Joseph Ladner’s experiences working at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, motivate him to “pay it forward” so more people can be a part of something great.

“It is exciting to be at a place like NASA Stennis that continues to reinvent itself to stay relevant,” Ladner said. “You can do just about anything you can imagine with a workforce committed to its success.”

The Gulfport, Mississippi, resident is the lead budget analyst in the NASA Stennis Office of the Chief Financial Officer. His team manages budgets that fund the nation’s premier propulsion test site.

Ladner can point to three pivotal moments propelling him to a career with NASA. The first came by attending ASTRO CAMP at NASA Stennis every summer as a child. The thrilling experiences of launching paper rockets and conducting science experiments left him with the question, “How do I get to work there?”

The answer came into focus years later. Much like launching paper rockets, Ladner’s career started at ground level before reaching higher heights.

He started on the lowest end of the General Schedule pay scale as a GS-1 clerk for the Naval Oceanographic Office, located at NASA Stennis, while attending Mississippi Gulf Coast Community College.

A second pivotal moment also came during this time. The Saucier, Mississippi, native credits mentor Pamela Stenum for putting him on a career path in procurement so he could use the math and analytical skills that came natural to him.

The clerk role, expected to be only for one semester, continued through Ladner’s studies at The University of Southern Mississippi, where he earned a bachelor’s degree in Business Administration.

“I literally came in from the bottom, and someone saw potential in me,” Ladner said. “She realized I was a hard worker and that I cared about the product I was putting out.”

The third, and most profound, moment leading Ladner to a NASA career happened when the space shuttle Columbia orbiter suffered a catastrophic failure during return to Earth.

“I will never forget standing in the crowd that morning waiting for the launch of Columbia (in 2003) and hearing the commander over the loudspeakers thank everyone for the efforts to get them to this point and saying farewell to his family,” Ladner said. “No one knew it would ultimately be the crew’s last farewell. That tragic incident left me with a greater sense that there are many opportunities, but life is short. That thought and NASA’s return to flight mission left me with a desire to be part of NASA.”

Ladner started his career with the agency two years later and has worked inspired ever since. His role as lead budget analyst contributes to the Artemis campaign that will establish the foundation for long-term scientific exploration of the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

His job currently involves navigating challenges of increased costs and reduced budgets. From Ladner’s perspective, the challenges present opportunities for innovation and new ideas. 

“Knowing my work is part of a greater cause impacting the Artemis Generation that could make a difference to society is the best thing about working at NASA Stennis,” Ladner said. “There is some awe and wonder about working at NASA, so it is neat to say you are a part of that.”

      Eclipses, Auroras, and the Spark of Becoming: NASA Inspires Future Scientists
      In the heart of Alaska’s winter, where the night sky stretches endlessly and the aurora dances across the sky in a display of ethereal beauty, nine undergraduate students from across the United States were about to embark on a transformative journey. These students had been active ‘NASA Partner Eclipse Ambassadors’ in their home communities, nine of more than 700 volunteers who shared the science and awe of the 2024 eclipse with hundreds of thousands of people across the country as part of the NASA Science Activation program’s Eclipse Ambassadors project. Now, these nine were chosen to participate in a once-in a lifetime experience as a part of the “Eclipses to Aurora” Winter Field School at the University of Alaska Fairbanks. Organized by the Astronomical Society of the Pacific and NASA’s Aurorasaurus Citizen Science project, supported by NASA, this program offered more than just lectures—it was an immersive experience into the wonders of heliophysics and the profound connections between the Sun and Earth.
      From January 4 to 11, 2025, the students explored the science behind the aurora through seminars on solar and space physics, hands-on experiments, and tours of cutting-edge research facilities like the Poker Flat Research Range. They also gained invaluable insight from Athabaskan elders, who shared local stories and star knowledge passed down through generations. As Feras recalled, “We attended multiple panels on solar and space physics, spoke to local elders on their connection to the auroras, and visited the Poker Flat Research Range to observe the stunning northern lights.”
      For many students, witnessing the aurora was not only a scientific milestone, but a deeply personal and emotional experience. One participant, Andrea, described it vividly: “I looked to the darkest horizon I could find to see my only constant dream fulfilled before my eyes, so slowly dancing and bending to cradle the stars. All I could do, with my hands frozen and tears falling, I began to dream again with my eyes wide open.” Another student, Kalid, reflected on the shared human moment: “Standing there under the vast Alaskan sky… we were all just people, looking up, waiting for something magical. The auroras didn’t care about our majors or our knowledge—they brought us together under the same sky.”
      These moments of wonder were mirrored by a deeper sense of purpose and transformation. “Over the course of the week, I had the incredible opportunity to explore auroras through lectures on solar physics, planetary auroras, and Indigenous star knowledge… and to reflect on these experiences through essays and presentations,” said Sophia. The Winter Field School was more than an academic endeavor—it was a celebration of science, culture, and shared human experience. It fostered not only understanding but unity and awe, reminding everyone involved of the profound interconnectedness of our universe.
      The impact of the program continues to resonate. For many students, that one aurora-lit week in Alaska became a turning point in the focus of their careers. Sophia has since been accepted into graduate school to pursue heliophysics. Vishvi, inspired by the intersection of science and society, will begin a program in medical physics at the University of Pennsylvania this fall. And Christy, moved by her time at the epicenter of aurora research, has applied to the Ph.D. program in Space Physics at the University of Alaska Fairbanks—the very institution that helped spark her journey. Their stories are powerful proof that the Winter Field School didn’t just teach—it awakened purpose, lit new paths, and left footprints on futures still unfolding.

