Preparations for Next Moonwalk Simulations Underway (and Underwater)
Latha Balijepalle, a senior database administrator at NASA Ames, encourages others to take a risk and pursue challenges in their work, like trying something new that might open doors to a new opportunity.NASA/Brandon Torres Navarrete When Madhavi Latha Balijepalle noticed that her morning commute took her past NASA Ames Research Center in California’s Silicon Valley, she set a new career goal for herself: working for NASA.
“I started manifesting it, thinking about it every day as I drove by. When I started looking for a new job, I saw an opening and decided to apply,” said Balijepalle, a senior database administrator working at the Airspace Operations Laboratory (AOL) at NASA Ames.
Eight and a half years later, she supports the researchers and developers who research next-generation solutions to advance aircraft technology and air traffic management.
A journey into the unknown
Balijepalle’s journey to NASA started thousands of miles away. She grew up in a small town in southern India, studying electrical engineering in college and establishing a career in information technology, working in C++ and Python.
When her husband found a job opportunity in the United States, Balijepalle’s life took an unexpected turn.
“I never planned to move to America,” said Balijepalle. “It was not easy to come here, even though my husband had a job. I stayed in India for almost nine months, before he found a different job that would help us with my visa and documentation.”
After settling into her new country, growing her family, and developing in her new career, Balijepalle began to ponder her dream job at NASA. She and her younger daughter, a fellow space fan, enjoyed talking about the agency’s work in space, and when a Linux administrator position opened up, she jumped at the chance.
A dream job becomes reality
At the lab, Balijepalle was initially responsible for managing the lab’s Linux servers and applications. Today, she also supports researchers and developers with development, automation, and deployment of their work.
“Latha is the lifeblood of the lab,” said Jeff Homola, co-leader of the Airborne Operations Laboratory at NASA Ames. “Without her unwavering dedication to making sure our systems are safe, secure, up to date, and running smoothly, we would not be able to do what we do in the lab.”
One of Balijepalle’s proudest achievements during her NASA career is her language skills. Growing up, she spoke Telugu and Hindi, and learned English, but communication was still a challenge when she arrived at NASA.
“I spoke English when I came to America, but not as well, and not using the technical language we use at NASA,” said Balijepalle. “I’m proud that I’ve improved my communications skills.”
“Step outside your comfort zone”
Looking back on the commute that changed her life, Balijepalle says she owes it all to being up to the challenge.
“I wasn’t a risk taker, I didn’t think about stepping outside my comfort zone, but as I drove by NASA Ames each day, I started to think about astronauts. They step outside their comfort zone and leave the planet, so maybe I could take a risk, too.”
For those who also dream of working at NASA one day, Balijepalle has some advice: try doing it her way.
“Start thinking about it and manifesting your dream. Maybe it will come true, and maybe it won’t, but you might as well try.”

2024 Year in Review – Highlights from NASA in Silicon Valley
by Tiffany Blake
As NASA’s Ames Research Center in California’s Silicon Valley enters its 85th year since its founding, join us as we take a look back at some of our highlights of science, engineering, research, and innovation from 2024.
Ames Arc Jets Play Key Role in Artemis I Orion Spacecraft Heat Shield Findings
A block of Avcoat undergoes testing inside an arc jet test chamber at NASA Ames. The test article, configured with both permeable (upper) and non-permeable (lower) Avcoat sections for comparison, helped to confirm understanding of the root cause of the loss of charred Avcoat material that engineers saw on the Orion spacecraft after the Artemis I test flight beyond the Moon. photo credit: NASA Researchers at Ames were part of the team tasked to better understand and identify the root cause of the unexpected char loss across the Artemis I Orion spacecraft’s heat shield. Using Avcoat material response data from Artemis I, the investigation team was able to replicate the Artemis I entry trajectory environment — a key part of understanding the cause of the issue — inside the arc jet facilities at NASA Ames.

Working with multiple partners, our scientists and engineers helped inform ecosystem management by joining satellite measurements of Earth with animal tracking data. In collaboration with the U.S. Geological Survey, a NASA team continued testing a specialized instrument package to stay in-the-know about changes in river flow rates.
Revealing the Mysteries of Asteroids in Our Solar System

NASA’s Ames Research Center Celebrates 85 Years of Innovation
by Rachel Hoover
Ames Research Center in California’s Silicon Valley pre-dates a lot of things. The center existed before NASA – the very space and aeronautics agency it’s a critical part of today. And of all the marvelous advancements in science and technology that have fundamentally changed our lives over the last 85 years since its founding, one aspect has remained steadfast; an enduring commitment to what’s known by some on-center simply as, “an atmosphere of freedom.”
The NACA Ames laboratory in 1944.Image credit: NASA Years before breaking ground at the site that would one day become home to the world’s preeminent wind tunnels, supercomputers, simulators, and brightest minds solving some of the world’s toughest challenges, Joseph Sweetman Ames, the center’s namesake, described a sentiment that would guide decades of innovation and research:
“My hope is that you have learned or are learning a love of freedom of thought and are convinced that life is worthwhile only in such an atmosphere,” he said in an address to the graduates of Johns Hopkins University in June 1935.
