Orion and the Ocean of Storms
Image Credit: NASA, Artemis 1
Explanation: On December 5, 2022, a camera on board the uncrewed Orion spacecraft captured this view as Orion approached its return powered flyby of the Moon. Beyond one of Orion’s extended solar arrays lies dark, smooth, terrain along the western edge of the Oceanus Procellarum. Prominent on the lunar nearside Oceanus Procellarum, the Ocean of Storms, is the largest of the Moon’s lava-flooded maria. The lunar terminator, the shadow line between lunar night and day, runs along the left of this frame. The 41 kilometer diameter crater Marius is top center, with ray crater Kepler peeking in at the edge, just right of the solar array wing. Kepler’s bright rays extend to the north and west, reaching the dark-floored Marius. By December 11, 2022 the Orion spacecraft had returned to its home world. The historic Artemis 1 mission ended with Orion’s successful splashdown in planet Earth’s water-flooded Pacific Ocean.

猎户座与风暴之洋
影像提供: NASA, Artemis 1
说明: 2022年12月5日，无人驾驶的猎户座飞船上摄影机拍摄到这一景象，当时猎户座飞船正接近其返回月球的动力飞掠轨道。在猎户座飞船伸展的太阳能板之外，是位于西缘黑暗而平滑的地形。著名的风暴洋位于月球近地侧，是月球上最大的一个熔岩淹没的月海。月球的晨昏线，即月球夜晚与白昼的分界线，沿着画面的左侧延伸。直径41公里的马吕斯坑位于画面上方中央，而克卜勒环形山则在太阳能板翼的右侧边缘隐约可见。克卜勒环形山的明亮射纹向北和向西延伸，直到底部黑暗的马吕斯坑。2022年12月11日，猎户座飞船已返回它的家园。历史性的阿尔忒弥斯1号任务以猎户座飞船成功溅落在地球被海水淹没的太平洋中而告终。
