Python sketch where John Cleese tried to order cheese from a cheese shop that has no cheese.

16. Nazis At It Again

Germany was actually the first country to produce a rocket capable of crossing the boundary of space. The famed V2 rocket of WWII was a ballistic missile launched by the Nazis on England and Belgium.

17. Gravity’s Rainbow

The designer of the V2 ballistic missile was Wernher von Braun. After the conflict, he worked with NASA to build up their program and launch the United States into space. He would be the chief architect of the Saturn V.

18. Gravity

Modern rockets use both solid and liquid fuel types. Space shuttles are armed with two solid fuel boosters and three liquid fuel engines for propulsion—since what complicates launching anything from Earth's surface is the persistent force of gravity here.

19. Mission to Mars

The world’s next venture into space is developing the Heavy-lift launch vehicle, which is a vehicle with the capacity to carry massive payloads and large amounts of people into space economically and efficiently. With the development of heavy-lift launch vehicles, interplanetary exploration will be more of a reality than it is today.

20. Super Chill

The most advanced countries in terms of rocket technology use Cryogenic fuel technology. That means that the propellants in rockets are supercooled, so this way H2 and O2 can be used as fuel and oxidizer.

21. New Fuel

The newest fuel technology being researched is Ion propulsion, which, obviously, uses ions to propel the spacecraft. This is believed to be one of the keys of interstellar travel, as it uses free ions and protons, ejected at extremely high speeds, to create thrust. This is based on Newton's third law of motion, which, simply put, is that for every action there is always an opposite, equal reaction.

22. Increasing Launches

There have been over 5,000 rocket or satellite launches across the world up to now, with over 500 of them coming out of NASA’s Cape Canaveral.

23. Hey Jack

Jack Parsons was one of the founding members of the Jet Propulsion Lab and is still known today as the “Father of Modern Rocket Science,” but he was also famous for his dark personal life, and he would eventually be fired from the Jet Propulsion Lab for unsafe behavior and due to pressure from outside investors. Not long after departing from JPL, he would tragically lose his life at the young age of 37 due to an explosion in his home laboratory.

24. A “Quirky” Guy

By day Parsons was developing modern rocket science, but by night he was an occultist, being mentored by none other than Aleister Crowley; he converted to Thelema, Crowley’s religious movement, in 1939. Due to his involvement with occultism, Parsons was accused of espionage during the era of McCarthyism, another factor in his departure from JPL. But despite the many stories surrounding him, he is still remembered as the first to build a rocket engine using composite rocket propellant, as a pioneer in the advancement of both liquid-fuel and solid-fuel rockets, and as an advocate of space exploration and human endeavors of spaceflight.
