Soap-Bubble Film. The density of an atmosphere detected in this way depends partly on what gases it contains, and the radio waves give no such information. Elsmore points out that the moon's gravitation is too feeble to hold comparatively light gases like the oxygen and nitrogen in the earth's atmosphere. Any gas molecules that hang around the moon for long must be much heavier. But the moon may have in addition a temporary atmosphere made of helium and argon given off by radioactivity in the moon's rocks and of other light gases escaping...
...suit over his figure-hugging space suit, dumped some ballast (including two spent batteries), and climbed back to safety. An hour before sunrise, he radioed a plea to the ground: "I've got to get some sleep!" Permission was granted; the gondola, conditioned by pressurized oxygen, helium and nitrogen, was awesomely hushed. "It's like no earthly quiet," he reported. "On earth there are always traffic sounds and dogs barking or the wind just whistling. But in space there's nothing but quiet." He leaned his head forward against his chest-pack parachute and promptly dropped...
...Aviation Medicine. They collected soil samples from the high slopes of Mt. McKinley, the Painted Desert and the Grand Canyon, where the climate in some respects is almost as tough as on Mars. They put the samples in jars and replaced the oxygen-rich earthly air with dry nitrogen. They lowered the moisture content to below 1% and reduced the pressure to 1.2 Ibs. per square inch to simulate the thin Martian atmosphere...
...closed cylinder 3 ft. in diameter and 7 ft. tall. The lid was clamped shut, and the air inside was replaced by a helium-oxygen mixture. This was to denitrogenize Kittinger so that a sudden drop in pressure would not give him the bends by releasing bubbles of nitrogen in his blood. From this point on, his voice sounded somewhat squeaky; helium raises the pitch of the voice by about one octave...
...Cookery. Raytheon regards its new process as experimental, and it does not know yet how long freeze-dried foods will keep at room temperature. They can be stored in plastic envelopes filled with nitrogen to prevent oxidation, but in the case of meat that contains fat there may be a tendency to deteriorate with time. Elaborate tests are now in progress to find the best ways to package and store them...
