In 1977, NASA launched two space probes that would revolutionize our understanding of the solar system and beyond: Voyager 1 and Voyager 2. These devices, designed to explore outer planets, have accomplished unrivalled missions, providing valuable data and new images that continue to inspire scientists and the general public. Back to this extraordinary adventure started More than forty years ago.

The historical launch of Voyager 1 and 2 probes in 1977

On 5 September 1977, Voyager 2 was the first to be launched from Cape Canaveral, followed by Voyager 1 on 20 September, although the latter was sent on a more direct and faster trajectory. These probes were put into orbit at a time when space conquest was booming, with the main objective of studying Jupiter and Saturn closely, as well as their moons. Accuracy of trajectories and on-board technological innovations allowed the two probes to benefit from a unique launch window, called gravitational assistance, to sway towards the limits of the solar system.

Extraordinary missions to travel in outer space

Beyond their initial mission, Voyager 1 and 2 continued their journey, sending crucial information about Uranus and Neptune, planets never explored before. Voyager 2 remains to date the only probe that flew over these icy giants. Even more impressive, Voyager 1 became the object made by the most distant man on Earth, crossing the heliopause boundary in 2012 to enter interstellar space. The two probes always transmit data, providing clues on the nature of the interstellar medium and the solar wind, a technical and scientific feat that establishes a unique bridge between humanity and the infinite universe.

Voyager 1 and 2 probes remain emblematic symbols of human curiosity and technical ingenuity. Their launch in 1977 opened a new era of space exploration, offering unexpected prospects for our solar system and beyond. As these space travelers continue their silent journey in vastness, they recall how our thirst for knowledge can push the boundaries of the possible.
