Japanese Space Tech Startup Letara Raises $16M to Expand Beyond Thrusters

Hokkaido-based space technology startup Letara has secured $16 million in Series A funding to expand its product line from satellite propulsion thrusters into comprehensive orbital maneuvering and space logistics hardware.

Letara proprietary hybrid propulsion engines utilize safe, non-toxic solid plastic fuel paired with high-pressure liquid oxidizers, providing commercial satellite operators with a cost-effective alternative to toxic hydrazine propellants. The new capital will fund scalable automated manufacturing plants and orbital flight validation missions scheduled for late 2026.

As commercial satellite constellations crowd Low Earth Orbit (LEO), demand for reliable collision avoidance systems and precise end-of-life deorbiting motors has surging dramatically. Letara aims to establish its modular hybrid engines as the standard propulsion bus for smallsat and cubesat operators across Asia-Pacific and global aerospace markets.
