...astronauts and the Apollo craft are indeed harboring alien organisms, the bugs could escape into the air when the hatch is opened, or be washed into the ocean while the astronauts are donning their biological suits. If the organisms are fond of oxygen or nitrogen-or thrive in salt water -they could begin to spread and multiply. Most scientists agree that the chances of life on the moon are remote, and some believe that any moon organisms would have reached the earth long ago on particles ejected from the moon during meteor impacts. If they are wrong, however, and Apollo...
...granaries, temples, citadels and cemeteries. But a basic question remained unanswered. Where were the waterworks capable of supporting such a metropolis in the arid Holy Land? The puzzle has now been solved by Archaeologist Yigael Yadin, a former chief of staff of the Israeli army. He has discovered a water system as impressive as the city itself...
Yadin knew that ancient engineers dug deep tunnels under city walls to nearby springs. Once the source had been tapped and its waters brought underground into the city, the municipal water supply could not be cut off by besieging armies. When he surveyed the Hazor tell last fall, Yadin saw at its foot a network of seeping springs. Above them, atop the tell, was a large, shallow depression. Sure that the springs and the depression were related, Yadin put 160 diggers to work sinking test holes...
...older cities. As Yadin was removing rubble near the bottom of the shaft, "a rush of hot air hit me in the face." He had uncovered a 12-ft.-high tunnel that had been sealed since Biblical times. At its other end, 100 ft. away, Yadin saw water sparkling in the torchlights. Instead of depending on springs, Ahab's engineers had dug deep to tap the natural ground water reservoir. The stonework shaft's 10-ft-wide stairways sloped gently down to the tunnel mouth and were roomy enough, Yadin believes, to accommodate two columns of donkeys...
Yadin plans to clear out the shaft, install guard railings on the stairway and restore the entire waterworks system. 'We will not need the water for siege periods," says the soldier-archaeologist confidently, "but it will come in handy for tourists and visitors...
