It is claimed that the Superschmidt Telescope at Sacremento Peak photographed the trajectory with a rotating shutter. These little metal pellets would therefore be the first objects to be shot into interplanetary space, months before the first launch to escape velocity (Luna 1, January 1959). But also see August 1957 nuclear test that may have blasted a manhole cover to escape velocity.
