The proposed research, which has a period of...
This is a $308,034.22 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University in Baltimore, Maryland. The grant is for a project titled "Storm-Time Magnetosphere: Specification and Prediction Using a Global MHD Model with Empirical Ring Current Pressure" which aims to improve predictive modeling of the geospace environment during geomagnetic storms. The project will extract equilibrium magnetic pressure data from the Tsyganenko...
This is a $744,398.43 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to investigate the accumulation, transport, and energization of oxygen ions (O+) in the plasma sheet and inner magnetosphere. The research aims to address key science questions on how O+ ion properties evolve during geomagnetic storms, how the spatial distribution of O+ ions depends on solar wind conditions and geomagnetic indices, and where the transport of O+ ions...
This is a $331,405.76 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to conduct research on electromagnetic ion cyclotron (EMIC) waves in the Earth's magnetosphere. The research aims to definitively determine the fundamental properties and propagation characteristics of EMIC waves using data from the Magnetospheric Multiscale (MMS) mission, as well as confirm their evolution using observations from other spacecraft. This work is directly...
This is a $124,833 grant awarded by the Shared Services Center of the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private non-profit research university, for a research project focused on analyzing high-speed magnetosheath jets and their insights into particle acceleration, kinetic shock processes, and the interaction between the solar wind and Earth's magnetosphere. The research directly aligns with the goals of the Magnetospheric Multiscale (MMS)...
This is a $427,105.72 grant awarded to The Johns Hopkins University by the National Aeronautics and Space Administration (NASA) for a research project to study the effects of dayside ionospheric conductance on the structure and dynamics of the magnetotail. The primary goal is to identify and evaluate the active role of the dayside ionospheric conductance in the solar wind-magnetosphere-ionosphere coupling. The research will use satellite data analysis and global magnetohydrodynamic modeling to...
This is a $319,554.14 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University (JHU) to study the effects of interplanetary shocks on the Earth's magnetosphere. The study aims to improve understanding of how shock-induced cavity mode oscillations (CMOs) interact with energetic electrons in the magnetosphere. The investigation will leverage data from multiple space weather monitoring satellites, including the Van Allen Probes and Time History of Events and Macroscale Interactions during Substorms (THEMIS) missions, as well as magnetohydrodynamic (MHD) simulations. This research supports NASA's objectives to understand the dynamics and coupling of the Earth's magnetosphere, ionosphere, and atmosphere, as well as the response of relativistic electron populations to variable solar inputs. The contract has no set-aside designation and runs through January 31, 2020.
