Students from Eau Gallie High School in Melbourne, Florida, visited the Prototype Development Laboratory at NASA’s Kennedy Space Center in Florida on Monday, April 28, 2025. The science, technology, engineering, and mathematics (STEM) participants are interested in technical trades and had the chance to hear from technicians at the Prototype Development Laboratory who design, fabricate, and evaluate protypes, test articles, and test support equipment.
NASA Kennedy’s Office of STEM Engagement provides opportunities to attract, engage, and enable students seeking careers in science, technology, engineering, and mathematics.
“My technical training in high school plays a huge role in the work I do every day in the Prototype Laboratory,” said Spencer Wells, mechanical engineering technician at Prototype Development Laboratory. “If it weren’t for that training, I’m convinced I wouldn’t be here at NASA.”
Some of the participants also have worked on a project to design and build a wheel for a lunar excavator demonstration mission as part of the NASA HUNCH program, an instructional partnership between NASA and educational institutions.

Editor’s Note: The following is one of three related articles about the NASA Data Acquisition System and related efforts. Please visit Stennis News – NASA to access accompanying articles.
A blended team of NASA personnel and contractors support ongoing development and operation of the NASA Data Acquisition System at NASA’s Stennis Space Center. Team members include, left to right: Andrew Graves (NASA), Shane Cravens (Syncom Space Services), Peggi Marshall (Syncom Space Services), Nicholas Payton Karno (Syncom Space Services), Alex Elliot (NASA), Kris Mobbs (NASA), Brandon Carver (NASA), Richard Smith (Syncom Space Services), and David Carver (NASA)NASA/Danny Nowlin Members of the NASA Data Acquisition System team at NASA’s Stennis Space Center evaluate system hardware for use in monitoring and collecting propulsion test data at the site.NASA/Danny Nowlin NASA software engineer Alex Elliot, right, and Syncom Space Services software engineer Peggi Marshall fine-tune data acquisition equipment at NASA’s Stennis Space Center by adjusting an oscilloscope to capture precise measurements.

NASA/Danny Nowlin Just as a steady heartbeat is critical to staying alive, propulsion test data is vital to ensure engines and systems perform flawlessly.
The accuracy of the data produced during hot fire tests at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, tells the performance story.
So, when NASA needed a standardized way to collect hot fire data across test facilities, an onsite team created an adaptable software tool to do it.
“The NASA Data Acquisition System (NDAS) developed at NASA Stennis is a forward-thinking solution,” said David Carver, acting chief of the Office of Test Data and Information Management. “It has unified NASA’s rocket propulsion testing under an adaptable software suite to meet needs with room for future expansion, both within NASA and potentially beyond.”
Before NDAS, contractors conducting test projects used various proprietary tools to gather performance data, which made cross-collaboration difficult. NDAS takes a one-size-fits-all approach, providing NASA with its own system to ensure consistency.
“Test teams in the past had to develop their own software tools, but now, they can focus on propulsion testing while the NDAS team focuses on developing the software that collects data,” said Carver.
A more efficient workflow has followed since the software system is designed to work with any test hardware. It allows engineers to seamlessly work between test areas, even when upgrades have been made and hardware has changed, to support hot fire requirements for the agency and commercial customers.
With the backing and resources of the NASA Rocket Propulsion Test (RPT) Program Office, a blended team of NASA personnel and contractors began developing NDAS in 2011 as part of the agency’s move to resume control of test operations at NASA Stennis. Commercial entities had conducted the operations on NASA’s behalf for several decades.
The NASA Stennis team wrote the NDAS software code with modular components that function independently and can be updated to meet the needs of each test facility. The team used LabVIEW, a graphical platform that allows developers to build software visually rather than using traditional text-based code.

Making the program modular made it adaptable.”
During propulsion tests, the NDAS system captures both high-speed and low-speed sensor data. The raw sensor data is converted into units for both real-time monitoring and post-test analysis.
