The day people saw the Earth and the Moon together – level 2

18-09-1977

Voyager 1 is a space probe that started its journey on September 5, 1977. The probe’s goal was to fly to Jupiter and Saturn and then continue to interstellar space. People had big expectations of the mission. They expected to see its first big results in one year because that was the time that was necessary to travel to Jupiter.

However, the first big success of the mission came already after 13 days when Voyager 1 sent a picture of the Earth and the Moon together. It was the first time when both worlds were seen in one picture.

Difficult words: probe (a spaceship without people that travels through space), interstellar (between the stars in the sky), expectation (a hope that something good will happen).

What was the first major success of the Voyager 1 mission and how soon did it happen after its launch?
