DOY 2001/232-238

Another very quiet week of cruise activities is in store for the Galileo spacecraft. On Thursday, a test of the on-board gyroscopes is conducted. The electronic circuits governing these gyros have shown sensitivity to the intense radiation experienced as we fly close to Jupiter. Periodically running these tests allows us to determine if the software scale factors that are applied to the gyro measurements need to be updated to correctly interpret the information. The last such test was performed on August 7, just after the flyby, and this test will show to what extent the circuits have recovered from the radiation effects in the intervening two weeks.

Continued playback of the data stored on the tape recorder during the Io flyby occupies the Galileo science community this week. Data from the Solid State Imaging camera, the Near Infrared Mapping Spectrometer, and the instruments that measure the electromagnetic fields and particles of the Jupiter environment are on tap. This week's playback should include the measurements taken just as Galileo reached its closest approach to Io, at a distance of 200 kilometers (124 miles), including views of the Isum, Tvashtar, and Prometheus volcanoes.
