...centered on such technical problems as the lunar module's limited fuel reserves. Because Neil Armstrong was forced at the last minute to take over the controls to avoid setting down in a boulder-strewn crater, NASA has scheduled landings on only the flattest lunar terrain until the LM's fuel capacity can be increased. That will mean no sorties into deep craters or rocky highlands for at least four more Apollo flights...
...Aldrin have so much trouble penetrating the lunar surface beyond a few inches with his core sampler? Why was he able to plant the stand for the solar wind experiment only a few feet away with such ease? Why did the blast from the LM's engine fail to carve out even a small crater...
...with the earth started with tiny microphones carried inside the astronauts' space helmets. Their voices were fed from the mikes into a small, 3-ft.-sq. box directly behind them in the lunar module. Despite its deceptively simple appearance, the 100-lb. package was the heart of the LM's communications system. Known as a signal processor, it accepted the astronauts' voices as well as 900 other signals-telemetric data on heartbeats, for example, pressure readings in the cabin, data from the computers-and imposed them on a single "carrier" frequency of 2,282.5 megahertz. An amplifier...
...also relayed the voices back into space where they were picked up by Mike Collins in the command ship, some 70 miles above their source on the lunar surface. The reason for the round trip of nearly half a million miles: Collins was in direct radio line with the LM for only 15 minutes during each two-hour orbit of the moon...
...system became still more complex after the astronauts stepped out of the LM and onto the moon. No longer hooked up with the cabin, Armstrong carried in his backpack a 61-lb. unit consisting of two transmitters and three receivers. The portable outfit sent his voice back to the LM, which then rebroadcast it to the world. Once Edwin Aldrin emerged from the cabin, he picked up Armstrong's voice directly by means of a backpack receiver of his own. Aldrin's voice, in turn, was broadcast to Armstrong by a tiny FM transmitter. It was Armstrong...
