      To put boots on the Moon—and keep them there—will require bold thinkers ready to tackle the challenges of tomorrow. 

      That’s why NASA’s Office of STEM Engagement at Johnson Space Center in Houston is on a mission to empower the next generation of explorers in science, technology, engineering, and mathematics (STEM). 

      Through the High School Aerospace Scholars (HAS) program, Texas juniors have the opportunity to immerse themselves in space exploration through interactive learning experiences. 

      “HAS is such an important program because we introduce students to the multitude of careers and experiences that contribute to space exploration,” said NASA HAS Activity Manager Jakarda Varnado. “We go beyond asking students who they want to be when they grow up and ask what problems they want to solve.” 

      Meet Former HAS Student Madeline King

      Madeline King always knew she wanted a career in STEM, with a dream of working at NASA influencing her decision to pursue a degree in Engineering.  

      Before joining HAS, King thought scientists mainly worked in labs and engineers focused on design. But the HAS program revealed a different reality—scientists and engineers often collaborated on interdisciplinary projects, sometimes even sharing roles.   
      Official portrait of Madeline King.NASA The program broadened King’s perspective on the diverse paths a STEM degree can lead to. It showed her that careers at NASA offer opportunities across various fields and disciplines. 

      King said participating in HAS helped to strengthen her problem-solving skills and ability to think creatively. The program required students to tackle complex technical tasks independently, emphasizing self-directed learning. King describes HAS as fun, challenging, and engaging, which helped her excel in technical roles.  

      “Learning to digest and internalize this information is a skill I continue to use when getting up to speed in new groups or taking on projects outside my current skill set,” said King.  

      Though King joined HAS during COVID-19, which limited in-person interactions, the experience still made an impact. Her mentors also offered insights into graduate school options, helping her weigh the benefits of advanced degrees against gaining hands-on experience at NASA.  

      The program opened doors to internships at Johnson in the Engineering Robotics and the Avionics Systems Integration Division. Now, she is studying mechanical engineering at the University of Houston, bringing passion and experience in electronics, robotics, education, project management, and aviation. 

      “Early on in my internship journey, HAS shined on my resume,” she said. “It demonstrated that I already had experience with NASA’s culture, values, and mission.” 
      Looking forward, King envisions herself as a flight controller, contributing to both the International Space Station Program and the Artemis campaign. Driven by her passion for NASA’s mission, King is just beginning her journey and is eager to be part of the future of space exploration. 

      “My internships since HAS have allowed me to make small contributions to both of these missions, and I’m excited to specialize as a full-time engineer,” said King.  

      Meet Caroline Vergara

      As a first-generation student, Caroline Vergara lacked the resources to fully explore her interests in aerospace engineering, let alone envision what that career might look like. That all changed when she was accepted into NASA’s HAS program. 

      “The exposure to real-world innovation ignited my desire to be part of something bigger, something that pushes the boundaries of human knowledge and capability,” she said.  
      Caroline Vergara announces the launch of the model rocket she built during her time in the HAS program. NASA/David DeHoyos Touring NASA facilities and watching engineers work on projects opened her eyes to the possibilities in STEM. Today, Vergara is a propulsion design engineering intern at United Launch Alliance, contributing to the Vulcan rocket as a Brooke Owens Fellow. 

      Vergara initially thought working in STEM was mostly about writing equations or running simulations but HAS showed her it is so much more. “A STEM career is about curiosity, collaboration, and the power to change the world,” she said. 

      During the program, Vergara joined a team of students to tackle a mission simulation project. They called themselves “Charlie and the Rocket Factory” and designed a prototype rocket together. Working with peers from all over the country showed her the power of diverse perspectives. She experienced firsthand what it was like to be part of a team with a shared vision, working toward something bigger than themselves. 

      Vergara also discovered her love for 3D printing and computer-aided design through HAS. She spent hours fine-tuning designs, fascinated by the process of turning digital models into physical reality. 

      Her experience with HAS also sparked a desire to give back. She returned to her hometown to share her story and encourage other students to pursue STEM. Partnering with Johnson Community Engagement Lead Jessica Cordero, she organized video conferences with NASA engineers on International Women in Engineering Day to inspire a new wave of students to be part of space exploration. 

      “The aerospace industry is entering a new space age, and we have the unique opportunity to put humans back on the Moon and explore beyond,” she said. 

