Preparations for Next Moonwalk Simulations Underway (and Underwater)
Tim Stiglets’ work at NASA’s Stennis Space Center gives him a front-row seat to the growth and opportunity potential of NASA Stennis. His work ranges from managing data for how a test stand is configured to tracking the configuration of NASA Stennis buildings and utilities systems that make up the infrastructure for America’s largest rocket propulsion test site.NASA/Danny Nowlin Two words come to Tim Stiglets’ mind when he thinks about NASA’s Stennis Space Center near Bay St. Louis, Mississippi – growth and opportunity.
The Waveland, Mississippi, resident has experienced both in his career at the south Mississippi NASA center.
He started as a summer intern onsite with Lockheed Martin in 2002. When The University of Southern Mississippi graduate joined the NASA team in 2019, he really started to understand how much activity happens at the unique federal city.
NASA Stennis is home to more than 50 companies and organizations sharing in site operating costs.
As a management and program analyst in the NASA Stennis Engineering and Test Directorate, Stiglets serves as the manager of the Product Lifecycle Management (PLM) Program. He describes the program as a one-stop shop for engineering data.
Product lifecycle management (PLM) consists of technology, people, processes, and tools to track a product throughout its lifecycle.
Think of it in terms of building a LEGO set. From the time one gets the idea of building the set, to when it is finished, played with, and taken apart, there is a lot to track.
Stiglets’ work involves much bigger pieces, ranging from managing data for how a test stand is configured to tracking the configuration of NASA Stennis buildings and utilities systems that make up the infrastructure for America’s largest rocket propulsion test site. NASA Stennis facilities are valued at more than $2 billion.
His work gives him a front-row seat to the growth and opportunity potential of NASA Stennis.
“The cool thing about PLM is I get to be involved, in some small way, with NASA’s Artemis work, commercial test customers and all the Center Operations projects that support the federal city,” he said.
The center tests rocket engines and stages to power future Artemis missions to the Moon and beyond. NASA Stennis also works with such commercial test customers as Relativity Space, Blue Origin, Rolls-Royce, Evolution Space, and Vast (formerly Launcher Space).
“PLM is a center capability that we have evolved, so it does not matter if it is a water system, a test stand or building that is involved. It all kind of relies on, and ultimately somewhere down the line, hits the PLM system that has the drawings and engineering data needed for the project. That is probably the coolest thing about my work. I get to see a lot of different things that are going on in different areas.”
Stiglets said it feels like every time he turns around, there is someone leasing a new building or joining the NASA Stennis federal city. The center has lease agreements for use of land and infrastructure with Relativity Space, Rocket Lab, and Evolution Space.
“We have a get-it-done kind of attitude,” Stiglets said. “We are going to do whatever it takes to get the job done. If it is testing engines or anything else, we are going to get it done. From a propulsion testing standpoint, commercial companies that lease areas onsite can come in and have access to contract support and to the NASA folks who have decades worth of knowledge. The companies can leverage all of that expertise and tap into the knowledge.”
The Long Beach, Mississippi, native speaks with enthusiasm when describing his time at NASA Stennis, where growth and opportunity continue forward.
“How cool is it to work for NASA, even coming in as a contractor,” Stiglets said. “You get to be involved with something bigger and much beyond south Mississippi. The excitement of being involved with NASA so many years ago was very cool for me, especially being a college student. I still have that same excitement. Many years have passed, and day-to-day work changes, but ultimately, you are still looking to achieve big goals.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Typically, asteroids — like the one depicted in this artist’s concept — originate from the main asteroid belt between the orbits of Mars and Jupiter, but a small population of near-Earth objects may also come from the Moon’s surface after being ejected into space by an impact.NASA/JPL-Caltech The near-Earth object was likely ejected into space after an impact thousands of years ago. Now it could contribute new insights to asteroid and lunar science.
The small near-Earth object 2024 PT5 captured the world’s attention last year after a NASA-funded telescope discovered it lingering close to, but never orbiting, our planet for several months. The asteroid, which is about 33 feet (10 meters) wide, does not pose a hazard to Earth, but its orbit around the Sun closely matches that of our planet, hinting that it may have originated nearby.
As described in a study published Jan. 14 in the Astrophysical Journal Letters, researchers have collected further evidence of 2024 PT5 being of local origin: It appears to be composed of rock broken off from the Moon’s surface and ejected into space after a large impact.
“We had a general idea that this asteroid may have come from the Moon, but the smoking gun was when we found out that it was rich in silicate minerals — not the kind that are seen on asteroids but those that have been found in lunar rock samples,” said Teddy Kareta, an astronomer at Lowell Observatory in Arizona, who led the research. “It looks like it hasn’t been in space for very long, maybe just a few thousand years or so, as there’s a lack of space weathering that would have caused its spectrum to redden.”
The asteroid was first detected on Aug. 7, 2024, by the NASA-funded Sutherland, South Africa, telescope of the University of Hawai’i’s Asteroid Terrestrial-impact Last Alert System (ATLAS). Kareta’s team then used observations from the Lowell Discovery Telescope and the NASA Infrared Telescope Facility (IRTF) at the Mauna Kea Observatory in Hawai’i to show that the spectrum of reflected sunlight from the small object’s surface didn’t match that of any known asteroid type; instead, the reflected light more closely matched rock from the Moon.
Not (Old) Rocket Science
A second clue came from observing how the object moves. Along with asteroids, Space Age debris, such as old rockets from historic launches, can also be found in Earth-like orbits.
