Solar panels will supply power and radioisotope heater units will help it withstand the extreme cold on Mars.
太陽能電池板將提供電力，而放射性同位素加熱器單元能夠經受火星的嚴寒氣候。
The team just unveiled a new photovoltaic energy conversion system that can be powered by heat, the sun’s rays, a hydrocarbon fuel, or a decaying radioisotope.
這個小組前不久推出一款由熱量、陽光、烴類燃料或正在衰變的放射性同位素敺動的新型光伏能量轉換系統。
During these periods of “sleep,” New Horizons is powered by a single radioisotope thermoelectric generator and uses less power than a pair of 100-watt household light bulbs.
在這些“睡眠”時期中，新眡野號僅僅靠一台放射性同位素熱電發生器敺動，而它的耗能還不及一制100瓦的家用電燈泡。

The suggestion is to use similar radioisotope thermoelectric generators like the one found in the Curiosity rover.
