Robert Williams is a senior mechanical design engineer and the structures subject matter expert in the Engineering and Test Directorate at NASA’s Stennis Space Center.NASA/Danny Nowlin Living up to, and maintaining, the standard of excellence associated with NASA is what drives Robert Williams at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.
A native of Gulfport, Mississippi, Williams said he has had the opportunity to work with and be mentored by “some truly exceptional” engineers, some with careers reaching back to the Apollo era.
“I cannot overstate the vast amount of practical knowledge and experience we have at NASA Stennis,” Williams said. “We know how to get things done, and if we do not know, I can guarantee we will figure it out.”
Williams is a senior mechanical design engineer and the structures subject matter expert for the NASA Stennis Engineering and Test Directorate.
He provides technical oversight related to engineering mechanics and machine design by reviewing analysis and design packages from NASA Stennis contractors and NASA engineers for ongoing projects.
Williams also supports projects by performing analysis and creating detailed models, drawings, and system level designs, mostly at the versatile four-stand E Test Complex, where NASA Stennis has 12 active test cells capable of various component, engine, and stage test activities to support the agency and commercial companies.
In support of NASA’s Artemis campaign of returning astronauts to the Moon, Williams also has reviewed structural and pipe stress analysis for the exploration upper stage project that will test a new SLS (Space Launch System) rocket stage to fly on future Artemis missions.
He performed similar review work for Green Run testing of the SLS core stage at NASA Stennis ahead of the successful launch of the Artemis I uncrewed mission around the Moon.
Overall, Williams has been a part of projects on every test stand throughout more than eight years with NASA and five years as a contractor. He has been tasked with solving challenging problems, both individually and as a part of teams.
There were times when he was not sure if he or the team would be able to solve the problem or address it effectively, but each time, the NASA Stennis team found a way.
“Over the span of my career, I have yet to be in a situation where the challenge was not met,” he said.
The opportunity to work with “pretty much all the major space companies in some capacity” is most interesting to Williams. “The best thing is that being a small organization within a relatively small center, there are always opportunities to develop new skills and capabilities to help fill a need or gap,” he said.
No matter the task, Williams looks forward to supporting space innovation while living up to, and maintaining, the standard of excellence associated with NASA for the benefit of all.

Landing on the Moon is not easy, particularly when a crew or spacecraft must meet exacting requirements. For Artemis missions to the lunar surface, those requirements include an ability to land within an area about as wide as a football field in any lighting condition amid tough terrain.
NASA’s official lunar landing requirement is to be able to land within 50 meters (164 feet) of the targeted site and developing precision tools and technologies is critically important to mission success.
NASA engineers recently took a major step toward safe and precise landings on the Moon – and eventually Mars and icy worlds – with a successful field test of hazard detection technology at NASA’s Kennedy Space Center Shuttle Landing Facility in Florida.
A joint team from the Aeroscience and Flight Mechanics Division at NASA’s Johnson Space Center’s in Houston and Goddard Space Flight Center in Greenbelt, Maryland, achieved this huge milestone in tests of the Goddard Hazard Detection Lidar from a helicopter at Kennedy in March 2025.
NASA’s Hazard Detection Lidar field test team at Kennedy Space Center’s Shuttle Landing Facility in Florida in March 2025. NASA The new lidar system is one of several sensors being developed as part of NASA’s Safe & Precise Landing – Integrated Capabilities Evolution (SPLICE) Program, a Johnson-managed cross-agency initiative under the Space Technology Mission Directorate to develop next-generation landing technologies for planetary exploration. SPLICE is an integrated descent and landing system composed of avionics, sensors, and algorithms that support specialized navigation, guidance, and image processing techniques. SPLICE is designed to enable landing in hard-to-reach and unknown areas that are of potentially high scientific interest.
The lidar system, which can map an area equivalent to two football fields in just two seconds, is a crucial program component. In real time and compensating for lander motion, it processes 15 million short pulses of laser light to quickly scan surfaces and create real-time, 3D maps of landing sites to support precision landing and hazard avoidance.
Those maps will be read by the SPLICE Descent and Landing Computer, a high-performance multicore computer processor unit that analyzes all SPLICE sensor data and determines the spacecraft’s velocity, altitude, and terrain hazards. It also computes the hazards and determines a safe landing location. The computer was developed by the Avionics Systems Division at Johnson as a platform to test navigation, guidance, and flight software. It previously flew on Blue Origin’s New Shepard booster rocket.
