USING SATELLITE CONSTELLATIONS FOR GEODESY AND TIME DEPENDENT GRAVITY (TIDES ON EUROPA)

Dr. William B. Moore, Hampton University
May 16, 2014, 10:00 am, NASA Langley, Bldg 1250, Rm 116

Abstract:
Satellite-satellite tracking has proved extremely effective at monitoring time-dependent gravity at the Earth (GRACE) and Moon (GRAIL), and a similar approach would be useful anywhere there are strong time-dependent (tidal, atmospheric, or oceanographic) signals. I will discuss the use of such techniques at Europa for determining tidal amplitude and ocean currents. An implementation of a multi-purpose laser altimeter/sub-satellite ranging system will be described.

Background:
Dr. Moore earned his Ph.D. and M.S. in Geophysics & Space Physics at the UNIVERSITY OF CALIFORNIA, Los Angeles, CA. He has served on a number of high-level committees for determining and evaluating research policy in the United States. As part of the steering committee for the Outer Planets Assessment Group, the National Academy of Sciences decadal review of solar system exploration, and the science definition teams for the Jupiter Icy Moons Orbiter and Europa Flagship Explorer. Dr. Moore has also helped to set national science priorities for future exploration of the solar system. He has participated in a number of successful missions to explore other planets (Magellan, Galileo), and looks forward to being a part of future NASA exploration of the Solar system. Dr. Moore joined the Atmospheric and Planetary Sciences staff as an Associate Professor in Spring 2010.
