including the highly successful IMP series of 10 spacecraft launched from 1963 to 1973. IMP-8 is still operating successfully after 22 years in orbit. His investigations of the structure and dynamics of the interplanetary magnetic field (from 0.3 to 60 AU and beyond) definitively established the present-day understanding of the magnetoplasma structure of interplanetary space. Equally important have been the study and discovery of magnetic fields and magnetospheres at the planets Mercury, Jupiter, Saturn, Uranus, and Neptune and their accurate quantitative descriptions. Dr. Ness pioneered in studies of solar wind interaction with the geomagnetosphere and planetary magnetospheres. He is currently principal investigator on the Voyager Magnetic Field experiment and co-investigator on the U.S. Mars Global Surveyor and Advanced Composition Explorer missions. He became president of the Bartol Research Institute on January 1, 1987. He has been involved in cooperative research with colleagues from the Federal Republic of Germany, Italy, and the former USSR. A member of the National Academy of Sciences and Accademia dei Lincei, he is also a fellow of the American Geophysical Union and the International Academy of Astronautics. He was a Sigma Xi National Lecturer from 1989 to 1991.
THOMAS F. TASCIONE is vice president, Space and Environmental Systems Operations, Sterling Software (1996 to the present); in this position he is leading an effort to start a commercial space weather forecasting center. He received his PhD in space physics from Rice University (1982). His prior professional experience was with the Department of Defense (1972-1993). As Deputy Director of the Air Force Weather Service, Dr. Tascione served as the focal point on all space weather activities. He co-chaired the interagency committee that initiated and developed the National Space Weather Program (NSWP) and was instrumental in the development of the NSWP strategic and implementation plans. During his Air Force career, Dr. Tascione served as the lead space weather forecaster and architect of the Air Force space weather forecast models program.
