【Abstract】：The design and subsystems of the OE-6 Orbiter Ejector are described. ^The purpose of the Orbiter Ejector, which is placed in a cannister in the cargo bay of the Space Shuttle Orbiter, is to place six spheres in orbit for the calibration of various radar and optical instruments worldwide. ^The OE-6 is designed to eject these spheres into precise orbits via a geared rotating ring driven by an electric motor that releases pins that in turn release compressed springs; these springs force the spheres through tubes out and into their orbits. ^The composition of the spheres and the sphere's orbit parameters are selected on the basis of satisfying a variety of constraints, including the separation time, activation time, sphere-orbit time, orbital safety, and sphere collisions with each other. ^(I.S.)
