...relevance" means something deeper than "newspaperliness," then it must mean potential for understanding and control over life. In this sense, a relevant arithmetic problem in an eighth grade text might be: The curves in Fig. 6.48 give the values of apparent crater diameter and depth in dry soil as a function of explosion veiled. Given a 20 KT surface burst over sandstone, find the crater dimensions. (Effects of Nuclear Weapons, 4th ed.) Such a reorientation in education might alter the balance of interest on the part of children away from TV or comics toward school...
Most striking of all are the closeups of Surveyor 3, which had not been seen by man since it was sent to the moon some 2½ years ago. In one shot, Astronaut Conrad is shown examining Surveyor as it stands in its crater. In the background, protruding above the crater's edge, only 600 ft. away, Intrepid and the nearby umbrella antenna gleam in the sunlight. To the dismay of scientists-who wanted to study the discoloration of Surveyor's white paint-all of the Surveyor pictures are in black and white; while photographing the little craft...
...week's end, as Apollo 12's astronauts bedded down in the LRL for the remainder of their 21-day quarantine, NASA was making plans for its next lunar expedition. Buoyed by the bull's-eye at Surveyor Crater, the space agency tentatively scheduled the launch of Apollo 13 for March 12 and picked the most difficult site to date for man's next lunar landing: the ancient highlands near the mountain-ringed crater Fra Mauro...
When the Apollo 12 astronauts landed and walked to the edge of the crater, Whitaker pre dicted last week, they would see the spacecraft...
...from the spectacular cluster of airborne spheres originally proposed but ruled out by a congressional budget slash. But the design is still a spectacular achievement. From the air it may look like a king-size mattress pad, but from ground level the thing it most resembles is a moon crater roofed over with a shallow, translucent dome. The pavilion covers an oval area approximately the size of two football fields. Its solid, earth-filled walls slope as gently inward and upward as the lower slopes of Fujiyama. Halfway up, the solid earth gives way to an airy, translucent blister. Made...
