3.2.1 Science and Observation Objectives: The magnetospheric scientific objectives are given in the Galileo Orbiter Science Requirements Document as: Characterize the absolute energy spectra, composition, and angular distribution of energetic charged particles as a function of position (to 150 Rj) and time, Characterize the vector magnetic fields as a function of position (to 150 Rj) and time, Characterize the absolute energy spectra, composition, and angular distribution of plasma, including plasma wave phenomena, as a function of position (to 150 Rj) and time, Investigate satellite-magnetosphere interactions. In order to respond to the challenge to maximize the fulfillment of these broad objectives within the confines of the greatly reduced telemetry rate with the Low Gain Antenna (LGA) mission, the Magnetospheric Working Group (MWG) derived a more specific list of prioritized observations objectives as follows. 1.) Magnetospheric Survey requiring continuous real-time data throughout the tour. 2.) Tail Petal observations which require recording of fields-and-particles data during periods when the range to Jupiter is greater than 100Rj 3.) Satellite Wake interactions with the magnetosphere, requiring recording of fields-and-particles data during satellite closest approaches. 4.) Satellite Flux Tube interactions with the magnetosphere, requiring recording of fields-and-particles data during satellite closest approaches. 5.) Satellite Alfven Wings, & other interactions with the magnetosphere, requiring recording of fields-and-particles data during satellite closest approaches. 6.) Remote observations of the Io torus with EUV/UVS during each orbit. 7.) Simultaneous in situ fields-and-particles observations and remote observations of the Jovian Aurora with NIMS and UVS 8.) Crossings of satellite L-shells requiring real-time and recorded fields-and-particles data. 9.) Radio occultations (TBD) by the satellites 10.) High resolution plasma sheet observations requiring the recording of fields-and-particles data. 11.) High resolution observations of latitudinal variations of magnetospheric phenomena (near the plasma sheet) requiring the recording of fields-and-particles data near the apoapses of selected orbits. 12.) High resolution equatorial crossing observations requiring the recording of fields-and-particles data during selected orbits. 13.) Kilometric radiation observations (TBD) at greated than 60 Rj that require the recording of PWS data at selected periods during each orbit. last updated: Sept 29, 1995These observation descriptions are indicative, with others, of those carried out during the mission.
