The team compared it to conventional battery and Plutonium powered systems, both of which have deficiencies that are overcome by SCEPS.

该团队比较了它与传统的电池和钚供电系统，这两者都有由SCEPS（所能）克服的缺陷。

Even the heat from the chunk of plutonium that ACTS as the spacecraft's battery produces a smidgen of thrust, and so does the small pressure of sunlight hitting the spacecraft.

就连充当探测器电池的那一大块钚散发的热量，也产生了少量的推力。照射到探测器上的太阳光产生的少量压力也一样。

For one thing, the rover has a plutonium battery that should give it far greater longevity than the solar-panelled power systems fitted to previous vehicles.
