PRODUCT MODEL

Propulsion for
    Small Satellites

Our product is a lineup of propulsion units for small satellite and spacecraft, based on technology developed under joint research with Hokkaido University, and planned for space demonstrations 2024. The propulsion units are being developed to accommodate the needs of a wide range of satellite and spacecraft sizes, from satellites that fit in the palm of your hand, to spacecraft that are large enough to transport human passengers. The propulsion system, which incorporates innovative patented technology developed through years of research by Hokkaido University and Letara, will be provided as a package with fuel included. You can follow recent events related to research and development development on the R&D Column page and  Letara's SNS.