During non-test operations, the system monitors the facility and test article systems to help ensure the general health and safety of the facility and personnel.
“Having quality software for instrumentation and data recording systems is critical and, in recent years, has become increasingly important,” said Tristan Mooney, NASA instrumentation engineer. “Long ago, the systems used less software, or even none at all. Amplifiers were configured with physical knobs, and data was recorded on tape or paper charts. Today, we use computers to configure, display, and store data for nearly everything.”
Developers demonstrated the new system on the A-2 Test Stand in 2014 for the J-2X engine test project.
From there, the team rolled it out on the Fred Haise Test Stand (formerly A-1), where it has been used for RS-25 engine testing since 2015. A year later, teams used NDAS on the Thad Cochran Test Stand (formerly B-2) in 2016 to support SLS (Space Launch System) Green Run testing for future Artemis missions.
One of the project goals for the system is to provide a common user experience to drive consistency across test complexes and centers.
Kris Mobbs, current NASA project manager for NDAS, said the system “really shined” during the core stage testing. “We ran 24-hour shifts, so we had people from across the test complex working on Green Run,” Mobbs said. “When the different shifts came to work, there was not a big transition needed. Using the software for troubleshooting, getting access to views, and seeing the measurements were very common activities, so the various teams did not have a lot of build-up time to support that test.”
Following success at the larger test stands, teams started using NDAS in the E Test Complex in 2017, first at the E-2 Test Stand, then on the E-1 and E-3 stands in 2020.
Growth of the project was “a little overwhelming,” Lacher recalled. The team maintained the software on active stands supporting tests, while also continuing to develop the software for other areas and their many unique requirements.
Each request for change had to be tracked, implemented into the code, tested in the lab, then deployed and validated on the test stands.
“This confluence of requirements tested my knowledge of every stand and its uniqueness,” said Lacher. “I had to understand the need, the effort to meet it, and then had to make decisions as to the priorities the team would work on first.”
Creation of the data system and its ongoing updates have transformed into opportunities for growth among the NASA Stennis teams working together.
“From a mechanical test operations perspective, NDAS has been a pretty easy system to learn,” said Derek Zacher, NASA test operations engineer. “The developers are responsive to the team’s ideas for improvement, and our experience has consistently improved with the changes that enable us to view our data in new ways.”
Originally designed to support the RPT office at NASA Stennis, the software is expanding beyond south Mississippi to other test centers, attracting interest from various NASA programs and projects, and garnering attention from government agencies that require reliable and scalable data acquisition. “It can be adopted nearly anywhere, such as aerospace and defense, research and development institutions and more places, where data acquisition systems are needed,” said Mobbs. “It is an ever-evolving solution.”

Editor’s Note: The following is one of three related articles about the NASA Data Acquisition System and related efforts. Please visit Stennis News – NASA to access accompanying articles.
The NASA Data Acquisition System, developed at NASA Stennis, is used in multiple test areas at NASA’s Marshall Space Flight Center in Huntsville, Alabama, including Test Facility 116. The facility consists of an open-steel test stand structure, primarily used for subscale testing, and three adjacent test bays designed for large-scale/full-scale testing. NASA/Marshall Space Flight Center Teams at NASA’s Langley Research Center in Hampton, Virginia conduct a test in the 8-Foot High-Temperature Tunnel. The NASA Data Acquisition System, developed at NASA Stennis, represents a potential solution for engineers seeking to standardize data systems at NASA Langley. NASA/Langley Research Center Teams at Test Stand 403, located at NASA’s White Sands Test Facility in Las Cruces, New Mexico, plan to use the NASA Data Acquisition System to support testing and development projects related to NASA’s Orion spacecraft.NASA/White Sands Test Facility A data-focused software tool created at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, continues to expand its capabilities and use across the agency.
Much like the software on a cell phone, the NASA Data Acquisition System (NDAS) software evolves with updates to meet user needs.
