THE SIGNALS from space began a little after midnight, local time, an a Friday. They were first picked up in the South Pacific, just westward of the International Date Line. A satellite-watching station on an island named Kalua was the first to receive them, though nobody heard the first four or five minutes. But it is certain that the very first message was picked up and recorded by the monitor instruments. The satellite-tracking unit on Kalua was practically a duplicate of all its fellows. There was the station itself with a vertical antenna outside pointing at the stars. There were various lateral antennae held two feet aboveground by concrete posts. In the instrument room in the building a light burned over a desk, three or four monitor lights glowed dimly to indicate that the self-recording instruments were properly operating, and there was a multiple-channel tape recorder built into the wall. Its twin tape reels turned sedately, winding a brown plastic ribbon from one to the other at a moderate pace.
