Of all the possible entry points to NASA, the agency’s SkillBridge Program has been instrumental in helping servicemembers transition from the military and into civilian careers. Offered in partnership with the Department of Defense (DoD), the program enables individuals to spend their final months of military service working with a NASA office or organization. SkillBridge fellows work anywhere from 90 to 180 days, contributing their unique skillsets to the agency while building their network and knowledge.
The Johnson Space Center in Houston hosted NASA’s first SkillBridge fellow in 2019, paving the way for dozens of others to follow. SkillBridge participants are not guaranteed a job offer at the end of their fellowship, but many have gone on to accept full-time positions with NASA. About 25 of those former fellows currently work at Johnson, filling roles as varied as their military experiences.

He ended his 30 years of service as the administration, academics, and operations chief for the Marine Corps University in Quantico, Virginia, where he was also an adjunct professor. Shears completed a SkillBridge fellowship with FOD in the summer and fall of 2023, supporting the instructional systems design team. He was hired as a full-time employee upon his military retirement and currently serves as an instructional systems designer for the Instructor Training Module, Mentorship Module, and Spaceflight Academy. He conducts training needs analysis for FOD, as well.

He spent the last three of his nearly 24-year Air Force career serving as the deputy director of the DoD Human Spaceflight Payloads Office at Johnson. His team oversaw the development, integration, launch, and operation of payloads hosting DoD experiments on small satellites and the International Space Station. He also became a certified capsule communicator, or capcom, in December 2022, and was the lead capcom for SpaceX’s 28th commercial resupply services mission to the orbiting laboratory.
Zavala’s SkillBridge fellowship was in Johnson’s Astronaut Office, where he worked as a capcom, capcom instructor, and an integration engineer supporting the Extravehicular Activity and Human Surface Mobility Program. He was involved in developing a training needs analysis and agency simulators for the human landing system, among other projects.
He officially joined the center team as a full-time contractor in August 2024. He is currently a flight operations safety officer within the Flight Operations Directorate (FOD) and continues to serve as a part-time capcom.

Images courtesy of Carl Johnson Carl Johnson thanks his wife for helping him find a path to NASA. While she was a Pathways intern — and his girlfriend at the time — she gave him a tour of the center that inspired him to join the agency when he was ready to leave the Army. She helped connect him to one of the center’s SkillBridge coordinators and the rest is history.
Johnson was selected for a SkillBridge fellowship in the Dynamic System Test Branch. From February to June 2023, he supported development of the lunar terrain vehicle ground test unit and contributed to the Active Response Gravity Offload System (ARGOS), which simulates reduced gravity for astronaut training.
Johnson officially joined the center team as an electrical engineer in the Engineering Directorate’s Software, Robotics, and Simulation Division in September 2023. He is currently developing a new ARGOS spacewalk simulator and training as an operator and test director for another ARGOS system.
Johnson holds an electrical engineering degree from the United States Military Academy. He was on active duty in the Army for 10 years and concluded his military career as an instructor and small group leader for the Engineer Captains Career Course. In that role, he was responsible for instructing, mentoring, and preparing the next generation of engineer captains.

His last role was maintenance senior chief with Air Test and Evaluation Squadron 31, known as “the Dust Devils.” Quinn managed the operations and maintenance of 33 aircraft, ensuring their readiness for complex missions and contributing to developmental flight tests and search and rescue missions. He applied that experience to his SkillBridge fellowship in quality assurance at Ellington Field in 2024. Quinn worked to enhance flight safety and astronaut training across various aircraft, including the T-38, WB-57, and the Super Guppy. He has continued contributing to those projects since being hired as a full-time quality assurance employee in 2025.

