the empty deck. Walking over to one of the jet boats, he saw evidence of Al James's attempts to send out emergency signal messages. He called again. "Hey, Astro—where are you?" Still no answer. He noticed that one of the jet boats was missing. There were three still on the deck, but an empty catapult for the fourth made Tom think that Astro might have repaired the fourth and taken it out in space for a test. The light over the escape hatch indicated that someone had gone out. It was odd, thought Tom, for Astro to go out alone. But then he shrugged, remembering how Astro could lose himself in his work and forget everything but the job at hand. He climbed back to the passenger deck.

When Tom opened the hatch to the main lounge, the [Pg 144]sight that filled his eyes was so funny that, even in the face of danger, he had to laugh. Roger, with his hands clasped behind his back, was down on his knees trying to push a food pellet across the deck with his nose. The whole passenger lounge echoed with hysterical laughter.

Suddenly the laughter was stopped by the sound of the bell over the air-lock hatch. Strong and James had returned to ferry more passengers to the Polaris. Immediately the fun was forgotten and the passengers crowded around for the roll call.

"Where's Astro?" asked Strong, as he reappeared in the lounge.

"He's down on the jet-boat deck, sir, trying to fix another one," replied Tom. "I think he's out testing one now."

"Good," said Strong. "How're they taking it?" He indicated the passengers.

"Roger's been keeping them amused with games and songs, sir," said Tom proudly.

"They'll need it. I don't mind telling you, Corbett," said Strong, "it's a wonder to me this tub hasn't blown up already."

In less than a half hour, the forty passengers and crewmen of the Lady Venus were transferred in alphabetical order to the waiting Polaris. Roger kept up a continual line of patter and jokes and stories, making a fool of himself, but keeping the remaining passengers amused and their minds off the dangers of the rapidly building reaction mass.

"Just one passenger left," said Strong, "with myself and you three. I think we can squeeze five in that jet boat and get off here."

"That's for me," said Roger. "I'm the only man in the whole universe that's ever played to a packed house sitting on top of an atomic bomb!" [Pg 145]

"All right, Barrymore," said Strong, "get aboard!"

"Say," asked Tom, "where's Astro?"

"I don't know," replied Roger. "I thought you went to find him half an hour ago!"

"I did," said Tom, "but when I went to the jet-boat deck, one was missing. So I figured he had fixed one and taken it out for a test."

"Then he's probably outside in space now!" said Strong. Suddenly the Solar Guard captain caught himself. "Wait a minute! How many jet boats were on the deck, Corbett?"

"Three, sir."

"Then Astro is still aboard the ship," said Strong. "He couldn't have taken a boat. James told me he couldn't repeat the message he sent out because he only had the power of three jet boats. One was damaged and left behind at Atom City!"

"By the rings of Saturn," said Roger, "a coupla million miles from home, sitting on an atomic bomb and that big Venusian hick decides to play hide-and-seek!"

"Never mind the cracks," said Strong. "We've got to find him!"

"Captain," said the little man with the round face and glasses who had first spoken to Strong when he came aboard, "just because my name happens to be Zewbriski, and I have to be the very last to get on a jet boat, I don't see why I have to wait any longer. I demand to be taken off this ship immediately! I refuse to risk my life waiting around for some foolish cadet!"

"That foolish cadet, Mr. Zewbriski," said Strong coldly, "is a human being like you and we don't budge until we find him!"

At that moment the bell began to ring, indicating that the outer hatch to the air lock was opening.

"By the craters of Luna," said Tom, "that must be Astro now!" [Pg 146]

"But if it is," said Roger, "how did he get out there?"

From behind them, the hatch to the inner air lock opened and Al James stepped through.

"Captain Strong," he said excitedly, "you've got to come quickly. Some of the crewmen have broken into your arms locker and taken paralo-ray guns. They threaten to leave you here if you don't return to the ship within five minutes. They're afraid the Venus might blow up and damage the Polaris at this close range." The young skipper, his red-brown uniform torn and dirty, looked at the Solar Guard captain with wild-eyed desperation.

"They can't leave us here," whimpered Zewbriski. "We'll all be blown to bits!"

"Shut up!" barked Strong. He turned to Tom and Roger. "I can do one of two things," he said. "I can order you to return to the Polaris now, with James and myself, or you can volunteer to stay behind and search for Astro."

Without looking at Roger, Tom answered, "We'll stay, sir. And we won't have to search for him. I think I know where he is."

"Now that I think about it," replied Strong, "I guess there is only one place he could be."

"Yes, sir," said Tom, "down on the power deck trying to save this wagon! Come on, Roger! Let's get him!" [Pg 147]

CHAPTER 15

"What's the reading on the Geiger counter now?" asked Tom.

Roger looked down at the face of the radioactive measuring device and answered, "She's been dropping for the last five minutes, Tom. Looks like the mass in number three is cooling off. Fourteen hundred and ten now."

"That's not fast enough," said Astro, straightening up from tightening a nut on the lead baffle. "She's still plenty hot. That mass should have been dumped out of the rocket exhaust right away. Now the whole tube control box is so hot with radiation, it'd burn you to a crisp if you opened the hatch."

"Good thing you brought along those tools from the Polaris," said Tom.

"Yeah, greaseball," said Roger, "you used your head for once. Now let's see you use it again and pile out of this hunk of junk!"

"Fifteen hundred on the counter is the danger mark, Roger, and as long as we keep it under that, I'm going to try and save this wagon!" replied Astro.

"Why? To get yourself a Solar Medal?" asked Roger sarcastically.

"What do you think made this tub act up like this, Astro?" asked Tom, ignoring Roger's remark. [Pg 148]

"Using special reactant feed, Tom," replied Astro. "This is a converted chemical burner—with an old-type cooling pump. It's touchy stuff."

