Sputnik 1 Orbits the Earth
I didn't comprehend much of the 'space race' back when I was a youngster. In grade school I saw pictures of the Soviet Sputnik satellites and vaguely recall the understanding of them in orbit but I wasn't really much into the Gemini stuff either.
The allure for me didn't come til much later because my early life was predominated by monster movies, Astroboy, superheros, cartoon characters, The Three Stooges, and other such aspects of a lingering childhood fantasy life. The kid stuff controlled my existence for a very long time.

It consisted of a polished metal sphere 23 inches in diameter with four external radio antennas over which radio pulses were broadcast.
Its radio signal was easily detectable by amateur radio operators. The 65° orbital inclination and duration of its orbit placed it's flight path over virtually the entirety of the Earth's population.
Those signals from Sputnik 1 continued for 21 days which corresponded to the life of the transmitter batteries which became depleted on October 26, 1957.
It orbited for three weeks before its batteries died and then orbited silently for two months before it fell back into and burned in the atmosphere on January 4, 1958 after completing 1,440 orbits of the Earth. Thus began the 'space race' between the United States and the Soviet Union as part of the so-called 'cold war'. The launch of Sputnik 1 was marked the start of a new era from a standpoint of international technological, scientific, political, and military developments.
The word "sputnik" is Russian for satellite in the context of astronomy but may also refer to a spouse or traveling companion depending on what is being discussed.
