This article is from the 2024 Technical Update.

The NESC evaluated material compatibility of some common aerospace metals in monomethylhydrazine (MMH) and nitrogen tetroxide (MON-3). Previous work had identified a lack of quantitative compatibility data for nickel alloy 718, 300 series stainless steel, and titanium Ti-6Al-4V in MMH and MON-3 to support the use of zero-failure-tolerant, thin-walled pressure barriers in these propellants. Static (i.e., not flowing) general corrosion and electrochemistry testing was conducted, evaluating varied processing forms and heat treatment of the metals, water content of propellant, and exposure duration. Corrosion-rate data for all tested product forms, fluids, and durations were on the order of 1 x 10–6 inch per year rather than the previously documented “less than 1 x 10–3 inch per year”. The majority of the corrosion products were seen in the first 20 days of exposure, with an overall corrosion rate decreasing with time due to the increased divisor (time). It is therefore recommended that corrosion testing be performed at multiple short-term durations to inform the need for longer-duration testing.

Background
Nickel alloy 718, 300 series stainless steel, and Ti-6Al-4V are commonly used in storable propulsion systems (i.e., MMH/MON-3), but a concern was raised regarding what quantitative compatibility data were available for proposed zero-failure-tolerant, thin-walled (~0.005 to 0.010 inch thickness) pressure barrier designs. A literature search found that limited and conflicting data were available for commonly used aerospace metals in MMH and MON-3. For example, corrosion behavior was listed qualitatively (e.g., “A” rating), data on materials and fluids tested were imprecise, fluids were identified as contaminated without describing how they were contaminated, no compatibility data were found on relevant geometry specimens (i.e., very thin-walled or convoluted), and limited data were available to quantify differences between tested materials and flight components. When corrosion data were quantified, documented sensitivity was “1 x 10–3 inch per year or less”, which is insufficient for assessing long-duration, thin-walled, flight-weight applications.

Discussion
General corrosion testing was performed with a static/non-flowing configuration based on NASA-STD-6001, Test 15 [1]. Design of experiments methods were used to develop a test matrix varying material, propellant, propellant water content, and tested duration. Materials tested were nickel alloy 718 (solution annealed sheet, aged sheet, aged/welded sheet, and hydroformed bellows), 300 series stainless steel (low carbon sheet, titanium stabilized sheet, and hydroformed bellows), and Ti 6Al-4V sheet. Samples were tested in sealed test tubes in MMH and MON-3 with water content ranging from as-received (“dry”) up to specification allowable limits [2,3]. Tested durations ranged from 20 to 365 days. Measurements included inductively coupled plasma mass spectrometry (ICPMS) to identify corrosion products and their concentrations in test fluid, gravimetric (i.e., scale) measurements pre- and post-exposure, and visual inspection. Bimetallic pairs (titanium stabilized 300 series stainless steel: Ti 6Al-4V and nickel alloy 718: Ti 6Al-4V) were tested for up to 65 days in both MMH and MON-3. The test setup incorporated important features of the test standard (e.g., electrode spacing and finish) and adapted the configuration for MMH/MON-3 operation. Measurements included potential difference and current flow between samples. Figure 1 shows images of the general corrosion and bimetallic pair test setups.

Test Results
For all tested materials and product forms, corrosion rates were on the order of 1 x 10–6 inch per year in MMH or MON-3, three orders of magnitude lower than historically reported. Corrosion products were generated in the first 20 days of exposure, and corrosion rate decreased with time due to the increase in divisor (i.e., time). Corrosion products increased as the water content of the propellants increased but remained in the same order of magnitude between the as-received dry propellant and propellant containing the maximum water content allowed by specification. Figure 2 illustrates test results for corrosion rate, mass loss with duration, and mass loss with water content. It is important to note that water has been demonstrated to contribute to flow decay even when water is within the specification allowable limit, and previous NASA-STD-6001 Test 15 data have demonstrated susceptibility of some nickel alloys to crevice-type corrosion attack [4]. Therefore, these results do not reduce the importance of considering the system impact of water content and evaluating for crevice corrosion behavior. Finally, in the bimetallic pair testing, tested materials did not measurably corrode in MON-3 and MMH within specification-allowable water content, as evidenced by no visual indications of corrosion and very low electrical interaction (i.e., corrosion rates derived to be less than 1 microinch per year from electrical interaction).

