The propose of this team is to confront some of the most pressing challenges that we are facing in the heliosheath (HS) and its outer boundaries as observed by Voyager 1 (V1) and 2 (V2). Our goal is to make critically needed progress on challenging but tractable questions that have arisen over the last several years, and advance key aspects of our understanding of the HS. Following the crossing of the heliopause (HP) by Voyager 1 in late 2012 (although not all agree with this statement-predicting that Voyager 1 will cross the HP in 2016), several fundamental holes in our understanding of the HS became clear (not all members of our team agree that this was the HP crossing, but we adopt this view for simplicity). Making significant progress on the most important questions will prepare us for the crossing of the HP by Voyager 2, still within the HS. Within the main questions tackled are:
1. The puzzling orientation of the interstellar magnetic field ahead of the heliopause.
2. The unexpectedly narrow width of the heliosheath.
3. The complicated particle and field structure near the heliopause.
The header figure and the above figure show the overall image of the heliosphere as well as an overview of the energetic particle observations at V1, 2012.35 to 2013.40 showing the contrary behavior of GCRs and lower-energy particles (from Krimigis et al. 2013).
