Ley, Willy (October 1968). "The Orbit of Explorer-1". For Your Information. Galaxy Science Fiction. Vol. 27, no. 3. pp. 93-102. The original estimate of the lifetime of Explorer-1, made a week or so after firing, was three years. It has been orbiting for ten years by now and the estimate of its remaining lifetime is again three years, but this time surrounded by careful explanations about the factors we don't know.