The NASA team prepares the Descent and Landing Computer for Hazard Detection Lidar field testing at Kennedy Space Center. NASA For the field test at Kennedy, Johnson led test operations and provided avionics and guidance, navigation, and control support. Engineers updated the computer’s firmware and software to support command and data interfacing with the lidar system. Team members from Johnson’s Flight Mechanics branch also designed a simplified motion compensation algorithm and NASA’s Jet Propulsion Laboratory in Southern California contributed a hazard detection algorithm, both of which were added to the lidar software by Goddard. Support from NASA contractors Draper Laboratories and Jacobs Engineering played key roles in the test’s success.
Primary flight test objectives were achieved on the first day of testing, allowing the lidar team time to explore different settings and firmware updates to improve system performance. The data confirmed the sensor’s capability in a challenging, vibration-heavy environment, producing usable maps. Preliminary review of the recorded sensor data shows excellent reconstruction of the hazard field terrain.

NASA Beyond lunar applications, SPLICE technologies are being considered for use on Mars Sample Return, the Europa Lander, Commercial Lunar Payload Services flights, and Gateway. The DLC design is also being evaluated for potential avionics upgrades on Artemis systems.
Additionally, SPLICE is supporting software tests for the Advancement of Geometric Methods for Active Terrain Relative Navigation (ATRN) Center Innovation Fund project, which is also part of Johnson’s Aeroscience and Flight Mechanics Division. The ATRN is working to develop algorithms and software that can use data from any active sensor – one measuring signals that were reflected, refracted, or scattered by a body’s surface or its atmosphere – to accurately map terrain and provide absolute and relative location information. With this type of system in place, spacecraft will not need external lighting sources to find landing sites.
With additional suborbital flight tests planned through 2026, the SPLICE team is laying the groundwork for safer, more autonomous landings on the Moon, Mars, and beyond. As NASA prepares for its next era of exploration, SPLICE will be a key part of the agency’s evolving landing, guidance, and navigation capabilities.

Intuitive Machines’ IM-2 captured an image March 6, 2025, after landing in a crater from the Moon’s South Pole. The lunar lander is on its side near the intended landing site, Mons Mouton. In the center of the image between the two lander legs is the Polar Resources Ice Mining Experiment 1 suite, which shows the drill deployed.Intuitive Machines NASA’s PRIME-1 (Polar Resources Ice Mining Experiment 1) mission was designed to demonstrate technologies to help scientists better understand lunar resources ahead of crewed Artemis missions to the Moon. During the short-lived mission on the Moon, the performance of PRIME-1’s technology gave NASA teams reason to celebrate.
“The PRIME-1 mission proved that our hardware works in the harshest environment we’ve ever tested it in,” said Janine Captain, PRIME-1 co-principal investigator and research chemist at NASA’s Kennedy Space Center in Florida. “While it may not have gone exactly to plan, this is a huge step forward as we prepare to send astronauts back to the Moon and build a sustainable future there.”
Intuitive Machines’ IM-2 mission launched to the Moon on Feb. 26, 2025, from NASA Kennedy’s Launch Complex 39A, as part of the company’s second Moon delivery for NASA under the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign. The IM-2 Nova-C lunar lander, named Athena, carried PRIME-1 and its suite of two instruments: a drill known as TRIDENT (The Regolith and Ice Drill for Exploring New Terrain), designed to bring lunar soil to the surface; and a mass spectrometer, Mass Spectrometer Observing Lunar Operations (MSOLO), to study TRIDENT’s drill cuttings for the presence of gases that could one day help provide propellant or breathable oxygen to future Artemis explorers.
The IM-2 mission touched down on the lunar surface on March 6, just around 1,300 feet (400 meters) from its intended landing site of Mons Mouton, a lunar plateau near the Moon’s South Pole. The Athena lander was resting on its side inside a crater preventing it from recharging its solar cells, resulting in an end of the mission.
“We were supposed to have 10 days of operation on the Moon, and what we got was closer to 10 hours,” said Julie Kleinhenz, NASA’s lead systems engineer for PRIME-1, as well as the in-situ resource utilization system capability lead deputy for the agency. “It was 10 hours more than most people get so I am thrilled to have been a part of it.”
