...less than three years, as the first Catholic President of the United States." And an NBC-TV producer named Lou Hazam spoke boastfully about his Kennedy documentary (one of several commemorative efforts by networks) because his crew had shot the route of Kennedy's funeral procession in infra-red film: "It turns the sky black, the leaves on the trees white, and we get a 'broody' look...
...field. And once on active duty, the new sighting devices should prove to be a marked advance over the famed snooperscopes that were so useful in World War II. The trouble with the snooperscopes was that they needed their own light source -a searchlight that illuminated targets with an infra-red beam. That was invisible to the naked eye but could easily be seen by an enemy equipped with relatively simple detection devices. The snooperscope sniper often found himself a sitting duck, his, own infra-red searchlight pinpointing his position...
...Stars. Where Tiros was aimed uselessly out into space much of the time, Nimbus forever focuses earthward - the result of infra-red controls, which utilize warmth radiated from the earth to keep Nimbus pointed in the right direction. This alone means four to five times more cloud cover photographs. Nimbus' size (830 lbs.) is its greatest advantage, allowing room for a set of daylight cameras that take photos five times clearer than Tiros' best cameras took, and enough batteries on board to supply transmitters with 450 watts of power v. 20 watts for Tiros...
Nimbus passes close to the earth's poles instead of following an equatorial orbit as Tiros did, thus covers a new 1,500-mile-wide swath of the earth ev ery 100 minutes. Nimbus can photograph every square mile of earth twice a day; special infra-red radiometers shoot "pictures" of the dark surfaces...
...Force Cambridge Research Laboratory that carried a telescope above nearly all of the earth's atmosphere. An automatic pointing device locked on the sun and used it as a reference point to focus the telescope on Venus. Then the telescope photographed the spectrum of solar infra-red light reflected from the top of the cloud deck...
