Mission of Voyager 1 and 2

The extravagant mission of Voyager 1 and 2
This mission is continuing on their more-than-37-year journey since their 1977 launches. The mission is the most helpful space craft because of how it takes pictures of the solar system and helps scientist know how our planets are moving, and taking place trough the different seasons. On September 5, Voyager 1 launched.
Your probably wondering whats a voyager,well a voyager is space craft that helps scientist to look at the what the planets look like , one thing is that this mission had is two mission , so that means there is a voyager 1 and 2.
This mission was the very first mission to be able go the farthest and than any space craft and human being, these Voyagers were to conduct closeup studies of Jupiter and Saturn, Saturn's rings, and the larger moon's of the two planets.
Voyager 1's trajectory, designed to send the spacecraft closely past the large moon Titan and behind Saturn's rings, bent the spacecraft's path inexorably northward out of the ecliptic plane -- the plane in which most of the planets orbit the Sun. Voyager 2 was aimed to fly by Saturn at a point that would automatically send the spacecraft in the direction of Uranus.
After Voyager 2's successful Saturn encounter, it was shown that Voyager 2 would likely be able to fly on to Uranus with all instruments operating. NASA provided additional funding to continue operating the two spacecraft and authorized JPL to conduct a Uranus flyby. Subsequently, NASA also authorized the Neptune leg of the mission, which was renamed the Voyager Neptune Interstellar Mission.
Eventually, between them, Voyager 1 and 2 would explore all the giant outer planets of our solar system, 48 of their moons, and the unique systems of rings and magnetic fields those
Both spacecraft will continue to study ultraviolet sources among the stars, and the fields and particles instruments aboard the Voyagers will continue to search for the boundary between the Sun's influence and interstellar space. The Voyagers are expected to return valuable data for two or three more decades. Communications will be maintained until the Voyagers' nuclear power sources can no longer supply enough electrical energy to power critical subsystems.
Voyager 1 and 2 were designed to take advantage of a rare planetary alignment to explore the outer solar system. Voyager 2 targeted Jupiter, Saturn, Uranus and Neptune. Like it's sister spacecraft, Voyager 2 also was designed to study the edge of our solar system beyond the planets.
Accomplishments: Voyager 2 is the only spacecraft to study all four of the solar system's giant planets at close range. It is now exploring the outermost reaches of where the solar wind and the sun's magnetic field dominate space. In September 2007, it crossed the termination shock (where the speed of the solar wind drops below the speed of sound) at 84 AU (about 13 billion km from the sun, more than twice the distance to Pluto). Since then, Voyager 1 has been operating in the heliosheath environment, a region about 40 to 50 AU (3.7 billion to 4.7 billion km) thick where the solar wind mixes with the interstellar wind.