Image courtesy of Andrew Ulat Andrew Ulat retired from the Air Force after serving for 21 years as an intercontinental ballistic missile launch control officer and strategic operations advisor. His last role in the military was as a director of staff at the Air Command and Staff College at Maxwell Air Force Base in Montgomery, Alabama. There he served as a graduate-level instructor teaching international security concepts to mid-level officers and civilian counterparts from all branches of the military and various federal agencies.
Ulat started his SkillBridge fellowship as an integration engineer in Johnson’s X-Lab, supporting avionics, power, and software integration for the Gateway lunar space station. Ulat transitioned directly from his fellowship into a similar full-time position at Johnson in May 2024.
Ariel Vargas receives a commendation during his Army service (left) and in his official NASA portrait. Ariel Vargas transitioned to NASA after serving for five years in the Army. His last role in the military was as a signal officer, which involved leading teams managing secure communications and network operations in dynamic and mission-critical environments in the Middle East and the United States.
Vargas completed his SkillBridge fellowship in November 2023, supporting Johnson’s Office of the Chief Information Officer (OCIO). During his fellowship, he led a center-wide wireless augmentation project that modernized Johnson’s connectivity.
He became a full-time civil servant in May 2024 and currently serves as the business operations and partnerships lead within OCIO, supporting a digital transformation initiative. In this role, he leads efforts to streamline internal business operations, manage strategic partnerships, and drive cross-functional collaboration.
“My time in the military taught me the value of service, leadership, and adaptability—qualities that I now apply daily in support of NASA’s mission,” Vargas said. “I’m proud to be part of the Johnson team and hope my story can inspire other service members considering the SkillBridge pathway.”

The catalog is part of NASA’s effort to place advanced technologies, including agency software, into the hands of businesses, researchers, and entrepreneurs to foster economic growth and innovation.
Agency developers will provide more information about the Software Catalog, the only repository of its kind in the federal government, during NASA’s summer software webinar series beginning Tuesday, July 22.
“NASA has droves of talented experts creating software to automate elements of agency missions,” said Dan Lockney, program executive, Technology Transfer at NASA Headquarters in Washington. “The resulting efficiency benefits humankind, and its public value increases exponentially when the agency provides access to those software programs for companies, enabling them to save time and money, improve commercial offerings, and build their businesses.”
The four webinars accompanying this year’s NASA Software Catalog feature developers of popular programs for mission planning, systems design, propulsion analysis, and more, each consisting of a presentation followed by a live question-and-answer session.
Programs offered in NASA’s 2025-2026 Software Catalog are grouped into 15 categories that may be useful for organizations working with spacecraft and aircraft. For example, the Vehicle Management category includes a tool for designing satellite constellations and a software library for minimizing public safety risks around expendable launch vehicles. The Aeronautics section includes several programs that are widely used by industry for creating, modifying, and analyzing aircraft designs.
Although the categories have specific themes, the codes are meant to be useful to various innovators. Companies can use aircraft programs NASA wrote to design cars, trucks, and countless other products. The catalog’s Business Systems and Project Management section includes software for estimating project costs, building and assessing complex schedules, and uncovering root causes of mishaps. Other popular programs support 3D rendering for simulation and virtual reality, bring hyper-accuracy to GPS tracking, and analyze electrical power system architectures.
NASA released its first Software Catalog more than a decade ago in 2013, and since then, the agency’s annual rate of software downloads has skyrocketed, reaching up to 5,722 downloads in a single year.
The Software Catalog is a product of NASA’s Technology Transfer program, managed by the agency’s Space Technology Mission Directorate. NASA routinely makes improvements to the Software Catalog website, ensuring the process is fast and easy. Access restrictions apply to some software that may be limited to use by U.S. citizens or for U.S. government purposes only.

6 Min Read NASA’s TRACERS Studies Explosive Process in Earth’s Magnetic Shield
High above us, particles from the Sun hurtle toward Earth, colliding with the upper atmosphere and creating powerful explosions in a murky process called magnetic reconnection. A single magnetic reconnection event can release as much energy as the entire United States uses in a day.
NASA’s new TRACERS (Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites) mission will study magnetic reconnection, answering key questions about how it shapes the impacts of the Sun and space weather on our daily lives.

