AB: The two Voyager spacecraft are exploring the outer heliosphere at a time of decreasing solar activity, decreasing tilt of the heliospheric current sheet, and decreasing solar modulation of galactic cosmic rays. Voyager 1 is observing the effects of these changes on the magnetic field and on cosmic ray intensities deep in the northern heliosheath at >102 AU, while Voyager 2 is making similar observations of the solar wind and energetic particles just upstream of the termination shock at >82 AU in the south. Insights gained from recent observations and theoretical models will be discussed.
