Creating a golden streak in the night sky, a SpaceX Falcon 9 rocket carrying Intuitive Machines’ Nova-C lunar lander (IM-2) and NASA’s Lunar Trailblazer soars upward after liftoff from Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 7:16 p.m. EST, Wednesday, Feb. 26. The IM-2 launch, which is part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, is carrying NASA technology and science demonstrations, and other commercial payloads to Mons Mouton, a lunar plateau to advance our understanding of the Moon and planetary processes, while paving the way for future crewed missions. (Credit: NASA) The next set of NASA science and technology demonstrations is on its way to the lunar surface, where they will gather data about Earth’s nearest neighbor and help pave the way for American astronauts to explore the Moon and beyond, for the benefit of all.
Carrying NASA instruments as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign, Intuitive Machines’ IM-2 mission launched at 7:16 p.m. EST, Feb. 26, aboard a SpaceX Falcon 9 rocket from Launch Complex 39A at the agency’s Kennedy Space Center in Florida. Intuitive Machines’ lunar lander is scheduled to touch down on Thursday, March 6, in Mons Mouton, a plateau in the Moon’s South Pole.
“With each CLPS mission, the United States is leading the way in expanding our reach and refining our capabilities, turning what was once dreams into reality,” said NASA acting Administrator Janet Petro. “These science and technology demonstrations are more than payloads – they represent the foundation for future explorers who will live and work on the Moon. By partnering with American industry, we are driving innovation, strengthening our leadership in space, and preparing for sending humans farther into the solar system, including Mars.”
Intuitive Machines’ NOVA-C lunar lander captures a selfie with Earth in the background shortly after separation. Credit: Intuitive Machines Once on the Moon, the NASA CLPS investigations will aim to measure the potential presence of volatiles or gases from lunar soil – one of the first on-site demonstrations of resource use on the Moon. In addition, a passive Laser Retroreflector Array on the top deck of the lander will bounce laser light back at any future orbiting or incoming spacecraft to give them a permanent reference point on the lunar surface. Other technology instruments on this delivery will demonstrate a robust surface communications system and deploy a propulsive drone designed to hop across the lunar surface.
NASA’s Lunar Trailblazer spacecraft, which launched as a rideshare with the IM-2 mission, also began its journey to lunar orbit, where it will map the distribution of the different forms of water on the Moon. Lunar Trailblazer will discover where the Moon’s water is, what form it is in, and how it changes over time. Observations gathered during its two-year prime mission will contribute to the understanding of water cycles on airless bodies throughout the solar system while also supporting future human and robotic missions to the Moon by identifying where water is located.
NASA’s Artemis campaign includes conducting more science to better understand planetary processes and evolution, to search for evidence of water and other resources, and support long-term, sustainable human exploration.
The NASA science and technology instruments that launched aboard the IM-2 mission are:
Polar Resources Ice Mining Experiment-1 (PRIME-1): This experiment will explore the Moon’s subsurface and analyze where lunar resources may reside. The experiment’s two key instruments will demonstrate the ability to extract and analyze lunar soil to detect volatile chemical compounds that turn into gas. The two instruments will work in tandem: The Regolith and Ice Drill for Exploring New Terrains will drill into the Moon’s surface to collect samples, while the Mass Spectrometer Observing Lunar Operations will analyze these samples to determine the gas composition released across the sampling depth. The PRIME-1 technology will provide valuable data to better understand the Moon’s surface and how to work with and on it. Laser Retroreflector Array (LRA): This collection of eight retroreflectors will enable precision laser ranging, which is a measurement of the distance between the orbiting or landing spacecraft to the reflector on the lander. The LRA is a passive optical instrument and will function as a permanent location marker on the Moon for decades to come. Micro Nova Hopper: Funded by NASA’s Space Technology Mission Directorate Tipping Point initiative, Intuitive Machines’ Micro Nova hopper, Grace, is designed to enable high-resolution surveying of the lunar surface under its flight path. This autonomous propulsive drone aims to deploy to the surface and hop into a nearby crater to survey the lunar surface and send science data back to the lander. It’s designed to hop in and out of a permanently shadowed region, providing a first look into undiscovered regions that may provide critical information to sustain a human presence on the Moon. Nokia Lunar Surface Communications System (LSCS): Also developed with funding from NASA’s Tipping Point initiative, Nokia’s LSCS 4G/LTE communications system will demonstrate cellular communications between the Intuitive Machines lander, a Lunar Outpost rover, and the Micro Nova hopper. Engineered to transmit high-definition video, command-and-control messages, and sensor and telemetry data, the LSCS aims to demonstrate an ultra-compact advanced communication solution for future infrastructure on the Moon and beyond.

