Intuitive Machines' lunar terrain vehicle is white with a blue stripe on the front and their logo on the top of their rover. Lunar Outpost's lunar terrain vehicle is grey with green lights.
Through NASA’s Artemis campaign, astronauts will land on the lunar surface and use a new generation of spacesuits and rovers as they live, work, and conduct science in the Moon’s South Pole region, exploring more of the lunar surface than ever before. Recently, the agency completed the first round of testing on three commercially owned and developed LTVs (Lunar Terrain Vehicle) from Intuitive Machines, Lunar Outpost, and Venturi Astrolab at NASA’s Johnson Space Center in Houston.

Venturi Astrolab’s FLEX, Intuitive Machines’ Moon RACER, and Lunar Outpost’s Eagle lunar terrain vehicle – three commercially owned and developed LTVs (Lunar Terrain Vehicle) – are pictured at NASA’s Johnson Space Center in Houston in this photo from Nov. 21, 2024.

As part of an ongoing year-long feasibility study, each company delivered a static mockup of their vehicle to Johnson at the end of September, initiated rover testing in October and completed the first round of testing in December inside the Active Response Gravity Offload System (ARGOS) test facility. Lunar surface gravity is one-sixth of what we experience here on Earth, so to mimic this, ARGOS offers an analog environment that can offload pressurized suited subjects for various reduced gravity simulations.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      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 Syncom Space Services software test engineer Nicholas Payton Karno monitors a lab console at NASA’s Stennis Space Center displaying video footage of an RS-25 engine gimbal test, alongside data acquisition screens showing lab 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.

NASA/Danny Nowlin NASA engineers Steven Helmstetter, Christoffer Barnett-Woods, and Tristan Mooney perform checkouts on a large data acquisition system for the E-1 Test Stand at NASA’s Stennis Space Center. The data acquisition hardware, which supports testing for E Test Complex commercial customers, is controlled by NASA Data Acquisition System software that allows engineers to view real-time data while troubleshooting hardware configuration.NASA/Danny Nowlin NASA engineers Steven Helmstetter, left, and Tristan Mooney work with the NASA Data Acquisition System in the E-1 Test Control Center, where the system is utilized for propulsion test activities.NASA/Danny Nowlin “These were very good decisions by the original team looking toward the future,” said Joe Lacher, a previous NASA project manager. “LabVIEW was a new language and is now taught in colleges and widely used in industry. 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.”

      One half of NASA’s nearly complete Nancy Grace Roman Space Telescope just passed a lengthy test to ensure it will function properly in the space environment. This milestone keeps Roman well on track for its target launch by May 2027, with the team aiming for as early as fall 2026.
      This photo shows half of the NASA’s Nancy Grace Roman observatory — the outer barrel assembly, deployable aperture cover, and test solar arrays — fully deployed in a thermal chamber at NASA’s Goddard Space Flight Center in Greenbelt, Md., for environmental testing. Credit: NASA/Sydney Rohde “This milestone tees us up to attach the flight solar array sun shield to the outer barrel assembly, and deployable aperture cover, which we’ll begin this month,” said Jack Marshall, who leads integration and testing for these elements at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Then we’ll complete remaining environmental tests for the flight assembly before moving on to connect Roman’s two major assemblies and run the full observatory through testing, and then we’ll be ready to launch!”
      Prior to this thermal testing, technicians integrated Roman’s deployable aperture cover, a visor-like sunshade, to the outer barrel assembly, which will house the telescope and instruments, in January, then added test solar panels in March. They moved this whole structure into the Space Environment Simulator test chamber at NASA Goddard in April.
      There, it was subjected to the hot and cold temperatures it will experience in space. Next, technicians will join Roman’s flight solar panels to the outer barrel assembly and sunshade. Then the structure will undergo a suite of assessments, including a shake test to ensure it can withstand the vibrations experienced during launch.
      This photo captures the installation of the test solar panels for NASA’s Nancy Grace Roman Space Telescope, which took place in March. One panel is lifted in the center of the frame on its way to being attached to the outer barrel assembly at right. The deployable aperture cover is stowed on the front of the outer barrel assembly, and the other half of the observatory — the spacecraft and integrated payload assembly, which consists of the telescope, instrument carrier, and two instruments — appears at the left of the photo.Credit: NASA/Jolearra Tshiteya Meanwhile, Roman’s other major portion — the spacecraft and integrated payload assembly, which consists of the telescope, instrument carrier, and two instruments — will undergo its own shake test, along with additional assessments. Technicians will install the lower instrument sun shade and put this half of the observatory through a thermal vacuum test in the Space Environment Simulator.
      “The test verifies the instruments will remain at stable operating temperatures even while the Sun bakes one side of the observatory and the other is exposed to freezing conditions — all in a vacuum, where heat doesn’t flow as readily as it does through air,” said Jeremy Perkins, an astrophysicist serving as Roman’s observatory integration and test scientist at NASA Goddard. Keeping the instrument temperatures stable ensures their readings will be precise and reliable.
      Technicians are on track to connect Roman’s two major parts in November, resulting in a complete observatory by the end of the year. Following final tests, Roman is expected to ship to the launch site at NASA’s Kennedy Space Center in Florida for launch preparations in summer 2026. Roman remains on schedule for launch by May 2027, with the team aiming for launch as early as fall 2026.

