...solar wind and the Venusian ionosphere. The Russians at first reported that carbon dioxide comprised 98% of the Venusian atmosphere, but later revised the figure down to between 90% and 95%, closer to Mariner's reported 72% to 87%. And while Mariner could find no evidence of oxygen in the atmosphere, the Venus 4 capsule reported a trace (.4 of 1%) of oxygen and some water vapor...
...dressing room in a wheelchair to ease the pain of a crushed disk in her back, and dismisses visitors with the sigh, "I must do my breathing now." Since pneumonia damaged her lungs in 1961, she has had to inflate them several times a day with a pressurized oxygen tank that accompanies her everywhere (she calls it "Charlie...
...pressures up to 15 times as great as the earth's and determined that the atmosphere consists almost entirely of carbon dioxide, which, scientists believe, is spewed out by volcanic activity. No trace of nitrogen (which constitutes 78% of the earth's atmosphere) and only 1.5% of oxygen and water vapor were detected. In readings made before Venus 4 entered the atmosphere, the Russians could find no evidence of a Venusian magnetic field and radiation belt...
...Liquid oxygen (LOX) is used as an oxidizer in rocket engines and in steel production. Liquid hydrogen has been proposed as the fuel for the supersonic transport and as the propellant in a nuclear rocket. In bubble chambers, it allows scientists to trace the path of sub-atomic particles. Gas companies are liquefying natural gas for more convenient and economical storage, and liquid nitrogen is now used to freeze the earth around excavations so that mud will not slide into the work area...
...membrane, they calculate, the organisms could range from the size of a pingpong ball to more complex and thicker-skinned gas spheres many times larger. Despite their internal hydrogen, Sagan jokes scientifically, there would be little danger of miniature Hindenburg disasters; there is little or no free oxygen in the Venusian atmosphere to support an explosion of hydrogen...