Portrait of John Boyd, whose contributions to NASA spanned more than 70 years.Credit: NASA John Boyd, known to many as Jack and whose career spanned more than seven decades in a multitude of roles across NASA as well as its predecessor, the National Advisory Committee for Aeronautics (NACA), died Feb. 20. He was 99. Born in 1925, and raised in Danville, Virginia, he was a long-time resident of Saratoga, California.
Boyd is being remembered by many across the agency, including Dr. Eugene Tu, director, NASA’s Ames Research Center in California’s Silicon Valley, where Boyd spent most of his career.
“Jack brought an energy, optimism, and team-based approach to solving some of the greatest technological challenges humanity has ever faced, which remains part of our culture to this day,” said Tu. “There are few careers as wide-ranging and impactful as Jack’s.”
In 1947, Boyd began his career at the then-called Ames Aeronautical Laboratory in Moffett Field, California, as an aeronautical engineer working to design and test various wing shapes using the center’s 1-by-3-foot supersonic wind tunnel. Boyd continued conducting research in wind tunnels, testing designs that led to dramatic increases in the efficiency of the supersonic B-58 bomber, as well as the F-102 and F-106 fighters.
In 1958, just before Ames became part of a newly established NASA, Boyd recalled thinking, “Maybe someday we’ll go out into the far blue yonder, and if we do, what are we going to fly? How are we going to bring it back into the atmosphere safely?” He and a team of engineers turned their attention to studying the dynamics of high-speed projectiles in hypervelocity ranges, filled with different mixtures of gases to mimic the atmospheres of Mars and Venus, in preparation for sending spacecraft out into space and safely back again or to the surface of other worlds.
By the mid-60s, Boyd was promoted into leadership and tapped to become deputy director for Aeronautics and Flight Systems at NASA Ames. In the late 1960s, as America was redefining its space exploration goals and sending humans to the Moon, Boyd served as the center’s lead to assist NASA Headquarters in Washington consolidate and create new research programs.
In 1979, Boyd served as the deputy director at NASA’s Dryden Flight Research Center (now known as NASA’s Armstrong Flight Research Center) in Edwards, California, and prepared the center for its role as a landing site for the space shuttle. He briefly returned to Ames before heading to NASA Headquarters to be associate administrator for management under James M. Beggs. Boyd left government service in 1985, taking a position as chancellor for research and an adjunct professor of aerodynamics, engineering, and the history of spaceflight for the University of Texas System.
Boyd returned to NASA and California’s Silicon Valley in 1993,inspiring students through educational outreach initiatives, and serving as the senior advisor to the director, senior advisor for history, and the center ombudsman until his retirement in 2020.
Boyd credits his interest in airplanes to a cousin who was a paratrooper and gave him a ride in a biplane in the 1940s. In 1943, he enrolled and became the first in his family to earn a degree with a bachelor of science in aeronautical engineering from Virginia Polytechnic Institute and State University in Blacksburg, Virginia. He was a recipient of the NASA Exceptional Service Award, the NASA Outstanding Leadership Award, the NASA Equal Employment Opportunity Medal, the Presidential Rank of Meritorious Executive, the NASA Distinguished Service Medal, the Army Command Medal, and the NASA Headquarters History Award. He also was a Fellow of the American Institute of Aeronautics and Astronautics and a Sloan Fellow at Stanford University.
