      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.

      The Rocky Mountains in Colorado, as seen from the International Space Station. Snowmelt from the mountainous western United States is an essential natural resource, making up as much as 75% of some states’ annual freshwater supply. Summer heat has significant effects in the mountainous regions of the western United States. Melted snow washes from snowy peaks into the rivers, reservoirs, and streams that supply millions of Americans with freshwater—as much as 75% of the annual freshwater supply for some states.
      But as climate change brings winter temperatures to new highs, these summer rushes of freshwater can sometimes slow to a trickle.
      “The runoff supports cities most people wouldn’t expect,” explained Chris Derksen, a glaciologist and Research Scientist with Environment and Climate Change Canada. “Big cities like San Francisco and Los Angeles get water from snowmelt.”
      To forecast snowmelt with greater accuracy, NASA’s Earth Science Technology Office (ESTO) and a team of researchers from the University of Massachusetts, Amherst, are developing SNOWWI, a dual-frequency synthetic aperture radar that could one day be the cornerstone of future missions dedicated to measuring snow mass on a global scale – something the science community lacks.
      SNOWWI aims to fill this technology gap. In January and March 2024, the SNOWWI research team passed a key milestone, flying their prototype for the first time aboard a small, twin-engine aircraft in Grand Mesa, Colorado, and gathering useful data on the area’s winter snowfields.
      “I’d say the big development is that we’ve gone from pieces of hardware in a lab to something that makes meaningful data,” explained Paul Siqueira, professor of engineering at the University of Massachusetts, Amherst, and principal investigator for SNOWWI.
      SNOWWI stands for Snow Water-equivalent Wide Swath Interferometer and Scatterometer. The instrument probes snowpack with two Ku-band radar signals: a high-frequency signal that interacts with individual snow grains, and a low-frequency signal that passes through the snowpack to the ground. 
      The high-frequency signal gives researchers a clear look at the consistency of the snowpack, while the low-frequency signal helps researchers determine its total depth.
      “Having two frequencies allows us to better separate the influence of the snow microstructure from the influence of the snow depth,” said Derksen, who participated in the Grand Mesa field campaign. “One frequency is good, two frequencies are better.”

      The SNOWWI team in Grand Mesa, preparing to flight test their instrument. From an altitude of 4 kilometers (2.5 miles), SNOWWI can map 100 square kilometers (about 38 square miles) in just 30 minutes.
      As both of those scattered signals interact with the snowpack and bounce back towards the instrument, they lose energy. SNOWWI measures that lost energy, and researchers later correlate those losses to features within the snowpack, especially its depth, density, and mass.
      From an airborne platform with an altitude of 2.5 miles (4 kilometers), SNOWWI could map 40 square miles (100 square kilometers) of snowy terrain in just 30 minutes. From space, SNOWWI’s coverage would be even greater. Siqueira is working with Capella Space to develop a space-ready SNOWWI for satellite missions.
      But there’s still much work to be done before SNOWWI visits space. Siqueira plans to lead another field campaign, this time in the mountains of Idaho. Grand Mesa is relatively flat, and Siqueira wants to see how well SNOWWI can measure snowpack tucked in the folds of complex, asymmetrical terrain.
      For Derksen, who spends much of his time quantifying the freshwater content of snowpack in Canada, having a reliable database of global snowpack measurements would be game-changing.
      “Snowmelt is money. It has intrinsic economic value,” he said. “If you want your salmon to run in mountain streams in the spring, you must have snowmelt. But unlike other natural resources, at this time, we really can’t monitor it very well.”