NASA’s TRACERS mission, or the Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites, will fly in low Earth orbit through the polar cusps, funnel-shaped holes in the magnetic field, to study magnetic reconnection and its effects in Earth’s atmosphere. NASA’s Goddard Space Flight Center The TRACERS spacecraft are slated to launch no earlier than late July 2025 aboard a SpaceX Falcon 9 rocket from Space Launch Complex 4 East at Vandenberg Space Force Base in California. The two TRACERS spacecraft will orbit Earth to study how the solar wind — a continuous outpouring of electrically charged particles from the Sun — interacts with Earth’s magnetic shield, the magnetosphere.
What Is Magnetic Reconnection?
As solar wind flows out from the Sun, it carries the Sun’s embedded magnetic field out across the solar system. Reaching speeds over one million miles per hour, this soup of charged particles and magnetic field plows into planets in its path.
“Earth’s magnetosphere acts as a protective bubble that deflects the brunt of the solar wind’s force. You can think of it as a bar magnet that’s rotating and floating around in space,” said John Dorelli, TRACERS mission science lead at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “As the solar wind collides with Earth’s magnetic field, this interaction builds up energy that can cause the magnetic field lines to snap and explosively fling away nearby particles at high speeds — this is magnetic reconnection.”
Openings in Earth’s magnetic field at the North and South Poles, called polar cusps, act as funnels allowing charged particles to stream down towards Earth and collide with atmospheric gases. These phenomena are pieces of the space weather system that is in constant motion around our planet — whose impacts range from breathtaking auroras to disruption of communications systems and power grids. In May 2024, Earth experienced the strongest geomagnetic storm in over 20 years, which affected high-voltage power lines and transformers, forced trans-Atlantic flights to change course, and caused GPS-guided tractors to veer off-course.
How Will TRACERS Study Magnetic Reconnection?
The TRACERS mission’s twin satellites, each a bit larger than a washing machine, will fly in tandem, one behind the other, in a relatively low orbit about 360 miles above Earth. Traveling over 16,000 mph, each satellite hosts a suite of instruments to measure different aspects of extremely hot, ionized gas called plasma and how it interacts with Earth’s magnetosphere.
An artist’s concept of the twin TRACERS satellites in orbit above Earth. NASA’s Goddard Space Flight Center The satellites will focus where Earth’s magnetic field dips down to the ground at the North polar cusp. By placing the twin TRACERS satellites in a Sun-synchronous orbit, they always pass through Earth’s dayside polar cusp, studying thousands of reconnection events at these concentrated areas.
This will build a step-by-step picture of how magnetic reconnection changes over time and from Earth’s dayside to its nightside.
NASA’s TRICE-2 mission also studied magnetic reconnection near Earth, but with a pair of sounding rockets launched into the northern polar cusp over the Norwegian Sea in 2018.
“The TRICE mission took great data. It took a snapshot of the Earth system in one state. It proved that these instruments could make this kind of measurement and achieve this kind of science,” said David Miles, TRACERS principal investigator at the University of Iowa. “But the system’s more complicated than that. The TRACERS mission demonstrates how you can use multi-spacecraft technology to get a picture of how things are moving and evolving.”

