NASA has a strong need for advanced materials and processes (M&P) across the realms of robotic- and crewed-spaceflight, as well as aeronautics, particularly when one acknowledges that all craft must be made of something. To meet that need, the materials discipline relies on collaboration—both between centers and across disciplines. Reaching the Agency’s Moon-to-Mars objectives will require leveraging each center’s specific M&P expertise, cross-training among the centers, and routinely interacting with the 20-plus Agency disciplines like structures, space environments, and loads and dynamics. When a discipline touches all classes of materials; all aspects of design, manufacturing, testing, and operations; and all phases of flight, collaboration is the only way to broaden and deepen its reach.
This year, the Materials TDT pulled in wide-ranging center and discipline support for the VIPER lunar rover, investigations of cracks in the ISS Russian PrK, the X-59 supersonic aircraft, and the SLS Program. It also leveraged its contamination control experience to aid the Commercial Crew and Orion Programs. Below are some additional highlights from the year.
Collaboration Among Disciplines
Ms. Alison Park, NASA Deputy Technical Fellow for Materials, led a multi-disciplinary NESC team to address JPL’s request for sup – port to investigate anomalous temperature readings during thermal vacuum testing of the NASA Indian Space Research Organization (ISRO) Synthetic Aperture Rader (NISAR) reflect-array hardware, already integrated onto the spacecraft in India. The team provided detailed reviews of the thermal models and supported materials testing and characterization of the reflect-array construction record. The team’s work identified operability concerns from higher than expected temperatures that would be seen during the multi-day deployment process. The hardware was demated from the space – craft and returned to the United States for design upgrades and modifications to address the new concerns. The hardware is now set to return to India for reintegration and final launch preparations.
Fostering Intercenter Cooperation
Mr. Robert Carter, NASA Deputy Technical Fellow for Materials and GRC Deputy Division Chief, attended a technical exchange between GRC and MSFC. The exchange uncovered the need for an Agency-wide, materials-driven alloy development plan to identify key needs that would benefit spaceflight and aeronautics. From there, materials representatives from 7 of the 10 centers met in-person to develop a roadmap and a plan to be released in FY25. The Materials TDT also stood up an Alloy Development Community of Practice to provide a grassroots mechanism to identify cross-Agency needs, technical challenges, and benefits that aren’t identified programmatically or within mission directorates.

The NASA Technical Fellow for Materials, Dr. Bryan W. McEnerney, hosted visitors from the European Space Agency (ESA) for a combined trip to JPL, GRC, and KSC, as well as the jointly organized Worldwide Advanced Manufacturing Symposium (WAMS) in Orlando, FL. In-depth technical interchanges between NASA and ESA emphasized advanced manufacturing with a focus on spaceflight needs. The event increased technical collaboration be – tween the two organizations, leading to ESA’s request to NASA for a formal review of ESA’s stress corrosion standard. Work was also initiated on a joint NASA/ESA intern program. Next year brings a number of new and exciting challenges, including an elevated temperature testing program focused on HallPetch effects in C-103 (niobium alloy), the domestic North American WAMS symposium in Knoxville, TN, and a continued focus on intercenter technical support. And, always a key objective, the discipline will actively engage early-career personnel on NESC assessments to learn from our veteran materials experts and to pass on the knowledge so unique to the space industry.

Ken Freeman (center) receives the ATCA Award for ATM-X Digital Information Platform (DIP) from Rachel Jackson, Chair ATCA Board of Directors (left) and Carey Fagan, President and CEO ATCA (right).NASA Air Traffic Control Association (ATCA) Award to the NASA ATM-X Digital Information Platform (DIP) Team
In November 2024, the Digital Information Platform (DIP) team received the prestigious Industry Award from the Air Traffic Control Association (ATCA) at the annual ATCA Connect Conference in Washington, DC. The award recognized the team’s efforts in supporting NASA’s Sustainable Flight National Partnership (SFNP), which aims for net-zero carbon emissions from aviation by 2050. The DIP sub-project focuses on increasing access to digital aviation information to enable efficient and sustainable airspace operations. DIP team has been conducting live operational demonstrations in North Texas Metroplex environment since 2022 with commercial airlines on the Collaborative Digital Departure Reroute (CDDR) tool that applies machine learning to make predictions on runway availability, departure times, and arrival times. DIP has signed Space Act Agreements with five major US airlines to carryout operational evaluation of CDDR in complex metroplex environments and is now deploying the CDDR capability to Houston. CDDR machine learning algorithm intelligently provides re-routing options to the operators by using real time weather and operational data reducing delays, fuel burn and carbon emissions. DIP is part of the Air Traffic Management – eXploration (ATM-X) project, which is focused on transforming the air traffic management system to accommodate new air vehicles.

NASA Goddard MODIS Rapid Response Team During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean on March 20 at 10:45 UTC (6:45 a.m. EDT) and captured the eclipse’s shadow over the clouds in the Arctic Ocean.
Terra launched 25 years ago on Dec. 18, 1999. Approximately the size of a small school bus, the Terra satellite carries five instruments that take coincident measurements of the Earth system: Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Clouds and Earth’s Radiant Energy System (CERES), Multi-angle Imaging Spectroradiometer (MISR), Measurements of Pollution in the Troposphere (MOPITT), and Moderate Resolution Imaging Spectroradiometer (MODIS).
On Nov. 28, 2024, one of Terra’s power-transmitting shunt units failed. A response team reviewed Terra’s status and discussed potential impacts and options. Consequently, the team placed ASTER into Safe Mode. As a result, ASTER data are not currently being collected. All other instruments continue uninterrupted.

Under NASA’s HQ Office of the Chief Engineer, Terry Hill the Digital Engineering Program Manager, recently signed a Space Act Agreement with Northrop Grumman Space Sector to explore digital engineering approaches to sharing information between industry partners and NASA. This collaboration aims to support NASA’s mission by advancing engineering practices to reduce the time from concept to flight. By leveraging digital engineering tools, this collaboration could lead to improved design, testing, and simulation processes, It could also help improve how the government and industry write contracts, making it easier and more efficient for them to share information. This would help both sides work together better, handle more complicated missions, and speed up the development of new space technologies.
This collaboration between NASA and Northrop Grumman brings exciting possibilities for the future of space exploration. By embracing digital engineering, both organizations are working toward more efficient, cost-effective missions and solutions to greater challenges.
