Dr. Craven received the B. S. degree from the University of Alabama in Tuscaloosa in 1967. He has received an M.S. and Ph. D. degree from the University of Alabama in Huntsville, earning the Ph. D. Degree in December of 1993.
After joining the Magnetospheric Branch in the Space Science Laboratory, Mr. Craven participated in the analysis of data from the Light Ion Mass Spectrometer on the SCATHA satellite, helping to provide temperature and density characteristics for the low energy ions in the plasmasphere and plasma trough. He has been involved in the analysis of the Retarding Ion Mass Spectrometer (RIMS) data on the Dynamics Explorer 1 satellite and also with statistical studies using the data from RIMS. He has conducted a survey of the temperatures obtained from DE1 / RIMS, characterizing their behavior based on solar and geomagnetic activity, and completed an extensive survey of N+ in the inner magnetosphere based on the DE1 / RIMS and AE data. He has participated extensively in developing methods for computerizing the reduction of the large database from RIMS to temperature and density values for each ion. He is participating in the development of an empirical model of the total density of plasmaspheric plasma and in studies of the plasmaspheric ion and electron temperature. He has, in the past, had a variety of responsibilities concerning collection and analysis of data for overall models. His experience prior to joining the Magnetospheric Branch in this respect involved a photographic based study of contamination on Apollo 15 and a study of comet Kohoutek.
Dr. Craven served as the Assistant Mission Scientist on Spacelab 1 which flew in 1983 and in the same capacity on the very successful ATLAS 1 mission which was completed in April, 1992.
