Galileo

The Space Physics Center under the leadership of the Principal Investigator of the Galileo magnetic field investigation, Professor Margaret Kivelson, was responsible for the fabrication, testing and operation of the Galileo magnetometer. The instrument heralded a new generation of micro-processor controlled devices which derived their lineage from earlier UCLA experiments on board the PVO and the ISEE-1 and 2 spacecraft. The Galileo experiment consists of two ring core flux gate magnetometers (called inboard and outboard magnetometers) which through gradiometry can determine the effect of the spacecraft fields on the measurements. The two magnetometers had three different measurement ranges (32 nT, 512 nT and 16, 000 nT) and were built to withstand the high radiation of the Jovian magnetosphere. The experiment collected a wealth of data from the interplanetary space, Venus, the asteroids Gaspra and Ida and the two Earth fly-bys and operated successfully until the end of mission when Galileo was commanded to enter the jovian atmosphere.
