6.3 Closest Approach Results

 

The closest approach region of the G2 encounter encompasses the time interval between 18:55:51 to 19:05:00 UT. Figures 6.54 and 6.55 show three field line tracings for three typical adsorption features observed by Galileo for model M1 and model M2, respectively. Of course, there are many more features present in the closest approach region; these embody the characteristics of them all. Each rate profile presents a loss cone adsorption for the ions and electrons, with the electrons also exhibiting loss cones in the anti-moon direction. Not all energy channels for these two features are presented here in Chapter 6. Table 6.10 gives information and some details on the plots not shown here; they are included in Appendix C.

QUICK FACTS

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.
