JPL Fact Sheet


Voyager 2

Voyager and Galileo will be the only two spacecraft actually in view of the nightside impact points for the many comet fragments. Voyager 2, launched in August 1977 and now leaving the solar system after flying by and observing Jupiter, Saturn, Uranus and Neptune, will be some 6 billion kilometers (3.7 billion miles) from Jupiter in mid-July when the events begin. It will use its ultraviolet spectrometer and its planetary radio astronomy instrument to detect and measure emissions stimulated by the comet impacts.
