文章介绍了中国成为首个实现月球背面着陆的国家,阐述了 “嫦娥四号” 着陆的挑战、月球背面的研究价值,以及此次探测对中国未来月球基地计划的意义。
China has become the first country to land a spacecraft on the far side of the moon.
中国已成为首个在月球背面着陆航天器的国家。
The unmanned Chang’e-4 probe (探测器) — the name was inspired by an ancient Chinese moon goddess touched down last week in the South Pole-Aitken basin. Landing on the moon’s far side is extremely challenging. Because the moon’s body blocks direct radio communication with a probe, China first had to put a satellite in orbit above the moon in a spot where it could send signals to the spacecraft and to Earth.
上周,无人探测器“嫦娥四号”(其命名灵感源自中国古代的一位月神)在南极-艾特肯盆地着陆。在月球背面着陆极具挑战性。由于月球本身会阻挡与探测器之间的直接无线电通信,中国首先必须在月球上方的一个位置发射一颗卫星进入轨道,该位置能够向航天器和地球发送信号。
The far side of the moon is of particular interest to scientists because it has a lot of deep craters (环形山),more so than the familiar near side. Chinese researchers hope to use the instruments onboard Chang’e-4 to find and study areas of the South Pole-Aitken basin. "
月球背面尤其令科学家感兴趣,因为它有许多深环形山,比我们熟悉的月球正面还要多。中国研究人员希望利用“嫦娥四号”上搭载的仪器来寻找并研究南极 - 艾特肯盆地的区域。“
This really excites scientists," Carle Pieters, a scientist at Brown University, says, "because it means we have the chance to obtain information about how the moon is constructed" Data about the moon’s composition, such as how much ice and other treasures it contains, could help China decide whether its plans for a future lunar (月球的) base are practical.
这着实让科学家们兴奋不已,”布朗大学的科学家卡尔·皮特斯说道,“因为这意味着我们有机会获取有关月球构造的信息。”有关月球成分的数据,比如它含有多少冰以及其他资源,能够帮助中国确定其未来月球基地计划是否可行。