      Technicians move the Orion spacecraft for NASA’s Artemis II test flight out of the Neil A. Armstrong Operations and Checkout Building to the Multi-Payload Processing Facility at Kennedy Space Center in Florida on Saturday, May 3, 2025. NASA/Kim Shiflett Engineers, technicians, mission planners, and the four astronauts set to fly around the Moon next year on Artemis II, NASA’s first crewed Artemis mission, are rapidly progressing toward launch.

      At the agency’s Kennedy Space Center in Florida, teams are working around the clock to move into integration and final testing of all SLS (Space Launch System) and Orion spacecraft elements. Recently they completed two key milestones – connecting the SLS upper stage with the rest of the assembled rocket and moving Orion from its assembly facility to be fueled for flight.

      “We’re extremely focused on preparing for Artemis II, and the mission is nearly here,” said Lakiesha Hawkins, assistant deputy associate administrator for NASA’s Moon to Mars Program, who also will chair the mission management team during Artemis II. “This crewed test flight, which will send four humans around the Moon, will inform our future missions to the Moon and Mars.”
      Teams with NASA’s Exploration Ground Systems Program begin integrating the interim cryogenic propulsion stage to the SLS (Space Launch System) launch vehicle stage adapter on Wednesday, April 30, 2025, inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. NASA/Isaac Watson On May 1, technicians successfully attached the interim cryogenic propulsion stage to the SLS rocket elements already poised atop mobile launcher 1, including its twin solid rocket boosters and core stage, inside the spaceport’s Vehicle Assembly Building (VAB). This portion of the rocket produces 24,750 pounds of thrust for Orion after the rest of the rocket has completed its job. Teams soon will move into a series of integrated tests to ensure all the rocket’s elements are communicating with each other and the Launch Control Center as expected. The tests include verifying interfaces and ensuring SLS systems work properly with the ground systems.

      Meanwhile, on May 3, Orion left its metaphorical nest, the Neil Armstrong Operations & Checkout Facility at Kennedy, where it was assembled and underwent initial testing. There the crew module was outfitted with thousands of parts including critical life support systems for flight and integrated with the service module and crew module adapter. Its next stop on the road to the launch pad is the Multi-Payload Processing Facility, where it will be carefully fueled with propellants, high pressure gases, coolant, and other fluids the spacecraft and its crew need to maneuver in space and carry out the mission.

      After fueling is complete, the four astronauts flying on the mission around the Moon and back over the course of approximately 10 days, will board the spacecraft in their Orion Crew Survival System spacesuits to test all the equipment interfaces they will need to operate during the mission. This will mark the first time NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen, will board their actual spacecraft while wearing their spacesuits. After the crewed testing is complete, technicians will move Orion to Kennedy’s Launch Abort System Facility, where the critical escape system will be added. From there, Orion will move to the VAB to be integrated with the fully assembled rocket.

      NASA also announced its second agreement with an international space agency to fly a CubeSat on the mission. The collaborations provide opportunities for other countries to work alongside NASA to integrate and fly technology and experiments as part of the agency’s Artemis campaign.

      While engineers at Kennedy integrate and test hardware with their eyes on final preparations for the mission, teams responsible for launching and flying the mission have been busy preparing for a variety of scenarios they could face.

      The launch team at Kennedy has completed more than 30 simulations across cryogenic propellant loading and terminal countdown scenarios. The crew has been taking part in simulations for mission scenarios, including with teams in mission control. In April, the crew and the flight control team at NASA’s Johnson Space Center in Houston simulated liftoff through a planned manual piloting test together for the first time. The crew also recently conducted long-duration fit checks for their spacesuits and seats, practicing several operations while under various suit pressures.
      NASA astronaut Christina Koch participates in a fit check April 18, 2025, in the spacesuit she will wear during Artemis II. NASA/Josh Valcarcel Teams are heading into a busy summer of mission preparations. While hardware checkouts and integration continue, in coming months the crew, flight controllers, and launch controllers will begin practicing their roles in the mission together as part of integrated simulations. In May, the crew will begin participating pre-launch operations and training for emergency scenarios during launch operations at Kennedy and observe a simulation by the launch control team of the terminal countdown portion of launch. In June, recovery teams will rehearse procedures they would use in the case of a pad or ascent abort off the coast of Florida, with launch and flight control teams supporting. The mission management team, responsible for reviewing mission status and risk assessments for issues that arise and making decisions about them, also will begin practicing their roles in simulations. Later this summer, the Orion stage adapter will arrive at the VAB from NASA’s Marshall Spaceflight Center in Huntsville, Alabama, and stacked on top of the rocket.

