Description

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. Momo v0 was replaced by v1 in 2021.

Interstellar Technologies, Inc. (Japanese: インターステラテクノロジズ（株） Hepburn: Intāsutera Tekunorojizu (kabu)) is a Japanese NewSpace company. It is a rocket spacelaunch company developing the MOMO launcher. Its stated goal is to reduce the cost of access to space. In 2017, it became the first Japanese company to launch a privately developed space rocket, though the launch was unsuccessful. The company plans to complete a rocket by 2020 that would be capable of launching small satellites into orbit.
