The research focuses on four main aspects of...
This $192,613.97 federal grant was awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to conduct research on the history and composition of explosive volcanic deposits on the planet Mercury. The research aims to determine when these deposits formed and analyze variations in the volatile gas fraction and magma composition across the deposits. It will leverage data from the MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER)...
This is a $352,184.57 grant award from the National Aeronautics and Space Administration (NASA) to Trustees of Boston University, a private university in Boston, Massachusetts. The grant supports research to better understand the physical processes governing the generation of Mercury's alkali exosphere. The proposed work involves analyzing ground-based data and interconnecting magnetosphere, surface, and atmospheric models to address key science questions about the relative contributions of...
This federal contract award to Trustees of Boston University, a private university located in Boston, Massachusetts, is for NASA to conduct ground-based observations of Mercury's exosphere. The primary goals are to: 1) Continue ongoing measurements of sodium, calcium, and potassium, and 2) Observe less abundant species such as aluminum, iron, manganese, and calcium ion to expand upon the observations made by the MESSENGER mission. This $392,043.66 grant is intended to provide long-term...
This is a $319,012.72 grant awarded by the Shared Services Center, a civilian U.S. government agency, to The Johns Hopkins University on June 1, 2016. The objective of this grant is to develop a comprehensive model of Mercury's magnetospheric magnetic field to better understand the interactions between Mercury's interior, surface, and magnetosphere, which is relevant to the Solar System Roadmap's goal of determining how the solar system evolved to its current state. The grant supports three main...
This is a $134,694.71 grant awarded by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University, a private non-profit university, to conduct research related to understanding Mercury's internally generated magnetic field. The grant does not have a set-aside designation. The research aims to address limitations in current understanding due to the impact of external signals in Mercury's active magnetic environment. This award is not associated with a larger...
This federal contract award, valued at $207,287.04, was granted by the National Aeronautics and Space Administration (NASA) to The Johns Hopkins University to conduct research on characterizing the geochemical terranes of the planet Mercury. The research aims to provide insights into the processes that dominated Mercury's crustal evolution, including the formation of the primary crust, volcanic resurfacing, and impact modification. The contract leverages data from the MESSENGER (MErcury Surface,...
This was a $179,894.38 grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to the University of Maryland, Baltimore County (UMBC) on July 28, 2017. The grant funded research to analyze tracking data from the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry and Ranging) spacecraft mission, which was the first to orbit Mercury. The goal was to develop high-resolution gravity field models and estimate local variations in crustal density....
This is a grant awarded by the National Aeronautics and Space Administration (NASA) Shared Services Center to The Johns Hopkins University, a private non-profit research university, to conduct a targeted study of processes in Mercury's exosphere. The three-year, $331,585.66 grant has the objectives of: 1) using ultraviolet and visible spectrometer (UVVS) data and a Monte Carlo code to determine the overall "background" structure of the sodium (Na), magnesium (Mg), and calcium (Ca) exospheres; 2) investigating the short-term temporal and spatial variations of the Na, Mg, and Ca exospheres; and 3) using the Monte Carlo code to explore the parameter space of the source and loss processes that generate Mercury's complex exosphere. The grant leverages data from NASA's MESSENGER mission to advance understanding of the processes behind Mercury's exosphere and provide insights into exospheres of other airless solar system bodies and rocky exoplanets. There is no set-aside designation for this grant award.
