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(jīng)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驅(qū)動的新型光伏能量轉(zhuǎn)換系統(tǒng)。
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，新視野號僅僅靠一臺放射性同位素?zé)犭姲l(fā)生器驅(qū)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.

As the radioisotope decays, it produces heat energy that is converted by thermoelectric materials into the electricity that powers the space probe.
