...camera down a nylon conveyor (similar to a clothesline on pulleys), and then back down the ladder himself. The astronauts will move next to the opened storage area, called MESA, for Modularized Equipment Storage Assembly. Armstrong will detach the TV camera and place it on a stand about 30 ft. from the LM to 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...
From an equipment bay on the other side of the LM, the busy spacemen will remove EASEP (for Early Apollo Scientific Experiments Payload). They will set up one part of the package?a laser-beam reflector?some 70 ft. from the LM. The other experiment, a seismometer for measuring moonquakes and meteor impacts, will be placed 10 ft. farther away. Both will be left on the moon for the benefit of earthbound scientists (see following section...
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...
Before they depart, the astronauts will leave behind three items of symbolic import: a 3-ft. by 5-ft. U.S. flag stiffened with thin wire so that it will appear to be flying on the windless surface of the moon; a silicon disk bearing good-will messages for posterity from world leaders, including President Tito, Pope Paul and Queen Elizabeth; and a metal plaque bearing the names not only of the three astronauts, but also of President Richard M. Nixon, a fact that has stirred some criticism...
...more accurate surface than terrestrial mirrors by shaping it with ion beams (which are effective only in a vacuum) instead of abrasives. Several astronomers have pointed out that round lunar craters lined with chicken wire would make ideal reflectors for radio telescopes similar to the 1,000-ft. Cornell University radio dish, set in a rounded valley near Arecibo, Puerto Rico...
