The 64-inch mirror for the new Sacramento Peak Observatory telescope was made by Corning Glass Works from an "exotic" glass called fused silica. The glass was selected for the mirror because of its low-expansion properties. The mirror is located nearly 200 feet below ground

Exotic mirror
Eye board Strands of polyester yarn pass through an "eye board," or thread guide, and past the eyes of a technician at Goodyear's polyester resin plant at Point Pleasant, W.Va. The "eyes" separate the strands. These strands are among the 150 million pounds of polyester that will go into making tires this year

Space walk
NEWS HSfgODS
Youngsters take a walk in "space" at a children's exhibit held recently in Paris, France. The cagelike corridor gives the sensation of moving through space between a pair of capsules "in orbit around the earth." The show had a variety of displays, but the space one took most of the kids' attention
Reflecting graphite The 8-inch-diameter graphite "mirror" shown here is one of the largest of its kind. This highly oriented "crystal," from Union Carbide's carbon products division, is made by compression annealing pyrolytic graphite. These kinds of graphite crystals can be used for x-ray astronomy since they have a very high efficiency in diffracting x-rays and could help identify the source of stars
