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.

Update at 7:28 p.m. ET: Suspect's Identity Confirmed.

For one, he says, "They keep most exterior doors secured, which is something they didn't pay much attention to before."
