John Batchelor and I welcomed Dr. Jared Espley, the program scientist for JUNO at NASA HQ.  During our double segment, we discussed the first photos coming back from JUNO, what they show, plus our guest of honor sent us audio waves of the sounds of Jupiter.  You can listen to these sounds below (note that they are described during the segment).  The descriptions have been furnished by our guest. 

1.  The first clip is from our approach toward Jupiter from several weeks ago (before we went into orbit). We crossed through the shock wave created by Jupiter's magnetic field as it interacts with the solar wind.

2.  The second one is more recent - it's from our first close encounter with Jupiter's poles. The sounds are from the radio waves created by the energetic particles that create Jupiter's aurora.

In addition to the sounds of Jupiter which Dr. Espley described in detail, John played the theme music from the science fiction classic Forbidden Planet.  Do you notice the similarities?

As for what was in the early pictures, we talked about the absence of the latitude bands we are used to seeing on Jupiter.  We talked about the orbit of JUNO and how it will change in the near future.  Another topic was the solar power for the JUNO satellite and the actual solar arrays, plus their rate of degradation due to the high radiation environment.  Lots was said about the electromagnetic waves which were converted to audio waves(sound waves) as space is a vacuum and there is no sound.  Jared then described the Bow Shot clip, talked about Earth also having a Bow Shot clip, then he talked about the sound of the solar wind which is extremely fast moving on Jupiter.  Jared was asked about the mission to determine what kind of core Jupiter has, the JUNO instrument package, and finding out what Jupiter is actually made of  - one of the scientific mysteries JUNO hopes to resolve.  Jared said that at this time it takes 48 minutes to communicate with JUNO due to its distance from Earth.  Before our double segment ended, we talked about having built JUNO for unknowns that may be discovered and the risks for the spacecraft in designing for unknown events, an unknown environment, and more.