      NASA Observes First Visible-light Auroras at Mars
      On March 15, 2024, near the peak of the current solar cycle, the Sun produced a solar flare and an accompanying coronal mass ejection (CME), a massive explosion of gas and magnetic energy that carries with it large amounts of solar energetic particles. This solar activity led to stunning auroras across the solar system, including at Mars, where NASA’s Perseverance Mars rover made history by detecting them for the first time from the surface of another planet.
      The first visible-light image of green aurora on Mars (left), taken by the Mastcam-Z instrument on NASA’s Perseverance Mars rover. On the right is a comparison image of the night sky of Mars without aurora but featuring the Martian moon Deimos. The moonlit Martian night sky, lit up mostly by Mars’ nearer and larger moon Phobos (outside the frame) has a reddish-brown hue due to the dust in the atmosphere, so when green auroral light is added, the sky takes on a green-yellow tone, as seen in the left image. NASA/JPL-Caltech/ASU/MSSS/SSI “This exciting discovery opens up new possibilities for auroral research and confirms that auroras could be visible to future astronauts on Mars’ surface.” said Elise Knutsen, a postdoctoral researcher at the University of Oslo in Norway and lead author of the Science Advances study, which reported the detection.
      Picking the right aurora
      On Earth, auroras form when solar particles interact with the global magnetic field, funneling them to the poles where they collide with atmospheric gases and emit light. The most common color, green, is caused by excited oxygen atoms emitting light at a wavelength of 557.7 nanometers. For years, scientists have theorized that green light auroras could also exist on Mars but suggested they would be much fainter and harder to capture than the green auroras we see on Earth.
      Due to the Red Planet’s lack of a global magnetic field, Mars has different types of auroras than those we have on Earth. One of these is solar energetic particle (SEP) auroras, which NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) mission discovered in 2014. These occur when super-energetic particles from the Sun hit the Martian atmosphere, causing a reaction that makes the atmosphere glow across the whole night sky.
      While MAVEN had observed SEP auroras in ultraviolet light from orbit, this phenomenon had never been observed in visible light from the ground. Since SEPs typically occur during solar storms, which increase during solar maximum, Knutsen and her team set their sights on capturing visible images and spectra of SEP aurora from Mars’ surface at the peak of the Sun’s current solar cycle.
      Coordinating the picture-perfect moment
      Through modeling, Knutsen and her team determined the optimal angle for the Perseverance rover’s SuperCam spectrometer and Mastcam-Z camera to successfully observe the SEP aurora in visible light. With this observation strategy in place, it all came down to the timing and understanding of CMEs.
      “The trick was to pick a good CME, one that would accelerate and inject many charged particles into Mars’ atmosphere,” said Knutsen.
      That is where the teams at NASA’s Moon to Mars (M2M) Space Weather Analysis Office and the Community Coordinated Modeling Center (CCMC), both located at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, came in. The M2M team provides real-time analysis of solar eruptions to the CCMC for initiating simulations of CMEs to determine if they might impact current NASA missions. When the simulations suggest potential impacts, the team sends out an alert.
      At the University of California, Berkeley, space physicist Christina Lee received an alert from the M2M office about the March 15, 2024, CME. Lee, a member of the MAVEN mission team who serves as the space weather lead, determined there was a notable solar storm heading toward the Red Planet,which could arrive in a few days. She immediately issued the Mars Space Weather Alert Notification to currently operating Mars missions.
      “This allows the science teams of Perseverance and MAVEN to anticipate impacts of interplanetary CMEs and the associated SEPs,” said Lee.
      “When we saw the strength of this one,” Knutsen said, “we estimated it could trigger aurora bright enough for our instruments to detect.”
      A few days later, the CME impacted Mars, providing a lightshow for the rover to capture, showing the aurora to be nearly uniform across the sky at an emission wavelength of exactly 557.7 nm. To confirm the presence of SEPs during the aurora observation, the team looked to MAVEN’s SEP instrument, which was additionally corroborated by data from ESA’s (European Space Agency) Mars Express mission. Data from both missions confirmed that the rover team had managed to successfully catch a glimpse of the phenomenon in the very narrow time window available.
      “This was a fantastic example of cross-mission coordination. We all worked together quickly to facilitate this observation and are thrilled to have finally gotten a sneak peek of what astronauts will be able to see there some day,” said Shannon Curry, MAVEN principal investigator and research scientist at the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder (CU Boulder).
      The future of aurora on Mars
      By coordinating the Perseverance observations with measurements from MAVEN’s SEP instrument, the teams could help each other determine that the observed 557.7 nm emission came from solar energetic particles. Since this is the same emission line as the green aurora on Earth, it is likely that future Martian astronauts would be able to see this type of aurora.
      “Perseverance’s observations of the visible-light aurora confirm a new way to study these phenomena that’s complementary to what we can observe with our Mars orbiters,” said Katie Stack Morgan, acting project scientist for Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. “A better understanding of auroras and the conditions around Mars that lead to their formation are especially important as we prepare to send human explorers there safely.”
      On September 21, 2014, NASA’s MAVEN (Mars Atmosphere and Volatile EvolutioN) spacecraft entered orbit around Mars. The mission has produced a wealth of data about how Mars’ atmosphere responds to the Sun and solar wind NASA/JPL-Caltech More About Perseverance and MAVEN
      The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program portfolio and NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.
      The MAVEN mission, also part of NASA’s Mars Exploration Program portfolio, is led by LASP at CU Boulder. It’s managed by NASA’s Goddard Space Flight Center and was built and operated by Lockheed Martin Space, with navigation and network support from NASA’s JPL.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      New research suggests vast surface features on Venus called coronae continue to be shaped by tectonic processes. Observations of these features from NASA’s Magellan mission include, clockwise from top left, Artemis Corona, Quetzalpetlatl Corona, Bahet Corona, and Aine Corona.NASA/JPL-Caltech Using archival data from the mission, launched in 1989, researchers have uncovered new evidence that tectonic activity may be deforming the planet’s surface.
