Aaron Yazzie was born on the Navajo Nation and grew up in Holbrook, Arizona, a town that borders the reservation.
As a kid, Yazzie said he never thought he would one day work for NASA.
鈥淭here just weren鈥檛 a lot of people that I knew in my community or my family that had gone down a path to get a job like this,鈥� he said. 鈥淏ut I knew I was good at building things and being creative. I think those things pushed me in a path toward engineering.鈥�
Now, Yazzie designs mechanical components for space robots, like drill bits for the current Mars rover. He鈥檚 also at the center of an unlikely collaboration between NASA and the Navajo Nation government.
The space agency is using the Navajo language, or Din茅 Bizaad, to name features on the surface of Mars, which Yazzie said is meaningful to him and his tribe but also totally coincidental.
He said NASA split up the area where the rover could possibly land on Mars into quadrants that are roughly one square mile, then they named them after different national parks and monuments across the U.S.
The robot just happened to touch down in the quadrant named after Canyon De Chelly National Monument, which is located on the Navajo Nation.
鈥淪o the science team, as soon as they landed in that quadrant, they were incredible in that they knew it could be an area that could be significant for us 鈥� us being Navajos,鈥� he said.
The team reached out to Yazzie, as well as Navajo tribal leaders, and asked them to come up with a list of names for features of scientific interest on Mars in their language. Scientists will use the names to refer to the features until they are replaced by official names assigned by the International Astronomical Union.
The list includes the Navajo words ts茅 艂ich铆铆, which means 鈥渞ed rock,鈥� and 蝉茅铆迟补丑, which means 鈥渁mongst the sand,鈥� along with phrases like ts茅w贸z铆 bee hazhmeezh, which means 鈥渞olling rows of pebbles, like waves.鈥�
鈥淭he thought was, 鈥業f a Navajo person was looking around on Mars, this is how they would describe things,鈥欌�� Yazzie explained.
He added suggestions like bidziil, which means 鈥渟trength鈥�, and ho艂 nil寞虂, which means 鈥渞espect鈥�, to the list. Perseverance, the name of the rover, was translated to 贬补鈥檃丑贸苍颈.
Yazzie said he suggested those words because, although they don鈥檛 relate directly to the landscape of Mars, this is a chance to encourage people to learn Navajo.
That hope is shared by Navajo Nation President Jonathan Nez, who is part of the collaboration.
鈥淲e hope that having our language used in the Perseverance mission will inspire more of our young Navajo people to understand the importance and the significance of learning our language,鈥� he said. 鈥淥ur words were used to help win World War II, and now we are helping to navigate and learn more about the planet Mars.鈥�
Although he鈥檚 not fluent in Navajo, Yazzie said the collaboration means a lot to him personally, because it鈥檚 bringing together his tribal identity and his work as an engineer.
鈥淢y two worlds, which I felt were so separate, are now overlapping in just the most beautiful way,鈥� he said. 鈥淚t鈥檚 something that I never thought I鈥檇 see in my career, or in my life.鈥�
Yazzie said he plans to speak to high school students on the Navajo Nation about the collaboration, in order to inspire them to learn their language and consider careers in science and engineering.
