(07/20/1961) -- AWAITING ORDERS to proceed to the launching site for Project Mercury's second attempt to launch a man into space, Astronaut Virgil I. 'Gus' Grissom relaxes in a contour chair in the Personal Equipment Room Hangar 'S,' Cape Canaveral, Fla. A parabolic plexiglas mirror on his chest reflects the faces of two fellow Mercury pilots: Walter M. Schirra (left) and M. Scott Carpenter. The mirror, which was not included in the May 5 Shepard flight, will be used to reflect the instrument panel, bringing it into view of the pilot observer camera. MR-4, known as Liberty Bell 7, has been rescheduled for Friday, July 21. (NASA Photo
