There is confusion over why Voyager 2 launched before Voyager 1.
The reason is because Voyager 1 was to go on a different flight path from Voyager 2.
They had to launch each of them when the planets were in the right place in relation to the Earth and the spacecrafts would go where they were they were supposed to go.
Both spacecraft were launched from Cape Canaveral in the state of Florida.

On August 20, 1977, Voyager 2 was launched.
A famous aspect to the mission was the gold record. This had recorded sounds and pictures from Earth. It was for just in case either Voyager found alien life in space. The record was put on both spacecraft.
There was a song by Chuck Berry and the running joke was when the aliens heard it, they sent a message to Earth, Send more Chuck Berry.
The gold record.
Recently, Voyager 1 made news. She was close to what is called the Heliopause. It is considered the boundary between , I’ll call it inner and outer space. She is beyond the solar system, but not yet way out there.
