Brief Bio


Since joining NASA’s Goddard Space Flight Center in 1979, Jack Connerney has participated in magnetic field investigations of every magnetized planet in the solar system, from Mercury, Earth and Mars to Jupiter, Saturn, Uranus, and Neptune. He developed novel techniques for measurement, analysis, and modeling of planetary magnetic fields using both in-situ and remote observations. His >200 scientific publications span several disciplines, including planetary magnetic fields, crustal magnetism, geophysical inverse theory, ionospheres, aurorae, and the electrodynamic interaction of satellites and ring systems with a planetary magnetic field. He was Co-Investigator on the Voyager 1&2, Tethered Satellite, Mars Observer and Mars Global Surveyor magnetic field investigations, MAG lead on Maven and Juno Magnetic Field Investigations.

Now with the Space Research Corporation (at GSFC), Jack continues as Deputy Principal Investigator for Juno, the New Frontier Mission to Jupiter (PI: S. Bolton/SWRI) and leads the magnetic field investigation on Juno. 

Dr. Connerney received a B.S. (1972) and Ph.D. (1979) in Engineering Physics at Cornell University and began his Goddard career as a NAS/NRC postdoctoral fellow, accumulating 35+ years of experience in space systems, space flight hardware, and planetary research. He is a fellow of the American Geophysical Union (2009), recipient of the NASA Medal for Exceptional Science Achievement (1986), the John C. Lindsay Memorial Award for Space Science (1994), the NASA Medal for Exceptional Achievement (1998), and the Doctor Technices Honoris Causa from the Technical University of Denmark (2015).