"Well, couldn't we drive boron rods into the mass and slow down the reaction?" asked Tom.

"No, Tom," answered Astro, "the control for the rods are inside the tube control box. We can't reach it."

There was a sudden loud ticking from the Geiger counter.

"Astro!" cried Roger. "The mass is building!"

"Here, lemme see!" shouted Astro. He took the instrument in his big hand and watched the clocklike face intently.

" ... fourteen hundred thirty—fourteen hundred fifty—fourteen hundred seventy—" He faced his unit-mates. "Well, that does it. The mass is maintaining a steady reaction without the energizing pumps. It's sustaining itself!"

"But how is that possible?" asked Tom.

"It's one of those freaks, Tom. It's been known to happen before. The fuel is just hot enough to sustain a steady reaction because of its high intensity. Once that baffle worked loose, the mass started wildcatting itself."

"And if it doesn't stop?" asked Roger tensely.

"It'll reach a point where the reaction comes so fast it'll explode!"

"Let's pile out of here!" said Roger.

The three boys made a dash for their space suits and the jet boat. Inside the air lock, they adjusted their oxygen valves and waited for pressure to equalize so they could blast off.

"Blast it," said Astro, "there must be some way to get to that rocket tube and dump that stuff!"

"Impossible, Astro," said Roger. "The release controls are in the control box, and with all that radiation loose, you wouldn't last half a minute!" [Pg 149]

Tom walked over to the valve that would open the outside hatch.

"Wonder how Captain Strong is making out with those tough babies on the Polaris?" asked Tom.

"I don't know," replied Roger, "but anything would be better than sitting around waiting for this thing to blow up!"

"Ah—stop griping," said Astro, "or I'll shove you up a rocket tube and blast you from here all the way back to Atom City!"

"Hey, wait a minute!" shouted Tom. "Astro, remember the time we were on the ground crew as extra duty and we had to overhaul the Polaris?"

"Yeah, why?"

"There was one place you couldn't go. You were too big, so I went in, remember?"

"Yeah, the space between the rocket tubes and the hull of the ship. It was when we were putting in the new tube. So what?"

"So this!" said Tom. "When they converted this tub, they had standard exhausts, so it must have the same layout as the Polaris. Suppose I climb in the main exhaust, between the tube and the outer hull, and cut away the cleats that hold the tube to the ship?"

"Why, then everything would come out in one piece!" Astro's face lit up. "Reactant mass, tube, control box—the works!"

"Say, what are you two guys talking about?" asked Roger.

"Saving a ship, Roger," said Tom. "Dumping the whole assembly of the number-three rocket!"

"Ah—you're space happy!"

"Maybe," said Tom, "but I think it's worth trying. How about it, Astro?"

"O.K. by me, Tom," replied Astro.

"Good. You get the cutting torches rigged, Astro. [Pg 150]Roger, you give him a hand and keep your eye on the counter. Then feed the torches to me when I get inside the tube. I'm going outside to get rid of a bad rocket and save a five-million-credit spaceship!"

Before Astro or Roger could protest, Tom opened the hatch and began to climb out on the steel hull toward the rocket tubes, main exhaust.

His magnetic-soled shoes gripping the smooth steel hull, the cadet made his way aft to the stern of the ship and began the climb down around the huge firing tubes and into the tubes themselves.

"Hey, Astro," he yelled into the spacephone, "I'm inside the tubes. How about those torches?" The cadets had adjusted the wave length so that all could hear what was said.

"Take it easy, spaceboy," said Roger, "I'm leaving the hatch now. You and your fatheaded friend from Venus are so hopped up for getting a Solar Medal—"

"Knock it off, Manning!" said Astro from inside the ship. "And for your information, I don't want a medal. I don't want anything except for you to stop griping!"

Roger reached the end of the ship and began to climb down inside the tube where Tom was waiting for him.

"O.K., spaceboy," said Roger, "here're your cutting torches." He started moving back. "I'll see you around. I don't mind being a little hero for saving people and all that stuff. But not for any ship. And the odds against a big hero staying alive are too big!"

"Roger, wait," shouted Tom. "I'll need...." And then the curly-headed cadet clamped his teeth together and turned back to the task at hand.

He made adjustments on the nozzle of the cutting torch, and then, focusing his chest light, called to Astro.

"O.K., Astro," he said, "shoot me the juice!"

"Coming up, Tom!" answered Astro. "And wait till I [Pg 151]get my hands on that Manning! I'm going to smear that yellow space crawler from one corner of the universe to another!"

"Never mind the talk," snarled Roger, who at the moment was re-entering the tube. "Just get that juice down to this torch and make it fast!"

Tom turned to see Roger crawling back into the tube and adjusting a cutting torch.

"Glad to have you aboard, Roger," said Tom with a smile that Roger could not see in the darkness of the tube. The two boys went to work.

Suddenly the torches came to life. And immediately Tom and Roger began to cut away at the cleats that held the tube lining to the skin of the ship. Steadily, the cadets worked their way up toward the center of the ship, cutting anything that looked as though it might hold the giant tube to the ship.

"Boy," said Tom, "it's getting hot in here!"

From inside the ship, Astro's reassuring voice came back in answer. "You're getting close to the reactant-mass chamber. The last cleat is up by one of the exhaust gratings. Think you can last it?"

"Well, if he can't," snarled Roger, "he's sure to get that medal anyway!" He inched up a little. "Move over, Corbett, I'm skinnier than you are, and I can reach that cleat easier than you can."

Roger slipped past Tom and inched his way toward the last cleat. He pulled his torch up alongside and pulled the trigger. The flame shot out and began eating the steel. In
