Abstract
Abstract A module incorporating at least one flat end cap is positioned within the payload of the Space Shuttle or other space vehicle to enhance the capabilities of the payload area. The flat end cap reduces the required volume in the launch vehicle to be occupied by the module and provides for efficient use of the interior space of the Space Shuttle by providing more flat surfaces to which necessary equipment can be fastened. The module is truncated, thus adding another flat surface, i.e., a ceiling, to the interior of the vehicle. The truncated top of the module is capable of separate integration and carries additional experiments within racks which can be attached to its interior surface. The module can be fabricated from aluminum members in an aircraft type fashion of construction, or can be assembled from existing or modified Space Lab hardware. The module provides a full scope of services within its pressurized interior and will enhance the carrying capability of the shuttle with respect to handling both personnel and cargo.
