Sustainability Program Lead
Through awareness campaigns and outreach events, John empowers employees to be mindful of their environmental impact. Whether she is fostering grassroots connections, leading hands-on events, or recognizing colleagues who prioritize climate-aware actions, John remains dedicated to making a lasting, positive impact on the planet.
John credits her Diné heritage and cultural values for fueling her passion to protect and preserve Earth for future generations.
John began her NASA career at White Sands as a document specialist, reviewing schedules and environmental reports. She later transitioned into technical editing and gradually got involved in green initiatives, volunteering her time before eventually stepping into her current leadership role.
Now, she coordinates a sitewide working group dedicated to reducing the facility’s environmental impact and inspires others to think critically about everyday actions and their ripple effects.

“Growing up, I remember a teacher asking how we could make a difference in the world,” she said. “I never forgot that question.”
During the years she spent working in accounting and in the mining industry, she kept returning to that question. It was not until she joined NASA that she found her answer:
“This — this is how I make my difference in the world.”
The work also helped John grow in ways she did not expect.
“I was painfully shy as a kid and terrified of speaking in front of a crowd,” she said. “But when I took on this role, I knew I had to find my voice. I still have timid moments, but the pride I feel in this work helps me push through. I’ve been through a lot, but I’m still here learning, growing, and showing up for the team I now call family.”
John credits her strong support system for that transformation. “I am in awe of the women I’ve worked with,” she said. “I hope I can inspire others as they have inspired me.”

She is committed to leaving the world a better place for the next generation. Her legacy is simple: “Clean air, clean water, and clean land — that’s what I want to pass on.”

Celebrating 25 Years of Continuous Human Presence Aboard the International Space Station
NASA and its partners have supported humans continuously living and working in space since November 2000. A truly global endeavor, the International Space Station has been visited by more than 280 people from 23 countries and a variety of international and commercial spacecraft. The unique microgravity laboratory has hosted more than 4,000 experiments from more than 5,000 researchers in more than 110 countries. The space station also is facilitating the growth of a commercial market in low Earth orbit for research, technology development, and crew and cargo transportation.
NASA created a dedicated logo to symbolize this historic achievement. The logo is visible in the cupola of the space station in this July 17, 2025, image. The central astronaut figure is representative of all those who have lived and worked aboard the station during the 25 years of continuous human presence. In the dark sky of space surrounding the astronaut are 15 stars, which symbolize the 15 partner nations that support the orbiting laboratory.
There is a visual representation of the space station toward the edge of the design, where humans have had a continuous presence for the past 25 years. The Earth represents the planet which the station orbits and that science conducted aboard the orbiting laboratory is for the benefit of all. Integrated into the border of the design is the number “25” to further represent the 25 years of human presence aboard the space station.
After 25 years of continuous human presence, the space station remains a training and proving ground for deep space missions, enabling NASA to focus on Artemis missions to the Moon and Mars.

