High Thrust Space Vehicles for Satellite Defense

YC W25

About the Company

At Orbital Operations, we’re developing a high thrust space vehicle for satellite defense. Our mission is to enable rapid-response orbital capabilities, executing maneuvers without hesitation and without regret.

Tech Stack

Our Cryogenic Propellant Management System (CPMS) allows us to store liquid hydrogen and liquid oxygen out in orbit. Designed for our Astraeus spacecraft, the CPMS paired with a 10,000 lbf engine enables high efficiency, high-thrust maneuverability in low earth, geosynchronous, and cislunar orbits.

Beyond defense, Astraeus is poised to transform commercial orbital logistics. It can slash LEO-to-GEO transit times from six months to just eight hours—unlocking new possibilities for satellite servicing, deployment, and beyond.
