Voyager Mission Beginnings

NASA initiated the Voyager mission with an aim to take advantage of a rare planetary alignment that would allow for a grand tour of the outer solar system. It capitalized on a once-in-175-years opportunity, where the outer planets—Jupiter, Saturn, Uranus, and Neptune—would align in a way that could be used to slingshot spacecraft from one to the next, saving time and energy. This planetary alignment gave the Voyagers the chance to conduct up-close studies of these planets and their moons, a task before which humanity could only dream.

Voyager 1 and Voyager 2 Paths

  • Voyager 1’s trajectory was designed for a fast path past Jupiter and Saturn. After its encounter with Saturn, the spacecraft was flung by the planet’s gravity on a trajectory out of the solar system. On February 14, 1990, Voyager 1 took the famous “Pale Blue Dot” photograph before its cameras were deactivated to conserve power.

  • Voyager 2, following a longer, but more fruitful path, traveled past Jupiter, Saturn, Uranus, and Neptune, gathering extensive data on these planets and their moons. With each planetary encounter, its trajectory was refined for the next destination, culminating in its successful flyby of Neptune in 1989. Both Voyagers have now reached interstellar space, the region beyond the influence of the solar wind and the sun’s magnetic field.

As they continue their silent journeys through the cosmos, these twin spacecraft bear the Golden Record, a message from Earth to any form of life that might one day discover them. They endure as harbingers of humanity’s insatiable quest to explore and connect.
