Voyager 2 was launched first on August 20, 1977, followed by Voyager 1, which was launched on September 5, 1977. Although Voyager 2 was the first to launch, Voyager 1 ultimately became the first spacecraft to enter interstellar space in 2012. Both missions have provided invaluable data about the outer planets and continue to communicate with Earth.
Voyager 1 was launched on the 5th of September 1977 and Voyager 2 was launched before voyager 1 on the 20th of August 1977.
Voyager 1 was launched on September 5, 1977, and Voyager 2 was launched on August 20, 1977.
There are two Voyager spacecraft. Voyager 2 was launched on August 20 1977. Voyager 1, despite its no.1 ranking, was launched second on September 5 1977.
Voyager 2 was sent out first to allow it to take full advantage of an unusually convenient alignment of the planets allowing it to visit Uranus and Neptune as wellVoyager 1 was launched after voyager 2, but on a faster trajectory which allowed it to reach Jupiter and Saturn before voyager 2.
Space probes voyager 1 and Voyager 2 were launched in 1977
Two of the US space probes are Voyager I and Voyager 2. NASA launched Voyager I on September 5, 1977. Voyager II ended up being launched before Voyager I on August 20, 1977.
There were many Pioneer missions. Please see link for more information
