A few years ago, an American media outlet announced the initiation of the Asgardia nation-building project, an endeavor planning humanity's collective migration to outer space. Recently, Elon Musk, CEO of SpaceX, released an intriguing report entitled "Making Humanity a Multi-Planetary Species," aiming to develop related technologies. The idea of relocating human activities to planetary realms beyond Earth has long been the realm of science fiction. Yet, for those without specialized knowledge in space science, such narratives may have seemed merely amusing tales. Although it might still seem somewhat premature, various projects propelled by 21st-century innovations and advanced sciences suggest that humanity's steps toward the "space age" are gaining real momentum.
In a September interview, we met 27-year-old engineering scholar Kim Heon-joo, a Mechanical Engineer at NASA's Jet Propulsion Laboratory (JPL) Caltech Center. Although Kim has been with NASA for just over four years, he has been involved in significant projects, including the Mars 2020 mission and the Europa exploration. Aspiring to contribute to space development and industry startups, and ultimately committing to popularizing space, Kim Heon-joo—known as a ‘Golden Child’—possesses not only a keen intellect but also impressive skills, such as playing Chopin on the piano.
Q: How do you feel working at NASA, a government organization supported by people worldwide?
I generally view NASA as my workplace, but opportunities like this make me feel proud. (smiles)
Q: Could you briefly explain NASA?
Though I'm not entirely knowledgeable, NASA is the United States' government space agency. Initially, it started as NACA, a body focused on aviation weapon systems during World War I, later evolving into NASA, shifting focus on space technologies amid the Cold War. Besides its headquarters in Washington, D.C., it has various divisions nationwide, including JPL, where I work.
Q: What is JPL like, and what is the environment there?
JPL is a national research facility operated by Caltech, engaging in planetary exploration, astrophysics, earth science technology development, and deep space communication. Being situated within a university campus, it offers an academic and free-spirited atmosphere, unlike typical corporate environments. It emphasizes open discussions and collaborative project completion, maximizing individuals' potential.
Q: When did you come to the U.S., and what did you study in college? What motivated you to join NASA?
I came from Korea during the fifth grade, accompanying my expatriate parents. I have always been fascinated with machinery, building things, and space-related toys. Initially, I had a vague admiration for NASA. I pursued mechanical engineering and physics at U.C. Berkeley. Compared to other applicants, my qualifications might not have stood out, but luck favored me. NASA likely appreciated my involvement in various university projects.
Q: Could you outline your application and acceptance process at NASA?
As I was about to graduate, I applied during a campus recruitment event. NASA's team spent around a week at the university, collecting applications and conducting the first-round interviews of those passing the document screening. Following this, I received an invitation and airfare to participate in on-site interviews at NASA. The interview involved presenting practical problem-solving demonstrations with assessors participating and using various machine components to infer functions—a practical approach rather than mere theoretical assessment. I eventually received the final acceptance notification.
Q: What are the main projects at JPL you are involved with right now?
Our focus is on the Mars 2020 mission set to launch next year. The previous exploration in 2012 confirmed water on Mars. This time we aim to collect soil and rock samples and return them to Earth for precise study. We plan to gather 40 samples, aiming for a July 2020 launch, and we're 80% complete. The subsequent project involves Europa—Jupiter’s moon—given its water coverage, suggesting potential life.
Q: Can collecting 40 samples define Mars as an Earth alternative?
Selection of landing sites necessitates meticulous care, involving numerous scientists and engineers in thorough discussions and reviews. Prioritizing regions with high potential for past or current life is based on scientific rationale.
Q: What is your specific focus in the Mars 2020 project?
I am involved in the mechanisms related to storing and sealing the collected samples, as well as the spacecraft's structure. Additionally, I am tasked with test piloting the Mars Helicopter Scout assisting airborne exploration.
Q: Did you focus on particular studies for this career path? Any advice for young scientists?
NASA encompasses various scientific fields, so limiting oneself isn’t necessary. An expansive interest in sciences and various experiences are beneficial. Assuming proficiency in math and science, studying coding can be advantageous. In middle and high school, I enjoyed creating 3D models and robotics, believing that hands-on creation offers valuable learning.
Q: What has been your greatest motivator in achieving your goals?
My parents' unwavering support energized me, fostering my early interest in machinery and facilitating its pursuit.
Q: How do you spend your leisure time?
Previously, I avidly watched "Infinite Challenge," but now I miss it since it ended (laughs). I currently focus on exercising, gaming, and playing the piano. Individuals perceive ‘play’ differently, and I derive enjoyment and excitement from conceptualizing, designing, and materializing new ideas.
Q: How would you describe a 21st-century talent?
There's the specialist, someone with deep expertise, undeniably valuable to society. Conversely, there are those who, though perhaps lacking specialization, excel at integrating and managing a diverse team—a synergy of these attributes coupled with creativity and logical thinking defines a 21st-century talent.
Q: What future plans do you have in space exploration?
Assuming I continue at NASA, I intend to actively lead diverse projects. If venturing into startups, I’d like to democratize space benefits, making them accessible to more people. Space offers endless possibilities, yet access remains limited. Commercializing space benefits, making them universally available, and contributing positively to society would be immensely rewarding.
