...service propulsion system) engine will be fired for 246 sec. to slow the spacecraft and allow it to be pulled by the moon into a 70-by 196-mile elliptical lunar orbit. Two revolutions later, a brief 10-sec. burn will change the path to a 70-mi.-high circular orbit. Traveling at 3,640 m.p.h., Apollo will circle the moon once every two hours. For 45 nerve-racking minutes during every revolution-when it is behind the moon and blocked from radio communication with the earth-it will be out of touch with ground controllers...

Not far off was the Pactolus Torrent, which once was noted for its gold-rich sands. Moreover, slag similar to that produced in metal smelting rimmed the edges of the depressions. Ramage and his colleagues soon realized that they had stumbled on an ore refinery...
Careful digging revealed that the circular depressions were cupels, or metal-refining bowls. Unearthed with them were four furnaces, remnants of bellows, tiny bits of gold and gold alloys, and pottery fragments from the time (570-547 B.C.) when Croesus ruled the Lydian Empire in what is now western Turkey...