“The agency and the nation thank and honor Jack as a member of the NASA family and the highest exemplar of a public servant who believed investing in others is the greatest contribution one can make,” added Tu. “He will be deeply missed.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Sunlight gleams off NASA’s Lunar Trailblazer as the dishwasher-size spacecraft orbits the Moon in this artist’s concept. The mission will discover where the Moon’s water is, what form it is in, and how it changes over time, producing the best-yet maps of water on the lunar surface.Lockheed Martin Space The small satellite mission will map the Moon to help scientists better understand where its water is, what form it’s in, how much is there, and how it changes over time.
Launching no earlier than Wednesday, Feb. 26, NASA’s Lunar Trailblazer will help resolve an enduring mystery: Where is the Moon’s water? After sharing a ride on a SpaceX Falcon 9 rocket with Intuitive Machines’ IM-2 launch — part of NASA’s CLPS (Commercial Lunar Payload Services) initiative — the small satellite will take several months to arrive in lunar orbit.
Here are six things to know about the mission.
1. Lunar Trailblazer will produce high-resolution maps of water on the lunar surface.
One of the biggest lunar discoveries in recent decades is that the Moon’s surface has quantities of water, but little about its nature is known. To investigate, Lunar Trailblazer will decipher where the water is, what form it is in, how much is there, and how it changes over time. The small satellite will produce the best-yet maps of water on the lunar surface. Observations gathered during the two-year prime mission will also contribute to the understanding of water cycles on airless bodies throughout the solar system.
2. The small satellite will use two state-of-the-art science instruments.
Key to achieving these goals are the spacecraft’s two science instruments: the High-resolution Volatiles and Minerals Moon Mapper (HVM3) infrared spectrometer and the Lunar Thermal Mapper (LTM) infrared multispectral imager. NASA’s Jet Propulsion Laboratory in Southern California provided the HVM3 instrument, while LTM was built by the University of Oxford and funded by the UK Space Agency.
HVM3 will detect and map the spectral fingerprints, or wavelengths of reflected sunlight, of minerals and the different forms of water on the lunar surface. The LTM instrument will map the minerals and thermal properties of the same landscape. Together they will create a picture of the abundance, location, and form of water while also tracking how its distribution changes over time and temperature.
Fueled and attached to an adaptor used for secondary payloads, NASA’s Lunar Trailblazer is seen at SpaceX’s payload processing facility within NASA’s Kennedy Space Center in Florida in early February 2025. The small satellite is riding along on Intuitive Machines’ IM-2 launch.SpaceX 3. Lunar Trailblazer will take a long and winding road to the Moon.
Weighing only 440 pounds (200 kilograms) and measuring 11.5 feet (3.5 meters) wide with its solar panels fully deployed, Lunar Trailblazer is about the size of a dishwasher and relies on a relatively small propulsion system. To make the spacecraft’s four-to-seven-month trip to the Moon (depending on the launch date) as efficient as possible, the mission’s design and navigation team has planned a looping trajectory that will use the gravity of the Sun, Earth, and Moon to guide Lunar Trailblazer to its final science orbit — a technique called low-energy transfer.
4. The spacecraft will peer into the darkest parts of the Moon’s South Pole.
Lunar Trailblazer’s science orbit positions it to peer into the craters at the Moon’s South Pole using the HVM3 instrument. What makes these craters so intriguing is that they harbor cold traps that may not have seen direct sunlight for billions of years, which means they’re a potential hideout for frozen water. The HVM3 spectrometer is designed to use faint reflected light from the walls of craters to see the floor of even permanently shadowed regions. If Lunar Trailblazer finds significant quantities of ice at the base of the craters, those locations could be pinpointed as a resource for future lunar explorers.
5. Lunar Trailblazer is a high-risk, low-cost mission.
Lunar Trailblazer was a 2019 selection of NASA’s SIMPLEx (Small Innovative Missions for Planetary Exploration), which provides opportunities for low-cost science spacecraft to ride-share with selected primary missions. To maintain a lower overall cost, SIMPLEx missions have a higher risk posture and lighter requirements for oversight and management. This higher risk acceptance allows NASA to enable science missions that could not otherwise be done.
6. Future missions will benefit from Lunar Trailblazer’s data.
Mapping the Moon’s water supports future human and robotic lunar missions. With knowledge from Lunar Trailblazer of where water is located, astronauts could process lunar ice to create water for human use, breathable oxygen, or fuel. And they could conduct science by sampling the ice for later study to determine the water’s origins.