      NASA astronauts Reid Wiseman (foreground) and Victor Glover participate in a simulation of their Artemis II entry profile on March 13, 2025.NASA/Bill Stafford Through Artemis, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

      4 Min Read NASA Expands SPHEREx Science Return Through Commercial Partnership
      A sectional rendering of NASA's SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer). Credits: NASA NASA is partnering with commercial industry to expand our knowledge of Earth, our solar system, and beyond. Recently, NASA collaborated with Kongsberg Satellite Services (KSAT) to support data transfer for the agency’s SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer) mission to explore the origins of the universe. 
      “Not only is NASA moving toward commercialization, the agency is making technological advancements to existing systems and saving millions of dollars in the process — all while expanding human knowledge through science and exploration missions,” said Kevin Coggins, associate administrator for NASA’s SCaN (Space Communications and Navigation) program.
      To receive data from missions in space, NASA relies on the Near Space Network and Deep Space Network, a collection of antennas around the globe.
      In preparation for the recently-launched SPHEREx observatory, NASA needed to upgrade an antenna on the world’s most remote continent: Antarctica.
      Transmitted via NASA’s Near Space Network, this video shows SPHEREx scanning a region of the Large Magellanic Cloud. The shifting colors represent different infrared wavelengths detected by the telescope’s two arrays. Credit: NASA/JPL-Caltech NASA’s SCaN program took a novel approach by leveraging its established commercial partnership with KSAT. While upgraded KSAT antennas were added to the Near Space Network in 2023, SPHEREx required an additional Antarctic antenna that could link to online data storage.
      To support SPHEREx’s polar orbit, KSAT upgraded its Troll, Antarctica antenna and incorporated their own cloud storage system. NASA then connected KSAT’s cloud to the NASA cloud, DAPHNE+ (Data Acquisition Process and Handling Environment).
      As the Near Space Network’s operational cloud services system, DAPHNE+ enables science missions to transmit their data to the network for virtual file storage, processing, and management. 
      “By connecting the Troll antenna to DAPHNE+, we eliminated the need for large, undersea fiberoptic cables by virtually connecting private and government-owned cloud systems, reducing the project’s cost and complexity,” said Matt Vincent, the SPHEREx mission manager for the Near Space Network at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
      Each day, SPHEREx downlinks a portion of its 20 gigabits of science data through the Troll antenna, which transfers the files across KSAT’s network of relay satellites to the DAPHNE+ cloud. The cloud system combines and centralizes the data from each antenna, allowing access to all of SPHEREx’s health and science data in one convenient place. 
      The SPHEREx mission data is transmitted from space to the Troll Satellite Station, relayed through a network of satellites, and stored in the Near Space Network’s cloud system for easily-accessible analysis by scientists around the world.NASA/Dave Ryan With coverage throughout its orbit, SPHEREx transmits its 3D maps of the celestial sky, offering new insight into what happened a fraction of a second after the big bang. 
      “Missions like SPHEREx use the Near Space Network’s combination of commercial and government antennas,” explained Michael Skube, DAPHNE+ manager at NASA Goddard. “And that is the benefit of DAPHNE+ — it enables the network to pull different sources of information into one central location. The DAPHNE+ system treats government and commercial antennas as part of the same network.” 
      The partnership is mutually beneficial. NASA’s Near Space Network maintains a data connection with SPHEREx as it traverses both poles and KSAT benefits from its antennas’ integration into a robust global network – no new cables required. 
       “We were able to find a networking solution with KSAT that did not require us to put additional hardware in Antarctica,” said Vincent. “Now we are operating with the highest data rate we have ever downlinked from that location.” 
      The upgraded ground station antenna at Troll Satellite Station supports cloud-based space communications, enabling NASA’s Near Space Network to support scientific missions via a wireless cloud network.Kongsberg Satellite Services For NASA, its commercial partners, and other global space agencies, this expansion means more reliable space communications with fewer expenses. 
      Troll’s successful integration into the Near Space Network is a case study for future private and government partnerships. As SPHEREx measures the collective glow of over 450 million galaxies as far as 10 billion light-years away, SCaN continues to innovate how its discoveries safely return to Earth. 
      The SPHEREx mission is managed by NASA’s Jet Propulsion Laboratory in Southern California for the agency’s Astrophysics Division within the Science Mission Directorate at NASA Headquarters. Data will be processed and archived at IPAC at Caltech. The SPHEREx dataset will be publicly available at the NASA-IPAC Infrared Science Archive. Funding and oversight for DAPHNE+ and the Near Space Network come from the SCaN program office at NASA Headquarters and operate out of NASA’s Goddard Space Flight Center. The Troll Satellite Station is owned and operated by Kongsberg Satellite Services and located in Queen Maud Land, Antarctica.

      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.
