Fifty years ago, on Dec. 14, 1962, reporters gathered for a press briefing at NASA headquarters and heard an unearthly sound: radio signals being beamed back by a spacecraft flying within 22,000 miles of Venus.

The Mariner 2 mission to Venus was the first time any spacecraft had ever gone to another planet.

The world isn't going to end next Friday, but Dec. 21, 2012, has come to be known as the Mayan apocalypse because that's when the Mayan calendar ends. As scientists have told us repeatedly, the end of the calendar year was actually a time for celebration and renewal — the equivalent of an ancient New Year's Eve.

IRA FLATOW, HOST:

Up next, what is intelligence? What is thought? What does it really mean to have a mind? And if we can answer those questions, is it possible for people to reverse-engineer the process and build an artificial mind? Sure, there are things like Siri, which can understand enough of your question to pull up directions to the restaurant, and there's IBM's Watson, which took on human contestants in a game of "Jeopardy!" and won. But how to jump the gap from those to something everyone would agree is truly intelligent?
