I was going through Emily's New Horizons Jupiter Encounter timeline, and I noticed that there are several observation opportunities for the moons Elara (4 obs.) and Himalia (6 obs.). These two are the only non-Galilean moons observed.
I'm just curious, why were these two moons given that much attention? Was it simply orbital dynamics and that no other (non-Galilean) moon was near New Horizons during the Jupiter flyby? It states that at closest point, Elara will be 29 km per pixel and Himalia will be 27 km per pixel. How does this compare with previous missions? I believe Cassini made an observation of Himalia before. |

My relatively naive assumption was that there isn't much else to be looking at a week after closest approach, when the sun is behind Jupiter and most of the moons. Are the earlier observations an investment in making the last ones more valuable? |
