在这张太空快照中，8亿人即将消失。拍摄于11月21日，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，这是出站的猎户座飞船上的外部摄像机拍摄的。“猎户座”号正在进行一次动力飞行，这次飞行距离月球表面不到130公里。在飞越机动中获得的速度将用于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，因为航天器将以与月球绕地球轨道相反的方向运行。猎户座将于11月25日星期五进入遥远的逆行轨道。11月28日星期一，绕月飞行的“猎户座”飞船将到达离地球最远的距离（40多万公里），超过阿波罗13号创造的人类太空探索最远距离航天器的记录。

ght billion people are about to disappear in this snapshot from space. Taken on November 21, the sixth day of the Artemis 1 mission, their home world is setting behind the Moon's bright edge as viewed by an external camera on the outbound Orion spacecraft. The Orion was headed for a powered flyby that took it to within 130 kilometers of the lunar surface. Velocity gained in the flyby maneuver will be 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 will orbit in the opposite direction of the Moon's orbit around planet Earth. Orion will enter its distant retrograde orbit on Friday, November 25. Swinging around the Moon, Orion will reach a maximum distance (just over 400,000 kilometers) from Earth on Monday November 28 exceeding a record set by Apollo 13 for most distant spacecraft designed for human space exploration.
