Both the Voyager 1 and 2 spacecraft are healthy and they continue to collect fields and particles data in their quests to detect the heliopause, the outer edge of the sun's energy influence.
In addition, both spacecraft are using the ultraviolet spectrometers to look back at our Sun and study solar activities. Voyager 2 will use its ultraviolet spectrometer and the planetary radio astronomy experiment to observe the impact of comet Shoemaker-Levy 9 with Jupiter later this month.
As of July 1, Voyager 1 was 8.3 billion kilometers (5.1
billion miles) from Earth and Voyager 2 was 6.4 billion
kilometers (3.9 billion miles) from Earth. Voyager 1 is
traveling at an average heliocentric velocity of 39,200 miles per
hour and Voyager 2 is traveling at 36,200 miles per hour.
