"Then blast off for Mars!" ordered Tom, and the air car shot away from the station and moved up into the stream of expressway traffic fifty feet above the ground.
As the little car sped along the broad avenue, Tom remembered how often, as a boy, he'd envied the Space Cadets who'd come to his home town of New Chicago on leave. Now here _he_ was--in uniform, with a three-day pass, and all of Atom City to enjoy it in.
A few minutes later the air car stopped in front of the Mars Hotel. The cadets saw the entrance loom before them--a huge opening, with ornate glass and crystal in many different colors.
They walked across the high-ceilinged lobby toward the desk. All around them, the columns that supported the ceiling were made of the clearest crystal. Their feet sank into soft, lustrous deep-pile rugs made of Venusian jungle grass.
The boys advanced toward the huge circular reception desk where a pretty girl with red hair waited to greet them.
"May I help you?" she asked. She flashed a dazzling smile.
"You're a lucky girl," said Roger. "It just so happens you _can_ help me. We'll have dinner together--just the two of us--and then we'll go to the stereos. After which we'll--"
The girl shook her head sadly. "I can see your friend's got a bad case of rocket shock," she said to Tom.
"That's right," Tom admitted. "But if you'll give us a triple room, we'll make sure he doesn't disturb anybody."
"Ah," said Roger, "go blow your jets!"
"I have a nice selection of rooms here on photo-slides if you'd care to look at them," the girl suggested.
"How many rooms in this hotel, Beautiful?" asked Roger.
"Nearly two thousand," answered the girl.
"And you have photo-slides of all two thousand?"
"Why, yes," answered the girl. "Why do you ask?"
"You and Astro go take a walk, Corbett," said Roger with a grin. "I'll select our quarters!"
"You mean," asked the girl, a little flustered, "you want to look at all the slides?"
"Sure thing, Lovely!" said Roger with a lazy smile.
"But--but that would take three hours!"
"Exactly my idea!" said Roger.
"Just give us a nice room, Miss," said Tom, cutting in. "And please excuse Manning. He's so smart, he gets a little dizzy now and then.
Have to take him over to a corner and revive him." He glanced at Astro, who picked Roger up in his arms and walked away with him as though he were a baby.
"Come on, you space Romeo!" said Astro.
"Hey--ouch--hey--lemme go, ya big ape. You're killing your best friend!"
Roger twisted around in Astro's viselike grasp, to no avail.
"Space fever," explained Tom. "He'll be O.K. soon."
"I think I understand," said the girl with a nervous smile.
She handed Tom a small flashlight. "Here's your photoelectric light key for room 2305 F. That's on the two hundred thirtieth floor."
Tom took the light key and turned toward the slidestairs where Astro was holding Roger firmly, despite his frantic squirming.
"Hey, Tom," cried Roger, "tell this Venusian ape to let me go!"
"Promise to behave yourself?" asked Tom.
"We came here to have fun, didn't we?" demanded Roger.
"That doesn't mean getting thrown out of the hotel because you've got to make passes at every beautiful girl."
"What's the matter with beautiful girls?" growled Roger. "They're official equipment, like a radar scanner. You can't get along without them!"
Tom and Astro looked at each other and burst out laughing.
"Come on, you jerk," said Astro, "let's get washed up. I wanta take a walk and get something to eat. I'm hungry again!"
An hour later, showered and dressed in fresh uniforms, the _Polaris_ crew began a tour of the city. They went to the zoo and saw dinosaurs, a tyrannosaurus, and many other monsters extinct on Earth millions of years ago, but still breeding in the jungles of Tara. They visited the council chamber of the Solar Alliance where delegates from the major planets and from the larger satellites, such as Titan of Saturn, Ganymede of Jupiter, and Luna of Earth made the laws for the tri-planetary league. The boys walked through the long halls of the Alliance building, looking at the great documents which had unified the solar system.
They reverently inspected original documents of the Universal Bill of Rights and the Solar Constitution, which guaranteed basic freedoms of speech, press, religion, peaceful assembly and representative government. And even brash, irrepressible Roger Manning was awestruck as they tiptoed into the great Chamber of the Galactic Court, where the supreme judicial body of the entire universe sat in solemn dignity.
Later, the boys visited the Plaza de Olympia--a huge fountain, filled with water taken from the Martian Canals, the lakes of Venus and the oceans of Earth, and ringed by a hundred large statues, each one symbolizing a step in mankind's march through space.
But then, for the Space Cadets, came the greatest thrill of all--a trip through the mighty Hall of Science, at once a museum of past progress and a laboratory for the development of future wonders.
Thousands of experiments were being conducted within this crystal palace, and as Space Cadets, the boys were allowed to witness a few of them. They watched a project which sought to harness the solar rays more effectively; another which aimed to create a new type of fertilizer for Mars, so people of that planet would be able to grow their own food in their arid deserts instead of importing it all from other worlds. Other scientists were trying to adapt Venusian jungle plants to grow on other planets with a low oxygen supply; while still others, in the medical field, sought for a universal antibody to combat all diseases.
Evening finally came and with it time for fun and entertainment. Tired and leg weary, the cadets stepped on a slidewalk and allowed themselves to be carried to a huge restaurant in the heart of Atom City.
"Food," exulted Astro as the crystal doors swung open before them.
"Smell it! Real, honest-to-gosh food!" He rushed for a table.
"Hold it, Astro," shouted Tom. "Take it easy."
"Yeah," added Roger. "It's been five hours since your last meal--not five weeks!"
"Meal!" snorted the Venusian cadet. "Call four spaceburgers a meal? And anyway, it's been six hours, not five."
Laughing, Tom and Roger followed their friend inside. Luckily, they found a table not far from the door, where Astro grabbed the microphone and ordered his usual tremendous dinner.
The three boys ate hungrily as course after course appeared on the middle of the table, via the direct shaft from the kitchen. So absorbed was Manning that he did not notice the approach of a tall dark young man of about his own age, dressed in the red-brown uniform of the Passenger Space Service. But the young man, who wore a captain's high-billed hat, suddenly caught sight of Roger.
"Manning," he called, "what brings you here?"
"Al James!" cried Roger and quickly got up to shake hands. "Of all the guys in the universe to show up! Sit down and have a bite with us."
