Launched on October 4, 1957, Sputnik 1 was the first craft in orbit around the earth. Named from the Russian phrase for "traveling companion of the world" (Sputnik Zemli), it was a small satellite measuring only 58 sm across It circled the earth once 92.6 minutes and transmitted information about the earth’s atmosphere. After 57 days in space, it re­entered the atmosphere and was destroyed.
This historic launch began an era of intensive space programmers by both the Soviet Union and the United States. In the next three decades, hundreds of probes, satellites, and other missions were to follow Sputnik on the quest to explore: both the wonders and the practical potential of space.
