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.”

On June 11, NASA’s LRO (Lunar Reconnaissance Orbiter) captured photos of the site where the ispace Mission 2 SMBC x HAKUTO-R Venture Moon (RESILIENCE) lunar lander experienced a hard landing on June 5, 2025, UTC.

LRO’s right Narrow Angle Camera (one in a suite of cameras known as LROC) captured the images featured here from about 50 miles above the surface of Mare Frigoris, a volcanic region interspersed with large-scale faults known as wrinkle ridges.
The dark smudge visible above the arrow in the photo formed as the vehicle impacted the surface, kicking up regolith — the rock and dust that make up Moon “soil.” The faint bright halo encircling the site resulted from low-angle regolith particles scouring the delicate surface.
This animation shows the RESILIENCE site before and after the impact. In the image, north is up. Looking from west to east, or left to right, the area pictured covers 2 miles.Credit: NASA/Goddard/Arizona State University. LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington. Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon. NASA is returning to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.
