Remembering Sputnik 1: 52nd anniversary

We have come so far as 52 years after the launch of – Sputnik I. It’s the world’s first artificial satellite, about the size of a beach ball (58cm or 22.8inches in diameter), weighed only 83.6 kg. or 183.9 pounds, and took about 98 minutes to orbit the Earth on its elliptical path. This single launch managed to put the stepping stone to many new political, military, technology and scientific developments to come. This was the Dawn of Space Age!

Some memorable images...

This metal arming key is the last remaining piece of the first Sputnik satellite. It prevented contact between the batteries and the transmitter prior to launch. Currently on display at the National Air and Space Museum.
