AUG 2 4 1989 STANFORD UNIVERSITY WHAS GONE BEFORE HERE NO MAN A History of Apollo Lunar Exploration Missions "The Hammer and the Feather" (48" x 372", acrylic on masonite) Copyright© 1986 by Alan Bean. Used by permission. Apollo 15 commander David R. Scott confirms Galileo's hypothesis that in the absence of air resistance all objects fall with the same velocity. A geologic hammer in Scott's right hand and a falcon feather in his left hand reached the surface of the moon at the same time (see chapter 13). The demonstration was performed before the television camera on the lunar roving vehicle, and no photographs were made. |
