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.

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
With a shared commitment to fostering U.S. economic growth that benefits the American public, NASA’s Space Technology Mission Directorate and the Department of Commerce’s U.S. Patent and Trademark Office (USPTO) have signed a memorandum of understanding to strengthen collaboration in transferring federally-developed technology into the private sector, known as tech transfer.
“NASA has to invent new technology every day to carry out audacious missions like building an outpost on the Moon or looking for signs of life on the frozen moons of distant planets,” said Clayton Turner, associate administrator of the agency’s Space Technology Mission Directorate. “That is one of our greatest strengths. And with the help of the U.S. Patent and Trademark Office, we’re streamlining the process of getting those inventions into the hands of the public, boosting the economy, and benefiting everyone on Earth along the way.”
The agency’s Space Technology Mission Directorate and USPTO have been working together to share information and cooperate in mutual areas of interest, find ways to advance both agencies’ technology transfer missions, identify barriers to technology transfer, and coordinate initiatives to overcome those barriers. By combining expertise, both agencies are driving inclusive innovation and adoption of best practices, which will advance commercialization of the space agency’s most cutting-edge technology.
As part of the new agreement, NASA and USPTO are conducting an extensive study of technology transfer best practices across university and federal labs. The effort will increase opportunities for learning and growth in the technology transfer community.
“NASA’s Technology Transfer program and the U.S. Patent and Trademark Office had candid conversations with dozens of tech transfer experts about what we could do better,” said Dan Lockney, executive for NASA’s Technology Transfer program. “I can’t wait to share what we’ve learned with the entire tech transfer community nationwide. We look forward to addressing common challenges, and this paper will offer some assurance that we are on a solid, strong path to transferring technologies effectively.”
The two agencies will publish a detailed study of their findings, which will be shared at the Federal Laboratory Consortium for Technology Transfer’s national meeting in the spring. The effort will increase opportunities for learning and growth in the technology transfer community.
“We are excited to join NASA’s Space Technology Mission Directorate in publishing and sharing this insight with the larger tech transfer community, so that everyone can benefit from the successes and lessons learned from our study participants,” said Parikha Solanki, senior advisor at the U.S. Patent and Trademark Office. “We hope that the impact of this study will extend well beyond the paper, such that it might be a springboard for ongoing dialogue and knowledge sharing between tech transfer practitioners across institutions, ultimately for the benefit of the public at large.”

This article is from the 2024 Technical Update.
The NESC evaluated material compatibility of some common aerospace metals in monomethylhydrazine (MMH) and nitrogen tetroxide (MON-3). Previous work had identified a lack of quantitative compatibility data for nickel alloy 718, 300 series stainless steel, and titanium Ti-6Al-4V in MMH and MON-3 to support the use of zero-failure-tolerant, thin-walled pressure barriers in these propellants. Static (i.e., not flowing) general corrosion and electrochemistry testing was conducted, evaluating varied processing forms and heat treatment of the metals, water content of propellant, and exposure duration. Corrosion-rate data for all tested product forms, fluids, and durations were on the order of 1 x 10–6 inch per year rather than the previously documented “less than 1 x 10–3 inch per year”. The majority of the corrosion products were seen in the first 20 days of exposure, with an overall corrosion rate decreasing with time due to the increased divisor (time). It is therefore recommended that corrosion testing be performed at multiple short-term durations to inform the need for longer-duration testing.
Background
Nickel alloy 718, 300 series stainless steel, and Ti-6Al-4V are commonly used in storable propulsion systems (i.e., MMH/MON-3), but a concern was raised regarding what quantitative compatibility data were available for proposed zero-failure-tolerant, thin-walled (~0.005 to 0.010 inch thickness) pressure barrier designs. A literature search found that limited and conflicting data were available for commonly used aerospace metals in MMH and MON-3. For example, corrosion behavior was listed qualitatively (e.g., “A” rating), data on materials and fluids tested were imprecise, fluids were identified as contaminated without describing how they were contaminated, no compatibility data were found on relevant geometry specimens (i.e., very thin-walled or convoluted), and limited data were available to quantify differences between tested materials and flight components. When corrosion data were quantified, documented sensitivity was “1 x 10–3 inch per year or less”, which is insufficient for assessing long-duration, thin-walled, flight-weight applications.
Discussion
General corrosion testing was performed with a static/non-flowing configuration based on NASA-STD-6001, Test 15 [1]. Design of experiments methods were used to develop a test matrix varying material, propellant, propellant water content, and tested duration. Materials tested were nickel alloy 718 (solution annealed sheet, aged sheet, aged/welded sheet, and hydroformed bellows), 300 series stainless steel (low carbon sheet, titanium stabilized sheet, and hydroformed bellows), and Ti 6Al-4V sheet. Samples were tested in sealed test tubes in MMH and MON-3 with water content ranging from as-received (“dry”) up to specification allowable limits [2,3]. Tested durations ranged from 20 to 365 days. Measurements included inductively coupled plasma mass spectrometry (ICPMS) to identify corrosion products and their concentrations in test fluid, gravimetric (i.e., scale) measurements pre- and post-exposure, and visual inspection. Bimetallic pairs (titanium stabilized 300 series stainless steel: Ti 6Al-4V and nickel alloy 718: Ti 6Al-4V) were tested for up to 65 days in both MMH and MON-3. The test setup incorporated important features of the test standard (e.g., electrode spacing and finish) and adapted the configuration for MMH/MON-3 operation. Measurements included potential difference and current flow between samples. Figure 1 shows images of the general corrosion and bimetallic pair test setups.
Test Results
For all tested materials and product forms, corrosion rates were on the order of 1 x 10–6 inch per year in MMH or MON-3, three orders of magnitude lower than historically reported. Corrosion products were generated in the first 20 days of exposure, and corrosion rate decreased with time due to the increase in divisor (i.e., time). Corrosion products increased as the water content of the propellants increased but remained in the same order of magnitude between the as-received dry propellant and propellant containing the maximum water content allowed by specification. Figure 2 illustrates test results for corrosion rate, mass loss with duration, and mass loss with water content. It is important to note that water has been demonstrated to contribute to flow decay even when water is within the specification allowable limit, and previous NASA-STD-6001 Test 15 data have demonstrated susceptibility of some nickel alloys to crevice-type corrosion attack [4]. Therefore, these results do not reduce the importance of considering the system impact of water content and evaluating for crevice corrosion behavior. Finally, in the bimetallic pair testing, tested materials did not measurably corrode in MON-3 and MMH within specification-allowable water content, as evidenced by no visual indications of corrosion and very low electrical interaction (i.e., corrosion rates derived to be less than 1 microinch per year from electrical interaction).
Recommendations
It is recommended that corrosion testing be performed at multiple shortterm durations to inform the need for longer-duration testing.