More About Lunar Trailblazer
Lunar Trailblazer is led by Principal Investigator Bethany Ehlmann of Caltech in Pasadena, California. Caltech also leads the mission’s science investigation, and Caltech’s IPAC leads mission operations, which includes planning, scheduling, and sequencing of all spacecraft activities. NASA JPL manages Lunar Trailblazer and provides system engineering, mission assurance, the HVM3 instrument, and mission design and navigation. JPL is managed by Caltech for NASA. Lockheed Martin Space provided the spacecraft, integrated the flight system, and supports operations under contract with Caltech. The University of Oxford developed and provided the LTM instrument, funded by the UK Space Agency. Lunar Trailblazer, part of NASA’s Lunar Discovery Exploration Program, is managed by NASA’s Planetary Mission Program Office at Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Science Mission Directorate in Washington.

6 Min Read NASA Stennis Flashback: Learning About Rocket Engine Smoke for Safe Space Travel
An image shows engineers at an early version of the test stand at the Diagnostic Testbed Facility. From 1988 to the mid-1990s, NASA Stennis engineers operated the facility to conduct rocket engine plume exhaust diagnostics and learn more about the space shuttle main engine combustion process. Credits: NASA/Stennis NASA’s Stennis Space Center near Bay St. Louis, Mississippi, is widely known as the nation’s largest rocket propulsion test site. More than 35 years ago, it also served as a hands-on classroom for NASA engineers seeking to improve the efficiency of space shuttle main engines.
From 1988 to the mid-1990’s, NASA Stennis engineers operated a Diagnostic Test Facility to conduct rocket engine plume exhaust diagnostics and learn more about the space shuttle main engine combustion process. The effort also laid the groundwork for the frontline research-and-development testing conducted at the center today.
“The Diagnostic Test Facility work is just another example of the can-do, will-do attitude of the NASA Stennis team and of its willingness to support the nation’s space exploration program in all ways needed and possible,” said Joe Schuyler, director of the NASA Stennis Engineering and Test Directorate.

Tests conducted at the Diagnostic Testbed Facility played a critical safety role for engine operations and also provided a real-time opportunity for NASA Stennis engineers to learn about exhaust diagnostics. NASA/Stennis An image shows the Diagnostic Testbed Facility test stand data acquisition trailer. NASA/Stennis The Need
Envision a rocket or space vehicle launching into the sky. A trail of bright exhaust, known as the engine plume, follows. As metals wear down in the engines from the intense heat of the combustion process, the flame glows with colors, some visible, such as orange or yellow, and others undetectable by the human eye.
The colors tell a story – about the health and operation of the engine and its components. For space shuttle main engines, which flew on multiple missions, engineers needed to understand that story, much as a doctor needs to understand the condition of a human body during checkup, to ensure future engine operation.
Where better place to study such details than the nation’s premier propulsion test site? Paging NASA Stennis.

NASA Stennis has long enabled and supported innovative and collaborative work to benefit both the agency and the commercial space industry. When NASA came calling in the late 1980s, site engineers went to work on a plan to study space shuttle main engine rocket exhaust.
The concept for an enabling structure about the size of a home garage was born in October 1987. Five months later, construction began on a Diagnostic Testbed Facility to provide quality research capabilities for studying rocket engine exhaust and learning more about the metals burned off during hot fire.
The completed facility featured a 1,300-square-foot control and data analysis center, as well as a rooftop observation deck. Small-scale infrastructure was located nearby for testing a 1,000-pound-thrust rocket engine that simulated the larger space shuttle main engine. The 1K engine measured about 2 feet in length and six inches in diameter. Using a small-scale engine allowed for greater flexibility and involved less cost than testing the much-larger space shuttle engine.
