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.
OVERVIEW
Escaping
Earth Orbit
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
Orbital
Injection
- Capable of orbit transfers from Geostationary Transfer Orbit (GTO) to Near Rectilinear Halo Orbit (NRHO)
Orbital
Adjustment
Deorbit
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.