      Her advice to the Artemis Generation is: “Go for it! You could be part of the generation that changes humanity’s destiny.”

      “My dream is to contribute to space exploration efforts that put humans back on the Moon and beyond, and to one day work in Mission Control Center, where I can help guide those historic missions into the future.” 

      Meet Iker Aguirre

      For Iker Aguirre, the spark that ignited his journey toward a career in aerospace was lit by a passing conversation during his freshman year of high school. A senior classmate described the HAS program as a once-in-a-lifetime experience that cemented his passion for aerospace. That moment stayed with Aguirre, and when the opportunity arose, he did not hesitate to apply. 
      Iker Aguirre inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. “HAS showed me that in order to accomplish something as complex as Artemis, you need a well-rounded set of teams and individuals,” he said. “You don’t need to study aerospace to be in the aerospace industry!” 

      In 2020, Aguirre participated during the remote-only version of HAS, but he recalls that the program still gave him a much deeper understanding of the spaceflight industry. 

      Despite already being interested in aerospace, Aguirre says HAS broadened his horizons, showing him the diverse pathways into the field. Through collaborative projects with peers across Texas, he discovered that solving the challenges of space exploration requires more than just aerospace engineers.  

      The program’s emphasis on teamwork left a lasting impression. During his time with HAS, Aguirre found himself working alongside students from different backgrounds, each bringing unique perspectives to problem-solving. It introduced him to dedicated and passionate people with various personalities and cultures who all shared similar dreams and aspirations as him.  

      Aguirre credits HAS with not only refining his technical skills but also shaping his approach to innovation and teamwork. That experience paid off as he moved through his academic and professional journey, including Pathways program internships with NASA’s Johnson Space Center in Houston and Marshall Space Flight Center in Huntsville, Alabama.  

      “Getting connections at NASA through HAS helped me open many doors so far,” said Aguirre. “I met many good friends through HAS and my internship at Johnson, which I value to this day.” 

      Now pursuing a degree in rocket propulsion, with a focus on turbomachinery design, Aguirre remains committed to advancing space exploration. He hopes to contribute to humanity’s mobility in space, tackling challenges in rocket engine feed systems.

      5 Min Read NASA’s Ames Research Center Celebrates 85 Years of Innovation
      The NACA Ames laboratory in 1944 Credits: NASA 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.” 
      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
      Joseph sweetman ames
      Founding member of the N.A.C.A.
      “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.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.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA/Quincy Eggert NASA’s Armstrong Flight Research Center in Edwards, California, is preparing today for tomorrow’s mission. Supersonic flight, next generation aircraft, advanced air mobility, climate changes, human exploration of space, and the next innovation are just some of the topics our researchers, engineers, and mission support teams focused on in 2024.
      NASA Armstrong began 2024 with the public debut of the X-59 quiet supersonic research aircraft. Through the unique design of the X-59, NASA aims to reduce the sonic boom to make it much quieter, potentially opening the future to commercial supersonic flight over land. Throughout the first part of the year, NASA and international researchers studied air quality across Asia as part of a global effort to better understand the air we breathe. Later in the year, for the first time, a NASA-funded researcher conducted an experiment aboard a commercial suborbital rocket, studying how changes in gravity during spaceflight affect plant biology.
      Here’s a look at more NASA Armstrong accomplishments throughout 2024:
      Our simulation team began work on NASA’s X-66 simulator, which will use an MD-90 cockpit and allow pilots and engineers to run real-life scenarios in a safe environment. NASA Armstrong engineers completed and tested a model of a truss-braced wing design, laying the groundwork for improved commercial aircraft aerodynamics. NASA’s Advanced Air Mobility mission and supporting projects worked with industry partners who are building innovative new aircraft like electric air taxis. We explored how these new designs may help passengers and cargo move between and inside cities efficiently. The team began testing with a custom virtual reality flight simulator to explore the air taxi ride experience. This will help designers create new aircraft with passenger comfort in mind. Researchers also tested a new technology that will help self-flying aircraft avoid hazards. A NASA-developed computer software tool called OVERFLOW helped several air taxi companies predict aircraft noise and aerodynamic performance. This tool allows manufacturers to see how new design elements would perform, saving the aerospace industry time and money. Our engineers designed a camera pod with sensors at NASA Armstrong to help advance computer vision for autonomous aviation and flew this pod at NASA’s Kennedy Space Center in Florida. NASA’s Quesst mission marked a major milestone with the start of tests on the engine that will power the quiet supersonic X-59 experimental aircraft. In February and March, NASA joined international researchers in Asia to investigate pollution sources. The now retired DC-8 and NASA Langley Gulfstream III aircraft collected air measurements over the Philippines, South Korea, Malaysia, Thailand, and Taiwan. Combined with ground and satellite observations, these measurements continue to enrich global discussions about pollution origins and solutions. The Gulfstream IV joined NASA Armstrong’s fleet of airborne science platforms. Our teams modified the aircraft to accommodate a next-generation science instrument that will collect terrain information of the Earth in a more capable, versatile, and maintainable way. The ER-2 and the King Air supported the development of spaceborne instruments by testing them in suborbital settings. On the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment mission (PACE-PAX), the ER-2 validated data collected by the PACE satellite about the ocean, atmosphere, and surfaces. Operating over several countries, researchers onboard NASA’s C-20A collected data and images of Earth’s surface to understand global ecosystems, natural hazards, and land surface changes. Following Hurricane Milton, the C-20A flew over affected areas to collect data that could help inform disaster response in the future. We also tested nighttime precision landing technologies that safely deliver spacecraft to hazardous locations with limited visibility. With the goal to improve firefighter safety, NASA, the U.S. Forest Service, and industry tested a cell tower in the sky. The system successfully provided persistent cell coverage, enabling real-time communication between firefighters and command posts. Using a 1960s concept wingless, powered aircraft design, we built and tested an atmospheric probe to better and more economically explore giant planets. NASA Armstrong hosted its first Ideas to Flight workshop, where subject matter experts shared how to accelerate research ideas and technology development through flight. These are just some of NASA Armstrong’s many innovative research efforts that support NASA’s mission to explore the secrets of the universe for the benefit of all.

