We propose a framework leveraging machine learning to enable the development of Earth System Digital Twins (ESDTs) through a machine-learned (ML) stochastic bin microphysics (SBM) emulator. To achieve the fast observational feedback required by an ESDT, we plan to first implement a conditional variational auto-encoder/decoder (cVAE/D) model as a radar observation parameter (ROP) mapper that maps t ...

Compact chip-scale nano-NMR sensors to measure D/H ratio in water of outer planets based on atomistic defects in semiconductors will have orders of magnitude improved sensitivity compared to classical NMR instruments.nbsp;nbsp;Our sensors will be able to detect D/H ratio in reduced sample size as the magnetic fields generated by small samples are too small for traditional sensors to detect. Micros ...

In this Phase I proposal, Remcom proposes a complete, end-to-end modeling and simulation solution for predicting wireless propagation and network coverage for lunar scenarios. Our solution builds on mature, existing capabilities previously developed for the wireless industry and the U.S. government, specifically enhanced to include 4G and 5G technologies. Under this effort, we will perform researc ...

Improved thermospheric density forecasts are a critical need identified by the Space Weather Operations, Research, and Mitigation (SWORM) Working Group, a Federal interagency coordinating body [National Space Weather Strategy and Action Plan, 2019]. This work will improve thermospheric density prediction by reducing forecast error up to 65% during large geomagnetic storms. We will validate two rep ...

The design and development of a compact, rugged, cost-scalable optical diagnostic for measuring temperatures, species concentrations, and velocities to advance research vital to enabling the next generation of high-speed air platforms is proposed.nbsp;The sensor design overcomes many challenges associated with making measurements in the extreme environments of hypersonic and reactive flows. The sy ...

Optomecrsquo;s proposed innovation is a direct-write additive manufacturing process, creating 25um electrical interconnects that can accommodate 3D steps and are terminated in a wire bond pad.nbsp; These printed interconnects will minimize packaging space by replacing traditional wire bonds with conformal fan-out electrodes.nbsp; This additive manufacturing proposal ldquo;is a science enabling tec ...

Dexterous robotic manipulation is an essential technology for establishing a permanent, sustainable space infrastructure (NASA#39;s Moon-to-Mars objectives). Given the massive cost of having humans in space, sustained human presence and exploration throughout the solar system, ironically, requires capable non-human labor resources. Crew time is a highly limited resource and robotic operations are ...

The U.S. hypersonic ground- and flight-test communities require advanced Instrumentation systems that can inform a vehicle structural health monitoring (SHM) system operating in extreme hypersonic environments, with the long-term goal of deployment on an operational hypersonic aircraft allowing maintenance requirements and life predictions to be based on the vehiclersquo;s/systemrsquo;s actual fli ...

The vision of NASArsquo;s Artemis program is to lead humanity forward in the exploration of the Moon which will prepare us for the exploration of Mars. Paramount to the success of this program is the ability to provide reliable electric power throughout the lunar day and night. The terrestrial grid is primarily composed of AC systems to accommodate legacy grid infrastructure. However, DC microgrid ...

The air transportation system is on the verge of drastic change.nbsp; Enabled by technological advances in areas including electric propulsion, computational capabilities, and machine learning, emerging vehicles have the potential to drastically lower transportation costs.nbsp; Vertical takeoff and landing (VTOL) capabilities are expanding operational flexibility, and will allow vehicles to takeof ...
