At the four thousand-mile mark, the earth had retreated to a green ball that floated atop a stream of unbearably bright stars. From this height above the planet's surface, not even the most powerful telescope would have revealed the scenes of rampant disease and flaming destruction being enacted on the broad continents below.
The entire vessel shook in a kind of bone-cracking vibration, lurching and lumbering as if some malign influence had tampered with every rivet and seam-weld in her plates.
More apprehensive than ever, Dollard finally yielded to his fears and surrendered his controls to the robot pilot. His huge body rendered almost weightless, he pulled himself along the rail guards of a catwalk that led to the unmanned engine room. Here he inspected every instrument dial to be found although the readings on many of them were repeated on duplicates in the bow.
It was then, while the ship was still a thousand miles from the no-pull point where free-wheeling alone had been known to carry vessels out of Terra's gravitational range and into Venus' orbit, that disaster struck. The fuel being fed to exactly half of the rocket tubes choked out, and the blast from the remaining tubes increased proportionately.
Under this new impetus, the vessel's frame shuddered. Its nose suddenly described a wild arc among the gyrating stars. The diversion of inertia was a more severe blow than a meteor collision would have been. Thrust was an exceedingly difficult thing to plot in free space. Dollard, screaming in panic, was flung against a network of metal braces; despite his weightlessness, his mass was great as ever and a sharp steel corner gouged a deep bleeding slash in his puffy cheek. Sickened, he crawled forward through the spinning ship until he was once more able to pull himself up into the pilot's chair.
There, he discovered the second battery of tubes had ceased firing about a minute after the first. But the changed vectors had already done their damage to both ship and heading.
quick run-through on the course-calculator soon revealed to Dollard how desperate his position was. Mathematically, Venus was now a goal impossible to attain. To re-correct his altered heading would require more fuel than his tanks had carried at take-off, thanks to sabotage. He also had the vast gravitational field of the sun to battle—a powerful sucking force, which if left to work its will could grow insidiously from a gentle tug of a few millimeters per second to a powerful acceleration eighty times terrestrial escape velocity—and this, without ever once relinquishing its hold on the slightest particle of mass in its grip.
Cursing and fuming, Dollard plotted and re-plotted, some of the rustiness of his brain wearing off as he matched his wits against the prospect of death by holocaust. But, all the resources of higher mathematics failed to point toward a solution. An artery commenced to throb painfully above his ear.
