Globally, Efficiently, andIndependently

The global small satellite market has a launch bottleneck. We're closing it.

CRUX operates a reusable launch vehicle family from Patagonia, Argentina, purpose-built for dedicated SSO missions. 250 kg and 1,000 kg payload classes. Weekly cadence. Sub-$5,000/kg target cost. No rideshare compromise.
