“But it wasn't Neil or Buzz that had interested her, or even the moon itself. She had been attracted to the missions' most unsung hero: Michael Collins, alone in Columbia, drifting around the moon in exquisite solitary splendor while Buzz and Neil had gone about the terrestrial work of putting down a plaque, erecting a flag, and gathering rocks. Every two hours Michael Collins had gone out of radio contact for forty-eight minutes when the moon stood between himself and Earth, and during those minutes he was the most alone person in the history of people. Helen still liked to think about that. That had always been her dream: space, not a location with it, just space.”