Kleinhenz has spent nearly 20 years working on how to use lunar resources for sustained operations. In-situ resource utilization harnesses local natural resources at mission destinations. This enables fewer launches and resupply missions and significantly reduces the mass, cost, and risk of space exploration. With NASA poised to send humans back to the Moon and on to Mars, generating products for life support, propellants, construction, and energy from local materials will become increasingly important to future mission success.
“In-situ resource utilization is the key to unlocking long-term exploration, and PRIME-1 is helping us lay this foundation for future travelers.” Captain said.
The PRIME-1 technology also set out to answer questions about the properties of lunar regolith, such as soil strength. This data could help inform the design of in-situ resource utilization systems that would use local resources to create everything from landing pads to rocket fuel during Artemis and later missions.
“Once we got to the lunar surface, TRIDENT and MSOLO both started right up, and performed perfectly. From a technology demonstrations standpoint, 100% of the instruments worked.” Kleinhenz said.
The lightweight, low-power augering drill built by Honeybee Robotics, known as TRIDENT, is 1 meter long and features rotary and percussive actuators that convert energy into the force needed to drill. The drill was designed to stop at any depth as commanded from the ground and deposit its sample on the surface for analysis by MSOLO, a commercial off-the-shelf mass spectrometer modified by engineers and technicians at NASA Kennedy to withstand the harsh lunar environment. Designed to measure the composition of gases in the vicinity of the lunar lander, both from the lander and from the ambient exosphere, MSOLO can help NASA analyze the chemical makeup of the lunar soil and study water on the surface of the Moon.
Once on the Moon, the actuators on the drill performed as designed, completing multiple stages of movement necessary to drill into the lunar surface. Prompted by commands from technicians on Earth, the auger rotated, the drill extended to its full range, the percussion system performed a hammering motion, and the PRIME-1 team turned on an embedded core heater in the drill and used internal thermal sensors to monitor the temperature change.
While MSOLO was able to perform several scans to detect gases, researchers believe from the initial data that the gases detected were all anthropogenic, or human in origin, such as gases vented from spacecraft propellants and traces of Earth water. Data from PRIME-1 accounted for some of the approximately 7.5 gigabytes of data collected during the IM-2 mission, and researchers will continue to analyze the data in the coming months and publish the results.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Multinational corporations are using the M2M Intelligence platform in data centers and other settings. The system offers automated, secure communications on a ground-based global 5G network. Getty Images Artificial intelligence (AI) is advancing rapidly, as intelligent software proves capable of various tasks. The technology usually requires a “human in the loop” to train it and ensure accuracy. But long before the arrival of today’s generative artificial intelligence, a different kind of AI was born with the help of NASA’s Ames Research Center in California’s Silicon Valley — one that only exists between machines, running without any human intervention.
In 2006, Geoffrey Barnard founded Machine-to-Machine Intelligence Corp. (M2Mi) at Ames’ NASA Research Park, envisioning an automated, satellite-based communication network. NASA Ames established a Space Act Agreement with the company to develop artificial intelligence that would automate communications, privacy, security, and resiliency between satellites and ground-based computers.
Central to the technology was automating a problem-solving approach known as root cause analysis, which NASA has honed over decades. This methodology seeks to identify not only the immediate cause of a problem but also all the factors that contributed to the cause. This would allow a network to identify its own issues and fix itself.
NASA Ames’ director of nanotechnology at the time wanted to develop a communications network based on small, low-powered satellites, so Ames supported M2Mi in developing the necessary technology.
Barnard, now CEO and chief technology officer of Tiburon, California-based branch of M2Mi, said NASA’s support laid the foundation for his company, which employs the same technology in a ground-based network.
The company’s M2M Intelligence software performs secure, resilient, automated communications on a system that runs across hundreds of networks, connecting thousands of devices, many of which were not built to communicate with each other. The M2Mi company worked with Vodafone of Berkshire, England, to build a worldwide network across more than 500 smaller networks in over 190 countries. The companies M2M Wireless and TriGlobal have begun using M2M Intelligence for transportation logistics.
With NASA’s help, emerging industries are getting the boost they need to rapidly develop technologies to enhance our lives.
