A NASA rover launched from Earth six months ago to collect rock
core samples on Mars will
make landing on a dry lakebed on the red planet this afternoon.
The Perseverance Rover the fifth robot NASA has launched
since 1997 as part of a larger mission to understand whether life
exists on Mars has a name that holds significance for both
the pandemic launch, and also for team members like Aaron
Yazzie (Diné), one of just a handful of Native Americans
working on the project.
The car-size Perseverance
Rover will extract rock samples from Jezero Crater over the
next two years. Yazzie, a mechanical engineer at the NASA Jet Propulsion
Laboratory in Pasadena, Calif., told Native News Online that when
a meteorite hit the planet 3.5 billion years ago, there was a lake
in the crater, meaning that core rock samples are likely to hold
ancient rock information.
"Because Mars and Earth are rocky, terrestrial planets, they both
developed over billions of years in a similar way," he said. "But
at the same time, if we know that Mars and Earth have developed
similarly over so long, then why do we look like we do, and they
look different? And also, is there a possibility that life could
have formed there just like life forms on Earth? It's a very plausible
question that it's going to be really exciting to to find out the
answer to."
The $2.7 billion mission, which blasted off from Cape Canaveral,
Fla., on July 30, was named by a school kid in a competition just
weeks before Covid-19 shut down the nation. That namesake soon became
a reality for the hundreds of employees scrambling to ready the
mission.
"I can tell you, this is not what scientists usually do,"
Ken Farley, Perseverance project scientist at the California Institute
of Technology, said during a press conference. "Scientists do not
usually perform under these kinds of circumstances."

For Yazzie, Perseverance represents something more than remote
work, plus the five years he spent on the project developing the
rover's drill, which will carve out Mars rock. It also represents
his ancestral journey from the Navajo Nation to, now, space.
Yazzie grew up in the painted desert just outside of the Navajo
region in northern Arizona. As a kid, he would play on the mesas
in the reservation, kicking up red dust with his cousins.
"If you took a picture of us way back when playing on those foothills
and mesas and sand desert and everything, it looks like we're playing
on Mars," Yazzie said.
His parents were the first in their families to attend elementary
school, where they learned English, and then eventually go on to
earn college degrees. "I was able to start on their shoulders and
move on from there to get this amazing career," he said. "So perseverance
is an excellent theme, not only for me, but for my entire history,
my family's history, my peoples' history."
Yazzie indirectly began his journey to NASA in high school.
He got involved with the American Indian Science and Engineering
Society (AISES), an organization that aims to increase Indigenous
representation in science, technology, engineering and mathematics
(STEM). Yazzie participated in various internships at NASA, and
eventually attended Stanford University for his undergraduate degree.
"People often ask me, did I always know that I wanted to work at
NASA when I was a kid? And the answer was no, I never even considered
it as something that was available to me or possible for me in my
future," he said. "As a Native engineer working in the STEM field,
you can feel like you're the only one who is like you from your
background."
According to a 2015 report by the National Action Council for Minorities
in Engineering, although Native Americans and Alaska Natives make
up 1.2 percent of the total population, they represent just 0.4
percent of all engineering bachelor's degree recipients, and 0.3
percent of the engineering workforce.
But, as the Smithsonian
points out, "Indigenous Peoples of the Americas have always been
accomplished scientists and innovators in ways that value balance
and unity with the environment."
For Yazzie, that has meant pursuing origin stories ingrained in
him from childhood. Navajo children are told stories of how land
forms and how constellations in the sky came to be in order to better
understand their identity and their connection to the land, he said.
"It's very important for us to understand where we came from, and
our origins," Yazzie said. "When I'm doing this work for NASA, it
feels like a similar goal, like I'm trying to find the origins of
a rocky planet and understand how life might have formed over billions
of years ago."
He encourages Native youth to pursue big dreams by taking advantage
of small opportunities, like internships and summer programs.
"If they really want to do something big, like work at NASA one
day, they can do it," he said. "They're capable, and that they can
do it if they want to."
