AAPI scientists and engineers are among NASA's Martians who worked on Preserverance's Mars landing

Peseverance will look for signs of life on Mars.

Hollywood's version of NASA is so different from reality. For an agency that has long been depicted in movies, TV shows and in its own landing broadcasts as being predominantly built by white men, the Perseverance control room provided a striking new look for the National Aeronautics Space Agency.

The U.S. landing a rover on Mars last week could not have happened without the AAPI scientists and rengineers who have worked on the project.

In recent years, NASA has come a long way from its first diverse class of astronauts in 1978. On Feb. 18, many in the team of engineers that guided Perseverance on its journey were women and people of color. And most have worked for a decade to pull it off.

Swati Mohan

It was hard to miss Swati Mohan, an Indian American scientist in the front row, with a bindi on her forehead, who became the face of the Mars mission. She was the scientist who exclaimed, "Touchdown confirmed!" when the rover landed on the red planet's surface.

Mohan has been part of the Mars 2020 mission since it began in 2013. She explained to viewers the rover's mission milestones. She was the guidance, navigation and controls operations lead.

"Perseverance will be the first mission to use Terrain-Relative Navigation,” Mohan explained to KRTV. “While it’s descending on the parachute, it will actually be taking images of the surface of Mars and determining where to go based on what it sees. This is finally like landing with your eyes open. Having this new technology really allows Perseverance to land in much more challenging terrain than Curiosity, or any previous Mars mission, could." 

Mohan is an aerospace engineer and the Guidance and Controls Operations Lead responsible for Perseverance. Mohan was tasked to ensure the spacecraft that carried the rover was properly oriented during its travel and upon its landing on Mars, according to her NASA profile. 

She has also worked as an engineer on multiple other NASA missions, to Saturn and the moon.

NASA recognizes the value of diversity. 

"Diversity is a hallmark of NASA – after all, we wouldn’t be the agency we are without it." Clayton Turner, the first Black director of NASA’s Langley Research Center in a  February statement

Still, NASA has catching up to do on diversity: Recent employment numbers show 72% of NASA employees are white, with 12% Black, 7% Asian American, 8% Latino and 1% American Indian. Meanwhile, only 34% of NASA employees are women.

Allen Chen

Also working at JPL alongside Mohan is Chinese American systems engineer Allen Chen, who is currently the Entry, Descent, and Landing (EDL) Lead for the Mars 2020 project. As part of his role in the project, he co-led the joint science/engineering Mars atmosphere characterization team.

According to his bio profile on NASA, Chen conducted a number of advanced studies looking at landing capabilities, including opportunities such as Mars Sample Return architectures. During a NASA media briefing last month, Chen explained that the spacecraft carrying the Perseverance rover will have to "slow from down to supersonic speeds using a 70-foot diameter parachute while still traveling at almost twice the speed of sound."

“Entry, descent and landing is the most critical and most dangerous part of the mission. Success is never assured. And that’s especially true when we’re trying to land the biggest heaviest and most complicated rover we’ve ever built,” Chen was quoted as saying.

Pauline Hwang

Pauline Hwang, who has worked for JPL for over 15 years, is the Strategic Mission Manager for Mars 2020 Surface Operations, according to her NASA profile. Hwang has previously worked on the Dawn Project, which studied the protoplanets of the asteroid belt, the prior Mars rover missions — Spirit, Opportunity and Curiosity — and, most recently, a Martian lander project called InSight, which reached the planet in 2018.

In an interview with LA Parent, Hwang shared her experience in the space industry. "When I started working at JPL, it did not bother me that there were more males than females," she was quoted as saying. "My biggest challenge/epiphany was realizing that everyone, including me, has this internal unconscious bias of who could make a good manager (you automatically picture similar people who are currently managers) and how certain genders should behave in meetings. For example, it is accepted for a man to be loud, short and direct, but for a woman it can be poorly received and considered too blunt."

Ny Sou Okon

Ny Sou Okon is a Cambodian American flight system engineer who helped build the Perseverance rover alongside others at JPL, including her husband, who is also an engineer. Before she was born, Okon's family fled to Vietnam from their home in Cambodia to escape the Khmer Rouge, according to Press-Telegram. In 1984, when she was only 5 or 6, the family arrived in Texas. Her family eventually settled in Long Beach, where many Cambodians now live. She later went on to graduate with a degree in mechanical engineering at UCLA.

Gregorio Villar III

Filipino American systems engineer Gregorio Villar III, who is head verification and validation engineer for the EDL phase of Perseverance, helped build and test a system that would land a car-sized rover on Mars. Villar also led an international council of atmospheric scientists to characterize the Martian atmosphere, according to PNA. Villar, who was awarded a NASA scholarship in his junior year of college, started his internship at JPL in 2010 and was hired full-time in 2012.

More AAPI scientists and engineers will continue the exploration of Mars through Preserverance. See who they are.
