Interstellar Technology Inc.'s unmanned MOMO-3 rocket reached 113.4 kilometers in altitude before falling into the Pacific Ocean during its May 4 flight. Company founder Takafumi Horie said it plans to launch its first orbital rocket within the next few years. Then there will be another rocket that can reach deep space, which his company hopes to achieve in about a decade, and eventually, Horie wants to develop an interstellar rocket.
