NOTIONAL Missions
Next-generation GEO operations require highly maneuverable platforms built at scale. GEO Aries is enabling the future of GEO spaceflight with agile performance and a production-first design built for resilient, proliferated architectures.
PROLIFERATED GEO
GEO Aries is designed for serial production, enabling resilient proliferated architectures by replacing bespoke buses with scalable platforms.
GEO RPO MISSIONS
GEO Aries is optimized for agility with 800 m/s of available ΔV, 6DOF Hydrazine propulsion, and support for third-party RPO kits.
SPACE reconnaissance
Execute mission-critical space reconnaissance operations with persistent monitoring and responsive operations in geostationary orbit.

- Power: Payload orbit average power (OAP) is listed as End of Life (EOL) and assumes a 550km circular sun-synchronous orbit with sun-tracking for the duration of the orbit.
- Communications: Data rates listed are peak data rates.
- Propulsion: Listed prices do not include propellant.
- Launch Vehicle Integration: Listed LV integration pricing assumes Apex’s standard service and a US-based launch vehicle.
- Available payload volume and masses shown assume a Falcon 9 Rideshare envelope.


























- Up to 115 OAP.
- Communications: Data rates listed are peak data rates.
- Delta-v up to 800m/s.
- Assumes standard ESPA volume.


























- Power: Payload Orbit Average Power (OAP) means average power available to the payload during an orbit. OAP is quoted at End of Life (EOL) and is true for any orbit within the nominal orbit range. A yaw-steering sun tracking attitude leveraging the single-axis SADAs is assumed.
- Communications: Data rates listed are 95-percentile atmospheric conditions, 98-percentile worstearth location.
- Propulsion: Listed prices do not include propellant.
- Payload Mass: Listed available Payload Volume assumes a SpaceX Falcon 9 Full Plate XL.
- Launch Vehicle Integration (LVI): Listed LVI prices for Aries do not transfer to Nova.
