...editors already knows, TIME'S weekly contract with its readers does not end once the magazine goes to press. Every one of the 1,000 or more letters that arrive in the mail each week receives a reply from TIME'S Letters Department, which is headed by Maria Luisa Cisneros and staffed by 13 assistants. The letters department also performs a less well-known task: answering the 150 or so letters a week from people requesting information-some additional bit of elaboration or an answer to a question. That is the demanding job for Marian Powers, Carla Lyddan...
...most satisfying parts of our work," says Maria Luisa, "is simply putting our readers in touch with other people-so they can exchange ideas and even help solve a problem." She remembers a Hungarian agronomist who had read in TIME about a California farmer whose artichoke crop was being ruined by mice. We gave him the farmer's address, and perhaps, after all, he did have a better mousetrap...
Those added years had startling geological implications. They meant that the moon's maria, or seas, were not created by relatively recent-and possibly continuing-volcanic activity. Instead, the maria had probably survived largely intact since early in the moon's life. Because the relatively uncratered maria are probably the last major features to have been formed on the lunar surface, the moon's appearance has remained essentially unchanged for billions of years. "It's something, isn't it?" Urey reflected last week. "Rocks sticking up above the surface . . . perhaps they haven't changed...
...Lunar Receiving Lab's examination will continue until the rocks are released from quarantine this month, it has not yet answered any of the basic questions about the moon's origin. But if the moon is actually proved never to have had a molten interior (the maria melting could have been caused by meteor impacts), scientists would be hard put to sustain one of the theories of the moon's creation: that it was torn, cataclysmically, from a hot earth. On the other hand, a cold moon does not upset either of the two other major moon...
...more than a billion years younger than the planet itself, and the moon rocks from the Sea of Tranquillity are about the same age. Nonetheless, Urey and other cold-moon proponents think that when men reach the lunar highlands, which are generally considered to be older than the maria, they will find material as old as 4.5 billion years-or almost as old as the solar system itself...
