Stand by for Mars! by Carey Rockwell (desktop ebook reader TXT) 📕

giving Roger a few pointers on control-deck operation. And one night I found Manning giving Astro a lecture in compression ratios. Of course, Manning's way of talking is a way that would confuse the Venusian more than it would help him, but at least they weren't snarling at each other."

"Hmm," Walters nodded. "Sounds hopeful, but still not conclusive. After all, they have to help each other in the manuals. If one member of the unit fails, it will reflect on the marks of the other two and they might be washed out too. Even the deadliest enemies will unite to save their lives."

"Perhaps, sir," replied Strong. "But we're not dealing with deadly enemies now. These are three boys, with three distinct personalities who've been lumped together in strange surroundings. It takes time and patience to make a team that will last for years."

"You may have the patience, Steve, but the Academy hasn't the time." Commander Walters was suddenly curt. "When does Unit 42-D take its manuals?"

"This afternoon, sir," replied Strong. "I'm on my way over to the examination hall right now."

"Very well. I won't take any action yet. I'll wait for the results of the tests. Perhaps they will solve both our problems. See you later, Steve." Turning abruptly, Commander Walters stepped off the slidewalk onto the steps of the Administration Building and rapidly disappeared from view.

Left alone, Strong pondered the commander's parting statement. The implication was clear. If the unit failed to make a grade high enough to warrant the trouble it took keeping it together, it would be broken up. Or even worse, one or more of the boys would be dismissed from the Academy.

A few minutes later Strong arrived in the examination hall, a large, barren room with a small door in each of the three walls other than the one containing the entrance. Tom Corbett was waiting in the center of the hall and saluted smartly as Strong approached.

"Cadet Corbett reporting for manual examination, sir!"

"Stand easy, Corbett," replied Strong, returning the salute. "This is going to be a rough one. Are you fully prepared?"

"I believe so, sir." Tom's voice wasn't too steady.

A fleeting smile passed over Strong's lips, then he continued. "You'll take the control-deck examination first. Manning will be next on the radar bridge and Astro last on the power deck."

"They'll be here according to schedule, sir."

"Very well. Follow me."

Strong walked quickly to the small door in the left wall, Tom staying a respectful step behind. When they reached the door, the officer pressed a button in the wall beside it and the door slid open.

"All right, Corbett. Inside." Strong nodded toward the interior of the room.

The boy stepped in quickly, then stopped in amazement. All around him was a maze of instruments and controls. And in the center, twin pilot's chairs.

"Captain Strong!" Tom was so surprised that he could hardly get the words out. "It's—it's a real control deck!"

Strong smiled. "As real as we can make it, Corbett, without allowing the building to blast off." He gestured toward the pilot's chairs. "Take your place and strap in."

"Yes, sir." His eyes still wide with wonder, Tom stepped over to the indicated chair and Strong followed him, leaning casually against the other.

He watched the young cadet nervously adjust his seat strap and put a comforting hand on his shoulder. "Nervous, Corbett?"

"Yes, sir—just a little," replied Tom.

"Don't worry," said Strong. "You should have seen the way I came into this room fifteen years ago. My cadet officer had to help me into the control pilot's seat."

Tom managed a fleeting smile.

"Now, Corbett"—Strong's voice became businesslike—"as you know, these manual tests are the last tests before actually blasting off. In the past weeks, you cadets have been subjected to every possible examination, to discover any flaw in your work that might later crop up in space. This manual operations test of the control board, like Manning's on the radar bridge and Astro's on the power deck, is designed to test you under simulated space conditions. If you pass this test, your next step is real space."

"Yes, sir."

"I warn you, it isn't easy. And if you fail, you personally will wash out, and if other members of the unit do not get a high enough mark to average out to a passing grade for all of you, you fail as a unit."

"I understand, sir," said Tom.

"All right, then we'll begin. Your crew is aboard, the air lock is closed. What is the first thing you do?"

"Adjust the air circulating system to ensure standard Earth conditions."

"How do you do that?"

"By pressing this button which will activate the servo units. They automatically keep the circulating pumps in operation, based on thermostatic readings from the main gauge." Tom pointed to a black clock face, with a luminous white hand and numbers.

"All right, carry on," said Strong.

Tom reached over the huge control board that extended around him for some two feet on three sides. He placed a nervous finger on a small button, waited for the gauge below to register with a swing of the hand, and then released it. "All pressures steady, sir."

"What next?"

"Check the crew, sir—all departments—" replied Tom.

"Carry on," said Strong.

Tom reached out and pulled a microphone toward him.

"All hands! Station check!" said Tom, and then was startled to hear a metallic voice answer him.

"Power deck, ready for blast-off!" And then another voice: "Radar deck, ready for blast-off!"

Tom leaned back in the pilot's seat and turned to the captain. "All stations ready, sir."

"Good! What next?" asked Strong.

"Ask spaceport tower for blast-off clearance—"

Strong nodded. Tom turned back to the microphone, and without looking, punched a button in front of him.

"Rocket cruiser—" He paused and turned back to Strong. "What name do I give, sir?"

Strong smiled. "Noah's Ark—"

"Rocket cruiser Noah's Ark to spaceport control! Request blast-off clearance and orbit."

