NASA and the military have shared strong connections since the agency’s early days. From the nation’s earliest aeronautic research and the recruitment of test pilot astronauts to modern-day technology development, satellite management, and planetary defense, NASA has built a longstanding partnership with the military.
This legacy of collaboration has created natural opportunities for former service members to join NASA’s ranks at the conclusion of their military careers.
Lewis Swain is one of the many veterans working at Johnson Space Center in Houston today. Swain was recruited by NASA contractor McDonnell Douglas after leaving the military in 1980. He commissioned as a second lieutenant and served in the Air Force for 12 years, flying nearly 200 combat missions during two tours in Vietnam.
“The shuttle program was starting, and they needed ex-military pilots to serve as simulation instructors,” he said. Swain specialized in control and propulsion systems instruction for several years before becoming the training team lead for shuttle missions. Following the Challenger accident in 1986, Swain transitioned to supporting the International Space Station Program and Return to Flight evaluations. He has been a civil servant since 1989 and a training facility manager since 2006.

Jerry Swain NASA’s Pathways Internship Program has also provided a point of entry for former service members. John Smith was studying mechanical engineering at the University of Texas at El Paso when he made an impactful Johnson connection. “I met with a former flight director, Ms. Ginger Kerrick, at a career fair hosted by my university,” he said. “Pathways happened to be accepting applications at the time and she enthusiastically encouraged me to apply. I never expected to get a response, much less an offer. I couldn’t say yes fast enough when it came!”
For others, the NASA SkillBridge Program has been instrumental in transitioning from the military to civilian careers. The program connects individuals in their final months of military service 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. Since fellows’ pay and benefits are provided by their military branch, their support comes at no additional cost to NASA.
Johnson hosted the agency’s first-ever SkillBridge fellow in spring 2019, paving the way for many others to follow. Albert Meza, an Air Force space professional, was among this first wave of service members at NASA.
Approaching retirement from the Air Force in November 2019, Meza planned to move his family back to Houston that summer, then join them in the fall once his military service ended. A colleague encouraged him to apply for SkillBridge because it would let Meza move with his family. Meza was skeptical, noting the military is not typically flexible on moves or timelines, but after a quick meeting with his commanding officer and finding a Johnson team to work with, he was on his way to Houston. “It was unbelievable,” he said. “It kind of fell into my lap.”

Walheim during his retirement ceremony at Space Center Houston (right).

In this role, he acts as a liaison between payload teams and the vendor developing a lander to help ensure flight requirements are understood and met.
Meza is also one of SkillBridge’s on-site coordinators. He said that when he first arrived at Johnson, he realized the program was relatively unknown. “I thought, I need to take the responsibility for waving the flag for SkillBridge at NASA.” Meza works tirelessly to educate service members, military leaders, and NASA supervisors about the program’s benefits. He also emphasizes how easy it is for NASA supervisors to host a fellow. “You get someone for six months who is already disciplined, loyal, and has all of these highly trained credentials,” he said. “Any civil servant supervisor can host a SkillBridge fellow. The only real requirement is that the supervisor can provide IT assets and a work location.”
Johnson has hosted more than 25 SkillBridge fellows since the program’s inception. Many fellows have since accepted full-time positions with NASA, including Patricia “Trish” Elliston. Meza found her a SkillBridge position with the center’s Protective Services Division in spring 2023. Elliston relocated to Houston in 2020, a few years prior to her anticipated retirement from the U.S. Coast Guard. Living in Houston and interacting with numerous NASA employees, along with prior experience working with the agency in maritime safety, convinced Elliston that Johnson was the place for her.

