# Astraeus. Ice cold resolve.

Orbital Operations builds high-thrust, cryogenic space vehicles for rapid response and dynamic in-orbit missions.

### Protection. Precision. Power.

**Defense**  
Space is now a contested domain. Astraeus is designed to patrol and protect U.S. assets in orbit, with the ability to intercept threats, deploy countermeasures, and reposition rapidly. Stationed in LEO with high-thrust cryogenic propulsion, it enables real-time response to adversarial maneuvers—turning months of lead time into hours.

**Commercial**  
Satellite operators face growing challenges in positioning, servicing, and deorbiting their assets. Astraeus offers on-demand mobility for repositioning, life extension, and end-of-life disposal, all without waiting for the next launch window. It’s a new paradigm for commercial operators seeking precision and autonomy in orbit.

**Infrastructure**  
Building the foundation for long-term space presence requires in-orbit fuel, power, and thermal systems. Astraeus supports future infrastructure with the ability to transport cargo, enable refueling, and demonstrate scalable cryogenic management. It’s the utility vehicle for the next generation of orbital construction and logistics.

### Outpace. Outmaneuver. Outlast.

**Cryogenic Engines**  
Astraeus leverages proven cryogenic engine technology derived from launch vehicles, adapted for continuous use in space. This heritage thrust system delivers high performance and reliability, enabling rapid maneuvers and sustained operations far beyond Earth’s atmosphere.

**Zero Boil-Off Storage**  
Using an advanced cooling system, Astraeus maintains cryogenic propellant at stable temperatures for long-duration missions. This zero boil-off capability allows the vehicle to loiter in orbit, always ready to engage without losing fuel to evaporation.

**Integrated Radiative Cooling**  
Rather than relying on traditional radiators, Astraeus integrates its thermal management system directly in its engine. This design reduces dry mass and complexity while efficiently dissipating heat—an elegant solution made possible by advanced materials and manufacturing.

**Refuelable = Reusable**  
Astraeus is built for long-term sustainability in orbit. It can be refueled using water-based electrolysis systems or through cryogenic propellant transfers from launch vehicles, unlocking true orbital persistence.
