NASA/Loral O’Hara The Choctaw Heirloom Seeds investigation flew five varieties of heirloom seeds from the Choctaw Nation of Oklahoma aboard the International Space Station in early November 2023. The seeds are Isito (Choctaw Sweet Potato Squash), Tobi (Smith Peas), Tanchi Tohbi (Flour Corn), Tvnishi (Lambsquarter), and Chukfi Peas. The seeds spent six months aboard station, returning to Earth in April 2024.
Next spring, Jones Academy students will plant the space-flown seeds alongside Earth-bound seeds of the same type in the school’s Growing Hope Garden. Students will hypothesize how the seeds will grow and make observations throughout the growing season.
Middle school teachers are developing curriculum incorporating the seeds’ journey to space station and students’ experiments in the garden. This research could impact Native and Indigenous populations across the United States, inviting underrepresented groups to engage with science, technology, engineering, and mathematics.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
By Wayne Smith
As NASA plans for humans to return to the Moon and eventually explore Mars, a laser beam welding collaboration between NASA’s Marshall Space Flight Center in Huntsville, Alabama, and The Ohio State University in Columbus aims to stimulate in-space manufacturing.
Scientists and engineers from NASA’s Marshall Space Flight Center, participating in the laser beam welding study in August, stand in front of the parabolic plane used for testing. From left, Will Evans, Louise Littles, Emma Jaynes, Andrew O’Connor, and Jeffrey Sowards. Not pictured: Zachary Courtright.Casey Coughlin/Starlab-George Washington Carver Science Park The multi-year effort seeks to understand the physical processes of welding on the lunar surface, such as investigating the effects of laser beam welding in a combined vacuum and reduced gravity environment. The goal is to increase the capabilities of manufacturing in space to potentially assemble large structures or make repairs on the Moon, which will inform humanity’s next giant leap of sending astronauts to Mars and beyond.
“For a long time, we’ve used fasteners, rivets, or other mechanical means to keep structures that we assemble together in space,” said Andrew O’Connor, a Marshall materials scientist who is helping coordinate the collaborative effort and is NASA’s technical lead for the project. “But we’re starting to realize that if we really want strong joints and if we want structures to stay together when assembled on the lunar surface, we may need in-space welding.” The ability to weld structures in space would also eliminate the need to transport rivets and other materials, reducing payloads for space travel. That means learning how welds will perform in space.
To turn the effort into reality, researchers are gathering data on welding under simulated space conditions, such as temperature and heat transfer in a vacuum; the size and shape of the molten area under a laser beam; how the weld cross-section looks after it solidifies; and how mechanical properties change for welds performed in environmental conditions mimicking the lunar surface.
“Once you leave Earth, it becomes more difficult to test how the weld performs, so we are leveraging both experiments and computer modeling to predict welding in space while we’re still on the ground,” said O’Connor.
In August 2024, a joint team from Ohio State’s Welding Engineering and Multidisciplinary Capstone Programs and Marshall’s Materials & Processes Laboratory performed high-powered fiber laser beam welding aboard a commercial aircraft that simulated reduced gravity. The aircraft performed parabolic flight maneuvers that began in level flight, pulled up to add 8,000 feet in altitude, and pushed over at the top of a parabolic arc, resulting in approximately 20 seconds of reduced gravity to the passengers and experiments.
While floating in this weightless environment, team members performed laser welding experiments in a simulated environment similar to that of both low Earth orbit and lunar gravity. Analysis of data collected by a network of sensors during the tests will help researchers understand the effects of space environments on the welding process and welded material.
NASA Marshall engineers and scientists, along with their collaborators from Ohio State University, monitor laser beam welding in a vacuum chamber during a Boeing 727 parabolic flight. From left, Andrew O’Connor, Marshall materials scientist and NASA technical lead for the project; Louise Littles, Marshall materials scientist; and Aaron Brimmer, OSU graduate student.Tasha Dixon/Zero-G “During the flights we successfully completed 69 out of 70 welds in microgravity and lunar gravity conditions, realizing a fully successful flight campaign,” said Will McAuley, an Ohio State welding engineering student.
Funded in part by Marshall and spanning more than two years, the work involves undergraduate and graduate students and professors from Ohio State, and engineers across several NASA centers. Marshall personnel trained alongside the university team, learning how to operate the flight hardware and sharing valuable lessons from previous parabolic flight experiments. NASA’s Langley Research Center in Hampton, Virginia, developed a portable vacuum chamber to support testing efforts.
The last time NASA performed welding in space was during the Skylab mission in 1973. Other parabolic tests have since been performed, using low-powered lasers. Practical welding and joining methods and allied processes, including additive manufacturing, will be required to develop the in-space economy. These processes will repurpose and repair critical space infrastructure and could build structures too large to fit current launch payload volumes. In-space welding could expedite building large habitats in low Earth orbit, spacecraft structures that keep astronauts safe on future missions, and more.
The work is also relevant to understanding how laser beam welding occurs on Earth. Industries could use data to inform welding processes, which are critical to a host of manufactured goods from cars and refrigerators to skyscrapers.
“We’re really excited about laser beam welding because it gives us the flexibility to operate in different environments,” O’Connor said.
There has been a resurgence of interest in welding as we look for innovative ways to put larger structures on the surface of the Moon and other planets.
