...readying Glenn's Atlas-D booster and space capsule for safe flight. After that, in nerve-racking order, came delays caused by a faulty fuel valve in the booster, a malfunction in the cooling system of Glenn's spacesuit, a breakdown in the capsule's oxygen supply unit...
...While Eltanin's biologists ply their nets and trawls and her radiomen tune for whistlers, meteorologists studying the turbulent Antarctic atmosphere will launch weather balloons from a sheltering hangar on the ship's stern. Oceanographers will study the tossing sea water by measuring its temperature, salinity, and oxygen content at all depths ranging up from the bottom. They will chart ocean currents and plunge long tubular probes into the ocean floor. The cores of silt they bring up will give glimpses of Antarctic geologic history over millions of years...
This time the trouble was traced to a layer of insulation in the Atlas-D's giant fuel tank (65 ft. high; 10 ft. in diameter). The insulation had somehow absorbed some kerosene-like fuel, which is mixed with liquid oxygen when the missile is fired. Engineers set about correcting the fault, and space scientists got ready to start the complex preflight tests all over again. Scheduled date for the next...
Long Wait. For hours before Glenn's scheduled shot, everything seemed A-OK. Technicians had fixed a malfunction in the capsule's oxygen-supply system that had caused an earlier postponement. Around the world, 18 tracking stations were ready to follow Glenn's three orbits. In the Atlantic, three flotillas of ships were patrolling back and forth to pick him up at designated landing spots. The Atlas-D rocket had been checked out by an engineer who slowly swung his way up through the maze of pipes and valves that form the missile's innards...
...reckoned with. A 50-megaton blast could ignite frame houses up to 60 miles from Ground Zero, burning or asphyxiating many people in basement fallout shelters-or tumbling their houses down on them. Scientists also think a nuclear blast might produce a fierce fire storm, which would suck up oxygen over large areas and kill all in its path-but no one can be certain...