      Energy modulators (EM), also known as energy absorbers, are safety-critical components that are used to control shocks and impulses in a load path. EMs are textile devices typically manufactured out of nylon, Kevlar® and other materials, and control loads by breaking rows of stitches that bind a strong base webbing together as shown in Figure 1. A familiar EM application is a fall-protection harness used by workers to prevent injury from shock loads when the harness arrests a fall. EMs are also widely used in parachute systems to control shock loads experienced during the various stages of parachute system deployment.
      Random forest is an innovative algorithm for data classification used in statistics and machine learning. It is an easy to use and highly flexible ensemble learning method. The random forest algorithm is capable of modeling both categorical and continuous data and can handle large datasets, making it applicable in many situations. It also makes it easy to evaluate the relative importance of variables and maintains accuracy even when a dataset has missing values.
      Random forests model the relationship between a response variable and a set of predictor or independent variables by creating a collection of decision trees. Each decision tree is built from a random sample of the data. The individual trees are then combined through methods such as averaging or voting to determine the final prediction (Figure 2). A decision tree is a non-parametric supervised learning algorithm that partitions the data using a series of branching binary decisions. Decision trees inherently identify key features of the data and provide a ranking of the contribution of each feature based on when it becomes relevant. This capability can be used to determine the relative importance of the input variables (Figure 3). Decision trees are useful for exploring relationships but can have poor accuracy unless they are combined into random forests or other tree-based models.
      The performance of a random forest can be evaluated using out-of-bag error and cross-validation techniques. Random forests often use random sampling with replacement from the original dataset to create each decision tree. This is also known as bootstrap sampling and forms a bootstrap forest. The data included in the bootstrap sample are referred to as in-the-bag, while the data not selected are out-of-bag. Since the out-of-bag data were not used to generate the decision tree, they can be used as an internal measure of the accuracy of the model. Cross-validation can be used to assess how well the results of a random forest model will generalize to an independent dataset. In this approach, the data are split into a training dataset used to generate the decision trees and build the model and a validation dataset used to evaluate the model’s performance. Evaluating the model on the independent validation dataset provides an estimate of how accurately the model will perform in practice and helps avoid problems such as overfitting or sampling bias. A good model performs well on
      both the training data and the validation data.
      The complex nature of the EM system made it difficult for the team to identify how various parameters influenced EM behavior. A bootstrap forest analysis was applied to the test dataset and was able to identify five key variables associated with higher probability of damage and/or anomalous behavior. The identified key variables provided a basis for further testing and redesign of the EM system. These results also provided essential insight to the investigation and aided in development of flight rationale for future use cases.
