Summary of scientific research
Br Consolmagno entered the Society of Jesus in August 1989. He holds and SB in Earth and Planetary Sciences, Massachusetts Institute of Technology, 1974, an SM in Earth and Planetary Sciences, Massachusetts Institute of Technology, 1975, and a PhD in Planetary Sciences, University of Arizona, 1978.
Dr. Consolmagno studies the nature and evolution of small bodies in the solar system. His work in the 1970s on the moons of the outer solar system predicted many of the features later discovered by the Voyager and Galileo spacecraft, including the first published suggestion of Europan sub–crustal oceans with the possibility of life. Models for the geochemical evolution of lunar basalts and basaltic meteorites eventually led to the identification, on geochemical grounds, of asteroid Vesta as the parent body of the eucrite, diogenite, and howardite meteorites.
His doctoral thesis on the role of electromagnetic forces in chemical fractionations of the early solar system pioneered the field of gravito-electrodynamics, the behavior of dust subjected to both gravitational and electromagnetic forces, and he was the first person to apply this concept to describe the dynamics of Jupiter’s dust ring.
Geophysical research in the late 1980s to mid–1990s included mapping tectonic features on the surfaces of outer planet icy satellites to correlate the orientation of these features with possible internal stresses, and applying electromagnetic theory to the problem of detecting an ocean brine under the ice crust of Europa. He was also part of the world–wide campaigns to observe the impact of Comet Shoemaker–Levy 9 into Jupiter and mutual events during the Saturn ring plane crossing.
Present research is centered on understanding the origin of moons, meteorites, asteroids, and Trans-Neptunian Objects (TNOs). One continuing project is measuring the physical properties of meteorites, with applications to understanding the lithification of meteorites, the structure of their asteroidal parent bodies, and the nature of their terrestrial weathering. He is also involved in telescope observations of asteroid spectra and the broad band colors of the irregular moons of the outer solar system, dormant comets, and TNOs.