“It is not just because we are seeking new opportunities that we evolve,” said Kris Mobbs, NASA project manager for NDAS. “It is because the community of people using this software tell us about all the new, cool things happening and how they want to use the tool.”
Created as a standard method for collecting rocket propulsion test data, NDAS is proving to be a building block to acquire, display, and process various datasets. The flexibility of the software has supplied solutions for NASA’s work in New Mexico and Alabama and is being evaluated for data acquisition needs in Virginia.
When NASA’s White Sands Test Facility in Las Cruces, New Mexico, needed a new data acquisition system with a flexible design, the facility reached out to NASA Stennis since the center had demonstrated success with a similar challenge.
“A major benefit for the agency is having a software platform that is agency owned and developed,” said Josh Simmons, White Sands technical upgrades lead. “Stennis is leading the way and the way the system is written and documented, other programmers can jump in, and the way they have it designed, it can continue on and that is key.”
The NASA Stennis team updated its NDAS platform based on input from White Sands personnel to make it more adaptable and to increase data acquisition rates.
“They look to understand the requirements and to develop an application that is flexible to meet everybody’s requirements,” Simmons said. “They are always willing to improve it, to make it more applicable to a wider audience.”
NDAS will be the primary data acquisition and control systems to support testing and development projects related to NASA’s Orion spacecraft.
“I would like to standardize around it here at White Sands,” said Simmons. “I want to show the worth and versatility of NDAS, so people who need it make a choice to use it.”
Meanwhile at NASA’s Marshall Space Flight Center in Huntsville, Alabama, NDAS is used in multiple areas for small-scale, subscale, and full-scale testing.
Devin Rios Ogle is a contractor software engineer at NASA Marshall, responsible for integrating and upgrading the data acquisition system in the testing areas. The system is used to record data on test sequences to verify they happen as intended.
“The visualization of data is really nice compared to other software I have worked with,” said Rios Ogle. “It is easier to see what data you want to see when you want to see it. You select a measurement, and you can see it in graph form, or tabular form, or however you would like. It is visually appealing and very easy to find the stuff you need.”
Rios Ogle is familiar with the database behind the system and understands what the program is trying to do. He particularly noted the modular approach built into the system, which allows users to adapt the software as needed and is a feature others would find beneficial.
Marcus Jackson, a contractor instrumentation and control engineer at NASA Marshall, echoed Ogle’s assessment of NDAS, noting that it has allowed the center to condense multiple systems into a single package that meets the team’s unique needs.
“Ultimately, NDAS provides us with an excellent software package that is built specifically for the kind of work performed here and at other test stands across the United States,” said Jackson. “It is easy to install, manage, and scale up. It doesn’t break, but if you do find a bug or issue, the NDAS team is very quick to respond and help you find a solution.”
NDAS also represents a potential solution for engineers seeking to standardize data systems at NASA’s Langley Research Center in Hampton, Virginia, a use that could positively impact a mission’s ability to make data-informed decisions.
“We are investigating alternatives for standardization at all Langley facilities,” said Scott Simmons, NASA Langley data systems engineer. “Standardization has the potential for significant maintenance cost savings and efficiencies because of the sharing of the software. Having an instance of NDAS available for the dynamic data system at the 8-Foot High Temperature tunnel enables us to evaluate it as a potential solution for standardization at Langley.”
As the nation’s largest hypersonic blow-down test facility, the tunnel duplicates, as near as possible, flight conditions that would be encountered by hypersonic vehicles at up to Mach 6.5, or more than six times the speed of sound.
Even as its use grows, the NASA Stennis-led software project continues to gain momentum as it expands its capabilities and collaboration with users.
“The goal is to provide a software portfolio that supports a wide range of exciting NASA projects, involving lots of talented people that collaborate and innovate new software solutions far into the future,” Mobbs said. “This is a community of innovative, ambitious, and supportive engineers and scientists across all engineering disciplines that are dedicated to advancing NASA’s bold missions.”

