Juno Waves Detection of Dust Impacts near Jupiter

Abstract:

The Juno spacecraft entered orbit at Jupiter on July 5, 2016. Since then, Juno has orbited Jupiter in high inclination orbits, crossing the ring plane near perijove 21 times. During 20 of the 21 crossings, the Waves instrument detected signals induced by dust impacts. The impact rate profiles show peaks of order 6/s around the ring plane with half width at half max ~2000-3000 km. The polarity ratio of the impact signals didn't follow the areas of the antennas exposed to dust impacts that change due to the rotation of the spacecraft, suggesting Waves detects impacts on the Juno spacecraft and not just on the Waves antennas. The impact rate profile changed during Perijove 19, when the spacecraft rotation axis was tilted to the south, increasing the area of the solar panels exposed to impacts, indicating that the detected impacts were on the spacecraft body.  Grain sizes of order 1 micrometer are estimated, and the differential size distribution has a slope of -5.1.

Notes on zip archive:

There are subdirectories for each figure including a PDF of the figure and one or more text files with the data supporting the figure.  Where the labeling in the text file is not quite complete, we've added a Fign-readme.txt file.

Figures 9 and 10 are in the same directory as the two figures just have more of the same and all the data for both figures is in the same file.
