  Voyager
Voyager 2 was launched first, on August 20, 1977, followed by Voyager 1, which was put on a faster, shorter trajectory to Jupiter on September 5, 1977.
As Voyager 2 passed Neptune and began its journey to the edge of the solar system, its camera was rotated to look back at the planets and take one last parting shot of the solar system.

  Voyager 2 - Wikipedia, the free encyclopedia
Voyager 2 is arguably the most prolific space probe ever launched, visiting 4 planets and their many moons with powerful cameras and a multitude of scientific instruments, at a fraction of the money later spent on specialized probes such as the Galileo spacecraft and the Cassini-Huygens probe.
Voyager 2 found that at the highest levels (70 millibars or 7.0 kilopascals) Saturn's temperature was 70 kelvins (-203.15°C), while at the deepest levels measured (1200 millibars or 120 kilopascals) the temperature increased to 143 kelvins (-130.15°C).
Voyager 2, as of April 2006, is at -52.51° declination and 19.775hrs Right Ascension, placing it in the constellation Telescopium.

 Voyager program - Wikipedia, the free encyclopedia
Voyager is also the name of a planned series of unmanned probes to Mars, cancelled in 1968.
Voyager was actually a scaled back version of the Grand Tour program of the late 1960s and early 1970s to send a pair of probes to fly by all the outer planets (scaled back because of budget cuts).
Voyager 1 and Pioneer 10 are also the most widely-separated man made objects in the Universe because they are travelling in roughly opposite directions from the sun.

 Voyager - Science - Planetary Voyage
The prime Voyager mission to Jupiter and Saturn brought Voyager 1 to Jupiter on March 5, 1979, and Saturn on November 12, 1980, followed by Voyager 2 to Jupiter on July 9, 1979, and Saturn on August 25, 1981.
Voyager 2 was aimed to fly by Saturn at a point that would automatically send the spacecraft in the direction of Uranus.
Voyager 2 is also headed out of the solar system, diving below the ecliptic plane at an angle of about 48 degrees and a rate of about 470 million kilometers (about 290 million miles) a year.

Voyager 2 is speeding away from the Sun at a velocity of about 3.13 AU/year toward a point in the sky of RA=338 degrees, Dec=-62 degrees (-47.46 degrees ecliptic latitude, 310.89 degrees ecliptic longitude).

 NSSDC: Voyager Project Information
Preceeded by the Pioneer 10 and 11 missions, Voyager 1 and 2 were to make studies of Jupiter and Saturn, their satellites, and their magnetospheres as well as studies of the interplanetary medium.
Voyager 2 was then diverted to the remaining gas giants, Uranus (January 1986) and Neptune (August 1989).
Data collected by Voyager 1 and 2 were not confined to the periods surrounding encounters with the outer gas giants, with the various fields and particles experiments and the ultraviolet spectrometer collecting data nearly continuously during the interplanetary cruise phases of the mission.

 Voyager 495 boat steel and aluminum building kits and plans
The Voyager 495 radius chine kit is the latest refinement of this world cruising sailboat and has all the qualities that the Bruce Roberts designs are famous for.
The Voyager 495 is intended of serious offshore passagemaking and has proven so popular that we decided to re-work the design and make changes that seem so obvious once the first boats are completed.
The Voyager 495-2 is a culmination of all we have learnt in the past 33 years of designing similar boats.

Because of this, Voyager 2 could not see the moon Titan up close unlike its twin, but it allowed the probe to become the first spacecraft to travel to Uranus and Neptune, thus completing the so-called Grand Tour, a rare geometric arrangement of the outer planets only occurs once every 176 years [2].
Fortunately, ground crews were able to establish contact through the craft's low-gain antenna and activate it.
Voyager 2 found that at the highest levels (70 millibars or 7.0 kilopascals) Saturn's temperature was 70 kelvins, while at the deepest levels measured (1200 millibars or 120 kilopascals) the temperature increased to 143 kelvins.

 NASA - Voyager Enters Solar System's Final Frontier
Voyager 1 is traveling a lot and has crossed into the heliosheath, the region where interstellar gas and solar wind start to mix.
The strongest evidence that Voyager 1 has passed through the termination shock into the slower, denser wind beyond is its measurement of an increase in the strength of the magnetic field carried by the solar wind and the inferred decrease in its speed.
Voyager 1 is about 8.7 billion miles from the Sun and traveling at a speed of 3.6 AU per year while Voyager 2 is about 6.5 billion miles away and moving at about 3.3 AU per year.

Voyager 2's initial charge was to take over the primary mission duties at Jupiter and Saturn should anything prevent Voyager 1 from meeting those objectives, or should Voyager 1 discover anything so intriguing that it merited a closer look.
Voyager 2 flew by Jupiter at a distance of 722,000 kilometers (448,600 miles), and like its sister, returned rich images of the planet, its rings, and satellites.

 Voyager 1 Sails Past 100 AU- Planetary News | The Planetary Society
At the urging of Carl Sagan, co-founder of The Planetary Society, Voyager 1 turned its camera back inward toward the slowly receding Sun and snapped one last set of images of the planets, a sort of family portrait, before its cameras were shut down.
Each Voyager carries it own kind of "postcards" in the form of a golden record that Sagan was instrumental in creating.
"Voyager 1 has crossed that Termination Shock for the first time and is in the heliosheath where the wind has slowed down and is turning around to head down the tail of the heliosphere," Stone continued.
