Ralph P. Harvey

Most of my research involves the geochemical study of planetary materials (meteorites, mars rocks, and micrometeorites), but I am very broadly trained and my interests are diverse. Below is a list of research I'm involved in. The most active ones right now are in italics. - *Experimental studies of interactions between the crust and atmosphere of Venus (with NASA Glenn)* - *The recovery of meteorites and micrometeorites from Antarctica* - *The DAVID mission to fly by a very small asteroid and study its evolutionary history (with NASA Glenn)* - *The adhesive and other physical properties of asteroidal regolith (with NASA Glenn)* - Experiments simulating interactions between brines and crustal rocks on Mars and large asteroids - *Development of a scanning electron microscope for deployment on Mars (with NASA Marshall)* - Studies of the mineralogy and geochemistry of meteorites, with a focus on Martian meteorites and micrometeorites - The recent history of polar icesheets, as revealed by ice movement networks, ice chemistry and cosmogenic radionuclide studies - Weathering and associated mineralogical alteration mechanisms on Earth, Venus and Mars - The geological history of Mars, with a focus on volcanism, rock/ice/water interactions, and possible source regions for the Martian meteorites - Exploring the geochemical and climatological limits on biological activity in cryogenic settings - Future human and robotic exploration of Mars and the asteroids.
