Navajo Roots Trailblaze a Path to Mars

Aaron Yazzie continues to set his sights higher at NASA’s Jet Propulsion Laboratory. With a Diné (Navajo) background, he earned his Bachelor of Science in Mechanical Engineering from Stanford University, and as a Mechanical Engineer with a focus on Sample Acquisition and Handling at NASA, Yazzie designs mechanisms for acquiring geological samples from other planets.
Diversity in STEAM Magazine had a chance to talk with Yazzie about his Native American background and how it influenced his journey to NASA.
DISM: Can you tell us about your background and journey to becoming a mechanical engineer at NASA?
Yazzie: I was born in Tuba City, Arizona, on the Navajo Reservation. I was born to parents who were 1st generation college students in their families—families that have had traditional Diné upbringings. Their first language was Dinébizaad (Navajo Language), their first known homes were our traditional Diné Hooghan (Navajo Hogan Houses/Dwellings). They learned the English language in elementary school, where they were the first generation in their family forced to attend school by the US government. From that unique beginning, and from that early-childhood culture shock and trauma, both my mother and father made it through an educational system rigged against them, graduated high school, and went to college—the first in their families. My mother earned her degree in education—she became a high school level math teacher. And my father received a degree in civil engineering—he became an engineer for the Arizona Department of Transportation. Both of them have been pioneers of Indigenous achievement in higher education and STEM careers. They may not be known and recognized by the larger Native community as STEM pioneers, but they are certainly my inspiration and the trailblazers to my career at NASA.
I grew up in Holbrook, AZ, a small border town to the Navajo Reservation. My brothers and I grew up, and attended school in the Holbrook School District, where we all graduated proud “Holbrook Roadrunners.”
Growing up, I didn’t have any examples or role models who went to prestigious private schools or went on to work at places like NASA. I knew I wanted to transcend the expectations of my family and my hometown, which is why I always strove for the highest grades in school, participated in all the school leadership positions and sought out all the high school summer enrichment programs. These are the programs that ended up transforming me from a self-doubting minority student into a solid college applicant with some awareness of my self-worth. They gave me the confidence to apply to, and to eventually be accepted to, Stanford University—an event that changed the course of my life.
Making the transition from small-town public school to prestigious private college was a big challenge. Nothing about my time at Stanford was easy, whether it was the rigorous academics or the constant financial struggle. Not to mention being separated from a tight-knit home community like the Navajo community for the first time. I was forced to learn quickly how to adapt, persevere, and overcome many challenges during my time at Stanford. Thankfully, there was a supportive community of BIPOC students who were going through the same challenges as I was. We all supported each other and made it through—not only graduating, but each of us moving on to do incredible things.
I was hired by NASA Jet Propulsion Laboratory mid-way through my senior year at Stanford. I was heavily involved with the American Indian Science and Engineering Society from the time that I was a high school freshman. I grew from there to be president of my high school AISES chapter, then became the Stanford AISES chapter president, and then National AISES Region 2 Student Representative. Along the way I received a 4-year scholarship from AISES to attend Stanford, and while there, I received 2 NASA internships through AISES. One placed me at NASA Goddard Space Flight Center and one at NASA Glenn Research Center. By the time I was ready to look for a job, AISES had helped give me a college education, 2 NASA internships, and a job opportunity with one of the most prestigious engineering institutions in the world. I met the NASA Jet Propulsion Laboratory recruiter at the AISES National Conference in 2007. From that interaction, I received an on-lab interview, and was hired soon after. I have been working as a Mechanical Engineer at NASA JPL for 12 years and counting.
DISM: Tell us about your significant milestone – when NASA’s InSight lander touched the surface of Mars. What were you feeling, and how was that experience?
Yazzie: NASA InSight was the first mission I worked on where I was tasked with leading the design and delivery of space flight hardware. Up until this point in my career, I supported missions as a test engineer or support engineer. When InSight successfully launched into space, it was the first time something I designed—something I touched with my own hands—went into space. And when it landed on Mars, it was the first time I sent something to another planet. I was completely thrilled, and overwhelmed with emotions when I saw the first set of pictures of my hardware on Mars. Considering where I came from, this achievement was monumental!
Being an engineer from a remarkably underrepresented community in STEM fields, it is a constant struggle to overcome imposter syndrome. I did not think I was a thriving or even adequate engineer at NASA. It’s a shame that it took an achievement like sending something to Mars to convince me that I belonged in my field, and that I belonged at NASA.
DISM: Can you tell us more about “Mars 2020”? What is the mission? How has the experience been?
Yazzie: Currently, I am the lead engineer for the Mars 2020 Drill Bits. We are sending the Mars 2020 Rover “Perseverance” to drill rock samples and save them in hermetically sealed tubes, so that we can eventually bring those samples back to Earth in future missions to determine if life exists on Mars. Additionally, this mission will study the history of rocky planets and conduct experiments that will pave the way for humans to travel to Mars. It’s really incredible to be part of another historic NASA mission. I’ve grown so much as an engineer—now sending my second flight hardware to Mars, but also being able to lead a team and be a mentor for the first time in my career. I’m very proud to have successfully delivered my parts to the rover, and very excited for the Mars 2020 launch in July 2020.
DISM: How has your Navajo background influenced your career?
Yazzie: Coming from an Indigenous background, I have a deep appreciation for the advancements of my family and ancestors before me. Considering that Native Americans weren’t granted basic civil rights in this country until 1968, it is remarkable that our people have not only overcome this historic oppression, but have been able to thrive and advance. I reflect on my own family, where as recent as one generation ago, my parents spoke no English, but learned in a small amount of time that education was the modern way to advance their people. My own academic achievements and this career I have been fortunate to achieve has all been made possible by the advancements of the Navajo people who have come before me. And it is for them that I use my privilege and platform to continue on.
DISM: What advice would you give to Native Americans wanting to pursue engineering?
Yazzie: Be resilient. It’s almost guaranteed that along your STEM journey, you will look around and not see very many others like you, from backgrounds like your own. But please understand that there are people in all directions of your life that are there to help you. Those before you, who want to help you succeed through mentorship and wisdom. Those beside you, who are on your same journey. And those behind you, who see you as an inspiration and role model. Recognizing that you have a full circle of support and inspiration will help you achieve any and all of your goals.
