First privately-built satellite

In 1961, the first satellite built by private citizens was put in to orbit. A Thor-Agena rocket, launched to deploy a militaryDiscoverer-36 satellite, also carried the 10-lb OSCAR I . The Orbiting Satellite Carrying Amateur Radio was deployed in low orbit, just above Earth's atmosphere, and it began transmitting "HI" in Morse code,10 times a minute. It was the 60th anniversary of Marconi's first transatlantic radio transmission, and little more than four years since Russia launched Sputnik on 4 Oct 1957. OSCAR 1 was designed and hand-built for $63 by California radio amateurs. The battery powered a 140-mW transmitter on 144.983 MHz, transmitting HI in Morse code for 22 days, for 312 orbits until 1 Jan 1962 when its non-rechargeable battery failed. It burned up in the atmosphere on 31 Jan 1962.«