Since previous missions could only take one measurement of an event per launch, too many changes in the region prevented forming a full picture. Following each other closely in orbit, the twin TRACERS satellites will provide multiple snapshots of the same area in rapid succession, spaced as closely as 10 seconds apart from each other, reaching a record-breaking 3,000 measurements in one year. These snapshots will build a picture of how the whole Earth system behaves in reaction to space weather, allowing scientists to better understand how to predict space weather in the magnetosphere.
Working Across Missions in Solar Harmony
The TRACERS mission will collaborate with other NASA heliophysics missions, which are strategically placed near Earth and across the solar system. At the Sun, NASA’s Parker Solar Probe closely observes our closest star, including magnetic reconnection there and its role in heating and accelerating the solar wind that drives the reconnection events investigated by TRACERS.
Data from recently launched NASA missions, EZIE (Electrojet Zeeman Imaging Explorer), studying electrical currents at Earth’s nightside, and PUNCH (Polarimeter to Unify the Corona and Heliosphere) studying the solar wind and interactions in Earth’s atmosphere, can be combined with observations from TRACERS. With research from these missions, scientists will be able to get a more complete understanding of how and when Earth’s protective magnetic shield can suddenly connect with solar wind, allowing the Sun’s material into Earth’s system.
“The TRACERS mission will be an important addition to NASA’s heliophysics fleet.” said Reinhard Friedel, TRACERS program scientist at NASA Headquarters in Washington. “The missions in the fleet working together increase understanding of our closest star to improve our ability to understand, predict, and prepare for space weather impacts on humans and technology in space.”
The TRACERS mission is led by David Miles at the University of Iowa with support from the Southwest Research Institute in San Antonio, Texas. NASA’s Heliophysics Explorers Program Office at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the mission for the agency’s Heliophysics Division at NASA Headquarters in Washington. The University of Iowa, Southwest Research Institute, University of California, Los Angeles, and the University of California, Berkeley, all lead instruments on TRACERS that study changes in the magnetic field and electric field. NASA’s Launch Services Program, based at the agency’s Kennedy Space Center in Florida, manages the VADR (Venture-class Acquisition of Dedicated and Rideshare) contract.

NASA Citizen Science and Your Career: Stories of Exoplanet Watch Volunteers
Doing NASA Science brings many rewards. But can taking part in NASA citizen science help your career? To find out, we asked participants in NASA’s Exoplanet Watch project about their experiences. In this project, amateur astronomers work together with professionals to track planets around other stars.
First, we heard from professional software programmers. Right away, one of them told us about getting a new job through connections made in the project.
“I decided to create the exoplanet plugin, [for citizen science] since it was quite a lot of manual work to check which transits were available for your location. The exoplanet plugin and its users got me in contact with the Stellar group… Through this group, I got into contact with a company called OurSky and started working for them… the point is, I created a couple of plugins for free and eventually got a job at an awesome company.”
Another participant talked about honing their skills and growing their confidence through Exoplanet Watch.
“There were a few years when I wasn’t actively coding. However, Exoplanet Watch rekindled that spark…. Participating in Exoplanet Watch even gave me the confidence to prepare again for a technical interview at Meta—despite having been thoroughly defeated the first time I tried.”
Teachers and teaching faculty told us how Exoplanet Watch gives them the ability to better convey what scientific research is all about – and how the project motivates students!
“Exoplanet Watch makes it easy for undergraduate students to gain experience in data science and Python, which are absolutely necessary for graduate school and many industry jobs.”
“Experience with this collaborative work is a vital piece of the workforce development of our students who are seeking advanced STEM-related careers or ongoing education in STEM (Science, Technology, Engineering, & Mathematics) fields after graduation… Exoplanet Watch, in this way, is directly training NASA’s STEM workforce of tomorrow by allowing CUNY (The City University of New York) students to achieve the science goals that would otherwise be much more difficult without its resources.”
One aspiring academic shared how her participation on the science team side of the project has given her research and mentorship experience that strengthens her resume.
“I ended up joining the EpW team to contribute my expertise in stellar variability… My involvement with Exoplanet Watch has provided me with invaluable experience in mentoring a broad range of astronomy enthusiasts and working in a collaborative environment with people from around the world. … Being able to train others, interact in a team environment, and work independently are all critical skills in any work environment, but these specific experiences have also been incredibly valuable towards building my portfolio as I search for faculty positions around the USA.”
There are no guarantees, of course. What you get out of NASA citizen science depends on what you put in. But there is certainly magic to be found in the Exoplanet Watch project. As one student said:
“Help will always be found at Hogwarts, to those who need it.” Exoplanet Watch was definitely Hogwarts for me in my career as an astronomer!”
For more information about NASA and your career, check out NASA’s Surprisingly STEM series highlighting exciting and unexpected jobs at NASA, or come to NASA Career Day, a virtual event for students and educators. Participants must register by September 4, 2025. The interactive platform will be open from September 15-19, with live panels and events taking place on September 18.
