Stardour
Stardour is a Hyderabad-based in-space transportation startup developing the Lucas Orbital Transfer Vehicle for orbital logistics across LEO, GEO and potentially lunar/Martian missions. Lucas is designed for satellite deployment, orbit maneuvering, in-space refueling, spacecraft servicing, life extension and debris removal. Stardour test-fired what it describes as India's first in-house hydrogen-oxygen engine at IISc Bengaluru, targeting a maiden Lucas flight in Q3 2027.
