Juno probes Jupiter's interior and exosphere

Juno has been in orbit about Jupiter for 18 months, one quarter of the way into an ambitious mission to map Jupiter’s magnetic and gravitational potential fields, probe its deep atmosphere, and study its polar magnetosphere and powerful auroras. Observations acquired during eight of Juno’s first nine orbits provide the first truly global coverage of Jupiter and its environment. Juno reveals a magnetic field unlike anything previously imagined; an interior stirred to great depths by zonal winds; and auroral complexity that defies expectations. We present a sampling of early science results from Juno’s comprehensive science instrument suite. 




Since joining NASA, Jack Connerney has participated in magnetic field investigations and studies of every magnetized planet in the solar system, from Mercury and Mars to Jupiter, Saturn, Uranus, and Neptune. He developed techniques for measurement, analysis, and modeling of planetary magnetic fields using both in-situ and remote observations. His more than 200 scientific publications span several disciplines, including planetary magnetic fields, geophysical inverse theory, ionospheres, aurorae, and the electrodynamic interaction of satellites and ring systems with a planetary magnetic field. He leads the magnetometer group at NASA’s Goddard Space Flight Center.

Jack Connerney is the Deputy Principal Investigator for Juno, the New Frontier Mission to Jupiter. He leads the magnetic field investigations on Juno and MAVEN (in orbit about Mars) and participated as Co-Investigator on the Voyager 1 and 2, Tethered Satellite, and Mars Observer and Mars Global Surveyor magnetometer investigations.