Once again a thin metallic voice answered him and gave the necessary instructions.

On and on, through every possible command, condition or decision that would be placed in front of him, Tom guided his imaginary ship on its imaginary flight through space. For two hours he pushed buttons, snapped switches and jockeyed controls. He gave orders and received them from the thin metallic voices. They answered him with such accuracy, and sometimes with seeming hesitation, that Tom found it difficult to believe that they were only electronically controlled recording devices. Once, when supposedly blasting through space at three-quarters space speed, he received a warning from the radar bridge of an approaching asteroid. He asked for a course change, but in reply received only static. Believing the recording to have broken down, he turned inquiringly to Captain Strong, but received only a blank stare in return. Tom hesitated for a split second, then turned back to the controls. He quickly flipped the teleceiver button on and began plotting the course of the approaching asteroid, ignoring for the moment his other duties on the control deck. When he had finished, he gave the course shift to the power deck and ordered a blast on the starboard jet. He waited for the course change, saw it register on the gauges in front of him, then continued his work.

Strong suddenly leaned over and clapped him on the back enthusiastically.

"Good work, Corbett. That broken recording was put there intentionally to trap you. Not one cadet in twenty would have had the presence of mind you showed in plotting the course of that asteroid yourself."

"Thank you, sir," stammered Tom.

"That's all—the test is over. Return to your quarters." He came over and laid a hand on Tom's shoulder. "And don't worry, Corbett. While it isn't customary to tell a cadet, I think you deserve it. You've passed with a perfect score!"

"I have, sir? You mean—I really passed?"

"Next step is Manning," said Strong. "You've done as much as one cadet can do."

"Thank you, sir"—Tom could only repeat it over and over—"thank you, sir—thank you."

Dazed, he saluted his superior and turned to the door. Two hours in the pilot's chair had made him dizzy. But he was happy.

Five minutes later he slammed back the sliding door and entered the quarters of 42-D with a lusty shout.

"Meet Space Cadet Corbett—an Earthworm who's just passed his control-deck manual operations exam!"

Astro looked up from a book of tables on astrogation and gave Tom a wan smile.

"Congratulations, Tom," he said, and turned back to his book, adding bitterly, "but if I don't get these tables down by this afternoon for my power-deck manual, you're sunk."

"Say—what's going on here?" asked Tom. "Where's Roger? Didn't he help you with them?"

"He left. Said he had to see someone before taking his radar-bridge manual. He helped me a little. But when I'd ask him a question, he'd just rattle the answer off so fast—well, I just couldn't follow him."

Suddenly slamming the book shut, he got up. "Me and these tables"—he indicated the book—"just don't mix!"

"What's the trouble?"

"Ah—I can get the easy ones about astrogation. They're simple. But it's the ones where I have to combine it with the power deck."

"Well—I mean—what specifically?" asked Tom softly.

"For instance, I've got to find the ratio for compression on the main firing tubes, using a given amount of fuel, heading for a given destination, and taking a given time for the passage."

"But that's control-deck operations—as well as astrogation and power!" exclaimed Tom.

"Yeah—I know," answered Astro, "but I've still got to be able to do it. If anything happened to you two guys and I didn't know how to get you home, then what?"

Tom hesitated. Astro was right. Each member of the unit had to depend on the other in any emergency. And if one of them failed ...? Tom saw why the ground manuals were so important now.

"Look," offered Tom. "Suppose we go over the whole thing again together. Maybe you're fouled up on the basic concept."

Tom grabbed a chair, hitched it close to the desk and pulled Astro down beside him. He opened the book and began studying the problem.

"Now look—you have twenty-two tons of fuel—and considering the position of your ship in space—"

As the two boys, their shoulders hunched over the table, began reviewing the table of ratios, across the quadrangle in the examination hall Roger Manning stood in a replica of a rocket ship's radar bridge and faced Captain Strong.

"Cadet Manning reporting for manual examination, sir." Roger brought up his arm in a crisp salute to Captain Strong, who returned it casually.

"Stand easy, Manning," replied Strong. "Do you recognize this room?"

"Yes, sir. It's a mock-up of a radar bridge."

"A workable mock-up, cadet!" Strong was vaguely irritated by Roger's nonchalance in accepting a situation that Tom had marveled at. "You will take your manuals here!"

"Yes, sir."

"On these tests you will be timed for both efficiency and speed and you'll use all the tables, charts and astrogation equipment that you'd find in a spaceship. Your problems are purely mathematical. There are no decisions to make. Just use your head."

Strong handed Roger several sheets of paper containing written problems. Roger shuffled them around in his fingers, giving each a quick glance.

"You may begin any time you are ready, Manning," said Strong.

"I'm ready now, sir," replied Roger calmly. He turned to the swivel chair located between the huge communications board, the adjustable chart table and the astrogation prism. Directly in front of him was the huge radar scanner, and to one side and overhead was a tube mounted on a swivel joint that looked like a small telescope, but which was actually an astrogation prism for taking sights on the celestial bodies in space.

Roger concentrated on the first problem.

" ... you are now in the northwest quadrant of Mars, chart M, area twenty-eight. You have been notified by the control deck that it has been necessary to jettison three quarters of your fuel supply. For the last five hundred and seventy-nine seconds you have been blasting
