This blog post examines why mechanical and aerospace engineering plays a core role in space launch vehicle development and exploration projects, exploring its reasons and importance.
Do you remember the Naro rocket launch failure in South Korea in June 2010? Just two minutes after leaving the launch site with a Korean satellite aboard a Russian launch vehicle, communication was lost. This failure followed the first attempt the year before, ultimately resulting in the second attempt also ending in failure. Lacking the technology to place an artificial satellite into orbit on our own, we paid a staggering 800 billion won in royalties to lease a launch vehicle from Russia. Yet, even this leased vehicle failed to achieve success.
Although the Naro launch failed, it represented a project concentrating the most advanced technology available. Sending a satellite into space requires the convergence of not just mechanical and aerospace engineering, but all engineering and scientific disciplines. Simply put, it involves mechanical and aerospace engineering for the Naro rocket’s body, engines, and launch propulsion systems; electrical and electronic engineering for various electrical and electronic equipment and precision control; materials engineering to develop new materials ensuring the Naro’s exterior withstands extreme conditions; and physics to analyze and calculate all possible phenomena. Space launch vehicles like Naro are born through the meticulous and precise design and manufacturing efforts of experts from these diverse fields.
Space development, in particular, has become a crucial field that determines a nation’s standing and future technological supremacy, extending far beyond mere scientific and technological advancement. The space race between the United States and the Soviet Union during the Cold War is a prime example; the technological achievements of that era laid the foundation for today’s space industry. Space exploration and launch vehicle development have now transformed into means for nations to secure economic and military superiority. Against this backdrop, the aerospace industry is evaluated not merely as a technical challenge, but as a driving force for national development.
Every project has a leader, whose role is to guide the appropriate harmony of each field and oversee the entire project. The Naro project was conducted under the leadership of Professor Kim Seung-jo, President of the Korea Aerospace Research Institute. Professor Kim Seung-jo, affiliated with the Department of Mechanical and Aerospace Engineering at Seoul National University, is considered the foremost expert in South Korea’s mechanical and aerospace field. While experts from all fields are important, a mechanical and aerospace expert was deemed best suited to oversee the project, hence his leadership role. It’s similar to how, in pizza, while cheese, toppings, and sauce are important, the core of the pizza is undeniably the crust (bread). Even looking solely at the Naro project, mechanical and aerospace engineering handled the most critical parts. The overall exterior design (body), the engine generating propulsion, and the propulsion system creating the thrust for launch form the major framework of the entire Naro rocket. Only when this framework is solidly completed can the work of adding the flesh proceed.
Leadership in aerospace engineering demands more than just technical knowledge; it involves the complex role of clearly defining the project’s direction and goals while fostering harmony among diverse teams. In this regard, mechanical and aerospace engineers are indispensable in space projects, serving as the project’s central pillar. For instance, Dr. Wernher von Braun, who led NASA’s Explorer launch project, was a mechanical and aerospace engineer. Similarly, Dr. Doug McQuistion, currently leading the Mars exploration project, is also a mechanical and aerospace engineer. This field holds such appeal because mechanical and aerospace engineers often occupy leadership positions in numerous space engineering projects, bearing the weighty responsibility of overseeing the entire endeavor.
The aerospace industry is a cutting-edge sector that can determine a nation’s competitiveness. Achieving outstanding results in this field requires continuous research and development, along with the cultivation of exceptional talent. Korea’s aerospace industry will continue to advance, and the day will come when we develop our own unique launch vehicles and satellites. I anticipate that someday, under the capable leadership of a skilled mechanical and aerospace engineer overseeing Korea’s aerospace industry, a space launch vehicle like the Naro, built solely with Korean technology, will soar into space.
What is the next goal in space development? Humanity has already moved beyond lunar exploration, setting its sights on Mars exploration and deep space exploration. The role of mechanical and aerospace engineering will become even more crucial in this process. As long-term goals emerge—sustainable technology development for human space exploration, space station construction, and Mars colonization—complex system design and operation requiring the convergence of diverse engineering disciplines become essential. This signifies that mechanical and aerospace engineers must play a leading role at the forefront of space development.
Korea is also aligning with this trend, establishing new space development plans and continuously expanding investment. For these efforts to bear fruit, talent in the field of mechanical and aerospace engineering must play a pivotal role. Space development is no longer a dream but a reality, and our generation will be the main actors in achieving it. We look forward to the day when Korea’s mechanical and aerospace engineering students will play a key role on the global stage of space development.
