In February he issued a waming that they would pass within a kilometer of one another. He was right. On Feb. 10, Motorola lost track of Iridium’s signal. Over the next few days, Kelso and others surmised (推测) that what many had feared for years had finally come to pass: two intact (完好无损的) satellites had collided head on.
