The Mars rover Spirit, now bogged down in the Red Planets soil, will need all the power it can muster if NASA scientists manage to get it moving again. So if s timely that researchers are getting a handle on why dust that collects on the vehicle's solar panels sticks so stubbornly.rnMartian dust is particularly clingy. This was noticed more than a decade ago when surprisingly large amounts stuck to the wheels of NASA's Sojourner rover. Static electricity was thought to be to blame, but no one could explain-how the particles became charged. Now a team led by Keith Forward of Case Western Reserve University in Cleveland, Ohio, have an answer.

机译：火星漫游者精神，现在陷入了红色星球的土壤，如果美国航空航天局的科学家设法使其重新移动，它将需要它所能聚集的所有力量。因此，如果时机成熟，研究人员就能弄清楚为什么聚集在车辆太阳能电池板上的灰尘会如此顽固地粘着。玛蒂安的灰尘尤为棘手。十多年前，当NASA的“旅居者”漫游者的车轮上出奇地大量附着时，就注意到了这一点。静电被认为是罪魁祸首，但没人能解释-粒子如何带电。现在，由位于俄亥俄州克利夫兰的Case Western Reserve大学的Keith Forward领导的团队有了答案。
