In the background are stowage lockers and a CFES trainer-- part of the Shuttle one-g trainer at NASA's Johnson Space Center (JSC).  Walker, an engineer at McDonnell Douglas Astronautics Co. in St. Louis, Missouri, will be the first Shuttle payload specialist to represent a project designed for commercial purposes.  As payload specialist, his job will be to run the materials electrophoresis-operations-in-space project.  The project is aimed at separating large quantities of biological materials in space for ultimate use in new pharmaceuticals.  The photo was taken by a McDonnell Douglas photographer.
