在这张摄于2022年11月21日的太空快照中，80亿人即将消失。在阿尔忒弥斯1号任务的第六天，他们的家园正在月球明亮的边缘后面，这是由出站的猎户座飞船上的外部摄像机拍摄的。“猎户座”号将进行一次动力飞越，距离月球表面不到130公里。在飞越机动中获得的速度被用来到达一个遥远的绕月逆行轨道。这个轨道被认为是遥远的，因为它距离月球还有92000公里，而且是逆行的，因为航天器的轨道与月球绕地球轨道的方向相反。11月25日，猎户座进入了遥远的逆行轨道。11月28日，“猎户座”号绕月球飞行，到达了距离地球的最大距离（40多万公里），超过了阿波罗13号为人类太空探索设计的最远距离航天器所创造的记录。“阿尔忒弥斯2号”任务将搭载4名宇航员绕月并返回，计划于2025年9月前发射。

ght 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. Orion entered its distant retrograde orbit on November 25. Swinging around the Moon, Orion reached a maximum distance (just over 400,000 kilometers) from Earth on 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 scheduled to launch no earlier than September 2025.
