Sputnik 50th anniversary

50 years ago to today, October 4, 1957, the Soviet Union launched a small, beachball-sized sphere into orbit named Sputnik I.

This event inaugurated not only the "space age" but the "communications and information age" as well because Sputnik did more than just placidly orbit the Earth- it sent back information (listen to a .wav file of the telemetry) about its journey.

Sputnik I stayed in orbit for three months until January 4, 1958 when its orbit decayed and it burned up upon re-entry.

It's impact cannot go unnoticed in today's world of cell phones, satellite television, the internet, et al. Take a moment to learn more about it and the world it helped create.
