The largest airless object inside Jupiter's orbit was Mercury, but that was so close to the Sun that the observatory in its twilight zone specialized in solar observations. Relatively small telescopes sufficed.
The second largest airless object was the Moon. Here again circumstances dictated specialization. Weather forecasts on Earth, for instance, had become an accurate, long-range science, since the appearance of Earth's atmosphere could be viewed as a whole from a distance of a quarter of a million miles.
And the third largest airless object was Ceres, and that was the best of the three. Its almost nonexistent gravity allowed huge lenses and mirrors to be poured without the danger of breakage, without even the question of sag, due to its own weight. The structure of the telescope tube itself needed no particular strength. Ceres was nearly three times as far from the Sun as was the Moon and sunlight was only one eighth as strong. Its rapid revolution kept Ceres' temperature almost constant. In short, Ceres was ideal for observation of the stars and of the outer planets.
Only the day before Bigman had seen Saturn through the thousand-inch reflecting telescope, the grinding of the huge mirror having consumed twenty years of painstaking and continuous labor.
"What do I look through?" he had asked.
They laughed at him. "You don't look through anything," they said.
They worked the controls carefully, three of them, each doing something that co-ordinated with the other two, until all were satisfied. The dim red lights dimmed further and in the pit of black emptiness about which they sat a blob of light sprang into being. A touch at the controls and it focused sharply.
Bigman whistled his astonishment. It was Saturn!
It was Saturn, three feet wide, exactly as he had seen it from space half a dozen times. Its triple rings were bright and he could see three marble-like moons. Behind it was a numerous dusting of stars. Bigman wanted to walk about it to see how it looked with the night shadow cutting it, but the picture didn't change as he moved.
"It's just an image," they told him, "an illusion. You see the same thing no matter where you stand."
Now, from the asteroid's surface, Bigman could spot Saturn with the naked eye. It was just a white dot, but brighter than the other white dots that were the stars. It was twice as bright as it appeared from Earth, since it was two hundred million miles closer here. Earth itself was on the other side of Ceres near the pea-size Sun. Earth wasn't a very impressive sight, since the Sun invariably dwarfed it.
Bigman's helmet suddenly rang with sound as the call flooded his left-open radio receiver.
"Hey, Shortie, get moving. There's a ship coming in."
Bigman jumped at the noise and moved straight upward, limbs flailing. He yelled, "Who're you calling Shortie?"
But the other was laughing. "Hey, how much do you charge for flying lessons, little boy?"
"I'll little boy you," screamed Bigman furiously. He had reached the peak of his parabola and was slowly and hesitatingly beginning to settle downward once more. "What's your name, wise guy? Say your name, and I'll crack your gizzard as soon as I get back and peel the suit.
"Think you can reach my gizzard?" came the mocking rejoinder, and Bigman would have exploded into tiny pieces if he had not caught sight of a ship slanting down from the horizon.
He loped in giant, clumsy strides about the leveled square mile of ground that was the asteroid's space-port, trying to judge the exact spot on which the ship would land.
It dropped down its steaming jets to a feather-touch planetary contact and when the air-locks opened and Lucky's tall, suited figure emerged, Bigman, yelling his joy, made one long leap of it, and they were together.
Conway and Henree were less effusive in their welcome, but no less joyful. Each wrung Lucky's hand as though to confirm, by sheer muscular pressure, the reality of the flesh and blood they beheld.
Lucky laughed. "Whoa, will you? Give me a chance to breathe. What's the matter? Didn't you think I was coming back?"
"Look here," said Conway, "you'd better consult us before you take off on just any old fool notion."
"Well, now, not if it's too much of a fool notion, please, or you won't let me."
"Never mind that. I can ground you for what you've done. I can have you put under detention right now. I can suspend you. I can throw you off the Council," said Conway.
"Which of them are you going to do?"
"None of them, you darned overgrown young fool. But I may beat your brains out one of these days."
Lucky turned to Augustus Henree. "You won't let him, will you?"
"Frankly, I'll help him."
"Then I give up in advance. Look, there's a gentleman here I'd like to have you meet."
Until now Hansen had remained in the background, obviously amused by the interchange of nonsense. The two older Councilmen had been too full of Lucky Starr even to be aware of his existence.
"Dr. Conway," said Lucky, "Dr. Henree, this is Mr. Joseph P. Hansen, the man whose ship I used to come back. He has been of considerable assistance to me."
The old hermit shook hands with the two scientists.
"I don't suppose you can possibly know Drs. Conway and Henree," said Lucky. The hermit shook his head.
"Well," he went on, "they're important officials in the Council of Science. After you've eaten and had a chance to rest, they'll talk to you and help you, I'm sure."
An hour later the two Councilmen faced Lucky with somber expressions. Dr. Henree tamped tobacco into his pipe with a little finger, and smoked quietly as he listened to Lucky's accounts of his adventures with the pirates.
"Have you told this to Bigman?" he asked.
"I've just spent some time talking to him," said Lucky.
"And he didn't assault you for not taking him?"
"He wasn't pleased," Lucky admitted.
But Conway's mind was more seriously oriented. "A Sirian-designed ship, eh?" he mused.
"Undoubtedly so," said Lucky. "At least we have that piece of information."
"The information wasn't worth the risk," said Conway, dryly. "I'm much more disturbed over another piece of information we have now. It's obvious that the Sirian organization penetrates into the Council of Science itself."
Henree nodded gravely. "Yes, I saw that, too. Very bad."
Lucky said, "How do you make that out?"
"Galaxy, boy, it's obvious," growled Conway. "I'll admit that we had a large construction crew working on the ship and that even with the best intentions careless slips of information can take place. It remains truth, though, that the fact of the booby-trapping and particularly the exact manner of the fusing were known only to Council members and not too many of those. Somewhere in that small group is a spy, yet I could have sworn that all were faithful." He shook his head. "I still can't believe otherwise."
"You don't have to," said Lucky.
"Oh? And why not?"
"Because the Sirian contact was quite temporary. The Sirian Embassy got their information from me"

Bigman Takes Over
"Indirectly, of course, through one of their known spies," he amplified, as the two older men stared at him in shocked astonishment.
