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.”

Video: 00:03:30 Two meteorological missions – Meteosat Third Generation Sounder-1 (MTG-S1) and the Copernicus Sentinel-4 mission – have launched on board a SpaceX Falcon 9 from Cape Canaveral in Florida, US.
Both are world-class Earth observation missions developed with European partners to address scientific and societal challenges.
The MTG-S1 satellite will generate a completely new type of data product, especially suited to nowcasting severe weather events, with three-dimensional views of the atmosphere. It is the second in the MTG constellation to be prepared for orbit and is equipped with the first European operational Infrared Sounder instrument.
Copernicus Sentinel-4 will be the first mission to monitor European air quality from geostationary orbit, providing hourly information that will transform how we predict air pollution across Europe, using its ultraviolet, visible, near-infrared light (UVN) spectrometer.

Asteroid 2024 YR4 made headlines earlier this year when its probability of impacting Earth in 2032 rose as high as 3%. While an Earth impact has now been ruled out, the asteroid’s story continues.
The final glimpse of the asteroid as it faded out of view of humankind’s most powerful telescopes left it with a 4% chance of colliding with the Moon on 22 December 2032.
The likelihood of a lunar impact will now remain stable until the asteroid returns to view in mid-2028. In this FAQ, find out why we are left with this lingering uncertainty and how ESA's planned NEOMIR space telescope will help us avoid similar situations in the future.
