Circus star G. Hugo Zacchini, famous for 30 years as "The Human Cannonball", prepares to climb into the mouth of his cannon during his act in a circus at Palisades Park, N.J., April 11, 1958. Zacchini, who is shot into space twice a day, now is billed as "The Human Satellite." The altered billing reflects his new aim in life - a trip in a rocket. Zacchini is convinced that only a cannon man, used to looking upon life as a bore, is mentally and physically equipped for a space journey.
