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.
Using DARUMA Micro (30 kg wet mass):
- Capable of accelerating a 10 kg payload to 1,100 m/s
- Capable of accelerating a 100 kg payload to 400 m/s
- Capable of accelerating a 300 kg payload to 130 m/s
- Capable of orbit transfers from Geostationary Transfer Orbit (GTO) to Near Rectilinear Halo Orbit (NRHO)
Integrated cold-gas nozzles, and main-engine re-ignition technologies enable rapid and precise orbital adjustments as necessary
Deliberately lower the satellite into Earth's atmosphere,
for debris removal, or sample return etc.
Combustors, Piping, Tanks, Simple CPU, Batteries
Exterior wall panels, Attitude control devices
Scalable design and manufacturing due to 3D printer
Increasing storage density and minimizing safety control during oxidizer filling
will be provided as hardware set
