It looks, in old photographs, like something a giant assembled from spare parts. Yet from this stretch of Crimean coast near Yevpatoria, humanity managed some of its first conversations with the other worlds of the solar system, and sent its first deliberate messages to the stars.

Pluton was raised in 1960 as the heart of a deep-space communications center, its purpose to command spacecraft flying to Venus and Mars and to bounce radar off distant planets. The engineering was audacious and thrifty. The complex used at least three ADU-1000 antennas, each an ...

It was not a comfortable memory. Decades later, in 2009, Lovell told The Daily Telegraph that he had developed radiation sickness aft...
