Voyager 1 & 2 Missions to Jupiter!

:::VOYAGER 2 MISSION TO JUPITER:::

Voyager 2

Launch date: Aug. 20, 1977

Even though Voyager 2 launched 16 days before Voyager 1, it took its time getting to Jupiter and arrived four months after Voyager 1. Ten months into the flight, well before the spacecraft reached the planet, Voyager 2's primary radio receiver failed. The back-up receiver kicked in, but it proved to be somewhat unreliable. Controllers tried to revive the primary receiver - without any luck, so they were forced to continue with the back-up. Despite its irregularities, the back-up receiver worked admirably during the Jupiter fly by, and continues to work to this day. Voyager 2 flew by Jupiter on July 9, 1979, taking about the same number of images as Voyager 1 (18,000 images of Jupiter and its moons). Between the two spacecraft, three new moons were discovered as well as a thin, dark ring around Jupiter. Voyager images of Jupiter's moon Io revealed active volcanoes - the first ever discovered on another body besides Earth. Voyager 2 continued on to Saturn, Uranus and Neptune. It is now heading out of our solar system. The above picture is the Voyager being tested in the Thermal Vacuum Chamber.

:::VOYAGER 1 MISSION TO JUPITER:::

Voyager 1

Launch date: Sept. 5, 1977

Launched 16 days after Voyager 2, Voyager 1 was on the fast track to Jupiter and actually arrived at gas giant planet four months ahead of the other spacecraft. Voyager 1 flew by Jupiter on March 5, 1979, taking over 18,000 images of planet and its moons. Voyager 1 then continued on to Saturn. During the two Voyager fly bys of Jupiter, three new moons were discovered as well as a thin, dark ring around the planet. Voyager images of Jupiter's moon Io revealed active volcanoes - the first ever discovered on another body besides Earth.
