Jennifer A. Grier
JA Grier (born 1968) is an American planetary science, planetary scientist who works as a senior scientist and senior education and communication specialist at the Planetary Science Institute. Grier's research has focused on the weathering of planets, moons, and asteroids, the age of Ejecta, impact ejecta on the lunar soil, the chemical composition of meteorites, and the existence of water on Mars. They are also active in science education. Education and career Grier completed a PhD in 1999 from the University of Arizona with a dissertation ''Determining the ages of impact events: Multidisciplinary studies using remote sensing and sample analysis techniques'' supervised by Alfred McEwen. They started working for the Planetary Science Institute in 1999. Publications Grier is a coauthor of books including: *''Guide to the Universe: Inner Planets'' (with Andrew S. Rivkin, Greenwood Publishing, 2010) *''Airless Bodies of the Inner Solar System: Understanding the Process Affecting Roc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Planetary Science
Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and the processes of their formation. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, which originally grew from astronomy and Earth science, and now incorporates many disciplines, including planetary geology, cosmochemistry, atmospheric science, physics, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology. Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. Observational research can involve combinations of spac ...
