He had never ceased to marvel at the Aztec's complexity. Everything about the rocket spoke of the future. She was clearly designed to perform in a time not yet come, at a place not yet known. She would fly, watching the stars, continuously measuring the angle between them, computing her way through the abyss of space. Like a woman she would understand the deep currents within her, the introspective sensing of every force which had an effect upon her life. She would measure gravitation, acceleration and angular velocity with infinite precision. She would count these as units of time, perform complex mathematical equations, translate them into course data, and find her way unerringly across the purple-black night which separated her from her assignation with destiny. She would move with the certainty of a woman fleeing to her lover. Yes, he thought, he would put his life in the lady's hands. He would ride with her on swift wings. But he would be her master. * * * * * His mood changed. He turned from the window thinking it was a hell of a way to spend his last night. Last night on earth, he corrected wryly. He couldn't leave the room, couldn't budge, didn't know where Ann was. No telephone. He went to bed wondering how he'd ever let himself get snookered into the deal. Here he was, young, with a zest for life and a stacked-up gal on the string. And what was he doing about it? Going to the moon, that's what. Going to some damned hell-hole called Arzachel, all because a smooth bird colonel had pitched him a few soft words. Sucker! His lips twisted in a crooked grin. Gotch had seduced him by describing his mission as an "out-of-this-world opportunity." Those had been Gotch's words. Well, that was Arzachel. And pretty quick it would be Adam Crag. Out-of-this-world Crag. Just now the thought wasn't so appealing. * * * * * Sleep didn't come easy. At Gotch's orders he had turned in early, at the unheard hour of seven. Getting to sleep was another matter. It's strange, he thought, he didn't have any of the feelings Doc Weldon, the psychiatrist, had warned him of. He wasn't nervous, wasn't afraid. Yet before another sun had set he'd be driving the Aztec up from earth, into the loneliness of space, to a bleak crater named Arzachel. He would face the dangers of intense cosmic radiation, chance meteor swarms, and human errors in calculation which could spell disaster. It would be the first step in the world race for control of the Solar System--a crucial race with the small nations of the world watching for the winner. Watching and waiting to see which way to lean.
