   Explanation: When the [5]Artemis 1 mission's Orion spacecraft makes its
   November 21 powered flyby of the Moon, [6]denizens of planet Earth will
   see the Moon in a [7]waning crescent phase. The spacecraft will
   approach to within about 130 kilometers of the lunar surface on its way
   to a [8]distant retrograde orbit some 70,000 kilometers beyond the
   Moon. But the Moon was at last quarter for the November 16 launch and
   [9]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 [10]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 [11]camera's line of
   sight.