That spirit and the people it attracted and retained are a crucial part of how Ames, along with other N.A.C.A. research centers, ultimately made technological breakthroughs that enabled humanity’s first steps on the Moon, the safe return of spacecraft through Earth’s atmosphere, and many other discoveries that benefit our day-to-day lives.
Russell Robinson momentarily looks to the camera while supervising the first excavation at what would become Ames Research Center.Image credit: NACA “In the context of my work, an atmosphere of freedom means the freedom to pursue high-risk, high-reward, innovative ideas that may take time to fully develop and — most importantly — the opportunity to put them into practice for the benefit of all,” said Edward Balaban, a researcher at Ames specializing in artificial intelligence, robotics, and advanced mission concepts.
Balaban’s career at Ames has involved a variety of projects at different stages of development – from early concept to flight-ready – including experimenting with different ways to create super-sized space telescopes in space and using artificial intelligence to help guide the path a rover might take to maximize off-world science results. Like many Ames researchers over the years, Balaban shared that his experience has involved deep collaborations across science and engineering disciplines with colleagues all over the center, as well as commercial and academic partners in Silicon Valley where Ames is nestled and beyond. This is a tradition that runs deep at Ames and has helped lead to entirely new fields of study and seeded many companies and spinoffs.
Before NASA, Before Silicon Valley: The 1939 Founding of Ames Aeronautical Laboratory “In the fields of aeronautics and space exploration the cost of entry can be quite high. For commercial enterprises and universities pursuing longer term ideas and putting them into practice often means partnering up with an organization such as NASA that has the scale and multi-disciplinary expertise to mature these ideas for real-world applications,” added Balaban.
“Certainly, the topics of inquiry, the academic freedom, and the benefit to the public good are what has kept me at Ames,” reflected Ross Beyer, a planetary scientist with the SETI Institute at Ames. “There’s not a lot of commercial incentive to study other planets, for example, but maybe there will be soon. In the meantime, only with government funding and agencies like NASA can we develop missions to explore the unknown in order to make important fundamental science discoveries and broadly share them.”
For Beyer, his boundary-breaking moment came when he searched – and found – software engineers at Ames capable and passionate about open-source software to generate accurate, high-resolution, texture-mapped, 3D terrain models from stereo image pairs. He and other teams of NASA scientists have since applied that software to study and better understand everything from changes in snow and ice characteristics on Earth, as well as features like craters, mountains, and caves on Mars or the Moon. This capability is part of the Artemis campaign, through which NASA will establish a long-term presence at the Moon for scientific exploration with commercial and international partners. The mission is to learn how to live and work away from home, promote the peaceful use of space, and prepare for future human exploration of Mars.
“As NASA and private companies send missions to the Moon, they need to plan landing sites and understand the local environment, and our software is freely available for anyone to use,” Beyer said. “Years ago, our management could easily have said ‘No, let’s keep this software to ourselves; it gives us a competitive advantage.’ They didn’t, and I believe that NASA writ large allows you to work on things and share those things and not hold them back.”
When looking forward to what the next 85 years might bring, researchers shared a belief that advancements in technology and opportunities to innovate are as expansive as space itself, but like all living things, they need a healthy atmosphere to thrive. Balaban offered, “This freedom to innovate is precious and cannot be taken for granted. It can easily fall victim if left unprotected. It is absolutely critical to retain it going forward, to ensure our nation’s continuing vitality and the strength of the other freedoms we enjoy.”
Ames Aeronautical Laboratory.Image credit: NACA Today Marks the Retirement of the Astrogram Newsletter
by Astrid Albaugh
For 66 years, the Astrogram has told the story of NASA’s Ames Research Center. Over those six-plus decades, the newsletter has documented hundreds of missions led by Ames, the progression of Hangar One’s reclamation, space shuttle launches with Ames’ payloads aboard them, countless VIP visits, and everything in between.
Ames published the first edition of the Astrogram in October 1958, coinciding with the transition of the center from its original incarnation as the National Advisory Committee for Aeronautics Ames Aeronautical Laboratory to a National Aeronautics and Space Administration (NASA) research center.
The newsletter has evolved over time, alongside the center. From October 1958 through January 2016, the Astrogram was published in print, before a digital edition was developed. In January 2016, the Astrogram transitioned to a digital-only format. Below are examples of some of the Astrogram issues from over the years. More are forthcoming from 1998 and prior once they are retrieved from the archives.
October 2014 Astrogram September 2010 Astrogram I have served as the editor of the Astrogram since February 1998. Over the past quarter century, it has been an interesting, and sometimes quite challenging, task for me to capture the breadth and depth of Ames’s story and ensure that we always published the newsletter on time. I still remember trekking over to the center’s imaging office to review the physical negatives and images that the Ames photographers had taken of events onsite and select the most compelling photos. I used a very early version of visual design software to craft the layout. When the paper was completed, I’d file it onto a CD and then hand it to the courier who would drive from the San Francisco printshop to pick it up from me. Once and awhile, someone would request to have an additional feature added, requiring multiple trips up the 101 and back. Sometimes I’d come in on the weekends to work on the paper, due to late submissions, much to the chagrin of my kids.
