"You'll find all the equipment you need at the end of this passageway," Stone said. "Activate the third door on your left. Anything else you'd like to know?"
Corriston shook his head. He walked out of the compartment backwards, keeping his gun trained on Stone until he was in the corridor. Then he swung the door shut and shot the bolt home.
He had no trouble at all in finding the equipment he knew he'd need, thanks to Stone's generosity. Stone could afford to be generous, he reflected bitterly. The Henley combine still held all of the trump cards.
He cursed the time it took him to equip himself for a near-suicidal crossing of eighty-seven miles of Martian desert. He would travel on foot, after nightfall, and in freezing cold. The compartment in which he labored was a basal compartment, and set in the massive bulkhead, against which he leaned with his bootstraps still unlaced, was an airlock opening directly on the Martian plain.
He collected the smaller articles first, setting them down in a row on a long metal bench directly opposite the airlock: three compasses, each weighing perhaps twenty ounces; a cathode ray compass; a non-magnetic compass and a sun compass. The sun compass would perhaps prove the most valuable until darkness fell. The sun, shining down with brilliance from the clear Martian sky, could throw a directional kind of shadow, enabling a man on foot to take fairly accurate bearings without the use of sighting and viewing instruments.
To the compasses on the bench he added five map coordinates and a Lambert conformal projection chart.
Food concentrates came next: four shining aluminum cubes, four inches by four inches, which would go into the knapsack on his back. Then a canteen, already filled with sterilized water from the ship's central water supply system.
Next, he took from the locker the right kind of clothing: a tubeflex inner suit with a warm lining and a heavy outer suit equipped with heat lamps.
Oxygen masks next—oxy-respirators, to be exact. One to attach to the face and one to hold in reserve as a spare. They covered only a third of the face, but that third had everything to do with a man's staying alive and vigorous in the thin air of Mars. When night fell, and the cold descended, oxy-respirators were not enough. Then you had to pull down the entire front of your helmet and stagger on with your sight impaired, for in a cold that was almost beyond endurance, helmets had a way of clouding over from time to time.
The clouding over of the vision plate was not too important. It could be constantly wiped clean. But if his brain started "clouding over" too....
