Research Interests (see the Space Physics Home Page )

Space Physicist Mary Hudson, PhD UCLA 1974, is Professor of Physics and served for eight years as Chair of Physics and Astronomy at Dartmouth College. Hudson is currently one of the principal investigators with the NSF-funded Center for Integrated Space Weather Modeling (CISM), where researchers study the weather patterns that originate from a solar eruption, following the energy and mass transfer through the interplanetary medium, all the way to the earth's ionosphere. Current areas of investigation include the evolution of the radiation belts; how the ionized particle outflow known as the solar wind and the magnetic field of the sun interact with the magnetic field of the earth, producing electrical currents in the ionosphere; and the effects of solar cosmic rays on radio communications near the earth's poles. Professor Hudson is also funded by NASA's Supporting Research and Technology program, studying related effects of the Earth's space radiation environment which can affect both astronaut safety and satellite systems. Along with her students and postdoctoral research staff, she is modeling sudden changes in relativistic electron fluxes and solar cosmic rays at and inside the 24-hr orbital period of many communication and navigation satellites, and effects of global oscillations of the Earth's magnetic field, associated with changes in solar wind conditions which have their origins at the sun. She has served as chair of the NSF Geospace Environment Modelling program, and is funded for research in that program on geomagnetic 'storms'.