      Vast, quasi-circular features on Venus’ surface may reveal that the planet has ongoing tectonics, according to new research based on data gathered more than 30 years ago by NASA’s Magellan mission. On Earth, the planet’s surface is continually renewed by the constant shifting and recycling of massive sections of crust, called tectonic plates, that float atop a viscous interior. Venus doesn’t have tectonic plates, but its surface is still being deformed by molten material from below.
      Seeking to better understand the underlying processes driving these deformations, the researchers studied a type of feature called a corona. Ranging in size from dozens to hundreds of miles across, a corona is most often thought to be the location where a plume of hot, buoyant material from the planet’s mantle rises, pushing against the lithosphere above. (The lithosphere includes the planet’s crust and the uppermost part of its mantle.) These structures are usually oval, with a concentric fracture system surrounding them. Hundreds of coronae are known to exist on Venus.
      Published in the journal Science Advances, the new study details newly discovered signs of activity at or beneath the surface shaping many of Venus’ coronae, features that may also provide a unique window into Earth’s past. The researchers found the evidence of this tectonic activity within data from NASA’s Magellan mission, which orbited Venus in the 1990s and gathered the most detailed gravity and topography data on the planet currently available.
      “Coronae are not found on Earth today; however, they may have existed when our planet was young and before plate tectonics had been established,” said the study’s lead author, Gael Cascioli, assistant research scientist at the University of Maryland, Baltimore County, and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “By combining gravity and topography data, this research has provided a new and important insight into the possible subsurface processes currently shaping the surface of Venus.”
      This artist’s concept of the large Quetzalpetlatl Corona located in Venus’ southern hemisphere depicts active volcanism and a subduction zone, where the foreground crust plunges into the planet’s interior. A new study suggests coronae are the locations of several types of tectonic activity.NASA/JPL-Caltech/Peter Rubin As members of NASA’s forthcoming VERITAS (Venus Emissivity, Radio science, InSAR, Topography, and Spectroscopy) mission, Cascioli and his team are particularly interested in the high-resolution gravity data the spacecraft will provide. Study coauthor Erwan Mazarico, also at Goddard, will co-lead the VERITAS gravity experiment when the mission launches no earlier than 2031.
      Mystery Coronae
      Managed by NASA’s Jet Propulsion Laboratory in Southern California, Magellan used its radar system to see through Venus’ thick atmosphere and map the topography of its mountains and plains. Of the geological features the spacecraft mapped, coronae were perhaps the most enigmatic: It wasn’t clear how they formed. In the years since, scientists have found many coronae in locations where the planet’s lithosphere is thin and heat flow is high.
      “Coronae are abundant on Venus. They are very large features, and people have proposed different theories over the years as to how they formed,” said coauthor Anna Gülcher, Earth and planetary scientist at the University of Bern in Switzerland. “The most exciting thing for our study is that we can now say there are most likely various and ongoing active processes driving their formation. We believe these same processes may have occurred early in Earth’s history.”
      The researchers developed sophisticated 3D geodynamic models that demonstrate various formation scenarios for plume-induced coronae and compared them with the combined gravity and topography data from Magellan. The gravity data proved crucial in helping the researchers detect less dense, hot, and buoyant plumes under the surface — information that couldn’t be discerned from topography data alone. Of the 75 coronae studied, 52 appear to have buoyant mantle material beneath them that is likely driving tectonic processes.
      One key process is subduction: On Earth, it happens when the edge of one tectonic plate is driven beneath the adjacent plate. Friction between the plates can generate earthquakes, and as the old rocky material dives into the hot mantle, the rock melts and is recycled back to the surface via volcanic vents.
      These illustrations depict various types of tectonic activity thought to persist beneath Venus’ coronae. Lithospheric dripping and subduction are shown at top; below are and two scenarios where hot plume material rises and pushes against the lithosphere, potentially driving volcanism above it.Anna Gülcher, CC BY-NC On Venus, a different kind of subduction is thought to occur around the perimeter of some coronae. In this scenario, as a buoyant plume of hot rock in the mantle pushes upward into the lithosphere, surface material rises and spreads outward, colliding with surrounding surface material and pushing that material downward into the mantle.
      Another tectonic process known as lithospheric dripping could also be present, where dense accumulations of comparatively cool material sink from the lithosphere into the hot mantle. The researchers also identify several places where a third process may be taking place: A plume of molten rock beneath a thicker part of the lithosphere potentially drives volcanism above it.
      Deciphering Venus
      This work marks the latest instance of scientists returning to Magellan data to find that Venus exhibits geologic processes that are more Earth-like than originally thought. Recently, researchers were able to spot erupting volcanoes, including vast lava flows that vented from Maat Mons, Sif Mons, and Eistla Regio in radar images from the orbiter.
      While those images provided direct evidence of volcanic action, the authors of the new study will need sharper resolution to draw a complete picture about the tectonic processes driving corona formation. “The VERITAS gravity maps of Venus will boost the resolution by at least a factor of two to four, depending on location — a level of detail that could revolutionize our understanding of Venus’ geology and implications for early Earth,” said study coauthor Suzanne Smrekar, a planetary scientist at JPL and principal investigator for VERITAS.
      Managed by JPL, VERITAS will use a synthetic aperture radar to create 3D global maps and a near-infrared spectrometer to figure out what the surface of Venus is made of.  Using its radio tracking system, the spacecraft will also measure the planet’s gravitational field to determine the structure of Venus’ interior. All of these instruments will help pinpoint areas of activity on the surface.

