The Colonel continued grimly. "Radar indicates this is a different kind of rocket. Its rate of climb ... its trajectory ... indicates it's manned. Now it's a race."
Crag thought a moment. "Any sign of a drone with it?"
"No, that's the surprising part, if this is a full-scale attempt at establishing a moon base. And we believe it is."
Crag asked sharply. "It couldn't be their atom-powered job?" The possibility filled him with alarm.
"Positively not. We've got our finger squarely on that one and it's a good year from launch-date. No, this is a conventional rocket ... perhaps more advanced than we had believed...." His voice dropped off. "We'll keep you posted," he added after a minute.
"Roger." Crag sighed. He removed the earphone reflectively. He wouldn't tell the others yet. Now that they were in space maybe ... just maybe ... he could find time to catch his breath. Damn, they hadn't anticipated all this during indoctrination. The intercept-missile ... time bomb ... possible traitor in the crew. What more could go wrong? For just a second he felt an intense hostility toward Gotch. An Air Force full of pilots and he had to pick him—and he wasn't even in the Air Force at the time. Lord, he should have contented himself with jockeying a jet airliner on some nice quiet hop. Like between L. A. and Pearl ... with a girl at each end of the run.
He thought wistfully about the prospect while he made a routine check of the instruments. Cabin pressure normal ... temperature 78 degrees F. ... nothing alarming in the radiation and meteor impact readings. Carbon dioxide content normal. Things might get routine after all, he thought moodily. Except for one thing. The new rocket flashing skyward from east of the Caspian. One thing he was sure of. It spelled trouble.
CHAPTER 6
The U. S. Navy's Space Scan Radar Station No. 5 picked up the new rocket before it was fairly into space. It clung to it with an electromagnetic train, bleeding it of data. The information was fed into computers, digested, analyzed and transferred to Alpine Base, and thence telemetered to the Aztec where it appeared as a pip on the analog display. The grid had automatically adjusted to a 500-mile scale with the positions of the intruder and Aztec separated by almost the width of the instrument face. The Aztec seemed to have a clear edge in the race for the moon. Prochaska became aware of the newcomer but refrained from questions, nor did Crag volunteer any information.