Recommendations
It is recommended that corrosion testing be performed at multiple shortterm durations to inform the need for longer-duration testing.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      Robert Mosher, HIAD materials and processing lead at NASA Langley, holds up a piece of webbing material, known as Zylon, which comprise the straps of the HIAD.NASA/Joe Atkinson Components of a NASA technology that could one day help crew and cargo enter harsh planetary environments, like that of Mars, are taking an extended trip to space courtesy of the United States Space Force.
      On Aug. 21, several pieces of webbing material, known as Zylon, which comprise the straps of the HIAD (Hypersonic Inflatable Aerodynamic Decelerator) aeroshell developed by NASA’s Langley Research Center in Hampton, Virginia, launched to low Earth orbit along with other experiments aboard the Space Force’s X-37B Orbital Test Vehicle. This trip will help researchers characterize how the Zylon webbing responds to long-duration exposure to the harsh vacuum of space.
      The strap material on the HIAD aeroshell serves two purposes – short strap lengths hold together HIAD’s inflatable rings and longer pieces help to distribute the load more evenly across the cone-shaped structure. The HIAD aeroshell technology could allow larger spacecraft to safely descend through the atmospheres of celestial bodies like Mars, Venus, and even Saturn’s moon, Titan.
      “We’re researching how HIAD technology could help get humans to Mars. We want to look at the effects of long-term exposure to space – as if the Zylon material is going for a potential six to nine-month mission to Mars,” said Robert Mosher, HIAD materials and processing lead at NASA Langley. “We want to make sure we know how to protect those structural materials in the long term.”
      The Zylon straps are visible here during the inflation of LOFTID as part of a November 2022 orbital flight test. LOFTID was a version of the HIAD aeroshell — a technology that could allow larger spacecraft to safely descend through the atmospheres of celestial bodies like Mars, Venus, and even Saturn’s moon, Titan.NASA Flying Zylon material aboard the Space Force’s X-37B mission will help NASA researchers understand what kind of aging might occur to the webbing on a long space journey before it experiences the extreme environments of atmospheric entry, during which it has to retain strength at high temperatures.
      Multiple samples are in small canisters on the X-37B. Mosher used two different techniques to put the strap material in the canisters. Some he tightly coiled up, others he stuffed in.
      “Typically, we pack a HIAD aeroshell kind of like you pack a parachute, so they’re compressed,” he said. “We wanted to see if there was a difference between tightly coiled material and stuff-packed material like you would normally see on a HIAD.”
      Some of the canisters also include tiny temperature and humidity sensors set to collect readings at regular intervals. When the Space Force returns the samples from the X-37B flight, Mosher will compare them to a set of samples that have remained in canisters here on Earth to look for signs of degradation.
      The material launched to space aboard the Space Force’s X-37B Orbital Test Vehicle, seen here earlier this year.Courtesy of the United States Space Force “Getting this chance to have the Zylon material exposed to space for an extended period of time will begin to give us some data on the long-term packing of a HIAD,” Mosher said.
      Uninflated HIAD aeroshells can be packed into small spaces within a spacecraft. This results in a decelerator that can be much larger than the diameter of its launch vehicle and can therefore land much heavier loads and deliver them to higher elevations on a planet or other celestial body.
      Rigid aeroshells, the sizes of which are dictated by the diameters of their launch vehicles, typically 4.5 to 5 meters, are capable of landing well-equipped, car-sized rovers on Mars. By contrast, an inflatable HIAD, with an 18-20m diameter, could land the equivalent of a small, fully furnished ranch house with a car in the garage on Mars.
      NASA’s HIAD aeroshell developments build on the success of the agency’s LOFTID (Low-Earth Orbit Flight Test of an Inflatable Decelerator) mission that launched on Nov. 10, 2022, resulting in valuable insights into how this technology performs under the stress of re-entering Earth’s atmosphere after being exposed to space for a short time period.

