The Voyager Programm is a American space Programm that employs 2 robotic probes, Voyager 1 and Voyager 2 to study the outer Solar System. The probes were launched in 1977 to take advantage of a favorable alignment of Jupiter, Saturn, Uranus and Neptune. Although their original mission was to study only the planetary systems of Jupiter and Saturn, Voyager 2 continued on to Uranus and Neptune. The Voyagers now explore the outer boundary of the interstellar space; their mission has been extended three times and they continue to transmit useful scientific data. Neither Uranus nor Neptune has been visited by a probe other than Voyager 2.
On 25 August 2012, data from Voyager 1 indicated that it had become the first human-made object to enter interstellar space, traveling “further than anyone, or anything, in history”. As of 2013, Voyager 1was moving with a velocity of 17 kilometers per second (11 mi/s) relative to the Sun.Data and photographs collected by the Voyagers’ cameras, magnetometers and other instruments, revealed unknown details about each of the four giant planets and their moons. Close-up images from the spacecraft charted Jupiter’s complex cloud forms, winds and storm systems and discovered volcanic activity on its moon Io. Saturn’s rings were found to have enigmatic braids, kinks and spokes and to be accompanied by myriad “ringlets”. At Uranus, Voyager 2 discovered a substantial magnetic field around the planet and ten more moons. Its flyby of Neptune uncovered three rings and six hitherto unknown moons, a planetary magnetic field and complex, widely distributed auroras. Voyager 2 is the only spacecraft to have visited Neptune and Uranus.
The Voyager spacecraft were built at the Jet Propulsion Laboratory in Southern California and they were funded by NASA, which also financed their launches from Cape Canaveral, Florida.
Onboard the Voyager 1 and 2, NASA sent 2 disks named ‘golden records’. The records contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. Those records are considered as a sort of a time capsule.
Although neither Voyager spacecraft is heading toward any particular star, Voyager 1 will pass within 1.6 light-years’ distance of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years.
There is a NASA website, where you can find the status of these spacecrafts anytime. I will leave you a link!
