. They were launched in 1977 to take advantage of a favorable planetary alignment of the late 1970s. Although they were officially designated to study just Jupiter and Saturn, the two probes were able to continue their mission into the outer solar system. The Voyager Spacecraft each had equipment capable of recording emission signals given off by the planets, their moons and their ring systems. These equipment were designated as

Interractions of the solar wind with planet's magnetosphere, magnetosphere itself, electromagnetic fields, charged particles emissions, charged particle interactions of the planet, its moons, and the solar wind. All this electromagnetic phenomenons can be transformed into electric signals, which can in turn be amplified and used to excite the membrane of a loud speaker ; thus making audible to the human ear the rustling of the cosmos. All these sounds were recorded while the Voyagers were passing near their targets, and assembled without manipulation, using

Voyager 1
Voyager 1 flew by Jupiter on March 5–6, 1979, recording radio emissions during the Io encounter and at closest approach of Jupiter, 349000 km (216,859.1 mi). With a gravity assist via Jupiter, Voyager 1 then went on to Saturn, where it recorded the radio waves emitted by Saturn during its closest approach of 124000 km (77,050.2 mi) on 12 November 1980, and during its outgoing retreat on 14 November. It also managed to achieve a Titan flyby, in which Voyager too did make readings.
Voyager 2
Voyager 2 started recording emissions when it made its flyby of Saturn on 26 August 1981. During its crossing of the

it picked up a number of signals emitted by the rings and Saturn itself respectively. During the encounter with Uranus, Voyager 2 recorded the sounds of Uranus during its closest approach on 24 January 1986 at a distance of 81500 km (50,641.9 mi) and during its retreat towards Neptune on 26 January. It managed to pick up signals from Uranus' Rings during closest approach and Miranda when it flew by on 24 January. On 25 August 1989, Voyager 2 made its final planetary flyby, Neptune. Voyager's final PRA objective was to record emissions of Neptune's north pole on closest approach.
