Dynamic - Rankine, Brayton, Stirling Waste-Heat Radiators Conventional Fin-and-Tube, Liquid Droplet, Moving Belt, etc. Heat Pipes, Pumped Fluid Loop Electrodynamic Tether Hybrid Nuclear-Thermal / Nuclear-Electric - Use Nuclear-Thermal rocket (e.g., Solid-Core NERVA) for high T/W in high gravity field (and low-I sp ) to minimize gravity losses and trip time, then switch over to Nuclear-Electric propulsion for low-T/W, high-I sp transfer.
