当阿尔忒弥斯1号任务的猎户座飞船在11月21日进行动力飞越月球时，地球上的居民将看到月亮处于月牙期。飞船将接近距离月球表面约130公里的地方，然后前往距离月球约7万公里的遥远逆行轨道。但在11月16日发射时，月亮处于最后四分之一的位置，在午夜后黑暗的凌晨时分接近地平线。这是肯尼迪航天中心上空拍摄的照片，SLS火箭引擎和固体火箭助推器将无人驾驶的猎户座送入太空。在阳光照射的月球近侧明亮边缘出现的不规则条纹是由于火箭通过时产生的压力波改变了相机视线上的折射率造成的。

When the Artemis 1 mission's Orion spacecraft makes its November 21 powered flyby of the Moon, denizens of planet Earth will see the Moon in a waning crescent phase. The spacecraft will approach to within about 130 kilometers of the lunar surface on its way to a distant retrograde orbit some 70,000 kilometers beyond the Moon. But the Moon was at last quarter for the November 16 launch and near the horizon in the dark early hours after midnight. It's captured here in skies over Kennedy Space Center along with the SLS rocket engines and solid rocket boosters lofting the uncrewed Orion to space. Ragged fringes appearing along the bright edge of the sunlit lunar nearside are caused as pressure waves generated by the rocket's passage change the index of refraction along the camera's line of sight.
