OTD In Space – October. 4: Sputnik 1 Becomes 1st Human-Made Satellite to Orbit The Earth

On Oct. 4, 1957, the ******* Union launched Sputnik 1, the satellite that started the Space Race. Sputnik 1 was the first human-made object to orbit the Earth, and it set off a wave of ***** and anxiety across the U.S. now known as the “Sputnik crisis.” Sputnik was a metal sphere roughly 2 feet (58 cm) in diameter with four long radio antennas. These antennas transmitted little beeping pulses down to Earth that even ******** radio operators could hear. The satellite spent 21 days in orbit before it burned up in Earth’s atmosphere.