Researchers with NASA’s Exploration Research and Technology programs conduct molten regolith electrolysis testing inside Swamp Works at NASA’s Kennedy Space Center in Florida on Thursday, Dec. 5, 2024.NASA/Kim Shiflett As NASA works to establish a long-term presence on the Moon, researchers have reached a breakthrough by extracting oxygen at a commercial scale from simulated lunar soil at Swamp Works at NASA’s Kennedy Space Center in Florida. The achievement moves NASA one step closer to its goal of utilizing resources on the Moon and beyond instead of relying only on supplies shipped from Earth.
NASA Kennedy researchers in the Exploration Research and Technology programs teamed up with Lunar Resources Inc. (LUNAR), a space industrial company in Houston, Texas, to perform molten regolith electrolysis. Researchers used the company’s resource extraction reactor, called LR-1, along with NASA Kennedy’s vacuum chamber. During the recent vacuum chamber testing, molecular oxygen was measured in its pure form along with the production of metals from a batch of dust and rock that simulates lunar soil, often referred to as “regolith,” in the industry.
“This is the first time NASA has produced molecular oxygen using this process,” said Dr. Annie Meier, molten regolith electrolysis project manager at NASA Kennedy. “The process of heating up the reactor is like using an elaborate cooking pot. Once the lid is on, we are essentially watching the gas products come out.”
During testing, the vacuum environment chamber replicated the vacuum pressure of the lunar surface. The extraction reactor heated about 55 pounds (25 kilograms) of simulated regolith up to a temperature of 3100°F (1700°C) until it melted. Researchers then passed an electric current through the molten regolith until oxygen in a gas form was separated from the metals of the soil. They measured and collected the molecular oxygen for further study.
In addition to air for breathing, astronauts could use oxygen from the Moon as a propellant for NASA’s lunar landers and for building essential infrastructure. This practice of in-situ resource utilization (ISRU) also decreases the costs of deep space exploration by reducing the number of resupply missions needed from Earth.
Once the process is perfected on Earth, the reactor and its subsystems can be delivered on future missions to the Moon. Lunar rovers, similar to NASA’s ISRU Pilot Excavator, could autonomously gather the regolith to bring back to the reactor system to separate the metals and oxygen.
“Using this unique chemical process can produce the oxidizer, which is half of the propellant mix, and it can create vital metals used in the production of solar panels that in turn could power entire lunar base stations,” said Evan Bell, mechanical structures and mechatronics lead at NASA Kennedy.
Post-test data analysis will help the NASA and LUNAR teams better understand the thermal and chemical function of full-scale molten regolith electrolysis reactors for the lunar surface. The vacuum chamber and reactor also can be upgraded to represent other locations of the lunar environment as well as conditions on Mars for further testing.
Researchers at NASA Kennedy began developing and testing molten regolith electrolysis reactors in the early 1990s. Swamp Works is a hands-on learning environment facility at NASA Kennedy that takes ideas through development and into application to benefit space exploration and everyone living on Earth. From 2019 to 2023, Swamp Works developed an early concept reactor under vacuum conditions named Gaseous Lunar Oxygen from Regolith Electrolysis (GaLORE). Scientists at NASA’s Johnson Space Center in Houston conducted similar testing in 2023, removing carbon monoxide from simulated lunar regolith in a vacuum chamber.
“We always say that Kennedy Space Center is Earth’s premier spaceport, and this breakthrough in molten regolith electrolysis is just another aspect of us being the pioneers in providing spaceport capabilities on the Moon, Mars, and beyond,” Bell said.
NASA’s Exploration Research and Technology programs, related laboratories, and research facilities develop technologies that will enable human deep space exploration. NASA’s Game Changing Development program, managed by the agency’s Space Technology Mission Directorate funded the project.
