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.
Eclipse Ambassadors is supported by NASA under cooperative agreement award number 80NSS22M0007 and is part of NASA’s Science Activation Portfolio.

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.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Editor’s Note: The following is one of three related articles about the NASA Data Acquisition System and related efforts. Please visit Stennis News – NASA to access accompanying articles.
A blended team of NASA personnel and contractors support ongoing development and operation of the NASA Data Acquisition System at NASA’s Stennis Space Center. Team members include, left to right: Andrew Graves (NASA), Shane Cravens (Syncom Space Services), Peggi Marshall (Syncom Space Services), Nicholas Payton Karno (Syncom Space Services), Alex Elliot (NASA), Kris Mobbs (NASA), Brandon Carver (NASA), Richard Smith (Syncom Space Services), and David Carver (NASA)NASA/Danny Nowlin Members of the NASA Data Acquisition System team at NASA’s Stennis Space Center evaluate system hardware for use in monitoring and collecting propulsion test data at the site.NASA/Danny Nowlin NASA software engineer Alex Elliot, right, and Syncom Space Services software engineer Peggi Marshall fine-tune data acquisition equipment at NASA’s Stennis Space Center by adjusting an oscilloscope to capture precise measurements. NASA/Danny Nowlin Syncom Space Services software test engineer Nicholas Payton Karno monitors a lab console at NASA’s Stennis Space Center displaying video footage of an RS-25 engine gimbal test, alongside data acquisition screens showing lab measurements. NASA/Danny Nowlin Just as a steady heartbeat is critical to staying alive, propulsion test data is vital to ensure engines and systems perform flawlessly.
The accuracy of the data produced during hot fire tests at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, tells the performance story.
So, when NASA needed a standardized way to collect hot fire data across test facilities, an onsite team created an adaptable software tool to do it.
“The NASA Data Acquisition System (NDAS) developed at NASA Stennis is a forward-thinking solution,” said David Carver, acting chief of the Office of Test Data and Information Management. “It has unified NASA’s rocket propulsion testing under an adaptable software suite to meet needs with room for future expansion, both within NASA and potentially beyond.”
Before NDAS, contractors conducting test projects used various proprietary tools to gather performance data, which made cross-collaboration difficult. NDAS takes a one-size-fits-all approach, providing NASA with its own system to ensure consistency.
“Test teams in the past had to develop their own software tools, but now, they can focus on propulsion testing while the NDAS team focuses on developing the software that collects data,” said Carver.
A more efficient workflow has followed since the software system is designed to work with any test hardware. It allows engineers to seamlessly work between test areas, even when upgrades have been made and hardware has changed, to support hot fire requirements for the agency and commercial customers.
With the backing and resources of the NASA Rocket Propulsion Test (RPT) Program Office, a blended team of NASA personnel and contractors began developing NDAS in 2011 as part of the agency’s move to resume control of test operations at NASA Stennis. Commercial entities had conducted the operations on NASA’s behalf for several decades.
The NASA Stennis team wrote the NDAS software code with modular components that function independently and can be updated to meet the needs of each test facility. The team used LabVIEW, a graphical platform that allows developers to build software visually rather than using traditional text-based code.

NASA/Danny Nowlin NASA engineers, from left to right, Tristan Mooney, Steven Helmstetter Chase Aubry, and Christoffer Barnett-Woods are shown in the E-1 Test Control Center where the NASA Data Acquisition System is utilized for propulsion test activities. NASA/Danny Nowlin NASA engineers Steven Helmstetter, Christoffer Barnett-Woods, and Tristan Mooney perform checkouts on a large data acquisition system for the E-1 Test Stand at NASA’s Stennis Space Center. The data acquisition hardware, which supports testing for E Test Complex commercial customers, is controlled by NASA Data Acquisition System software that allows engineers to view real-time data while troubleshooting hardware configuration.NASA/Danny Nowlin NASA engineers Steven Helmstetter, left, and Tristan Mooney work with the NASA Data Acquisition System in the E-1 Test Control Center, where the system is utilized for propulsion test activities.NASA/Danny Nowlin “These were very good decisions by the original team looking toward the future,” said Joe Lacher, a previous NASA project manager. “LabVIEW was a new language and is now taught in colleges and widely used in industry. Making the program modular made it adaptable.”
During propulsion tests, the NDAS system captures both high-speed and low-speed sensor data. The raw sensor data is converted into units for both real-time monitoring and post-test analysis.
During non-test operations, the system monitors the facility and test article systems to help ensure the general health and safety of the facility and personnel.
“Having quality software for instrumentation and data recording systems is critical and, in recent years, has become increasingly important,” said Tristan Mooney, NASA instrumentation engineer. “Long ago, the systems used less software, or even none at all. Amplifiers were configured with physical knobs, and data was recorded on tape or paper charts. Today, we use computers to configure, display, and store data for nearly everything.”
Developers demonstrated the new system on the A-2 Test Stand in 2014 for the J-2X engine test project.
From there, the team rolled it out on the Fred Haise Test Stand (formerly A-1), where it has been used for RS-25 engine testing since 2015. A year later, teams used NDAS on the Thad Cochran Test Stand (formerly B-2) in 2016 to support SLS (Space Launch System) Green Run testing for future Artemis missions.
One of the project goals for the system is to provide a common user experience to drive consistency across test complexes and centers.
Kris Mobbs, current NASA project manager for NDAS, said the system “really shined” during the core stage testing. “We ran 24-hour shifts, so we had people from across the test complex working on Green Run,” Mobbs said. “When the different shifts came to work, there was not a big transition needed. Using the software for troubleshooting, getting access to views, and seeing the measurements were very common activities, so the various teams did not have a lot of build-up time to support that test.”
Following success at the larger test stands, teams started using NDAS in the E Test Complex in 2017, first at the E-2 Test Stand, then on the E-1 and E-3 stands in 2020.
Growth of the project was “a little overwhelming,” Lacher recalled. The team maintained the software on active stands supporting tests, while also continuing to develop the software for other areas and their many unique requirements.
Each request for change had to be tracked, implemented into the code, tested in the lab, then deployed and validated on the test stands.
“This confluence of requirements tested my knowledge of every stand and its uniqueness,” said Lacher. “I had to understand the need, the effort to meet it, and then had to make decisions as to the priorities the team would work on first.”
Creation of the data system and its ongoing updates have transformed into opportunities for growth among the NASA Stennis teams working together.
“From a mechanical test operations perspective, NDAS has been a pretty easy system to learn,” said Derek Zacher, NASA test operations engineer. “The developers are responsive to the team’s ideas for improvement, and our experience has consistently improved with the changes that enable us to view our data in new ways.”
Originally designed to support the RPT office at NASA Stennis, the software is expanding beyond south Mississippi to other test centers, attracting interest from various NASA programs and projects, and garnering attention from government agencies that require reliable and scalable data acquisition. “It can be adopted nearly anywhere, such as aerospace and defense, research and development institutions and more places, where data acquisition systems are needed,” said Mobbs. “It is an ever-evolving solution.”
