A University Microsatellite as a MEMS-Based Propulsion Testbed
Abstract
Using reconfigurable and adaptable networks of micro/nanosatellites to support cost-effective space missions is a popular new direction in the space community Micropropulsion systems, which control a satellite's dynamics and attitude, are instrumental to the success of such missions. Since the overall resources available for a micro/nanosatellite are more restricted than for a single large satellite, the micropropulsion system must be lightweight, low power and low cost. This study provides an initial estimate of the mission requirements that drive a micropropulsion design for a university-built microsatellite. It is demonstrated, through a pragmatic joint venture between a university and a government laboratory, that university satellites are an effective testbed for unconventional new technologies. An example of a university satellite that successfully served as a technology demonstration platform as well as an effective education instrument is presented. A follow-on mission, which will be the platform for flight testing a micropropulsion module, is then described. Two candidate micropropulsion systems, the free molecule micro-resistojet and a cold-gas micronozzle, have been studied for applicability to the prescribed mission. The preliminary study concludes that the free molecule micro-resistojet is the more appropriate micropropulsion system for this particular mission.