An image shows Sverdrup Technology’s Robert Norfleet as he preps the dopant injection system for testing at the Diagnostic Testbed Facility. The goal of the facility was to inject known metals and materials in a chemical form and then look at what emissions were given off. During one test, generally a six or 12 second test, operators would inject three known dopants, or substances, and then run distilled water between each test to clean out the system.NASA/Stennis An image shows engineers Stan Gill, Robert Norfleet, and Elizabeth Valenti in the Diagnostic Testbed Facility test control center. NASA/Stennis The Process
Engineers could quickly conduct multiple short-duration hot fires using the smaller engine. A six-second test provided ample time to collect data from engine exhaust that reached as high as 3,900 degrees Fahrenheit.
Chemical solutions simulating engine materials were injected into the engine combustion chamber for each hot fire. The exhaust plume then was analyzed using a remote camera, spectrometer, and microcomputers to determine what colors certain metals and elements emit when burning.
Each material produced a unique profile. By matching the profiles to the exhaust of space shuttle main engine tests conducted at NASA Stennis, determinations could be made about which engine components were undergoing wear and what maintenance was needed.
We learned about purging, ignition, handling propellants, high-pressure gases, and all the components you had to have to make it work…It was a very good learning experience.
Glenn Varner
NASA Stennis Engineer
The Benefits
The Diagnostic Testbed Facility played a critical safety role for engine operations and also provided a real-time opportunity for NASA Stennis engineers to learn about exhaust diagnostics.
Multiple tests were conducted. The average turnaround time between hot fires was 18 to 20 minutes with the best turnaround from one test to another taking just 12 minutes. By January 1991, the facility had recorded a total of 588 firings for a cumulative 3,452 seconds.
As testing progressed, the facility team evolved into a collection of experts in plume diagnostics. Longtime NASA Stennis engineer Glenn Varner serves as the mechanical operations engineer at the Thad Cochran Test Stand, where he contributed to the successful testing of the first SLS (Space Launch System) core stage onsite.
However, much of Varner’s hands-on experience came at the Diagnostic Test Facility. “We learned about purging, ignition, handling propellants, high-pressure gases, and all the components you had to have to make it work,” he said. “It was a very good learning experience.”

The Impact
The Diagnostic Testbed Facility impacted more than just those engineers involved in the testing. Following the initial research effort, the facility underwent modifications in January 1993. Two months later, facility operators completed a successful series of tests on a small-scale liquid hydrogen turbopump for a California-based aerospace company.
The project marked an early collaboration between the center and a commercial company and helped pave the way for the continued success of the NASA Stennis E Test Complex. Building on Diagnostic Testbed Facility knowledge and equipment, the NASA Stennis complex now supports multiple commercial aerospace projects with its versatile infrastructure and team of propulsion test experts.
“The physical remnants of the Diagnostic Testbed Facility are barely recognizable now,” Schuyler said. “But that spirit and approach embodied by that effort and its teams continues in force at the center.”
Additional Information
NASA Stennis has leveraged hardware and expertise from the Diagnostic Testbed Facility to provide benefit to NASA and industry for two decades and counting.
The facility’s thruster, run tanks, valves, regulators and instrumentation were used in developing the versatile four-stand E Test Complex at NASA Stennis that includes 12 active test cell positions capable of various component, engine, and stage test activities.
“The Diagnostic Testbed Facility was the precursor to that,” said NASA engineer Glenn Varner. “Everything but the structure still in the grass moved to the E-1 Test Stand, Cell 3. Plume diagnostics was part of the first testing there.”
When plume diagnostic testing concluded at E-1, equipment moved to the E-3 Test Stand, where the same rocket engine used for the Diagnostic Testbed Facility has since performed many test projects.
The Diagnostic Testbed Facility thruster also has been used for various projects at E-3, most recently in a project for the exploration upper stage being built for use on future Artemis missions.
In addition to hardware, engineers who worked at the Diagnostic Testbed Facility also moved on to support E Test Complex projects. There, they helped new NASA engineers learn how to handle gaseous hydrogen and liquid hydrogen propellants. Engineers learned about purging, ignition, and handling propellants and all the components needed for a successful test.
“From an engineering perspective, the more knowledge you have of the processes and procedures to make propulsion work, the better off you are,” Varner said. “It applied then and still applies today. The Diagnostic Testbed Facility contributed to the future development of NASA Stennis infrastructure and expertise.”
