A bat was seen clinging to the external fuel tank of the Space Shuttle Discovery before its launch on Sunday, and it apparently held on for dear life as the spaceship lifted off. The shuttle accelerates to an orbital velocity of 17,500 miles per hour, which is 25 times faster than the speed of sound, in just over eight minutes. It is not known whether the bat made it into space.

Three new species of bacteria which are not found on Earth, and which are highly resistant to ultra-violet radiation, have been discovered in the upper stratosphere by Indian scientists.
