研究发现小行星撞击38亿年前 创造了巨大的月亮峡谷 协助美国航天局的阿耳特弥斯计划 Study finds asteroid impact 3.8 billion years ago created massive moon canyons, aiding NASA's Artemis program.

最近的一项研究表明 大约38亿年前的小行星撞击 在月球的远方 创造了两个巨大的峡谷 与亚利桑那的大峡谷相似 A recent study reveals that an asteroid impact about 3.8 billion years ago created two massive canyons on the moon's far side, comparable to Arizona's Grand Canyon. 撞击估计为15英里宽,以高速抛出碎片,在10分钟内形成峡谷。 The impact, estimated to be 15 miles wide, ejected debris at high speeds, forming the canyons within 10 minutes. 美国航天局发现这一信息对于其Artemis方案很有价值,该方案旨在将宇航员降落在月球的南极,那里的老岩石仍然完好无损,对月球和地球的起源提供了深入的了解。 NASA finds this information valuable for its Artemis program, aiming to land astronauts at the moon's south pole, where older rocks remain intact, offering insights into the moon's and Earth's origins. 该研究还建议,南极的永久阴影区可能含有对未来月球飞行任务有用的冰块。 The study also suggests that permanent shadow areas at the south pole may contain ice useful for future lunar missions.
