“There’s no place like home…”

I didn’t ‘Wave at Saturn’ on 19 July when the Cassini probe, orbiting the gas giant, was taking a high-definition image of the view back home.  I don’t think it encouraged a proper sense of perspective…  But the resultant image is stunning.

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. …
