Othmane Benafan is a NASA engineer whose work is literally reshaping how we use aerospace materials — he creates metals that can shape shift. Benafan, a materials research engineer at NASA’s Glenn Research Center in Cleveland, creates metals called shape memory alloys that are custom-made to solve some of the most pressing challenges of space exploration and aviation.
“A shape memory alloy starts off just like any other metal, except it has this wonderful property: it can remember shapes,” Benafan says. “You can bend it, you can deform it out of shape, and once you heat it, it returns to its shape.”
An alloy is a metal that’s created by combining two or more metallic elements. Shape memory alloys are functional metals. Unlike structural metals, which are fixed metal shapes used for construction or holding heavy objects, functional metals are valued for unique properties that enable them to carry out specific actions.
NASA often needs materials with special capabilities for use in aircraft and spacecraft components, spacesuits, and hardware designed for low-Earth orbit, the Moon, or Mars. But sometimes, the ideal material doesn’t exist. That’s where engineers like Benafan come in.
“We have requirements, and we come up with new materials to fulfill that function,” he said. The whole process begins with pen and paper, theories, and research to determine exactly what properties are needed and how those properties might be created. Then he and his teammates are ready to start making a new metal.
“It’s like a cooking show,” Benafan says. “We collect all the ingredients — in my case, the metals would be elements from the periodic table, like nickel, titanium, gold, copper, etc. — and we mix them together in quantities that satisfy the formula we came up with. And then we cook it.”
Othmane Benafan, a materials research engineer, develops a shape memory alloy in a laboratory at NASA’s Glenn Research Center in Cleveland. These elemental ingredients are melted in a container called a crucible, then poured into the required shape, such as a cylinder, plate, or tube. From there, it’s subjected to temperatures and pressures that shape and train the metal to change the way its atoms are arranged every time it’s heated or cooled.
Shape memory alloys created by Benafan and his colleagues have already proven useful in several applications. For example, the Shape Memory Alloy Reconfigurable Technology Vortex Generator (SMART VG) being tested on Boeing aircraft uses the torque generated by a heat-induced twisting motion to raise and lower a small, narrow piece of hardware installed on aircraft wings, resulting in reduced drag during cruise conditions. In space, the 2018 Advanced eLectrical Bus (ALBus) CubeSat technology demonstration mission included the use of a shape memory alloy to deploy the small satellite’s solar arrays and antennas. And Glenn’s Shape Memory Alloy Rock Splitters technology benefits mining and geothermal applications on Earth by breaking apart rocks without harming the surrounding environment. The shape memory alloy device is wrapped in a heater and inserted into a predrilled hole in the rock, and when the heater is activated, the alloy expands, creating intense pressure that drives the rock apart.
Benafan’s fascination with shape memory alloys started after he immigrated to the United States from Morocco at age 19. He began attending night classes at the Valencia Community College (now Valencia College), then went on to graduate from the University of Central Florida in Orlando. A professor did a demonstration on shape memory alloys and that changed Benafan’s life forever. Now, Benafan enjoys helping others understand related topics.
“Outside of work, one of the things I like to do most is make technology approachable to someone who may be interested but may not be experienced with it just yet. I do a lot of community outreach through camps or lectures in schools,” he said.
He believes a mentality of curiosity and a willingness to fail and learn are essential for aspiring engineers and encourages others to pursue their ideas and keep trying.
“You know, we grow up with that mindset of falling and standing up and trying again, and that same thing applies here,” Benafan said. “The idea is to be a problem solver. What are you trying to contribute? What problem do you want to solve to help humanity, to help Earth?”