      A collage of artist concepts highlighting the novel approaches proposed by the 2025 NIAC awardees for possible future missions. Through the NASA Innovative Advanced Concepts (NIAC) program, NASA nurtures visionary yet credible concepts that could one day “change the possible” in aerospace, while engaging America’s innovators and entrepreneurs as partners in the journey.  
      These concepts span various disciplines and aim to advance capabilities such as finding resources on distant planets, making space travel safer and more efficient, and even providing benefits to life here on Earth. The NIAC portfolio of studies also includes several solutions and technologies that could help NASA achieve a future human presence on Mars. One concept at a time, NIAC is taking technology concepts from science fiction to reality.  
      Breathing beyond Earth 
      Astronauts have a limited supply of water and oxygen in space, which makes producing and maintaining these resources extremely valuable. One NIAC study investigates a system to separate oxygen and hydrogen gas bubbles in microgravity from water, without touching the water directly. Researchers found the concept can handle power changes, requires less clean water, works in a wide range of temperatures, and is more resistant to bacteria than existing oxygen generation systems for short-term crewed missions. These new developments could make it a great fit for a long trip to Mars.  
      Newly selected for another phase of study, the team wants to understand how the system will perform over long periods in space and consider ways to simplify the system’s build. They plan to test a large version of the system in microgravity in hopes of proving how it may be a game changer for future missions. 
      Detoxifying water on Mars
      Unlike water on Earth, Mars’ water is contaminated with toxic chemical compounds such as perchlorates and chlorates. These contaminants threaten human health even at tiny concentrations and can easily corrode hardware and equipment. Finding a way to remove contaminates from water will benefit future human explorers and prepare them to live on Mars long term. 
      Researchers are creating a regenerative perchlorate reduction system that uses perchlorate reduction pathways from naturally occurring bacteria. Perchlorate is a compound comprised of oxygen and chlorine that is typically used for rocket propellant. These perchlorate reduction pathways can be engineered into a type of bacterium that is known for its remarkable resilience, even in the harsh conditions of space. The system would use these enzymes to cause the biochemical reduction of chlorate and perchlorate to chloride and oxygen, eliminating these toxic molecules from the water. With the technology to detoxify water on Mars, humans could thrive on the Red Planet with an abundant water supply. 
      Tackling deep space radiation exposure 
      Mitochondria are the small structures within cells often called the “powerhouse,” but what if they could also power human health in space? Chronic radiation exposure is among the many threats to long-term human stays in space, including time spent traveling to and from Mars. One NIAC study explores transplanting new, undamaged mitochondria to radiation-damaged cells and investigates cell responses to relevant radiation levels to simulate deep-space travel. Researchers propose using in vitro human cell models – complex 3D structures grown in a lab to mimic aspects of organs – to demonstrate how targeted mitochondria replacement therapy could regenerate cellular function after acute and long-term radiation exposure.  
      While still in early stages, the research could help significantly reduce radiation risks for crewed missions to Mars and beyond. Here on Earth, the technology could also help treat a wide variety of age-related degenerative diseases associated with mitochondrial dysfunction. 
      Suiting up for Mars 
      Mars is no “walk in the park,” which is why specialized spacesuits are essential for future missions. Engineers propose using a digital template to generate custom, cost-effective, high-performance spacesuits. This spacesuit concept uses something called digital thread technology to protect crewmembers from the extreme Martian environment, while providing the mobility to perform daily Mars exploration endeavors, including scientific excursions. 
      This now completed NIAC study focused on mapping key spacesuit components and current manufacturing technologies to digital components, identifying technology gaps, benchmarking required capabilities, and developing a conceptional digital thread model for future spacesuit development and operational support. This research could help astronauts suit up for Mars and beyond in a way like never before.   
      Redefining what’s possible 
      From studying Mars to researching black holes and monitoring the atmosphere of Venus, NIAC concepts help us push the boundaries of exploration. By collaborating with innovators and entrepreneurs, NASA advances concepts for future and current missions while energizing the space economy.  
      If you have a visionary idea to share, you can apply to NIAC’s 2026 Phase I solicitation now until July 15.

      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.

      NASA Interns Conduct Aerospace Research in Microgravity
      The NASA Science Activation program’s STEM (Science, Technology, Engineering, and Mathematics) Enhancement in Earth Science (SEES) Summer Intern Program, hosted by the University of Texas Center for Space Research, continues to expand opportunities for high school students to engage in authentic spaceflight research. As part of the SEES Microgravity Research initiative, four interns were selected to fly with their experiments in microgravity aboard the ZERO-G parabolic aircraft. The students had 11 minutes of weightlessness over 30 parabolas in which to conduct their experiments.
      This immersive experience was made possible through a collaboration between SEES, Space for Teachers, the Wisconsin Space Grant Consortium, and the International Space Station National Laboratory (CASIS). Together, these partners provide students with access to industry-aligned training and direct experience in aerospace experiment design, testing, and integration.
      Congratulations to the 2025 SEES Microgravity Research Team:
      Charlee Chandler, 11th grade, Rehobeth High School (Dothan, AL): Galvanic Vestibular Stimulation (GVS) and Vestibular-Ocular Reflex (VOR) in Microgravity Aya Elamrani-Zerifi, 11th grade, Hereford High School (Parkton, MD): Thermocapillary-Induced Bubble Dynamics Lily Myers, 12th grade, Eastlake High School (Sammamish, WA): Propellant Slosh Damping Using Polyurethane Foam Nathan Scalf 11th grade, Lexington Christian Academy (Lexington, KY): Wound Irrigation System for Microgravity Selected from nearly 100 proposals submitted by 2024 SEES interns, these four students spent months preparing for flight through weekly technical mentorship and structured milestones. Their training included proposal development, design reviews, safety assessments, hardware testing, and a full payload integration process, working through engineering protocols aligned with industry and mission standards.
      In addition to their individual experiments, the students also supported the flight of 12 team-designed experiments integrated into the ZQube platform, a compact research carrier co-developed by Twiggs Space Lab, Space for Teachers, and NASA SEES. The ZQube enables over 150 SEES interns from across the country to contribute to microgravity investigations. Each autonomous experiment includes onboard sensors, cameras, and transparent test chambers, returning valuable video and sensor data for post-flight analysis.
      This microgravity research opportunity supports the broader SEES mission to prepare students for careers in aerospace, spaceflight engineering, and scientific research. Through direct engagement with NASA scientists, academic mentors, and commercial aerospace experts, students gain real-world insight into systems engineering and the technical disciplines needed in today’s space industry.
      The SEES summer intern program is a nationally competitive STEM experience for 10th-11th grade high school students. Interns learn how to interpret NASA satellite data while working with scientists and engineers in their chosen area of work, including astronomy, remote sensing, and space geodetic techniques to help understand Earth systems, natural hazards, and climate. It is supported by NASA under cooperative agreement award number NNH15ZDA004C and is part of NASA’s Science Activation Portfolio.
