...photographic outpouring also pleased scientists at the Lunar Receiving Laboratory, who found the pictures highly useful in initial identification and examination of the freshly arrived lunar rocks last week. Geochemist Paul Cast, the Manned Spacecraft Center's chief lunar scientist, noted, for example, that the closeups of the moon's surface were so clear that the orange soil showed up as a distinct band in the surrounding material. To Cast, those sharp color boundaries were another indication that the orange soil is young by lunar standards and a product of relatively recent volcanism on the moon...
...Wasserburg jumped up from his fourth-row seat and practically pressed his nose against the TV screen to see the coloring for himself. NASA'S Egyptian-born geologist Farouk El Baz, who had helped train the astronauts, beamed proudly. Even the space agency's cautious Australian-born Geochemist Robin Brett exulted: "We have witnessed one of the important finds in Apollo geology...
...finally have the services of a professional geologist on the moon. The Taurus-Littrow landing site contains what may be small, volcanically created cinder cones; they seem to be miniature versions of earthly features like Honolulu's Diamond Head. The cones may well be remnants of what NASA Geochemist Robin Brett calls "some of the last belches of lunar activity before the moon turned off." Finally, Apollo 17 planners have scheduled a program of experiments and observation far more sophisticated than any of the earlier scientific efforts on the moon...
...what the astronauts and their cameras saw were fragments called breccias, which are forged together from still more ancient rocks. At the very least, that unexpected finding means that the Cayley Plains were formed, not simply by volcanic flows, but by far more complex geological processes. Said NASA Geochemist Robin Brett: "We went to the right place for the wrong reasons...
...Shortly thereafter the newborn moon was rapidly heated, possibly by its radioactive elements, and underwent surface melting about 4.5 billion years ago. In contrast with delegates to previous "rock conferences," the experts assembled this year were unusually reticent about advancing new theories on the moon's evolution. Said Geochemist Paul Cast, chief lunar scientist at the Manned Spacecraft Center: "We have so much data to examine that the boys just aren't doing much speculating." Added NASA Geochemist Robin Brett: "The Apollo 15 material alone will keep us busy for about five years...
