Buzz Aldrin stands near Eagle ’s right footpad—with its sixty-eight-inch lunar surface sensing probe extended—in NASA’s iconic image, No. AS11-40-5903. This photo, taken early in the EVA, looks west-southwest. Aldrin may be consulting the checklist on the wrist cover of his left glove. Neil Armstrong and the LM are reflected in his EVA visor, and modern photo analysis has shown that the tiny white dot near the top of his visor is very likely a reflection of Earth. The red knob near Aldrin’s navel, called the red apple, would start a thirty-minute emergency oxygen flow when pulled. Armstrong’s framing cut off the white VHF communication antenna, which extended from the top of Aldrin’s emergency oxygen purge supply unit behind his helmet and is usually not evident in photographs. A black background is commonly added to the top of the photo to provide better visual balance.
