On leaving the metal shed which had housed his one-man vehicle, Ted Dustin hovered for a moment to get his bearings—then shot away from the earth at such speed that his exterior thermometer registered a terrific heat from the shell of his craft before five seconds had elapsed. Forced to slacken his speed because of the danger of crippling his machine, he proceeded at a more leisurely pace until his instruments told him he was entirely out of the earth’s atmosphere. Once assured of this, he set his meteoroid detector—an extremely sensitive magnetic instrument which registered the approach of all meteoric masses, automatically repelling the smaller ones by blasts from the exhaust of the atomotor, and driving the craft away from those of greater mass. He next set his automatic course corrector, which was designed to throw the machine back on its course after each forced deviation. Then he set the motor for full speed ahead. To his surprise and satisfaction he found, on glancing at the magnetic speedometer, that the little untested motor was driving the craft almost twice as fast as he had anticipated. He would thus, barring accidents, be able to reach the moon in a day and a half instead of the three days he had previously allowed himself for the undertaking. This necessitated the setting of a new course, as he would otherwise have arrived at the moon’s path just a day and a half ahead of that satellite. Having made his calculations and adjusted his instruments accordingly, he opened his visor, swallowed a concentrated food pellet, drank a cup of hot coffee from the thermos tank, and lighted his black briar. Finding the cabin uncomfortably cold with his visor open, he drew up an extra set of glass panels all around and turned on his atomic heater. Then he studied the translations of the professor, hoping that he might thus learn enough of the Lunite writing to form a basis for intelligent communication. When the first hour had elapsed he looked back at the earth, which appeared as an enormous, semi-luminous globe set in a black sky, its seas and continents faintly defined by the light of the full moon. The disc of the sun remained hidden behind the earth, but other heavenly bodies were far brighter in appearance, shining from this black sky, than he had ever seen them appear from on earth. As the hours passed and the apparent size of the earth grew less while that of the moon grew correspondingly greater, he was surprised at not having encountered a single meteor. Presently, after about twelve hours of travel, one caused the craft to swerve, and he noticed with satisfaction that the automatic course corrector functioned perfectly.
