With the increasing usage of microsatellites in recent years, the demand for propulsion systems has also increased. Therefore, in this study, we developed a Microsatellite-Friendly Multi-Purpose PROPulsion system (MFMP-PROP) using 60 wt.% H2O2 as a basic propellant. MFMP-PROP can operate in the monopropellant mode for small impulse bit and the bipropellant mode for a relatively large thrust with a comparably high specific impulse. In this paper, the bipropellant mode is introduced and described, including reports on the progress concerning their research and development. As an approach to stable combustion, the effects of mixing ratio, preheating temperature, and mass flow rate on the operating characteristics were evaluated. As a result, we demonstrated a reliable and stable combustion range. The lifetime and continuous operating time were evaluated to investigate durability. As a result, 132 ignitions and 7,900 s of total operating time were achieved, during which the propellant consumption reached 1,375 g.

This paper proposes to hold “Ig Satellite Design Contest,” in order to expand our space utilization by means of content-based satellites in the stream of recent microsatellite development. Going back to the history of the recent microsatellite, such a content-based satellite is positioned as the third-generation one. Ig Satellite Design Contest stands on the position of the two policies, that is, the satellite is chip in porridge for practical effect, but is to bring pleasure or happiness to people, or to stimulate access to the space and our future space activities.

We organize Ig Satellite Design Contest to collect the NEEDS and to establishment of NEEDS database for microsatellite. It will be polestar for the satellite developers. This paper shows an example of NEEDS collection and derivation of the key technologies from the NEEDS, which should offer a strategic direction to the SEEDS, the satellite developers for example.
