Dwayne Lavigne works as a controls engineer at NASA’s Stennis Space Center, where he supports NASA’s Artemis mission by programming specialized computers for engine testing.NASA/Danny Nowlin As a controls engineer at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, Dwayne Lavigne does not just fix problems – he helps put pieces together at America’s largest rocket propulsion test site.
“There are a lot of interesting problems to solve, and they are never the same,” Lavigne said. “Sometimes, it is like solving a very cool puzzle and can be pretty satisfying.”
Lavigne programs specialized computers called programmable logic controllers. They are extremely fast and reliable for automating precisely timed operations during rocket engine tests as NASA Stennis supports the agency’s Artemis missions to explore the Moon and build the foundation for the first crewed mission to Mars.
However, the system will not act unless certain parameters are met in the proper sequence. It can be a complex relationship. Sometimes, 20 or 30 things must be in the correct configuration to perform an operation, such as making a valve open or close, or turning a motor on or off.
The Picayune, Mississippi, native is responsible for establishing new signal paths between test hardware and the specialized computers.
He also develops the human machine interface for the controls. The interface is a screen graphic that test engineers use to interact with hardware.
Lavigne has worked with NASA for more than a decade. One of his proudest work moments came when he contributed to development of an automated test sequencing routine used during all RS-25 engine tests on the Fred Haise Test Stand.
“We’ve had many successful tests over the years, and each one is a point of pride,” he said.
When Lavigne works on the test stand, he works with the test hardware and interacts with technicians and engineers who perform different tasks than he does. It provides an appreciation for the group effort it takes to support NASA’s mission.
“The group of people I work with are driven to get the job done and get it done right,” he said.
In total, Lavigne has been part of the NASA Stennis federal city for 26 years. He initially worked as a contractor with the Naval Oceanographic Office as a data entry operator and with the Naval Research Laboratory as a software developer.
September marks 55 years since NASA Stennis became a federal city. NASA, and more than 50 companies, organizations, and agencies located onsite share in operating costs, which allows tenants to direct more of their funding to individual missions.
“Stennis has a talented workforce accomplishing many different tasks,” said Lavigne. “The three agencies I’ve worked with at NASA Stennis are all very focused on doing the job correctly and professionally. In all three agencies, people realize that lives could be at risk if mistakes are made or shortcuts are taken.”

La NASA estrenó el martes el primer episodio de la tercera temporada de Universo curioso de la NASA, el único pódcast en español de la agencia.
Los episodios se centran en algunas de las principales misiones y temas de investigación de la NASA para 2025, llevando la maravilla de la exploración, la tecnología espacial y los descubrimientos científicos al público de habla hispana de todo el mundo.
“La ciencia de la NASA está literalmente en todas partes, y trasciende la geografía y los idiomas para ofrecer beneficios, en tiempo real, en la vida cotidiana de las personas de todo el mundo que utilizan nuestras innovaciones, datos y descubrimientos científicos alcanzados desde el punto de vista único del espacio”, dijo la doctora Nicky Fox, administradora asociada de la Dirección de Misiones Científicas, en la sede central de la NASA en Washington. “El pódcast Universo curioso de la NASA comparte los descubrimientos de la NASA con las comunidades de habla hispana de todo el mundo, inspirando a futuros exploradores a unirse a nuestro viaje mientras regresamos a la Luna y nos aventuramos hacia Marte en beneficio de toda la humanidad”.
Todos los meses se presentarán nuevos episodios hasta el final del año. El primer episodio, centrado en los objetivos científicos de la misión a la Luna Artemis II de la NASA, está disponible en:
https://go.nasa.gov/4l9lmbN
Universo curioso es presentado por Noelia González, especialista en comunicaciones en el Centro de Vuelo Espacial Goddard de la NASA en Greenbelt, Maryland. Esta temporada tendrá al coanfitrión Andrés Almeida, escritor técnico y anfitrión del pódcast de la NASA Small Steps, Giant Leaps (Pasos pequeños, grandes saltos) en la sede central de la NASA. A lo largo de la temporada, los oyentes celebrarán el legado del telescopio espacial Hubble de la NASA, aprenderán sobre una próxima misión al Sol y explorarán la energía oscura y cómo la estudiará el futuro telescopio espacial Roman, entre otros temas.
Universo curioso de la NASA es una iniciativa conjunta de los programas de comunicaciones en español y audio de la agencia. La nueva temporada, así como los episodios anteriores, están disponibles en Apple Podcasts, Spotify, SoundCloud y el sitio web de la NASA.
