Voyager Program

11 Nov 2025

What was the primary reason for launching the Voyager probes in 1977, and how did this timing benefit their mission?

They were launched to study the Sun's solar flares during a period of high solar activity. They were launched to take advantage of a rare planetary alignment that allowed them to efficiently fly by multiple outer planets. They were launched to orbit Jupiter and Saturn permanently for long-term observation.
