5 Subjects You Must be Good at If You Want to Study Rocket Science

Studying rocket science is not for the faint of heart. After all, it is a multidimensional field that demands a solid foundation in various subjects to comprehend the intricacies of space exploration. 

Of course, the returns and perks that come from this line of work are really good. According to Salary.com, rocket scientists earn between $92,353 and $118,754 per year in the US. Plus, there’s the thrill of working with rockets, something that not everyone gets to experience.  

Before all that, aspiring rocket scientists must hone their skills in a range of disciplines. In this article, we explore some of these disciplines or subjects that are imperative for anyone looking to study rocket science.

#1 Mathematics

At the heart of rocket science lies the language of the universe – mathematics. A profound understanding of calculus, differential equations, linear algebra, and advanced trigonometry is essential for solving the intricate problems encountered in space exploration. 

From trajectory calculations to orbital mechanics, rocket scientists rely heavily on mathematical models to predict and analyze the behavior of spacecraft. Mastering these mathematical concepts not only facilitates problem-solving but also enables engineers to design efficient propulsion systems and plan precise space missions.

However, honing one’s math skills is easier said than done. In fact, according to a study published in the Journal of Educational Psychology, even kids with strong math skills can struggle in the subject. Therefore, those who actually plan on pursuing rocket science must be mentally strong to overcome their fear of mathematics. 

#2 Aerospace Engineering

Rocket science is inherently intertwined with aerospace engineering, a specialized branch that focuses on the design, development, and testing of aircraft and spacecraft. Aerospace engineers delve into subjects like aerodynamics, materials science, structural analysis, and control systems. 

A strong understanding of aerodynamics is vital for designing rockets that can traverse the Earth’s atmosphere and navigate through the vacuum of space. Material science ensures the construction of spacecraft that can withstand the harsh conditions of space, while structural analysis guarantees the integrity of the vehicle. Control systems are crucial for ensuring the stability and maneuverability of rockets during flight.

According to Times Higher Education, an aerospace engineering degree can take between three and five years to complete. Patience is key when pursuing an aerospace engineering degree, as the field’s topics tend to get more and more difficult over time. 

#3 Physics

A comprehensive grasp of mechanics, thermodynamics, and fluid dynamics is imperative for developing propulsion systems and understanding the behavior of spacecraft in various environments. Newton’s laws of motion become guiding principles for engineers designing rockets, while thermodynamics plays a pivotal role in developing efficient engines. At the same time, fluid dynamics is crucial for analyzing the flow of propellants and gasses within rocket engines. 

A solid foundation in physics allows aspiring rocket scientists to conceptualize, design, and optimize the performance of space vehicles.

#4 Chemistry

Chemistry is a fundamental subject for rocket scientists, particularly in the context of propellant formulation and combustion processes. Propellants, the substances used to generate thrust in rocket engines, undergo complex chemical reactions during combustion.

A deep understanding of chemical kinetics, thermodynamics, and combustion theory is crucial for designing propellants that maximize efficiency and minimize environmental impact. Engineers need to balance factors such as energy content, stability, and combustion products to create propellants that meet the demanding requirements of space travel.

Chemistry is also important for understanding how rocket fuel is made and how it works. For instance, oxygen difluoride (OF2 ) is used in rocket fuel as an oxidizer. According to Proprep, this chemical compound has one oxygen atom, two fluorine atoms, and a bond angle of 109°27′. The oxygen component in this compound is what mostly takes care of the oxidizing part.

When studying all this, you have to cover topics including the OF2 Lewis structure, how oxidation starts, when it’s needed, and so on. A solid grasp of chemistry is a must if you want to tackle these delicate but super-important topics in rocket science. 

#5 Computer Science

In modern space exploration, computer science has become indispensable for rocket scientists. Computer simulations and modeling play a pivotal role in designing and testing spacecraft components and systems. Programming skills are essential for developing simulation software, numerical analysis tools, and control algorithms.

Besides, computer science is integral to the operation of spacecraft, as it involves the programming of onboard systems, data analysis, and communication protocols. A strong foundation in computer science empowers rocket scientists to leverage cutting-edge technology for the advancement of space exploration.

In conclusion, when it comes to studying rocket science, mastery of a diverse range of subjects is not merely a suggestion but a necessity. The multidisciplinary nature of space exploration demands a holistic approach to education and training.

Aspiring rocket scientists must cultivate a deep understanding of the subjects discussed above to navigate the complexities of designing, launching, and operating spacecraft. Only by integrating these diverse disciplines can individuals hope to contribute meaningfully to the ever-expanding frontier of space exploration.
