Plans to build Voyager
Starting in the late 1970s, the giant outer planets Such as Jupiter, Saturn, Neptune and Uranus, would line up in such a way that single spacecraft might be able to hop from one to the next, using the gravity of each one to keep speeding it on its way. Taking advantage of this alignment NASA approved the Voyager Project plans, and began planning to send two spacecrafts into interstellar space -

Golden Records
The Voyager Golden Records are phonograph records that were included aboard both Voyager spacecraft. They 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. -
Launch of Voyager 2
Voyager 2 launched on August 20, 1977, from Cape Canaveral, Florida aboard a Titan-Centaur rocket. The probe's primary mission objectives included flybys of Jupiter, Saturn, and Saturn's large moon, Titan. -
Launch of Voyager 1
Voyager 1 was launched, by NASA, 16 days after its twin (Voyager2). Having operated for 38 years, 6 months and 25 days, the spacecraft still communicates with the Deep Space Network to receive routine commands and return data. -
Voyager 1 Flyby Jupiter
Voyager 1's closest approach to Jupiter occurred March 5, 1979. Voyager 1 completed its Jupiter encounter in early April, after taking almost 19,000 pictures and many other scientific measurements. -
Voyager 2 Jupiter flyby
Voyager 2 picked up the baton in late April and its encounter continued into August. They took more than 33,000 pictures of Jupiter and its five major satellites. -
Data found Around Jupiter
voyager found Erupting volcanoes on Jupiter's moon Io, which has 100 times the volcanic activity of Earth -
Voyager 2 flyby Saturn
Voyager 2 probed Saturn's upper atmosphere with its radio link to gather information on atmospheric temperature and density profiles. Voyager 2 found that at the uppermost pressure levels , Saturn's temperature was 70 kelvins , while at the deepest levels measured the temperature increased to 143 K . The north pole was found to be 10 kelvins cooler, although this may be seasonal. -
Voyager 1 flyby Saturn
Voyager 1 became the second spacecraft to flyby Saturn. Voyager 1 found an abundance of new data regarding the planet and its moons. -
Data of Saturn Found by Voyager 1
it found three new moons, Prometheus, Pandora, and Atlas. Prometheus and Pandora are shepherding moons of the F-rings, and Atlas is a shepherd of the A-rings. -
Voyager 2 flyby of Uranus
Voyager 2 shows crescent of Uranua NASA's Voyager 2 spacecraft flew closely past distant Uranus, the seventh planet from the Sun. At its closest, the spacecraft came within 81,500 kilometers (50,600 miles) of Uranus's cloudtops on Jan. 24, 1986. -
Voyager 2 Discoveries of Uranus
Voyager 2's images of the five largest moons around Uranus revealed complex surfaces indicative of varying geologic pasts. The cameras also detected 10 previously unseen moons. Several instruments studied the ring system, uncovering the fine detail of the previously known rings and two newly detected rings. Voyager data showed that the planet's rate of rotation is 17 hours, 14 minutes. -
Voyager 2 flyby of Neptune
In the summer of 1989, NASA's Voyager 2 became the first spacecraft to observe the planet Neptune, its final planetary target. Passing about 4,950 kilometers (3,000 miles) above Neptune's north pole, Voyager 2 made its closest approach to any planet 12 years after leaving Earth in 1977. Five hours later, Voyager 2 passed about 40,000 kilometers (25,000 miles) from Neptune's largest moon, Triton, the last solid body the spacecraft will have an opportunity to study. -
Voyager 1crosses into Interstellar space
NASA's Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion kilometers) from our sun. -
Voyeger found by Ailens ?
Neither Voyager spacecraft is heading toward any particular star, but Voyager 1 will pass within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years. Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."