Acting NASA Administrator Janet Petro and Anke Kaysser-Pyzalla, chair, Executive Board, DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt), signed an agreement June 16, 2025, to continue a partnership on space medicine research. With this agreement, DLR will provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.Credit: DLR While attending the Paris Air Show June 16, NASA acting Administrator Janet Petro signed an agreement with DLR (German Aerospace Center, or Deutsches Zentrum für Luft- und Raumfahrt) to continue a partnership in space medicine research. This renewed collaboration builds on previous radiation mitigation efforts for human spaceflight. As NASA advances the Trump-Vance Administration’s goals for exploration on the Moon and Mars, minimizing exposure to space radiation is one of the key areas the agency is working to protect crew on long duration missions.
With this agreement, DLR will leverage its human spaceflight expertise and provide new radiation sensors aboard the Orion spacecraft during NASA’s Artemis II mission, building on previous work in this area during the Artemis I mission. Scheduled for launch no later than April 2026, Artemis II will mark the first test flight with crew under Artemis.
“In keeping with the historic agreements NASA has made with international partners as a part of Artemis, I am pleased to sign a new NASA-DLR joint agreement today, to enable radiation research aboard Artemis II,” said acting NASA Administrator Janet Petro. “The German Aerospace Center has been a valuable partner in Artemis, having previously worked with NASA to test technology critical to our understanding of radiation on humans aboard an Orion spacecraft on Artemis I and providing a CubeSat as part of Artemis II. Following a productive meeting between President Trump and German Chancellor Merz earlier this month, I am excited to build upon our great partnership with Germany.”
During the Artemis II mission’s planned 10-day journey around the Moon and back, four of DLR’s newly developed M-42 extended (M-42 EXT) radiation detectors will be on board, contributing vital data to support astronaut safety. This next-generation device represents a new phase of research as NASA and DLR continue working together to safeguard human health in space.
Under the leadership of President Trump, America’s Artemis campaign has reignited NASA’s ambition, sparking international cooperation and cutting-edge innovation. The continued partnership with DLR and the deployment of their advanced M-42 EXT radiation detectors aboard Artemis II exemplifies how the Trump-Vance Administration is leading a Golden Era of Exploration and Innovation that puts American astronauts on the path to the Moon, Mars, and beyond.
“To develop effective protective measures against the impact of space radiation on the human body, comprehensive and coherent radiation measurements in open space are essential,” says Anke Pagels-Kerp, divisional board member for space at DLR. “At the end of 2022, Artemis I carried 12,000 passive and 16 active detectors inside the Helga and Zohar mannequins, which flew aboard the Orion spacecraft as part of DLR’s MARE project. These provided a valuable dataset – the first continuous radiation measurements ever recorded beyond low Earth orbit. We are now excited to take the next step together with NASA and send our upgraded radiation detectors around the Moon on the Artemis II mission.”
Through the Artemis campaign, the agency will establish a long-term presence on the Moon for scientific exploration with our commercial and international partners, learn how to live and work away from home, and prepare for future human exploration of Mars.

The book cover for the 2025 edition of the Microgravity Materials Research Researcher’s Guide June 2025 Edition
Most materials are formed from a partially or totally fluid sample, and the transport of heat and mass from the fluid into the solid during solidification inherently influences the formation of the material and its resultant properties. The ISS provides a long-duration microgravity environment for conducting experiments that enables researchers to examine the effects of heat and mass transport on materials processes in the near-absence of gravity-driven forces. The microgravity environment greatly reduces buoyancy-driven convection, hydrostatic pressure, and sedimentation. It can also be advantageous for designing experiments with reduced container interactions. The reduction in these gravity-related sources of heat and mass transport may be taken advantage of to determine how material processes and microstructure formation are affected by gravity-driven and gravity independent sources of heat and mass transfer.
Materials science experiments on the ISS have yielded broad and significant scientific advancements, including contributing to the development of improved mathematical models for predicting material properties during processing on Earth and enabling a better understanding of microstructure formation during solidification towards controlling the material properties of various alloys.
This researcher’s guide provides information on the acceleration environment of the space station and describes facilities available for materials research. Examples of previous microgravity materials research and descriptions of planned research are also provided.
