Chapter 4. Magnetic Field Models


The magnetic fields used in the simulation are the topic of this chapter. A basic review on the origins of these models is discussed. By the end of the chapter there will be two magnetic field models for the magnetic field environment in the vicinity of Ganymede for evaluation. The first, labeled here as model 1 (M1), comprises the dipole model proposed by Kivelson et al. [1996], a dipole field intrinsic to Ganymede and a background field of Jupiter based on the O6 model of Connerney [1993] and the hinged magnetodisk model of Khurana [1997]. The second model is one that is constructed from an internal multipole model for Ganymede, the background field of Jupiter as measured by the magnetometer prior to entry into the magnetosphere, and a magnetopause and tail field configuration using the external multipole model formalism of Choe and Beard [1973, 1974]. This second model is labeled throughout this work as model 2 (M2).

Manufacturer: The Galileo Spacecraft was manufactured by the Jet Propulsion Laboratory, Messerschmitt-Bölkow-Blohm, General Electric, and the Hughes Aircraft Company.

Mission Duration: Galileo was planned to have a mission duration of around 8 years, but was kept in operation for 13 years, 11 months, and 3 days, until it was destroyed in a controlled impact with Jupiter on September 21, 2003.

Destination: Galileo's destination was Jupiter and its moons, which it orbitted for 7 years, 9 months, and 13 days.
