...provide a panoramic view of the surface activities. While Aldrin is setting up a solar wind experiment, consisting of a 1-ft. by 4-ft. aluminum-foil strip designed to capture particles streaming in from the sun, Armstrong will scoop up another 60 lbs. of lunar rocks and soil and place them in an aluminum sample...
Exploring the area within 100 ft. of the LM, Aldrin will scoop up scientifically interesting rocks, while Armstrong photographs each site and takes notes about the specimens. Armstrong will also thrust a core sampler as far as 12 in. into the soil to collect subsurface samples uncontaminated by the exhaust from the LM's descent engine. Up to 60 lbs. of documented rocks will then be placed in a seeond aluminum sample box, along with core samples and the aluminum solar particle collector, and sealed...
...Galileo's pioneering look at the lunar surface through a telescope in 1609: Unmanned spacecraft have crashed into the moon, orbited it, measured it, and photographed it from every conceivable angle, giving man his first view of the lunar far side. Ingenious soft-landing spacecraft have dug into its soil and even chemically analyzed it by remote control...
...Apollo 11 manned landing will begin returning scientific dividends as soon as Astronauts Armstrong and Aldrin start to explore the lunar surface. Both are competent amateur geologists. They have had more than 120 hours of instruction from NASA geologists, and they have practiced collecting rock and soil samples in lunarlike terrain such as the Grand Canyon, California's Medicine Lake highlands, the Arizona meteorite crater, the arctic wastelands of Iceland, and Alaska's Valley of Ten Thousand Smokes. Even their on-the-spot descriptions of the moon, to be transmitted instantaneously by radio to earth, should be of substantial value...
Beyond a doubt, however, the most important contribution of Apollo 11 to modern science will be the 100-odd lbs. of lunar rock and soil scheduled to be brought back by the astronauts. To safeguard this precious cargo, NASA has set up an elaborate system that stretches from the moon across space to Houston's $15.8 million Lunar Receiving Laboratory (LRL) and to universities and laboratories all over the world. Says LRL Curator Elbert King: "Scientifically, this will be worth more than any other material in history...
