The Johns Hopkins University was awarded a $203,902.74 grant from the National Aeronautics and Space Administration (NASA) to develop a time-dependent simulation model of the inner heliosphere and solar wind environment. The project aims to improve scientific understanding and space weather forecasting by incorporating data-assimilative photospheric magnetic field maps into a magnetohydrodynamic (MHD) model. Key tasks include integrating time-varying inputs from the ADAPT-WSA model, developing...
This is a $141,749.84 grant awarded by the National Aeronautics and Space Administration (NASA) to the University of Maryland, College Park (UMD) to develop a state-of-the-art model for forecasting the dynamics of the Earth's radiation belt and energetic plasma environment. The project aims to improve the ability to model and predict the ultra-low frequency (ULF) wave power and resulting radial diffusion coefficients, which are key processes controlling the acceleration, transport, and loss of...
This is a $389,355.78 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private research university in Baltimore, Maryland. The grant is for a research project titled "Dipolarization in the Inner Magnetosphere" that aims to investigate the characteristics of dipolarization, a fundamental process in magnetospheric physics, using data from the Van Allen Probes and THEMIS satellite missions. The project has three main research...
The National Aeronautics and Space Administration awarded a $1.3 million grant to The Johns Hopkins University to support research understanding and predicting geospace storm dynamics as part of the agency's Heliophysics program. The three-year award will fund research at the prime contractor's facilities in Baltimore, Maryland, beginning March 2020. No subcontractors or set-aside designations were identified.

This is a $524,856.84 grant awarded by the National Aeronautics and Space Administration (NASA) to Trustees of Dartmouth College to support research on the role of electromagnetic ion cyclotron (EMIC) waves in precipitating relativistic electrons from the Earth's radiation belts. The goal is to expand understanding of radiation belt particle dynamics and quantify the effectiveness of EMIC waves in causing electron precipitation over a broad energy range. This work addresses one of the high-level...
This $490,276.93 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University aims to improve predictions and modeling of the variability of relativistic electrons in the Earth's outer radiation belt. The project will develop a physics-based model with data-flexible ingestion capability to provide more accurate forecasts of the energetic particle and plasma conditions encountered by spacecraft within Earth's magnetosphere. This will help mitigate the risks posed by radiation belt electrons, which can accumulate charge and lead to electrostatic discharge that disrupts and damages spacecraft operations. The research will involve coupling magnetohydrodynamic and ring current models to study mesoscale electrodynamics in the inner magnetosphere. The resulting modeling tools and data products will be made available through NASA's Community Coordinated Modeling Center to support the broader research and operational community. This grant does not have a set-aside designation.
