毅力号探测车在火星上探测到55次微型闪电事件,可能是沙尘暴静电造成的,这是火星上首次直接发现电气活动的证据。
Perseverance rover detected 55 mini lightning events on Mars, likely from dust storm static, in first direct evidence of electrical activity on the planet.
NASA的毅力号探测车在火星上探测到55次短暂的电放电,或称“迷你闪电”,很可能是由尘魔和风暴中尘埃颗粒产生的静电积累引起的。
NASA’s Perseverance rover has detected 55 brief electrical discharges, or "mini lightning," on Mars, likely caused by static buildup from dust particles swirling in dust devils and storms.
这些信号被漫游者在火星两年期间的麦克风所捕捉,并伴有冲击波和相似的静态火花,证实了关于火星灰尘薄的大气中的电活动的长期理论。
The signals, captured by the rover’s microphone over two Martian years, were accompanied by shockwaves and resemble static sparks, confirming long-held theories about electrical activity in Mars’ dusty, thin atmosphere.
这些排放物虽然在白天是看不见的,但可能对未来的机器人和人类飞行任务构成风险,有可能导致以往的失败,如苏联火星3号着陆器。
Though invisible in daylight, the discharges could pose risks to future robotic and human missions, potentially contributing to past failures like the Soviet Mars 3 lander.
这些结果发表在《自然》上,是此类活动的第一批现场证据,尽管有些科学家告诫说,确认工作有待专门文书进行。
The findings, published in Nature, represent the first in-situ evidence of such activity, though some scientists caution that confirmation awaits dedicated instruments.
