“Very well, Corbett,” said Strong. “I’m going to make as much speed as possible to get these people on Mars. The crew of the Lady Venus will take over the radar and power decks.”
“OK, sir, and spaceman’s luck!” said Tom. “We’ll see you on Mars!”
Tom stood beside the crystal port on the control deck and watched the rocket cruiser Polaris’ stern glow red from her jets, and then quickly disappear into the vastness of space, visible only as a white blip on the radar scanner.
“Get me a course to Mars, Roger,” said Tom. “Astro, stand by to blast off with as much speed as you can safely get out of this old wagon, and stand by for Mars!”
The two cadets quickly reported their departments ready, and following the course Roger plotted, Astro soon had the Lady Venus blasting through space, heading for Mars!
Mars, fourth planet in order from the Sun, loomed like a giant red gem against a perfect backdrop of deep-black space. The Lady Venus, rocketing through the inky blackness, a dull red glow from her three remaining rockets, blasted steadily ahead to the planet that was crisscrossed with wide spacious canals.
“Last time I was on Mars,” said Astro to Tom and Roger over a cup of tea, “was about two years ago. I was bucking rockets on an old tub called the Space Plunger. It was on a shuttle run from the Martian south pole to Venusport, hauling vegetables. What a life! Burning up on Venus and then freezing half to death at the south pole on Mars.” Astro shook his head as the vivid memory took him back for a moment.
“From what I hear,” said Tom, “there isn’t much to see but the few cities, the mountains, the deserts and the canals.”
“Yeah,” commented Roger, “big deal! Rocket into the wild depths of space and see the greatest hunk of wasteland in the universe!”
The three boys were silent, listening to the steady hum of the rockets, driving them forward toward Mars. For four days they had traveled on the Lady Venus, enjoying the many luxuries found on the passenger ship. Now, with their destination only a few hours away, they were having a light snack before making a touchdown on Mars.
“You know,” said Tom quietly, “I’ve been thinking. As far back as the twentieth century, Earthmen have wanted to get to Mars. And finally they did. And what have they found? Nothing but a planet full of dry sand, a few canals and dwarf mountains.”
“That’s exactly what I’ve been saying!” said Roger. “The only man who ever got anything out of all this was the first man to make it to Mars and return. He got the name, the glory, and a paragraph in a history book! And after that, nothing!” He got up and climbed the ladder to the radar deck, leaving Astro and Tom alone.
Suddenly the ship lurched to one side.
“What’s that?” cried Tom.
A bell began to ring. Then another—and then three more. Finally the entire ship was vibrating with the clanging of emergency bells.
Astro made a diving leap for the ladder leading down to the power deck, with Tom lunging for the control board.
Quickly Tom glanced about the huge board with its many different gauges and dials, searching for the one that would indicate the trouble. His eye spotted a huge gauge. A small light beside it flashed off and on. “By the moons of Jupiter, we’ve run out of reactant fuel!”
“Tom!—Tom!” shouted Astro from the power deck. “We’re smack out of reactant feed!”
“Isn’t there any left at all?” asked Tom. “Not even enough to get us into Marsopolis?”
“We haven’t enough left to keep the generator going!” said Astro. “Everything, including the lights and the teleceiver, will go any minute!”
“Then we can’t change course!”
“Right,” drawled Roger. “And if we can’t change course, the one we’re on now will take us straight into Mars’s gravity and we crash!”
“Send out an emergency call right away, Roger,” said Tom.
“Can’t, spaceboy,” replied Roger in his lazy drawl. “Not enough juice to call for help. Or haven’t you noticed you’re standing in the dark?”
“But how—how could this happen?” asked Tom, puzzled. “We were only going at half speed and using just three rockets!”
“When we got rid of that hot tube back in space,” explained Astro grimly, “we dumped the main reactant mass. There isn’t a thing we can do!”
“We’ve got one choice,” said Tom hollowly. “We can either pile out now, in space suits and use the jet boat, and hope for someone to pick us up before the oxygen gives out, or we can ride this space wagon right on in. Make up your minds quick, we’re already inside Mars’s gravity pull!”
There was a pause, then Astro’s voice filled the control deck. “I’ll ride this baby right to the bottom. If I’m going to splash in, I’ll take it on solid ground, even if it is Mars and not Venus. I don’t want to wash out in space!”
“That goes for me, too,” said Roger.
“OK,” said Tom. “Here we go. Just keep your fingers crossed that we hit the desert instead of the mountains, or we’ll be smeared across those rocks like applesauce. Spaceman’s luck, fellas!”
“Spaceman’s luck, both of you,” said Astro.
“Just plain ordinary luck,” commented Roger, “and plenty of it!”
The three boys quickly strapped themselves into acceleration seats, with Tom hooking up an emergency relay switch that he could hold in his hand. He hoped he would remain conscious long enough to throw the switch and start the water sprinkler in case the ship caught fire.
The Lady Venus flashed into the thin atmosphere from the void of space and the three cadets imagined that they could hear the shriek of the ship as it cut through the thin air. Tom figured his speed rapidly, and counting on the thinness of the atmosphere, he estimated that it would take eleven seconds for the ship to crash. He began to count.
“… One—two—three—four—five—” he thought briefly
