Those of you tracking the distances here or on 'that other social channel' will have noticed that the _change_ in the reported distance to Voyager 1 has been slowly _decreasing_. How can this be? Is Voyager returning? ...no. This happens near this time of year, every year. You have to remember that these distances are being measured from a moving platform: Earth. Earth's orbital speed is faster than that of either spacecraft, so at certain times of year, Earth will catch up, and the distance decreases for a little while. This means that if you plot out the distance over time, the lines for both Voyager 1 and Voyager 2 wiggle, as in this first diagram.
