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.

Director, NASA Engineering and Safety Center

When/Where
August 27-28, 2024
NASA Jet Propulsion Laboratory in Pasadena, CA
Who may attend?
Invited participants from the NASA Centers, NASA HQ, and the broader community of IR technology developers and stakeholders. All participants must be U.S. Persons – the meeting will be held at the CUI level and presentations may contain ITAR material.
Registration will be available, soon!
Purpose
The purpose of the TIM is to openly discuss and review the current state of IR technology in the 2-1000 µm wavelength range. This workshop is intended to evaluate existing relevant NASA-needed technologies and developments, identify opportunities for investments and collaboration, and formulate agency-level strategies to meet its near- and far- term needs for science and exploration missions. The presentations and contact information list will be captured in a proceedings package that will be available to all attendees and NASA stakeholders.
Background
IR detector technology is critical for NASA’s future missions, many of which require state-of-the-art infrared payloads in support Science Mission Directorate (SMD), Space Technology Mission Directorate (STMD), and Exploration Mission Directorate (EOMD). IR sensors utilized in infrared missions span a wide gamut, including multispectral, polarimetric imaging, point-source detection, scanning dispersive hyperspectral imaging, staring interferometric hyperspectral imaging, and astronomical imaging. Space-qualified IR detectors are a leading item on NASA’s critical technology lists as they are key enablers for many science missions. The objectives and IR sensor needs for future NASA missions are described in the most recent decadal surveys for Earth Science, Planetary Science, Heliophysics, and Astronomy and Astrophysics:
Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space Origins, Worlds, and Life: A Decadal Strategy for Planetary Science and Astrobiology 2023-2032 Solar and Space Physics: A Science for a Technological Society Pathways to Discovery in Astronomy and Astrophysics for the 2020s To promote knowledge sharing among science and engineering practitioners external- and internal-to NASA, the NASA Engineering and Safety Center (NESC) Sensors & Instrumentation Technical Discipline Team (S&I TDT) recently established an IR Detector Community of Practice (IR CoP).

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Launch of the Hypersonic International Flight Research Experimentation Program (HIFiRE) Flight 2 sounding rocket, a joint NASA-Air Force Research Laboratory flight experiment, May 1, 2012.Credit: AFRL Technical Challenges (TCs) are finite-duration research and development endeavors supporting the strategic goals of NASA. The Hypersonic Technology project’s Technical Challenges include estimation of uncertainty for hypersonic research problems and vehicle systems, testing controls for switching engines mid-flight, and researching more efficient fuel combustors for large ramjets, which will be needed by future commercial high-speed planes.
Uncertainty Quantification
This Technical Challenge is complete!
TC-1: System-Level Uncertainty Quantification Methodology Development and Validation: NASA developed and validated a system-level uncertainty propagation methodology to guide uncertainty-informed decision making by identifying fundamental research areas that will reduce the system performance uncertainty.

Turbine-Based Combined Cycle
TC-2: Turbine-Based Combined Cycle Mode Transition Technology Development: The Combined Cycle Mode Transition challenge demonstrates autonomous control and establishes performance/operability assessment methodologies for future reusable hypersonic propulsion systems that use turbine engines at slow speeds while transitioning to scramjets for high-speed operations. This challenge addresses the technology barrier of propulsion system mode transition via ground tests.

Improved Combustor Scaling Laws for Hypersonics
TC-3: Development of Improved Combustor Scaling Laws for Dual-Mode Ramjets: To improve current engine performance and enable engine scale up to fully reusable vehicle scales 100 times larger, NASA will develop and deliver mathematical models and associated validation test data with quantified uncertainty that support the design of high-speed combustors inclusive of green fuels. NASA will demonstrate such capability by reducing the length of the state-of-the-art cavity flameholder by 25 percent (10 percent threshold, 25 percent goal cavity length reduction relative to a state-of-the-art baseline.)
