The bat, seen clinging to the external fuel tank of the Space Shuttle Discovery before its launch on Sunday, apparently clung for dear life to the side of the tank as the spaceship lifted off. And what a ride. The shuttle accelerates to an orbital velocity of 17,500 milers per hour, which is 25 times faster than the speed of sound, in just over eight minutes. That's zero to 100 mph in 10 seconds. Did it make it into space? No one knows yet. But photos of Discovery as it cleared the launch tower showed a tiny speck on the side of the tank. When those photos were blown up, it became apparent that the speck was a bat. Flight director Paul Dye said no one has seen the bat since. "I heard that it was clinging to the tank at liftoff, but I don't think anyone has seen it since," he said.
