Buzz Aldrin had hoped, and briefly expected, that it would be he, and not Neil Armstrong, who would take the first human step on the moon. The astronaut Michael Collins, who manned the control module that orbited the moon while Armstrong and Aldrin walked below, has said of Aldrin that he 'resents not being first on the moon more than he appreciates being second.' On the moon, Armstrong took photos of Aldrin posing, but Aldrin took none of Armstrong doing the same. One of the few photos that shows Neil Armstrong on the moon was taken by Armstrong himself—of his reflection in Aldrin’s helmet, as Aldrin salutes the flag. We are petty and misbehave on Earth; we will be petty and misbehave in space.
