...said no prayers. "I feel the same way as Scott," she explained, referring to Carpenter's conviction that it is presumptuous to pray for oneself. After blastoff, she turned to watch the rest on television. She later admitted that she felt concerned only when first reports showed that radar contact had been lost with the space capsule after reentry. Beyond that, she had no worries: "I've been thoroughly checked out, and I've watched the egress [escape from the capsule] many times...
Measuring the distance to Mars or other such far-out planets is far trickier; they are well beyond the useful range of available radar. Astronomers calculate the interplanetary distance by observing the time it takes for Mars to complete one orbit around the sun and comparing that time with the earth's own time on its orbit. Since the distances of the planets from the sun are in proportion to their periods of revolution, the radius of the Martian orbit can thus be measured in terms of the basic "astronomical unit": the average distance of the earth from...
...error. Dr. Lowther hopes to clear up this unhappy situation by lofting a small satellite into an orbit around the sun. Lowther's satellite would carry extremely sensitive radio equipment to amplify signals from earth and send them back again on a slightly different wave length. This sophisticated radar system would make no use of the speed of light in its measurements. The distance from the earth to the satellite would be calculated in actual wave lengths of radio energy with an error of only...
What McNamara will find is a remarkable U.S. military effort, mounted in the few short months since Washington decided last October to hold South Viet Nam at all costs. At Saigon airfield a steady stream of huge Globemasters unloads tons of electric generators, radar equipment, trucks and Quonset huts. More than 80 H21 Shawnee helicopters at four airbases are serviced by U.S. ground crews, flown by U.S. pilots-including such colorful types as Lieut. Colonel Archie Clapp, who has lent his name to his squadron, "Archie's Angels." The converted aircraft carrier Core steams regularly upriver to Saigon, carrying...
...national science policy and nurture neglected basic research. Set up in 1950 as an independent agency within the executive branch, N.S.F. is governed by the 24-member National Science Board, appointed by the President for six-year terms, plus Director Alan T. Waterman, a onetime Yale physicist and researcher (radar), who has been on the job since he was first picked by President Truman...