      For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. The full artist’s concept illustration and full caption is shown below. Credits:
      NASA, ESA, CSA, Ralf Crawford (STScI) Is frozen water scattered in systems around other stars? Astronomers have long expected it is, partially based on previous detections of its gaseous form, water vapor, and its presence in our own solar system.
      Now there is definitive evidence: Researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star 155 light-years away using detailed data known as spectra from NASA’s James Webb Space Telescope. (The term water ice specifies its makeup, since many other frozen molecules are also observed in space, such as carbon dioxide ice, or “dry ice.”) In 2008, data from NASA’s retired Spitzer Space Telescope hinted at the possibility of frozen water in this system.
      “Webb unambiguously detected not just water ice, but crystalline water ice, which is also found in locations like Saturn’s rings and icy bodies in our solar system’s Kuiper Belt,” said Chen Xie, the lead author of the new paper and an assistant research scientist at Johns Hopkins University in Baltimore, Maryland.
      All the frozen water Webb detected is paired with fine dust particles throughout the disk — like itsy-bitsy “dirty snowballs.” The results published Wednesday in the journal Nature.
      Astronomers have been waiting for this definitive data for decades. “When I was a graduate student 25 years ago, my advisor told me there should be ice in debris disks, but prior to Webb, we didn’t have instruments sensitive enough to make these observations,” said Christine Chen, a co-author and associate astronomer at the Space Telescope Science Institute in Baltimore. “What’s most striking is that this data looks similar to the telescope’s other recent observations of Kuiper Belt objects in our own solar system.”
      Water ice is a vital ingredient in disks around young stars — it heavily influences the formation of giant planets and may also be delivered by small bodies like comets and asteroids to fully formed rocky planets. Now that researchers have detected water ice with Webb, they have opened the door for all researchers to study how these processes play out in new ways in many other planetary systems.
      Image: Debris Disk Around Star HD 181327 (Artist’s Concept)
      For the first time, researchers confirmed the presence of crystalline water ice in a dusty debris disk that orbits a Sun-like star, using NASA’s James Webb Space Telescope. All the frozen water detected by Webb is paired with fine dust particles throughout the disk. The majority of the water ice observed is found where it’s coldest and farthest from the star. The closer to the star the researchers looked, the less water ice they found. NASA, ESA, CSA, Ralf Crawford (STScI) Rocks, Dust, Ice Rushing Around
      The star, cataloged HD 181327, is significantly younger than our Sun. It’s estimated to be 23 million years old, compared to the Sun’s more mature 4.6 billion years. The star is slightly more massive than the Sun, and it’s hotter, which led to the formation of a slightly larger system around it.
      Webb’s observations confirm a significant gap between the star and its debris disk — a wide area that is free of dust. Farther out, its debris disk is similar to our solar system’s Kuiper Belt, where dwarf planets, comets, and other bits of ice and rock are found (and sometimes collide with one another). Billions of years ago, our Kuiper Belt was likely similar to this star’s debris disk.
      “HD 181327 is a very active system,” Chen said. “There are regular, ongoing collisions in its debris disk. When those icy bodies collide, they release tiny particles of dusty water ice that are perfectly sized for Webb to detect.”
      Frozen Water — Almost Everywhere
      Water ice isn’t spread evenly throughout this system. The majority is found where it’s coldest and farthest from the star. “The outer area of the debris disk consists of over 20% water ice,” Xie said.
      The closer in the researchers looked, the less water ice they found. Toward the middle of the debris disk, Webb detected about 8% water ice. Here, it’s likely that frozen water particles are produced slightly faster than they are destroyed. In the area of the debris disk closest to the star, Webb detected almost none. It’s likely that the star’s ultraviolet light vaporizes the closest specks of water ice. It’s also possible that rocks known as planetesimals have “locked up” frozen water in their interiors, which Webb can’t detect.
      This team and many more researchers will continue to search for — and study — water ice in debris disks and actively forming planetary systems throughout our Milky Way galaxy. “The presence of water ice helps facilitate planet formation,” Xie said. “Icy materials may also ultimately be ‘delivered’ to terrestrial planets that may form over a couple hundred million years in systems like this.”
      The researchers observed HD 181327 with Webb’s NIRSpec (Near-Infrared Spectrograph), which is super-sensitive to extremely faint dust particles that can only be detected from space.
      The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

