Fans of NASA's Endeavour space shuttle are counting down with anticipation for Endeavour's second launch attempt, currently slated for 8:56 a.m. EDT on Monday. The first launch attempt on April 29 ended a few hours before the planned liftoff when a heater in one of the ship’s onboard power generators failed.
Now the problem has been fixed, the weather seems to be cooperating, and if Endeavor is deemed go for launch on Monday, it will be carrying a peculiar live cargo: an intrepid three-inch creature named Euprymna scolopes, a.k.a., the Hawaiian bobtail squid.The squid are part of a microgravity experiment to determine the impact of space (if any) on beneficial bacteria, according to Jamie Foster of the University of Florida in Gainesville.
See, this species of squid has a built-in flashlight that uses bacteria as batteries to help navigate murky nighttime waters, hunt for prey, and hide from predators. There is a convenient little cavity on the squid's underside that serves as home to colonies of bacteria known as Vibrio fischeri.