The difference in their orbits has to do with how each type responds to solar radiation pressure, which comes from the momentum of photons — quantum particles of light from the Sun — exerting a tiny force when they hit a solid object in space. This momentum exchange from many photons over time can push an object around ever so slightly, speeding it up or slowing it down. While a human-made object, like a hollow rocket booster, will move like an empty tin can in the wind, a natural object, such as an asteroid, will be much less affected.
Researchers studying asteroid 2024 PT5 have plotted its looping motion on two graphs. To a trained eye, they show that the object never gets captured by Earth’s gravity but, instead, lingers nearby before continuing its orbit around the Sun. NASA/JPL-Caltech To rule out 2024 PT5 being space junk, scientists at NASA’s Center for Near Earth Object Studies (CNEOS), which is managed by the agency’s Jet Propulsion Laboratory in Southern California, analyzed its motion. Their precise calculations of the object’s motion under the force of gravity ultimately enabled them to search for additional motion caused by solar radiation pressure. In this case, the effects were found to be too small for the object to be artificial, proving 2024 PT5 is most likely of natural origin.
“Space debris and space rocks move slightly differently in space,” said Oscar Fuentes-Muñoz, a study coauthor and NASA postdoctoral fellow at JPL working with the CNEOS team. “Human-made debris is usually relatively light and gets pushed around by the pressure of sunlight. That 2024 PT5 doesn’t move this way indicates it is much denser than space debris.”
Asteroid Lunar Studies
The discovery of 2024 PT5 doubles the number of known asteroids thought to originate from the Moon. Asteroid 469219 Kamo’oalewa was found in 2016 with an Earth-like orbit around the Sun, indicating that it may also have been ejected from the lunar surface after a large impact. As telescopes become more sensitive to smaller asteroids, more potential Moon boulders will be discovered, creating an exciting opportunity not only for scientists studying a rare population of asteroids, but also for scientists studying the Moon.
If a lunar asteroid can be directly linked to a specific impact crater on the Moon, studying it could lend insights into cratering processes on the pockmarked lunar surface. Also, material from deep below the lunar surface — in the form of asteroids passing close to Earth — may be accessible to future scientists to study.
“This is a story about the Moon as told by asteroid scientists,” said Kareta. “It’s a rare situation where we’ve gone out to study an asteroid but then strayed into new territory in terms of the questions we can ask of 2024 PT5.”
The ATLAS, IRTF, and CNEOS projects are funded by NASA’s planetary defense program, which is managed by the Planetary Defense Coordination Office at NASA Headquarters in Washington.

Climate change presents one of the most urgent crises of our time, with increasing threats to life, infrastructure, economies, and ecosystems worldwide. Climate change is no longer a distant concern; its effects are being felt now and are projected to intensify if emissions continue unabated. The consequences are severe and irreversible for people today, with rapidly shrinking glaciers and ice sheets, rising sea levels, and more intense heat waves already occurring. Scientists predict even more profound impacts, such as an increase in the frequency and intensity of wildfires, extended drought periods, and stronger tropical cyclones. By 2100, sea levels could rise by up to 6.5 feet1, displacing coastal communities and disrupting ecosystems. In the U.S., the effects vary by region—wildfires in the West have doubled in area burned, and rising sea levels threaten infrastructure in the Southeast. Innovative, data-driven solutions are essential to mitigate these growing risks. From the unique vantage point in space, NASA collects critical long-term observations of our changing planet. NASA produces vast amounts of Earth system science data from satellites, radars, and ships, as well as model outputs, offering a wealth of opportunities for innovative thinkers to leverage these sources. The Sustainable Business Model Challenge is designed to identify and foster sustainable business models built around NASA’s Earth system science data. This challenge invites entrepreneurs, researchers, startups, and innovators to use NASA’s publicly available climate and Earth system data sources to create sustainable business models to address climate challenges.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
2025 Seminar Series
Throughout 2025, the NASA History Office is presenting a seminar series on the topic of Aerospace Latin America. This series will explore the origins, evolution, and historical context of aerospace in the region since the dawn of the Space Age, touching on a broad range of topics including aerospace infrastructure development, space policy and law, Earth science applications, and much more.
This seminar series is part of a collaborative effort to gather insights and research that will conclude in an anthology of essays to be published as a NASA History Special Publication. Individual presentations will be held virtually bi-weekly or monthly.
During a gravity assist in 1992, the Galileo spacecraft took images of Earth and the Moon. Separate images were combined to generate this composite which features a view of the Pacific Ocean and Central and South America.NASA/JPL/USGS Upcoming Presentations
“Governing the Moon: A History”
Stephen Buono (University of Chicago)
Thursday, February 6 at 1pm CST
In this talk, Stephen Buono will provide a nuanced history of the unratified Agreement Governing the Activities of States on the Moon and Other Celestial Bodies, more commonly known as the Moon Treaty. Buono will illuminate the treaty’s deep origins, the contributions of international space lawyers, the details of the negotiating process, the role played by the United States in shaping the final text, and the contributions of the treaty’s single most important author, Argentine lawyer, Aldo Armando Cocca.
“A God’s Eye View: Aviators and the Re-Conquest of Latin America”
Pete Soland(University of Houston—Downtown)
Thursday, February 20 at 1pm CST
This talk scrutinizes the aviator-conquistador metaphor. It examines airplane pilots as personifying high modernism and the technological sublime in Latin America from the turn of the century through the early Space Age, when spaceships and astronauts eclipsed airplanes and aviators. Repeated invocations of the conquistador as a metaphor for the aviator’s social role–and the conquest as an analogy for the goals of aviation programs–illustrate how elites promoted their modernization initiatives to national publics.
