"We"re not in the clear yet!" commented Astro grimly. "It would take a hundred men at least a week to clear away enough of that sand so search parties could recognize it." He glanced toward the horizon. "There isn"t anything but sand here, fellows, sand that stretches for a thousand miles in every direction."
"And we"ve got to walk it," said Tom.
"Either that or sit here and die of thirst," said Roger.
"Any ca.n.a.ls around here, Tom?" asked Astro softly.
"There better be," replied Tom thoughtfully. He turned to Roger. "If you can estimate our position, Roger, I"ll go back inside and see if I can find a chart to plot it on. That way, we might get a direction to start on at least."
Astro glanced up at the pale-blue sky. "It"s going to be a hot day," he said softly, looking out over the flat plain of the desert, "an awful hot day!"

CHAPTER 20
"Got everything we need?" asked Tom.
"Everything we"ll need--and about all we can safely carry without weighing ourselves down too much," answered Roger. "Enough food for a week, the rest of the Martian water, s.p.a.ce goggles to protect our eyes from the sun and emergency lights for each of us."
"Not much to walk a hundred and fifty miles on," offered Astro. "Too bad the sand got in the galley and messed up the rest of that good food."
"We"ll have plenty to get us by--if my calculations are right," said Tom. "One hundred and fifty-four miles to be exact."
"_Exact_ only as far as my sun sight told me," said Roger.
"Do you think it"s right?" asked Tom.
"I"ll answer you this way," Roger replied. "I took that sight six times in a half hour and got a mean average on all of them that came out within a few miles of each other. If I"m wrong, I"m very wrong, but if I"m right, we"re within three to five miles of the position I gave you."
"That"s good enough for me," said Astro. "If we"re going out there"--he pointed toward the desert--"instead of sitting around here waiting for Strong or someone to show up, then I"d just as soon go now!"
"Wait a minute, fellas. Let"s get this straight," said Tom. "We"re all agreed that the odds on Captain Strong"s showing up here before our water runs out are too great to risk it, and that we"ll try to reach the nearest ca.n.a.l. The most important thing in this place is water. If we stay and the water we have runs out, we"re done for. If we go, we might not reach the ca.n.a.l--and the chance of being spotted in the desert is even smaller than if we wait here at the ship." He paused. "So we move on?" He looked at the others. Astro nodded and looked at Roger, who bobbed his head in agreement.
"O.K., then," said Tom, "it"s settled. We"ll move at night when it"s cool, and try to rest during the day when it"s the hottest."
Roger looked up at the blazing white sphere in the pale-blue sky that burned down relentlessly. "I figure we have about six hours before she drops for the day," he said.
"Then let"s go back inside the ship and get some rest," he said.
Without another word, the three cadets climbed back inside the ship and made places for themselves amid the littered deck of the control room. A hot wind blew out of the New Sahara through the open port like a breath of fire. Stripped to their shorts, the three boys lay around the deck unable to sleep, each thinking quietly about the task ahead, each remembering stories of the early pioneers who first reached Mars. In the mad rush for the uranium-yielding pitchblende, they had swarmed over the deserts toward the dwarf mountains by the thousands. Greedy, thinking only of the fortunes that could be torn from the rugged little mountains, they had come unprepared for the heat of the Martian deserts and nine out of ten had never returned.
Each boy thought, too, of the dangers they had just faced. This new danger was different. This was something that couldn"t be defeated with an idea or a sudden lucky break. This danger was ever present--a fight against nature, man against the elements on an alien planet. It was a battle of endurance that would wring the last drop of moisture mercilessly from the body, until it became a dry, brittle husk.
"Getting pretty close to sundown," said Tom finally. He stood beside the open port and shielded his eyes from the glare of the sun, now slowly sinking below the Martian horizon.
"I guess we"d better get going," said Roger. "All set, Astro?"
"Ready, Roger," answered the Venusian.
The three boys dressed and arranged the food packs on their backs. Tom carried the remainder of the Martian water, two quart plastic containers, and a six-yard square of s.p.a.ce cloth, an extremely durable flyweight fabric that would serve as protection from the sun during the rest stop of the day. Roger and Astro carried the food in compact packs on their backs. Each boy wore a makeshift hat of s.p.a.ce cloth, along with s.p.a.ce goggles, a clear sheet of colored plastic that fitted snugly across the face. All three carried emergency lights salvaged from the wrecked ship.
Tom walked out away from the ship several hundred yards and studied his pocket compa.s.s. He held it steady for a moment, watching the needle swing around. He turned and walked slowly still watching the needle of the compa.s.s. He waited for it to steady again, then turned back to Roger and Astro who stood watching from the window port.
"This is the way." Tom pointed away from the ship. "Three degrees south of east, one hundred and fifty-four miles away, if everything is correct, should bring us smack on top of a major ca.n.a.l."
"So long, _Lady Venus_," said Astro, as he left the ship.
"Don"t think it hasn"t been fun," added Roger, "because it hasn"t!"
Astro fell in behind Roger, who in turn followed Tom who walked some ten feet ahead. A light breeze sprang up and blew across the surface of the powdery sand. Ten minutes later, when they stopped to adjust their shoulder packs, they looked back. The breeze had obliterated their tracks and the mountain of sand covering the s.p.a.ceship appeared to be no different from any of the other small dunes on the desert. The New Sahara desert of Mars had claimed another Earth-ship victim.
"If we can"t see the _Lady Venus_ standing still, and knowing where to look," said Astro, "how could a man in a rocket scout ever find it?"
"He wouldn"t," said Roger flatly. "And when the water ran out, we"d just be sitting there."
"We"re losing time," said Tom. "Let"s move." He lengthened his stride through the soft sand that sucked at his high s.p.a.ce boots and faced the already dimming horizon. The light breeze felt good on his face.
The three cadets had no fear of running into anything in their march through the darkness across the shifting sands. And only an occasional flash of the emergency light to check the compa.s.s was necessary to keep them moving in the right direction.
There wasn"t much talk. There wasn"t much to talk about. About nine o"clock the boys stopped and opened one of the containers of food and ate a quick meal of sandwiches. This was followed by a carefully measured ounce of water, and fifteen minutes later they resumed their march across the New Sahara.
About ten o"clock, Deimos, one of the small twin moons of Mars, swung up overhead, washing the desert with a pale cold light. By morning, when the cherry-red sun broke the line of the horizon, Tom estimated that they had walked about twenty miles.
"Think we ought to camp here?" asked Astro.
"If you can show me a better spot," said Roger with a laugh, "I"ll be happy to use it!" He swung his arm in a wide circle, indicating a wasteland of sand that spread as far as the eyes could see.
"I could go for another hour or so," said Astro, "before it gets too hot."
"And wait for the heat to reach the top of the thermometer? Uh-huh, not me," said Roger. "I"ll take as much sleep as I can get now--while it"s still a little cool."
"Roger"s right," said Tom. "We"d better take it easy now. We won"t be able to get much sleep after noon."
"What do we do from noon until evening?" asked Astro.
"Aside from just sitting under this hunk of s.p.a.ce cloth, I guess we"ll come as close to being roasted alive as a human can get."
"You want to eat now?" asked Astro.
Tom and Roger laughed. "I"m not hungry, but you go ahead," said Tom. "I know that appet.i.te of yours won"t wait."
"I"m not too hungry either," said Roger. "Go ahead, you clobber-headed juice jockey."