NASA AI, Open Science Advance Natural Disaster Research and Recovery
Hurricane Ida is pictured as a category 2 storm from the International Space Station as it orbited 264 miles above the Gulf of Mexico. In the foreground is the Canadarm2 robotic arm with Dextre, the fine-tuned robotic hand, attached. NASA By Lauren Perkins
When you think of NASA, disasters such as hurricanes may not be the first thing to come to mind, but several NASA programs are building tools and advancing science to help communities make more informed decisions for disaster planning.
Empowered by NASA’s commitment to open science, the NASA Disasters Program supports disaster risk reduction, response, and recovery. A core element of the Disasters Program is providing trusted, timely, and actionable data to aid organizations actively responding to disasters.
Hurricane Ida made landfall in Louisiana Aug. 21, 2021, as a category 4 hurricane, one of the deadliest and most destructive hurricanes in the continental United States on record. The effects of the storm were widespread, causing devastating damage and affecting the lives of millions of people.
During Hurricane Ida, while first responders and other organizations addressed the storm’s impacts from the ground, the NASA Disasters program was able to provide a multitude of remotely sensed products. Some of the products and models included information on changes in soil moisture, changes in vegetation, precipitation accumulations, flood detection, and nighttime lights to help identify areas of power outages.
Image Before/After The NASA team shared the data with its partners on the NASA Disasters Mapping Portal and began participating in cross-agency coordination calls to determine how to further aid response efforts. To further connect and collaborate using open science efforts, NASA Disasters overlaid publicly uploaded photos on their Damage Proxy Maps to provide situational awareness of on-the-ground conditions before, during, and after the storm.
Immediate post-storm response is critical to saving lives; just as making informed, long- term response decisions are critical to providing equitable recovery solutions for all. One example of how this data can be used is blue tarp detection in the aftermath of Hurricane Ida.
Using artificial intelligence (AI) with NASA satellite images, the Interagency Implementation and Advanced Concepts Team (IMPACT), based at NASA’s Marshall Space Flight Center in Huntsville, Alabama, conducted a study to detect the number of blue tarps on rooftops in the aftermath of hurricanes, such as Ida, as a way of characterizing the severity of damage in local communities.
An aerial photograph shows damaged roofs from Hurricane Maria in 2017 in Barrio Obrero, Puerto Rico. In the wake of the hurricane, the Federal Emergency Management Agency (FEMA) and United States Army Corps of Engineers distributed 126,000 blue tarps and nearly 60,000 temporary blue roofs to people awaiting repairs on damaged homes. NASA While disasters cannot be avoided altogether, timely and accessible information helps communities worldwide reduce risk, improve response, hasten recovery, and build disaster resilience.
Through an initiative led by NASA’s Office of the Chief Science Data Officer, NASA and IBM are developing five open-source artificial intelligence foundation models trained on NASA’s expansive satellite repositories. This effort will help make NASA’s vast, ever-growing amounts of data more accessible and usable. Leveraging NASA’s AI expertise allows users to make faster, more informed decisions. User applications of the Prithvi Earth Foundation Models could range from identifying flood risks and predicting crop yields to forecasting long range atmospheric weather patterns.
“NASA is dedicated to ensuring that our scientific data are accessible and beneficial to all. Our AI foundation models are scientifically validated and adaptable to new data, designed to maximize efficiency and lower technical barriers. This ensures that even in the face of challenging disasters, response teams can be swift and effective,” said Kevin Murphy, NASA’s chief science data officer. “Through these efforts, we’re not only advancing scientific frontiers, but also delivering tangible societal benefits, providing data that can safeguard lives and improve resilience against future threats.”
Hear directly from some of the data scientists building these AI models, the NASA disaster response team, as well as hurricane hunters that fly directly into these devastating storms on NASA’s Curious Universe podcast.
