In 1977, NASA launched two spacecraft that would change our understanding of the outer solar system forever. Voyager 1 and Voyager 2 were built to explore Jupiter and Saturn, but Voyager 2 went on to visit Uranus and Neptune, becoming the only spacecraft ever to fly past all four giant planets.

In this episode of Orbital Briefing, Ron Walker explores the Voyager probes, their rare planetary alignment, their groundbreaking discoveries, and their journey into interstellar space. We look at the spacecraft architecture, the gravity assists that made the mission possible, the science that transformed distant planets into real worlds, and the Golden Record, humanity’s message to the stars.

From Jupiter’s storms and Io’s volcanoes to Saturn’s rings, Uranus’s tilted system, Neptune’s winds, and the Pale Blue Dot, Voyager is more than a NASA mission. It is a story about science, engineering, memory, curiosity, and the hope that something of Earth might endure.

This is the story of Voyager 1, Voyager 2, the Golden Record, and humanity’s message to the stars.

Topics include: Voyager 1, Voyager 2, NASA, Golden Record, Carl Sagan, Ann Druyan, Jupiter, Saturn, Uranus, Neptune, interstellar space, Pale Blue Dot, deep space exploration, and the history of spaceflight.