NASA Rehearses How to Measure X-59’s Noise Levels
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA test pilot Nils Larson walks around an F-15B research aircraft for a rehearsal flight supporting the agency’s Quesst mission at NASA’s Armstrong Flight Research Center in Edwards, California. The flight was part of a full-scale dress rehearsal for Phase 2 of the mission, which will eventually measure quiet sonic thumps generated by the X-59. The flight series helped NASA teams refine procedures and practice data collection ahead of future X-59 flights.NASA/Christopher LC ClarkIn a stretch of California’s Mojave Desert, NASA conducted a full-scale “dress rehearsal” to prepare how it will measure the noise generated by the X-59 quiet supersonic research aircraft.
The team behind the successful test flight series operates under NASA’s Commercial Supersonic Technology project. Beginning June 3 and concluding this week, researchers conducted a dry run for Phase 2 of NASA’s Quesst mission, when it will capture audio of the sonic thumps the X-59 will produce, rather than loud sonic booms associated with supersonic flight.
“The dress rehearsal was critical for us,” said Larry Cliatt, sub-project manager for the Quesst acoustic validation phase, who is based at NASA’s Armstrong Flight Research Center in Edwards, California. “It gave us the opportunity to run through every aspect of our operation, from flight planning to data collection. In between those activities, we practiced aircraft operations, setting up the Ground Recording Systems, meteorological data collecting, and refining control room procedures. We were able to fine-tune our timelines, improve communication across teams, and ensure that when we perform these test with the X-59 aircraft, everything will run smoothly.”
A NASA TG-14 glider aircraft is prepared for flight at NASA’s Armstrong Flight Research Center in Edwards, California, in support of the agency’s Quesst mission. The aircraft is equipped with onboard microphones to capture sonic boom noise generated during rehearsal flights, helping researchers measure the acoustic signature of supersonic aircraft closer to the ground.NASA/Jim RossDuring the tests, at NASA Armstrong, an F-15B aircraft served as a stand-in for the X-59, flying faster than the speed of sound and making multiple passes over the Mojave sands. While it flew, researchers captured acoustic data using a linear array of ground recording systems spaced across miles of open desert, recorded weather readings, and measured the shock waves it generated.
For a supersonic aircraft like the F-15B, shock waves typically result in loud sonic booms, but the X-59 is designed to diffuse them in a way that will dramatically limit noise.
NASA’s Quesst mission aims to enable quiet supersonic flight over land using data from the X-59. The experimental aircraft will begin making its first flights this year – the first phase of Quesst.
A NASA intern sets up ground recording system (GRS) units in California’s Mojave Desert during a Phase 2 rehearsal of the agency’s Quesst mission. The GRS units were placed across miles of desert terrain to capture the acoustic signature of supersonic aircraft during rehearsal flights and in preparation for the start of the actual tests.NASA/Christopher LC ClarkBut even before it takes to the air, the mission began its preparations for Phase 2 with the dry run, which focused on practicing under realistic test conditions and identifying issues before the official campaign begins, not collecting data from the F-15B.
Through Quesst’s development of the X-59, NASA will deliver design tools and technology for quiet supersonic airliners that will achieve the high speeds desired by commercial operators without disturbing people on the ground. NASA will also validate design tools through ground and flight testing, providing aircraft manufacturers the ability to explore new quiet supersonic concepts and have confidence that their resulting designs will meet requirements for quiet flight.
Most importantly, Quesst will gather data to understand community response to sounds generated during flight – key knowledge for a quiet supersonic future.

Hubble Spies Swirling Spiral The NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 3285B, a member of the Hydra I cluster of galaxies. ESA/Hubble & NASA, R. J. Foley (UC Santa Cruz)The swirling spiral galaxy in this NASA/ESA Hubble Space Telescope image is NGC 3285B, which resides 137 million light-years away in the constellation Hydra (the Water Snake). Hydra has the largest area of the 88 constellations that cover the entire sky in a celestial patchwork. It’s also the longest constellation, stretching 100 degrees across the sky. It would take nearly 200 full Moons, placed side by side, to reach from one side of the constellation to the other.
NGC 3285B is a member of the Hydra I cluster, one of the largest galaxy clusters in the nearby universe. Galaxy clusters are collections of hundreds to thousands of galaxies bound to one another by gravity. The Hydra I cluster is anchored by two giant elliptical galaxies at its center. Each of these galaxies is about 150,000 light-years across, making them about 50% larger than our home galaxy, the Milky Way.
NGC 3285B sits on the outskirts of its home cluster, far from the massive galaxies at the center. This galaxy drew Hubble’s attention because it hosted a Type Ia supernova in 2023. Type Ia supernovae happen when a type of condensed stellar core called a white dwarf detonates, igniting a sudden burst of nuclear fusion that briefly shines about 5 billion times brighter than the Sun. The supernova, named SN 2023xqm, is visible here as a blueish dot on the left edge of the galaxy’s disk.
Hubble observed NGC 3285B as part of an observing program that targeted 100 Type Ia supernovae. By viewing each of these supernovae in ultraviolet, optical, and near-infrared light, researchers aim to disentangle the effects of distance and dust, both of which can make a supernova appear redder than it actually is. This program will help refine cosmic distance measurements that rely on observations of Type Ia supernovae.
