Interstellar Technologies is developing Zero - small satellite launch vehicle. It is a two-stage rocket designed to provide space transportation services exclusively for small satellites, capable of launching payloads of up to 1,000 kg into low-Earth orbit (LEO). It is expected to be the world's first privately developed rocket to use liquefied biomethane (LBM) as propellant. LBM is produced from biogas derived from local livestock manure and launch costs are expected to be under 800 million yen once mass production begins. The company is also developing the DECA heavy lift vehicle, tailored to meet the demands of the 2030s and its own satellites, and plans to provide high-speed, high-capacity broadband services capable of connecting directly to smartphones, vehicles, and other devices.
