On the anniversary of Marconi's first transatlantic radio signal, the U.S. military launched the first privately built satellite into orbit around the Earth. OSCAR1 - short for Orbiting Satellite Carrying Amateur Radio - hitched a ride aboard a Discoverer satellite that was launched into orbit by a U.S. military Thor-Agena rocket. The payload orbited the Earth for 22 days sending the message "Hi" by Morse code to approximately 300,000 amateur radio operators tracking OSCAR1.
