Galileo Continues to Survey Jovian Magnetosphere as It Heads Toward Its December 28 Encounter

Galileo's Fields and Particles instruments continue to survey the Jovian magnetosphere this week as the spacecraft slowly makes its way toward the heart of the Jupiter system and its next encounter on December 28, 2000.

The Fields and Particles instruments are in the midst of a 100-day continuous survey that starts in the solar wind, continues through the Jovian magnetosphere, and proceeds back out into the solar wind. The data acquired during the survey are transmitted to Earth in real time when antennas of NASA's Deep Space Network are listening to Galileo's radio transmissions. When antennas are being used by other space missions, the spacecraft is recording these data on its onboard tape recorder for playback to Earth at a later time. Galileo's tape recorder is used 12 times this week.

The Fields and Particles instruments are the Dust Detector, Energetic Particle Detector, Heavy Ion Counter, Magnetometer, Plasma Detector, and Plasma Wave instrument. The survey they are conducting is part of a joint venture with the Cassini spacecraft, which is now approaching Jupiter. Cassini will fly past Jupiter and proceed to Saturn, where it is scheduled to arrive in 2004. Using data from both spacecraft, scientists will be able to see how changes in the solar wind can influence conditions in the interior of the magnetosphere.
