travel travel, and never come back

The Voyager mission began 50 years ago and the two probes continue their long journey 23.3 billion kilometers from Earth. How far will this exploration program go?

Launched 15 days apart in the summer of 1977, first Voyager 2 and then Voyager 1, the Volkswagen Beetle-sized probes are now exploring interstellar space beyond the solar system. It’s the longest and most distant journey in history and it’s not over. The project exceeded all expectations: 85,000 images, 24 moons discovered. We come back to the genesis and the future of an extraordinary mission.

Traveler Traveler, and never come back.

We are pleased to receive Jean-Loup Bertaux, planetary scientist, emeritus research director at the CNRS at LATMOS and Philippe Henarejos, scientific journalist, editor-in-chief of the journal Ciel et Espace.
