Zero Parasitic Power

Centrifugal droplet collection eliminates the electromagnetic systems that blocked LDR deployment for 30 years. Passive ceramic bearing and rotary fluid joint, both with direct ISS heritage.

55 kW Disk Radiator

The D3 spinning disk rejects 55 kW, powering 64 GPUs in a 916 kg satellite. 10m radius disk deploys like a solar sail. Falcon 9 rideshare compatible.
