"How far?" he asked himself in a half-spoken thought, "--how far have we come?"
* * * * *
There was an instrument that ticked off the seconds in this seemingly timeless void. He pressed a small lever beside it, and, beneath a glass that magnified the readings, there passed the time-tape. Each hour and minute was there; each movement of the controls was indicated; each trifling variation in the power of the generator's blast. Chet made some careful computations and passed the paper to Harkness, who tilted the time-tape recorder that he might see the record.
"Check this, will you, Walt?" Chet was asking. "It is based on the time of our other trip, acceleration assumed as one thousand miles per hour per hour out of air--"
The scientist interrupted; he spoke in English that was carefully precise.
"It should lie directly ahead--the Dark Moon. I have calculated with exactness."
Walter Harkness had snatched up a pair of binoculars. He swung sharply from lookout to lookout while he searched the heavens.
"It's damned lucky for us that you made a slight error," Chet was telling the other.
"Error?" Kreiss challenged. "Impossible!"
"Then you and I are dead right this minute," Chet told him. "We are crossing the orbit of the Dark Moon--crossing at twenty thousand miles per hour relative to Earth, slightly in excess of that figure relative to the Dark Moon. If it had been here--!" He had been watching Harkness anxiously; he bit off his words as the binoculars were thrust into his hand.
"There she comes," Harkness told him quietly; "it's up to you!"
But Chet did not need the glasses. With his unaided eyes he could see a faint circle of violet light. It lay ahead and slightly above, and it grew visibly larger as he watched. A ring of nothingness, whose outline was the faintest shimmering halo; more of the distant stars winked out swiftly behind that ghostly circle; it was the Dark Moon!--and it was rushing upon them!
* * * * *
Chet swung an instrument upon it. He picked out a jet of violet light that could be distinguished, and he followed it with the cross-hairs while he twirled a micrometer screw; then he swiftly copied the reading that the instrument had inscribed. The invisible disk with its ghostly edges of violet was perceptibly larger as he slammed over the control-ball to up-end them in air.
Under the control-room's nitron illuminator the cheeks of Herr Doktor Kreiss were pale and bloodless as if his heart had ceased to function. Harkness had moved quietly back to the side of Diane Delacouer and was holding her two hands firmly in his.
The very air seemed charged with the quick tenseness of emotions. Schwartzmann must have sensed it even before he saw the onrushing death. Then he leaped to a lookout, and, an instant later, sprang at Chet calmly fingering the control.
"Fool!" he screamed, "you would kill us all? Turn away from it! Away from it!"
He threw himself in a frenzy upon the pilot. The detonite pistol was still in his hand. "Quick!" he shouted. "Turn us!"
Harkness moved swiftly, but the scientist, Kreiss, was nearer; it was he who smashed the gun-hand down with a quick blow and snatched at the weapon.
Schwartzmann was beside himself with rage. "You, too?" he demanded. "Giff it me--traitor!"
* * * * *
But the tall man stood uncompromisingly erect. "Never," he said, "have I seen a ship large enough to hold two commanding pilots. I take your orders in all things, Herr Schwartzmann--all but this. If we die--we die."
Schwartzmann sputtered: "We should haff turned away. Even yet we might. It will--it will--"
"Perhaps," agreed Kreiss, still in that precise, class-room voice, "perhaps it will. But this I know: with an acceleration of one thousand m.p.h. per hour as this young man with the badge of a Master Pilot says, we cannot hope, in the time remaining, to overcome our present velocity; we can never check our speed and build up a relatively opposite motion before that globe would overwhelm us. If he has figured correctly, this young man--if he has found the true resultant of our two motions of approach--and if he has swung us that we may drive out on a line perpendicular to the resultant--"
"I think I have," said Chet quietly. "If I haven't, in just a few minutes it won't matter to any of us; it won't matter at all." He met the gaze of Herr Doktor Kreiss who regarded him curiously.
"If we escape," the scientist told him, "you will understand that I am under Herr Schwartzmann's command; I will be compelled to shoot you if he so orders. But, Herr Bullard, at this moment I would be very proud to shake your hand."
And Chet, as he extended his hand, managed a grin that was meant also for the tense, white-faced Harkness and Diane. "I like to see 'em dealt that way," he said, "--right off the top of the deck."
But the smile was erased as he turned back to the lookout. He had to lean close to see all of the disk, so swiftly was the approaching globe bearing down.
* * * * *
It came now from the side; it swelled larger and larger before his eyes. Their own ship seemed unmoving; only the unending thunder of the generator told of the frantic efforts to escape. They seemed hung in space; their own terrific speed seemed gone--added to and fused with the orbital motion of the Dark Moon to bring swiftly closer that messenger of death. The circle expanded silently; became menacingly huge.
Chet was whispering softly to himself: "If I'd got hold of her an hour sooner--thirty minutes--or even ten.... We're doing over twenty thousand an hour combined speed, and we'll never really hit it.... We'll never reach the ground."
He turned this over in his mind, and he nodded gravely in confirmation of his own conclusions. It seemed somehow of tremendous importance that he get this clearly thought out--this experience that was close ahead.
"Skin friction!" he added. "It will burn us up!"
He has a sudden vision of a flaming star blazing a hot trail through the atmosphere of this globe; there would be only savage eyes to follow it--to see the line of fire curving swiftly across the heavens.... He, himself, was seeing that blazing meteor so plainly....
His eyes found the lookout; the globe was gone. They were close--close! Only for the enveloping gas that made of this a dark moon, they would be seeing the surface, the outlines of continents.
Chet strained his eyes--to see nothing! It was horrible. It had been fearful enough to watch that expanding globe.... He was abruptly aware that the outer rim of the lookout was red!
For Chet Bullard, time ceased to have meaning; what were seconds--or centuries--as he stared at that glowing rim? He could not have told. The outer shell of their ship--it was radiant--shining red-hot in the night. And above the roar of the generator came a nerve-ripping shriek. A wind like a blast from hell was battering and tearing at their ship.
"Good-by!" He has tried to call; the demoniac shrieking from without smothered his voice. One arm was across his eyes in an unconscious motion. The air of the little room was stifling. He forced his arm down; he would meet death face to face.
* * * * *
The lookout was ringed with fire; it was white with the terrible white of burning steel!--it was golden!--then cherry red! It was dying, as the fire dies from glowing metal plunged in its tempering bath--or thrown into the cold reaches of space!
In Chet's ears was the roar of a detonite motor. He tried to realize that the lookouts were rimmed with black--cold, fireless black! An incredible black! There
