...side with solar cells to make electric power out of sunlight. While OSO was getting its final push from the launching rocket's third stage, both drum and sail were spinning rapidly. After it was fully in orbit, three arms carrying spherical tanks of high-pressure nitrogen swung outward, and small nitrogen jets reduced the spin to a steady 30 r.p.m...
...more eyes (electrical light sensors ) than any spider. When it went into orbit, some of the eyes searched for the sun. and nitrogen discharged from a bottle in the drum moved the drum's axis until it was perpendicular to the sun's direction. Next, a motor on the central shaft started turning the sail so that its solar cells pointed steadily...
...will take months for scientists to interpret all the new information that OSO is sending about the sun. Every instrument on the complicated satellite is apparently doing its duty. OSO is expected to function as a solar observatory for about six months, when its supply of compressed nitrogen will be exhausted...
...wings of a butterfly. At the same time, Ranger's dish-shaped, long distance radio antenna swung out into position. A few minutes later the C.C. & S. commanded six light sensors to find the direction of the sun. Then an attitude control system of gyros and small nitrogen gas jets went into action, turning Ranger III until it locked on the still-distant sun, its broad butterfly wings absorbing maximum power from the sunlight. Some three hours later, C.C. & S. started another series of actions that turned the Ranger's rotatable dish antenna toward the receding earth. Radio...
...other compounds are broken down in combination with water. Creatures that have ammonia instead of water in their tissues, would digest food by ammonolysis, i.e., by combining it with ammonia. Instead of oxydizing food to liberate energy as earth's animals do, Jovian animals would combine it with nitrogen, and the final product would be cyanogen (CN)2, a gas that is violently poisonous to life on earth. "Jovian animals," says Astronomer Firsoff, "could breathe nitrogen and drink liquid ammonia. Whether they do remains to be seen...
