LRO, Now in 13th Year of Operation, to Image Long March 3C Impact Site on Moon Far Side
First space debris to strike Moon, likely upper stage of LM-3C used to deliver Chang’e-5 T1 to lunar free return trajectory, will “use its cameras to attempt to identify the impact site”; LRO 20x165km eccentric polar selenocentric orbit is calibrated to reach perilune over the Moon South Pole (now pinpointed to “halfway between 10 and 11 o’clock” of an imaginary clock superimposed over Shackleton Crater), requiring “weeks to months” to achieve favorable conditions; Impact may be visible in Release 50C (15 June) or 51A (15 July)
