Stop trying to fit a standard bus

Proteus MERCURY ONE spacecraft on orbit above Earth

Standard buses make your payload adapt to a fixed bus ICD. That means compromised mission objectives, plus integration surprises that add cost, schedule, and risk.

We don't have a bus ICD.

We start with your payload ICD and generatively design a payload-tailored bus around your mission objectives, using a flight-proven design system and TRL 9 components.

Custom spacecraft, autonomously designed around your payload, not one-size-fits-all. We excel at rapidly solving tough power, thermal, pointing, and jitter challenges.
