Spacecraft Everlasting

A short but interesting story in Discover magazine about whether the Voyager 1 spacecraft has reached the edge of the solar system, plus some news about the nearly ancient Pioneer probes. I couldn't fit this into the piece itself, but a few of the scientists noted that the real news here might be that these spacecraft are still working. They were launched in the 1970s and designed even earlier. That's pretty amazing engineering.

What did I forget? Ah, right, the story. Read it here.
