Although stars would not normally be visible to the naked eye during daylight, whether from the Earth, the Moon, or on orbit, the planet Venus (which is much brighter than any of the stars) was actually recorded on film by astronaut Alan Shepard at the conclusion of his second extravehicular activity, during the Apollo 14 mission. Shepard was preparing to ascend the ladder to re-enter the lunar module Antares, when he likely noticed Venus shining brightly next to the crescent Earth. He made a series of photographs with his chest-mounted Hasselblad camera, likely all at 1/250th second exposure, and differing f-stops. Owing to its position closer to the Sun and its complete coverage by clouds, Venus has a higher surface brightness than Earth, and is indeed visible to the unaided eye in broad daylight from Earth, given a sufficiently transparent sky. It would have been plainly visible to Shepard in the lunar sky, and easily recorded on film. For a complete explanation, consult the "Images" section of the Apollo 14 Lunar Surface Journal.[5]
In the Apollo 11 press conference, Neil Armstrong states that he was "never able to see stars from the lunar surface or on the daylight side of the moon by eye" [6] Stars were visible with the naked eye only when they were in the shadow of the Moon. All of the landings were in daylight.[7]
