The Momo-4 rocket will carry a research device developed by Kochi University of Technology and release a paper plane in space as part of an experiment proposed by Castem Co., a precision parts manufacturer based in Fukuyama, Hiroshima Prefecture, that provided some of the funding for the project.
Momo is a Japanese sounding rocket capable of delivering 20 kg to a height of 100 km. It is privately developed by Interstellar Technologies Inc. (IST). The single stage Momo is powered by a pressure-fed engine fueled with ethanol and liquid oxygen. The engine is gimbaled for steering, with cold gas thrusters providing roll control.See MOMO Details