Images courtesy of Trish Elliston “During my internship I networked as much as possible and made every effort to learn as much as I could so that I could be better prepared to start my civilian career,” Elliston said. “I worked hard and learned a lot, and when a job opportunity became available, I applied.” She now works as a cyber intelligence analyst within the Flight Operations Directorate.
Meza notes that SkillBridge is a transition program, not a hiring program, and that some fellows have not received a job offer or have decided to pursue other opportunities. What happens after a SkillBridge fellowship depends on each individual and whether they’ve demonstrated their potential and built relationships in a way that turns this ‘foot in the door’ into a full-time position.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
By Wayne Smith
As NASA plans for humans to return to the Moon and eventually explore Mars, a laser beam welding collaboration between NASA’s Marshall Space Flight Center in Huntsville, Alabama, and The Ohio State University in Columbus aims to stimulate in-space manufacturing.
Scientists and engineers from NASA’s Marshall Space Flight Center, participating in the laser beam welding study in August, stand in front of the parabolic plane used for testing. From left, Will Evans, Louise Littles, Emma Jaynes, Andrew O’Connor, and Jeffrey Sowards. Not pictured: Zachary Courtright.Casey Coughlin/Starlab-George Washington Carver Science Park The multi-year effort seeks to understand the physical processes of welding on the lunar surface, such as investigating the effects of laser beam welding in a combined vacuum and reduced gravity environment. The goal is to increase the capabilities of manufacturing in space to potentially assemble large structures or make repairs on the Moon, which will inform humanity’s next giant leap of sending astronauts to Mars and beyond.
“For a long time, we’ve used fasteners, rivets, or other mechanical means to keep structures that we assemble together in space,” said Andrew O’Connor, a Marshall materials scientist who is helping coordinate the collaborative effort and is NASA’s technical lead for the project. “But we’re starting to realize that if we really want strong joints and if we want structures to stay together when assembled on the lunar surface, we may need in-space welding.” The ability to weld structures in space would also eliminate the need to transport rivets and other materials, reducing payloads for space travel. That means learning how welds will perform in space.
To turn the effort into reality, researchers are gathering data on welding under simulated space conditions, such as temperature and heat transfer in a vacuum; the size and shape of the molten area under a laser beam; how the weld cross-section looks after it solidifies; and how mechanical properties change for welds performed in environmental conditions mimicking the lunar surface.
“Once you leave Earth, it becomes more difficult to test how the weld performs, so we are leveraging both experiments and computer modeling to predict welding in space while we’re still on the ground,” said O’Connor.
In August 2024, a joint team from Ohio State’s Welding Engineering and Multidisciplinary Capstone Programs and Marshall’s Materials & Processes Laboratory performed high-powered fiber laser beam welding aboard a commercial aircraft that simulated reduced gravity. The aircraft performed parabolic flight maneuvers that began in level flight, pulled up to add 8,000 feet in altitude, and pushed over at the top of a parabolic arc, resulting in approximately 20 seconds of reduced gravity to the passengers and experiments.
While floating in this weightless environment, team members performed laser welding experiments in a simulated environment similar to that of both low Earth orbit and lunar gravity. Analysis of data collected by a network of sensors during the tests will help researchers understand the effects of space environments on the welding process and welded material.
NASA Marshall engineers and scientists, along with their collaborators from Ohio State University, monitor laser beam welding in a vacuum chamber during a Boeing 727 parabolic flight. From left, Andrew O’Connor, Marshall materials scientist and NASA technical lead for the project; Louise Littles, Marshall materials scientist; and Aaron Brimmer, OSU graduate student.Tasha Dixon/Zero-G “During the flights we successfully completed 69 out of 70 welds in microgravity and lunar gravity conditions, realizing a fully successful flight campaign,” said Will McAuley, an Ohio State welding engineering student.
Funded in part by Marshall and spanning more than two years, the work involves undergraduate and graduate students and professors from Ohio State, and engineers across several NASA centers. Marshall personnel trained alongside the university team, learning how to operate the flight hardware and sharing valuable lessons from previous parabolic flight experiments. NASA’s Langley Research Center in Hampton, Virginia, developed a portable vacuum chamber to support testing efforts.
The last time NASA performed welding in space was during the Skylab mission in 1973. Other parabolic tests have since been performed, using low-powered lasers. Practical welding and joining methods and allied processes, including additive manufacturing, will be required to develop the in-space economy. These processes will repurpose and repair critical space infrastructure and could build structures too large to fit current launch payload volumes. In-space welding could expedite building large habitats in low Earth orbit, spacecraft structures that keep astronauts safe on future missions, and more.
The work is also relevant to understanding how laser beam welding occurs on Earth. Industries could use data to inform welding processes, which are critical to a host of manufactured goods from cars and refrigerators to skyscrapers.
“We’re really excited about laser beam welding because it gives us the flexibility to operate in different environments,” O’Connor said.
There has been a resurgence of interest in welding as we look for innovative ways to put larger structures on the surface of the Moon and other planets.