      Do you dream of working for NASA and contributing to exploration and innovation for the benefit of humanity? The agency’s internship programs provide high school and college students opportunities to advance NASA’s mission in aeronautics, science, technology, and space.  
      Claudia Sales, Kassidy McLaughlin, and Julio Treviño started their careers as interns at NASA’s Armstrong Flight Research Center in Edwards, California, where they continue to explore the secrets of the universe. Their journeys highlight the long-term impact of the NASA’s science, technology, engineering, and mathematics (STEM) programs.

      “I knew since I was a child that I wanted to work for NASA,” said Claudia Sales, acting X-59 deputy chief engineer X-59 deputy chief engineer and airworthiness certification lead for the agency’s quiet supersonic research aircraft.
      Sales’ journey at NASA started in 2005 as a Pathways intern, a NASA work-study (co-op) program. She worked in propulsion and structures branches and supported such projects as the X-43A hypersonic research aircraft (Hyper-X) and the X-37 reusable orbital launch vehicle, where she had the opportunity to perform calculations for thermal estimations and trajectory analyses. She also completed design work with NASA Armstrong’s Experimental Fabrication Shop.
      “It had been a dream of mine to be a part of unique, one-of-a-kind flight research projects,” Sales said. “My mentor was amazing at exposing me to a wide variety of experiences and working on something unique to one day be implemented on an air vehicle to make the world a better place.”

