Last year CBS Laboratories introduced its own playback system, called Electronic Video Recording (EVR). But the RCA version-which works through a combination of laser beams and holography-would cost the consumer only half as much. The model RCA demonstrated last week, however, was still a primitive prototype with grainy picture, color distortion and no sound...
...lunar surface brought back that dangerous moment with tense immediacy. The movies were so clear and sharp that they allowed scientists to pinpoint the landing area precisely. And with the exact coordinates to guide them, astronomers at California's Lick Observatory were finally able to bounce a laser beam off the reflecting mirror left behind by the astronauts...
...second Apollo experiment also ran into difficulty. Astronomers at the McDonald Observatory near Fort Davis, Texas, the Lick Observatory on Mount Hamilton, Calif., and the Haleakala Observatory on Maui, Hawaii, were unable to locate the lunar reflector, an arrangement of 100 prisms that they hoped would reflect laser beams from earth. The beams were to be used as a precision measuring tool that would yield, among other things, the exact distance between earth and moon, proof of whether there is really any drift between continents and accurate figures on the earth's wobble. The major reason for the trouble...
...seismometer went to work immediately. It recorded and transmitted to earth evidence of the tremors caused when Aldrin hammered tubes into the lunar surface to collect core samples. It also registered the thud when the astronauts dropped their backpacks from Eagle's hatch. But the first test of the laser reflector failed when a beam shot from California's Lick Observatory missed the reflector by about 50 miles...
...solar wind experiment, consisting of a 4-ft.-long aluminum-foil strip designed to capture particles streaming in from the sun; 2) a seismometer to. register moonquakes and meteor impacts and report them back to earth; and 3) a reflector for measuring precise earth-moon distances by bouncing laser beams from earth directly back to the source...
