MRCF, LP, NPS Vehicle Focal
HAB, MLV, MR Power Contact
Mass: 0.38 mt
Stowed Volume: 21.5 m^3
Power: 0.0 kWe
Aluminum poles & nylon mass included
Mobile system so rocket can be constructed on the launch pad.
LP (Launch Pad):
Launch gantry only
MLV Mass Lifted: 500 mt
Power: 85 kWe
5 minute lift time
Highly dependent on finalized mass of MLV
1.0 km from HAB requires significant cabling mass at higher (1.0 MWe) power 6
On the order of 1 mt

24% CBC cycle efficiency 9
Additional masses baselined against documentation 1,2,3,9
Surface reactors have higher power conditioning requirements, accounting for higher overall masses, but the fundamental reactor is the same
Thermal radiator concept
Radiators are also aluminum skin of the EP system and are deployable on the surface.
Surface power conditioning and distribution
Masses and volumes not entered into the reactor bed.
With a safety zone of 6 meters, the HAB will be placed 100 meters to 400 meters from the nuclear power source without significant riskEP / NPS Reactor Sizing Logic (1)
