（概要）
The Voyager programme consisted of a pair of unmanned scientific probes,
Voyager 1 and Voyager 2.
They were launched in 1977 to take advantage of a favourable planetary alignment.
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.
These probes were built at JPL (Jet Propulsion Lab) and were funded by NASA.
