Human Digital Twin Platform (HDTP) is a virtual counterpart of a personrsquo;s biological and physiological presence in the Metaverse. HDTP will enable the creation of a custom, real-time 3D, photo-realistic avatar and combines it with an always-on, real-time physiological monitoring system that uses COTS wearable biosensors. These biosensors measure and monitor the userrsquo;s vitals, sleep, and ...

Design of reentry vehicles is driven by aeroheating concerns at elevated flow enthalpies. As such, accurate simulation of hypersonic flow phenomena such as detached bow shocks is of critical importance for reducing conservatism in design and unlocking improved performance. Adaptive mesh refinement (AMR) is an enabling technology to efficiently reduce numerical error in hypersonic reacting flow sim ...

An unsteady, feature-based grid adaptation approach is proposed that addresses the main drawbacks of the current state of the art, namely, the lack of error control of the unsteady derivative terms, the lack of continuous representation of the mesh metric sensors in time, and the lack of adaptation of the mesh velocity to the dynamic flow features in hypersonic flows, e.g., shocks, mixing layers, ...

We are proposing the research and development of a calibration-free sensing suite for contaminant detection and conversion efficacy analysis of emerging in-situ resource utilization (ISRU) propellant production technologies for future Martian missions. The Phase I effort will focus on developing a spectroscopic strategy to (1) detect select trace-level (ppm) contaminants (CO, HCl) in fuel and oxid ...

Cislune has proposed the development of an innovative solution to make lunar landing pads more resilient and reduce ejecta and improve lander performance. Landing pads undergo erosion, spallation, and potential burn-through and catastrophic failure when subjected to plumes. Cislune has innovated a robotic launch deflector cone made from lunar resources that can be positioned autonomously under the ...

Cislune and UCF propose to develop anti-slip algorithms to identify wheel slip autonomously to avoid getting stuck, a potentially mission ending danger that if you can lower the risk of, allows faster traverse and more productive missions. The algorithms will also be optimized to create continuous recompaction of lunar roads and landing zones, avoiding the wheel-churn of driving.Using some of the ...

This Phase I SBIR will lead to the development of a bandwidth tailored pump source for high purity photon pair generation. Spontaneous parametric down conversion can be used to generate high purity photon pairs at wavelengths of interest to NASA and the broader scientific community. However, these sources are highly dependent on pulsed pump laser parameters. Traditional pulsed laser sources are la ...

In response to NASArsquo;s requirements for improved measurement and analysis techniques for propulsion system performance characteristics for rocket propulsion systems, IFOS is developing a scalable, wirelessly networked, photonic instrumentation solution for measurement of flight-induced flexure. IFOSrsquo; solution leverages the latest advances in multicore fibers (MCF) and highly confined Bril ...

High-accuracy metrology is vitally important in manufacturing and optimally using ultra-high-quality free-form mirrors designed, for example, for space X-ray telescopes to manipulate X-ray light with nanometer-scale wavelengths. Due to the shorter wavelength, requirements on the surface figure (shape) and finish (roughness) of X-ray mirrors are many orders of magnitude more stringent than for visi ...

To address the NASA need for robust, high-fidelity, quantitative, there-dimensional (3D) nondestructive evaluation (NDE) of ablative materials and other spacecraft structures, Albireo Technologies LLC (ATC) proposes to develop a newnbsp;Time-Synchronized X-Ray Compton Tomography (TESERACT). TESERACTnbsp;nbsp;technology is a powerful extension of the Compton imaging tomography (CIT) NDE technique, ...
