In the late Fifties, two ingenious amateur radio operators, the brothers Achille and Giovanni Battista Judica Cordiglia, set up a full-fledged space listening center in Turin, using recycled technologies they themselves had adapted. So began a story the documentary describes through the live contributions of the Cordiglia brothers, their amazing archive footage (videos and recordings) and the people that witnessed their accomplishments in Italy and the United States. On October 4th, 1957, the Cordiglias claim they were the first ones to capture the sounds from Sputnik 1. After this remarkable success, they went on to intercept the major space missions launched by the USA and the USSR, including a few secret ones that might have cost the Sovietic astronauts their lives. While the two radio amateur operators - the fore-runners of present-day hackers - were recording all of that, the Cold War was raging. The two superpowers were racing to reach space first and tried to control all information and propaganda. This incredible story reached its apex in 1962, when the brothers won a trip to NASA after participating in Mike Bongiorno’s quiz show "La fiera dei sogni".
Space Hackers purposefully offers only the Cordiglias’ viewpoint on the events described, although space exploration scholars are currently questioning their claims as unsubstantiated.