      Similarly, flight systems engineer Kassidy McLaughlin discovered that mentorship and hands-on experience as an intern were key to her professional development. She currently leads the development of a ground control station at NASA Armstrong.
      In high school and college, McLaughlin enrolled in STEM classes, knowing she wanted to pursue a career in engineering. Encouraged by her mother to apply for a NASA internship, McLaughlin’s career began in 2014 as an intern for NASA Armstrong’s Office of STEM Engagement. She later transitioned to the Pathways program.
      “My mentor gave me the tools necessary, and encouraged me to ask questions,” McLaughlin said. “He helped show me that I was capable of anything if I set my mind to it.”
      During five rotations as an intern, she worked on the Unmanned Aircraft Systems Integration in the National Airspace System (UAS in the NAS) project. “It is such a rewarding feeling to be in a control room when something you have worked on is flying,” McLaughlin said. That experience inspired her to pursue a career in mechanical engineering.
      “NASA Armstrong offered something special when it came to the people,” McLaughlin said. “The culture at the center is so friendly and everyone is so welcoming.”

      Julio Treviño, lead operations engineer for NASA’s Global Hawk SkyRange project, ensures airworthiness throughout the planning, integration, and flight phases of unique systems and vehicles. He is also a certified mission controller, mission director, and flight test engineer for various agency aircraft.
      Much like McLaughlin, Treviño began his journey in 2018 as a Pathway’s intern for the Dynamic and Controls branch at NASA Armstrong. That experience paved the way for success after graduating with a degree in mechanical engineering.
      “As an intern, I had the opportunity to work on designing and creating a battery model for an all-electric aircraft,” Treviño said. “It was officially published as a NASA software model for use by anyone throughout the agency.”
      Treviño also credits NASA’s culture and people as the best part of his internship. “I had very supportive mentors throughout my time as an intern and the fact that everyone here genuinely loves the work that they do is awesome,” he said.
      2025 Application Deadlines
      Every year, NASA provides more than 2,000 students the opportunity to impact the agency’s mission through hands-on internships. The 2025 application for fall is May 16, 2025.
