Voyager: Humanity’s Farthest Journey

While waiting for Endeavour’s final voyage, you can catch up, metaphorically, with the ongoing scientific odyssey of those other still-nimble Voyagers as they head towards the vastness of interstellar space.  ( Image credit: NASA/JPL-Caltech)

NasaTV has Thursday’s special science presentation on the mission with a panel of the Voyager team – including Ed Stone, who’s been there since 1972, and Ann Druyan, creative director of the group, led by Carl Sagan and Frank Drake, who put together the Golden Record both Voyagers carry.

If you want to feel depressed, compare that Golden Record with our most recent attempted interstellar communication…

ANYhoo… Here’s the presentation.

And from the associated Nasa/JPL press release

“A billion years from now, when everything on Earth we’ve ever made has crumbled into dust, when the continents have changed beyond recognition and our species is unimaginably altered or extinct, the Voyager record will speak for us,” wrote Carl Sagan and Ann Druyan in an introduction to a CD version of the record.

Some people note that the chance of aliens finding the Golden Record is fantastically remote. The Voyager probes won’t come within a few light years of another star for some 40,000 years. What are the odds of making contact under such circumstances?

On the other hand, what are the odds of a race of primates evolving to sentience, developing spaceflight, and sending the sound of barking dogs into the cosmos?

Expect the unexpected, indeed.

Finally, here’s the first animation from the Voyager presentation.  Destination: Interstellar space, indeed.
