Here's one final fun fact the Persid meteor shower is the only meteor shower that has ever delayed a space shuttle launch. Back in 1993, the NASA Sts 51 launch was delayed due to concerns about the shower activity being forecast to be extremely heavy, increasing the chances that a spacecraft in Earth orbit could be damaged by a piece of the debris. Our thanks to Lauren Perkins from the NASA Marshall Space Flight Center for the information on this. For Urban legends and stranger truths. I'm Bob Dennis
