Bat Clung to Space Shuttle During Launch

(March 17) -- A small bat that was spotted blasting off with the space shuttle Sunday and clinging to the back side of Discovery's external fuel tank apparently held on throughout the launch.

NASA hoped the bat would fly away before the spacecraft's Sunday evening liftoff, but photos from the launch now show the bat holding on for dear life throughout the fiery ride.

A bat hangs on to the space shuttle Discovery during the countdown to its launch on Sunday. NASA workers noticed the bat near the spacecraft before the launch and hoped it would fly away, but the agency believes the animal stayed and died on the shuttle.

"He did change the direction he was pointing from time to time throughout countdown but ultimately never flew away," states a NASA memo obtained by SPACE.com. "Infrared imagery shows he was alive and not frozen like many would think ... Liftoff imagery analysis confirmed that he held on until at least the vehicle cleared [the] tower before we lost sight of him."

Officials at NASA's Kennedy Space Center in Cape Canaveral, Fla., where Discovery launched from a seaside pad, said the bat's outlook after launch appears grim.

"Based on images and video, a wildlife expert who provides support to the center said the small creature was a free tail bat that likely had a broken left wing and some problem with its right shoulder or wrist," NASA officials said Tuesday. "The animal likely perished quickly during Discovery's climb into orbit."

Because the Kennedy Space Center is also home to Florida's Merritt Island National Wildlife Refuge, NASA's launch pads are equipped with several countermeasures, including warning sirens, to ward off birds and other wildlife. NASA also relies on radar to make sure large flocks of birds won't be struck by the shuttle during liftoff.

But the bat on Discovery's tank did not budge, even after engine ignition.

The bat was perched between one quarter and one third of the way up on the north side of the fuel tank, which is the side that faces away from the orbiter. NASA estimated the surface temperature of the tank at that location was between 58 and 70 degrees Fahrenheit, even though the canister was filled with super-cold liquid hydrogen and liquid oxygen.

In the hours before Discovery's liftoff, NASA's Final Inspection Team (called the "ICE team") investigated whether the creature would pose a risk to the shuttle if its body impacted the orbiter's sensitive heat shield tiling. Ultimately, NASA officials signed a waiver confirming that the bat was safe to fly with.

"The bat eventually became 'Interim Problem Report 119V-0080' after the ICE team finished their walkdown," the memo said. "Systems Engineering and Integration performed a debris analysis on him and ultimately a Launch Commit Criteria waiver to ICE-01 was written to accept the stowaway."
