Immediately he turned up his oxygen intake, at the same time glancing at the clock dial in his helmet. He smiled. Nineteen days and seven hours. He had calculated it almost precisely.
He wasn't more than an hour off, which was really pretty good, all things considered.
He consulted his instruments again. The supply ship was ten minutes away. The smile stayed on his face as he prepared for further action.
The first two minutes were conscientiously spent in inhaling oxygen. Even under the best cataleptic conditions, the human body tended to slow down too much. He had to get himself prepared for violent movement.
Eight minutes left.
He climbed out of the little grotto where he had concealed himself and moved toward the spot where he knew the airlock to the caverns underneath the planetoid's surface was hidden.
Then again he concealed himself and waited, while he continued to breathe deeply of the highly oxygenated air in his suit. Five minutes before the ship landed, he swallowed eight ounces of the nutrient solution from the tank in the back of his helmet. The solution of amino acids, vitamins, and honey sugar also contained a small amount of stimulant of the dexedrine type and one percent ethanol.
He waited for another minute for the solution to take effect, then he unholstered his gun.
The supply ship wasn't a big one. He had known it wouldn't be. It was only a little larger than the one he had used to come out here. It dropped down to the surface of the small planetoid only ten meters from the hidden trapdoor that led to the airlock beneath the surface.
Suddenly he could hear voices in the earphones of his helmet.
