Minnesota-native Heidi Stefanyshyn-Piper returned to space this week aboard the shuttle Endeavor. What kind of "weather" will Heidi be walking in? And how does space weather affect the weather on Earth? We find out from Bill Murtagh from NOAA's Space Weather Prediction Center. We also get winter car care tips from Pete Frits of St. Paul's Park Service. And our Website of the Week is a double-header!
