...rocks appear to be quite different from what we saw on Apollo 11 and 12." Since most lunar rocks are gray, the geologists were particularly eager to analyze a fragment chipped from a puzzling white boulder that the astronauts spotted on the slope of Fra Mauro's Cone Crater. The odd white sample, which contains a few dark flecks and streaks, may be as old as the moon and solar system: 4.6 billion years. As insurance against any loss of Apollo 14's precious cargo, NASA divided the rocks into two batches for the trip to Houston, shipping...
...fifth and sixth human visitors to the moon crisscrossed their Fra Mauro landing site, set up a $25 million package of scientific instruments, collected 108 lbs. of rocks and soil, and ventured more than half a mile from their ship up the 400-ft.-high walls of a crater...
Ancient Highlands. Apollo 14, scheduled to lift off on Sunday, Jan. 31, at 3:23 p.m. E.S.T., will head for the same hilly region near the crater Fra Mauro that was the target of its ill-fated predecessor. If all goes well, the Apollo 14 astronauts will become the first human visitors to the lunar highlands. There they may be able to recover rocks dating back to the birth of the moon, more than 4.5 billion years ago. The lunar landing maneuvers will differ in important details from the two previous successful manned lunar expeditions. For one thing, the command...
...Shepard and Mitchell are scheduled to emerge for their second EVA and load up their new collapsible two-wheeled lunar handcart with cameras, hand tools, shovel and sampling cores. Then they will begin their major geological traverse: a rock-collecting hike up the side of 400-ft.-high Cone Crater, nearly a mile away. Although the two lunar mountaineers will not descend into the crater itself, they will conduct a kind of rock festival on its rim: they will chip stone from large boulders and roll some smaller boulders down the crater's side (the tracks will give earthbound...
...fields and the variations in the velocity of seismic waves under different parts of the West. He also points to much more conspicuous signs of its presence: the hot springs in California and Yellowstone National Park, the remnants of old volcanoes-Arizona's Kitt Peak, for example, and Crater Lake in Oregon-the upward tilt of the American plains as they stretch westward toward the Rockies and the shape of the mountains themselves. Unlike the Andes or even the closer Canadian Rockies -both of which were squeezed up by massive lateral pressures-the American Rockies seem to have been...
