Abstract: A payload control system and payload controller for a payload onboard an outer space vehicle having a host computer system are provided. The payload controller includes a unitary compact control unit mounted on a circuit board. The control unit includes a processor, memory, display device control logic, input device control logic, and data input/output control logic. A plurality of interfaces located about the board surfaces provide communication with payload and host system components. A computer readable storage medium mounted on the circuit board stores information to control the payload when the payload is in outer space. The information stored in the computer readable storage medium is non-permanent so that the payload controller may be re-used for different payload experiments. The unitary compact control unit includes sufficient components to function as a stand alone computer capable of running an operating system while supporting a display device and an input device.

Abstract: An autonomously operated automated food dispenser provides sustenance to one or more animals at prescribed intervals. The dispenser is portable and suitable for use for animals in space vehicle life support systems. A micro-controller controls operation of the outlet valve of a food reservoir that contains a food paste maintained under pressure by a pressurized gas source. Predetermined volume of food paste are extruded through the outlet upon the micro-controller's command. The food cannister is characterized by a novel two part assembly and houses a rolling diaphragm. Pressurized gas is applied to the bottom of the diaphragm, allowing the diaphragm to roll against the food paste, when the outlet valve is opened.
