Aggie Astronaut Makes Final Spacewalk

By  | 

Two spacewalkers, including Aggie Astronaut Michael Fossum, sheepishly lost a spatula in orbit on Wednesday.

But NASA engineers didn't mind much, because the two accomplished their main task of testing a method to apply emergency patches to a shuttle heat shield.

Discovery spacewalkers Piers Sellers and Mike Fossum improved on the method of applying a special mixture to repair the reinforced edges of a space shuttle.

There was only one thing missing from the spacewalk: Sellers' spatula.
It flew overboard, off the right side of the shuttle's payload bay.

The entire crew of Discovery will get a day off Thursday before starting to wind up the mission.
