60 years ago...

The Sputnik rocket was launched on 4 October 1957 at 19:28:34 UTC. It was the first artificial Earth satellite.

Sputnik 1 (PS-1, literally the Simpliest Satellite) was launched during the International Geophysical Year from Site No.1/5, now the Baikonur Cosmodrome.

The satellite travelled at about 29,000 kilometres per hour (18,000 mph; 8,100 m/s), taking 96.2 minutes to complete each orbit. It transmitted on 20.005 and 40.002 MHz, which were monitored by amateur radio operators throughout the world.


The signals continued for 21 days until the transmitter batteries ran out on 26 October 1957. Sputnik burned up on 4 January 1958 while reentering Earth's atmosphere, after three months, 1440 completed orbits of the Earth, and a distance travelled of about 70 million km (43 million mi).



The success of Sputnik 1 seemed to have changed minds around the world regarding a shift in power to the Soviets.
