...time Skylab reached orbit, NASA controllers were sure that it was in trouble. As the 85-ton spacecraft began circling the earth, it jettisoned its protective shroud, moved its telescope mount into place and unfolded the four windmill-like solar wings that sit above it. But indications were that the remaining solar wing on the Orbital Workshop could not swing out more than a few degrees from the ship and was thus not able to unfold its light-gathering panels. That was bad news indeed. It meant that Skylab was deprived of more than half its electrical power. Even...
...higher. The fierce heat endangered the foodstores, especially the new gravy-rich dishes of which NASA is so proud. It may well have fogged sensitive film and ruined medical supplies. There was also danger that the extreme heat would begin to decompose the Styrofoam insulation in the spacecraft's walls, producing potentially lethal gases inside the workshop. Finally, as the temperature of the unprotected aluminum "bald spot" on Skylab's exterior rose to 325°, engineers feared that the skin itself might buckle or even rupture...
...Saturn 5 rockets their final boost to the moon. Properly handled, hydrogen might be burned to heat homes, generate electricity or power cars; the only major waste product is water. A more direct use of hydrogen could be in efficient fuel cells -battery-like devices, also used in spacecraft, that produce an electric current from a reaction of hydrogen and oxygen...
...largest, most complex spacecraft ever built. Stretching 118 ft. from end to end, it weighs 100 tons, and has the interior space and most of the comforts of a three-bedroom house: private sleeping compartments for its three passengers, a dining table, a shower, a lavatory larger than any commercial airliner's and an 18-in. porthole to provide a view of the earth. To sustain its crews, it carries 720 gal. of drinking water, more than 2,000 Ibs. of food and enough scientific and medical gear for months of experimentation. Both inside and out, it would make...
Whatever the reason for their attraction to the show, Star Trek fans, or "Trekies" as they call themselves, are a devoted lot. In between watching Star Trek reruns they keep themselves busy collecting Star Trek magazines, books, bumper stickers, wall posters, pendants, spacecraft models and assorted memorabilia from the show. Most of the items are sold by Roddenberry's firm, Star Trek Enterprises, but the 24 or so Star Trek magazines, or "fanzines," are put out by the fans themselves...
