英文原文:Explanation: Eight billion people are about to disappear in this snapshot from space taken on 2022 November 21. On the sixth day of the Artemis I mission , their home world is setting behind the Moon's bright edge as viewed by an external camera on the outbound Orion spacecraft. Orion was headed for a powered flyby that took it to within 130 kilometers of the lunar surface. Velocity gained in the flyby maneuver was used to reach a distant retrograde orbit around the Moon. That orbit is considered distant because it's another 92,000 kilometers beyond the Moon, and retrograde because the spacecraft orbited in the opposite direction of the Moon's orbit around planet Earth. Swinging around the Moon , Orion reached a maximum distance (just over 400,000 kilometers) from Earth on 2022 November 28, exceeding a record set by Apollo 13 for most distant spacecraft designed for human space exploration . The Artemis II mission , carrying 4 astronauts around the moon and back again, is due to launch as early as February 6. 说明: 八十亿人[3]即将在这张拍摄于2022年11月21日的太空快照[4]中消失。 在阿提米丝一号任务的第六天[5],从即将离开地球的猎户座太空船的外部摄影机[6]拍摄到,他们的家园地球正从月球明亮的边缘后方缓缓落下。 猎户座太空船正准备进行一次动力飞掠,将其带到距月球表面130公里的距离。 飞掠操作中获得的速度被用来进入一个远距逆行轨道[7]环绕月球。 该轨道被认为是远距的,因为它在月球之外92,000公里,逆行是因为太空船的轨道方向与月球绕地球的轨道方向相反。 在环绕月球飞行[8]的过程中,猎户座太空船于2022年11月28日到达了距地球超过400,000公里的最大距离,打破了阿波罗13号最远[9]载人太空船的飞行距离纪录,该任务太空船是为人类太空探索[10]而设计。 阿提米丝二号任务[11],将载着四名太空人环绕月球并返回,最快将于 2 月 6 日发射。。
