NASA’s uncrewed Artemis I mission launched from KSC on November 16, 2022. After a successful mission that included orbiting the Moon, the Orion spacecraft returned to Earth splashing down in the Pacific Ocean on December 11, 2022. While the spacecraft made a safe return to Earth, postflight inspection of Orion’s thermal protection indicated that the base heatshield did not perform as expected. The heatshield is composed of Avcoat, an ablative material designed to protect the crew module during the nearly 5000ºF temperatures experienced during atmospheric entry upon return from the Moon. Specifically, inspection revealed more than 100 locations where the charred Avcoat material chipped away from the heatshield.
The NESC formed a team of subject matter experts from across and outside of the Agency to assist the Orion Program team in the overall investigation. NESC team members are supporting or leading efforts in multi-physics analysis, material testing, fault tree and root cause analysis, aeroscience review, analysis peer review, nondestructive evaluation (NDE), as well as investigation of alternative heatshield concepts.
The NESC works closely with the Artemis I Char Loss Team to ensure the observed material loss is thoroughly understood so that decisions may be made regarding use for upcoming crewed missions. To date, NESC contributions have included pathfinding NDE techniques for postflight heatshield inspection, investigation of key Avcoat material properties and behavior, and providing key inputs to the fault tree development and disposition to guide a thorough investigation of possible causes.

Credit: NASA NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Southwest Research Institute of San Antonio to build the Next-Generation Space Weather Magnetometer for the Lagrange 1 Series project as a part of NOAA’s Space Weather Next program.
This cost-plus-fixed-fee contract is valued at approximately $26.1 million and includes the development of two magnetometer instruments. The anticipated period of performance is from December 2024 through January 2034. The work will take place at the awardee’s facility in San Antonio, NASA’s Goddard Space Flight Center in Maryland, and Kennedy Space Center in Florida.
The contract scope includes design, analysis, development, fabrication, integration, test, verification, and evaluation of the magnetometer instruments; launch support; supply and maintenance of ground support equipment; and support of post-launch mission operations at the NOAA Satellite Operations Facility.
These instruments will measure the interplanetary magnetic field carried by the solar wind. The instruments provide critical data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings and alerts that help mitigate space weather impacts, including electric power outages and interruption to communications and navigation systems.
NASA and NOAA oversee the development, launch, testing, and operation of all the satellites in the Lagrange 1 Series project. NOAA is the program owner providing the requirements and funding along with managing the program, operations, data products, and dissemination to users. NASA and its commercial partners develop and build the instruments, spacecraft, and provide launch services on behalf of NOAA.

Credit: NASA NASA has selected Nova Space Solutions, LLC of Anchorage, Alaska, to provide operations, services, maintenance, and infrastructure support for NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and NASA’s Michoud Assembly Facility in New Orleans.
The Combined Operations, Services, Maintenance, and Infrastructure Contract is a cost-plus-incentive-fee, firm-fixed-price, and indefinite-delivery/indefinite-quantity contract that has a value of approximately $822.7 million. The performance period begins July 1, 2025, and extends eight years and three months, with a 15-month base period, followed by a one-year option period and three two-year option periods.
Under the contract, Nova Space Solutions will be responsible for contract management, logistics, safety, health and environmental compliance, engineering and manufacturing support services, site services, facility operations and maintenance services, and environmental services and program management.
NASA’s Stennis Space Center is the nation’s largest propulsion test site, with infrastructure to support projects ranging from component and subscale testing to large engine hot fires. Researchers from NASA, other government agencies, and private industry use NASA Stennis test facilities for technology and propulsion research and developmental projects. NASA’s Michoud Assembly Facility, managed by the agency’s Marshall Flight Center in Huntsville, Alabama, is the nation’s premier site for manufacturing and assembly of large-scale space structures and systems.

1 Min Read 2024 NESC Technical Update
Annual Report of NESC Technical Activities
On behalf of the NASA Engineering and Safety Center (NESC), I am pleased to provide you with the 2024 NESC Technical Update. This annual report summarizes the technical work, engineering advancements, and knowledge capture efforts we made in FY24. With support provided by members of our NASA community from across the centers, we focused our efforts on performing value-added independent testing, analysis, and assessments of NASA’s high-risk projects to ensure safety and mission success.
This report contains summaries of technical assessments requested by our stakeholders and the technical bulletins and innovative techniques that resulted from that assessment work. Several of the NASA Technical Fellows provide summaries of accomplishments in their respective disciplines, and expertise drawn from across the Agency is featured on the Center Pages.
We appreciate the opportunity to share our progress and highlight the accomplishments of our technically and culturally diverse, multidisciplinary, multigenerational teams. All NESC knowledge products are available at nasa.gov/nesc. As always, we value your feedback and engagement. Thank you for your continuing support of the NESC.
