"50 Years of Spaceflight"Today marks the 50th anniversary of the launch of
Sputnik 1 -- a small beeping sphere (about the size of a basketball) with four long antennas. On October 2, 1957, it became the first artificial satellite to orbit the Earth, ushering in the Space Age, and launching a race to the moon between the United States and the former Soviet Union.
