Sputnik Anniversary

Fifty years ago, a little beeping ball stunned the world. Sputnik 1, launched October 4, 1957, was not large, weighing in at under 200 pounds. It was not very durable, lasting only 22 days in orbit before burning up on re-entry. However, that first artificial satellite set the stage for many more to follow and marked the dawn of the space age. Join Ira Flatow in this hour of Science Friday for a look back at Sputnik and its effects on science, education, and the way we look at the world.
