KENNEDY SPACE CENTER, FLA. - Bionetics Project Engineer William McLamb examines a petri dish containing C. elegans nemotodes (round worms).  These specimens were found in a Biological Research in Canisters (BRIC) container, a middeck experiment that was among the Columbia debris recovered in East Texas. The worms are descendants of those that were part of an experiment that flew on Columbia's last mission, STS-107.  The experiment was designed to verify a new synthetic nutrient solution for an International Space Station (ISS) "model" specimen planned to be used extensively for ISS gene expression studies and was sponsored by the NASA Ames Research Center. Scientists are now looking over the experiment at KSC to determine if it will yield any scientific results.  The investigation into the cause of the Columbia accident is ongoing. KSC-03pd1350

Conversion. Copper and brass processing. Many parts and products used by the Army and the Navy must stand up under severe service conditions. Here the strength of a specimen of brass is being determined. The results of these tests enables engineers to select metals that have the strength and stiffness needed for various machined parts for guns and equipment. This testing machine records the tensile of yield strength of a metal specimen--its resistance to being pulled apart. A specimen in the machine is pulled until it breaks, and the load necessary to break is recorded. A meter attached to the specimen measures the amount of stretching.