July 2007 Astrogram It has been a pleasure serving as the editor over the past quarter century, almost as many years as my kids are old. A person once asked me if I had changed my name to Astrid since it’s so like the word Astrogram. Any relationship between the newsletter and my name is simply serendipity. I have enjoyed being behind the scenes, mostly working diligently at my computer. Many at Ames know my name because of the newsletter but may have never met me in person. It’s been amusing sometimes when I encounter someone who can’t put a finger as to why they knew my name but didn’t recognize me standing in front of them. Their usual response when they realized why they know me was, “Ah, Astrid of the Astrogram.”
March 20, 1998 Astrogram Just as NASA innovates, the content of the Astrogram has to innovate as well. Many of the stories that you used to read in the Astrogram, you can now find on our NASA Ames web page here. If you would like to access past, archived issues of the Astrogram, going back to 1958, please consult the Ames Research Center Archives. I will continue to help tell Ames’s story, just using new platforms.
Whether this is your first issue or you have been an Astrogram supporter for decades, thank you for reading!

La sonda medirá las ondas de choque del X-59 de la NASA.NASA/Steve Freeman Read this story in English here.
La NASA pronto pondrá a prueba los avances realizados en una herramienta clave para medir los singulares ‘golpes sónicos’ que su avión supersónico silencioso de investigación X-59 producirá durante el vuelo.
Una sonda de detección de impactoses una sonda de datos de aire en forma cónica desarrollada con características específicas para capturar las singulares ondas de choque que producirá el X-59. Investigadores del Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California, desarrollaron dos versiones de la sonda para recopilar datos precisos de presión durante el vuelo supersónico. Una de las sondas está optimizada para mediciones de campo cercano, capturando las ondas de choque que se producen muy cerca de donde las generará el X-59. La segunda sonda de detección de impactos medirá el centro del campo y recopilará datos a altitudes de entre 5.000 y 20.000 pies por debajo del avión.
Cuando un avión vuela a velocidades supersónicas, genera ondas de choque que viajan a través del aire circundante, produciendo fuertes estampidos sónicos. El X-59 está diseñado para desviar esas ondas de choque, reduciendo los fuertes estampidos sónicos a golpes sónicos más silenciosos. Durante los vuelos de prueba, un avión F-15B con una sonda de detección de impactos acoplada a su morro volará con el X-59. La sonda, de aproximadamente 1,80 metros (6 pies), recolectará continuamente miles de muestras de presión por segundo, captando los cambios de presión del aire mientras vuela a través de ondas de choque. Los datos de los sensores serán vitales para validar los modelos informáticos que predicen la fuerza de las ondas de choque producidas por el X-59, la pieza central de la misión Quesst de la NASA.
“Una sonda de detección de impactos actúa como fuente de la verdad, comparando los datos previstos con las mediciones del mundo real”, dijo Mike Frederick, investigador principal de la NASA para la sonda.
Para la sonda de campo cercano, el F-15B volará cerca del X-59 a su altitud de crucero de aproximadamente 18.000 metros (55.000 pies), utilizando una configuración de “seguir al líder” que permitirá a los investigadores analizar ondas de choque en tiempo real. La sonda de campo medio, destinada para misiones separadas, recopilará datos más útiles a medida que las ondas de choque viajen más cerca al suelo.
La capacidad de las sondas para captar pequeños cambios de presión es especialmente importante para el X-59, ya que se espera que sus ondas de choque sean mucho más débiles que las de la mayoría de los aviones supersónicos. Al comparar los datos de las sondas con las predicciones de modelos de computadora avanzados, los investigadores pueden evaluar con mayor precisión.
“Las sondas tienen cinco puertos de presión, uno en la punta y cuatro alrededor del cono”, explica Frederick. “Estos puertos miden los cambios de presión estática a medida que el avión vuela a través de las ondas de choque, lo que nos ayuda a comprender las características de choque de un avión en particular”. Estos puertos combinan sus mediciones para calcular la presión local, la velocidad y la dirección del flujo de aire.
Los investigadores pronto evaluarán actualizaciones de la sonda de detección de impactos de campo cercano a través de vuelos de prueba, en los que la sonda, montada en un F-15B, recopilará datos persiguiendo a un segundo F-15 durante un vuelo supersónico. Las actualizaciones de la sonda incluyen la colocación de los transductores de presión – dispositivos que miden la presión del aire en el cono – a sólo 5 pulgadas de sus puertos. Los diseños anteriores colocaban esos transductores a casi 3 metros (12 pies) de distancia, lo que retrasaba el tiempo de grabación y distorsionaba las mediciones.
La sensibilidad a la temperatura de los diseños anteriores también presentó un desafío, ya que provocó fluctuaciones en la precisión cuando cambiaban las condiciones. Para solucionar esto, el equipo diseñó un sistema de calefacción para mantener los transductores de presión a una temperatura constante durante el vuelo.
“La sonda cumplirá los requisitos de resolución y precisión de la misión Quesst”, afirmó Frederick. “Este proyecto muestra cómo la NASA puede tomar tecnología existente y adaptarla para resolver nuevos desafíos”.
