...indeed flown around the moon. It carried out its "program of research in outer space," they said, and was continuing on its flight. Then Lovell added a postscript: the Soviet news agency Tass, he told reporters, had actually called Jodrell Bank to ask what was happening to the spacecraft...
...miles of the earth; then it was lost below the horizon. When Zond failed to reappear over the opposite horizon, Lovell announced that the Russians had probably brought it down in a recovery attempt. Then, after hours of silence that led many scientists to believe that the spacecraft had not survived its plunge into the earth's atmosphere, Moscow made a dramatic announcement: Zond had splashed down "in a pre-set area of the Indian Ocean," its scientific mission ''fully carried out," and had been picked up by a Soviet ship. Western trackers confirmed the successful reentry...
...which is designed to carry two astronauts to the surface of the moon while the third remains in lunar orbit in the Apollo command module. Tests have shown that most of the LM's troubles are electrical, and technicians at Cape Kennedy are busily rewiring the spacecraft, shielding circuits and replacing switches...
When Russia's Venus 4 capsule suddenly fell silent in the thick Venusian atmosphere last October, Soviet scientists assumed that the spacecraft's final readings-a temperature of 520° F. and an atmospheric pressure 15 to 22 times greater than Earth's-described conditions on the planet's surface. Not so, say U.S. Electrical Engineers Arvydas Kliore and Dan Cain. The Venusian at mosphere, they report in the current issue of Journal of Atmospheric Sciences, is much hotter and far more crushing than the Soviets think. On the surface the temperature is actually close...
Their own figures, the two Jet Propulsion Laboratory scientists explain, are based not only on data from Venus 4 but also on transmissions from the U.S. spacecraft Mariner 5 which flew past Venus less than two days after the Russian landing. According to JPL, the Russian capsule stopped sending signals when it was 3,774 miles from the center of Venus. But recent measurements by four powerful U.S. radar installations have established that the planet's radius is only 3,759 miles. That means that at the instant Venus 4 stopped transmitting, it must have been 15 miles above...
